J. Solon Jr. Vice President Environmental Manville Corporation Affairs Good morning gentlemen you ._ We're glad to be with We'll plunge right into our subject because we have a lot of ground to covear nd we're mindful of the fact that your time is a very valuable commodity Our subject is asbestos and health It's a subject we feel we know quite a bit about and we want very much in this tratno tsram nsmi it t as much of that ~~ knowledge toyou as we can Our M team of presenters are all competent people t+ who have been involveidn this field for a long time I believe they'll be able to answer most of your questions - and we are willing to stay right here until the last question answered | oo ee dae- . : 2 he te oe. : Me. Cr ay seer aTn Os N awe We are going to attempt to give you not the other side of the asbestos question rather the perspective ... in its proper context and based on hard facts the material is brought up the bronchial tree so it can be removed -- in some cases swallowed in others spit out So we have discussed two dust collection systems ' The first is the hairs in the nasal passages the second is the cilia system There is a third called the macrophage system which we'll discuss later Now a word about the site of the diseases -- where they usually occur First we have asbestosis-which is one of the pneumocniosis diseases There are several diseases that fall into the category of pneumoconiosis Siderosis is one which is caused by the inhalation of fumes or dust containing iron particles silicosis is caused by inhalation of free silica or quartz dust anthracosis commonly known as black lung disease is caused by inhalation of coal dust byssinosis is caused by excessive inhalation of cotton fiber dust and of course asbestosis which is caused by the inhalation of asbestos dust These are all pneumoconiosis They are cancerous-- pulmonary abnormalities Although these diseases can occur anywhere in the lungs they usually occur in the lower lobe and both lungs could be affecte andd usually are em The next disease that can be causebdy asbestos smoking and a few other things is bronchogenic cancer Now just the mere mention of the word cancer is enough to frighten many people and it is the kind of sensational headline word the press often likes to latch onto Bronchogenic cancer while it can occur any place in the lungs usually develops at the major junctions of the bronchioles -- up in the central part of the bronchial tree Bronchogenic cancer is caused by many agents including asbestos One of the leading causes of bronchogenic cancer among both asbestos workers and asbestos workers is cigarette smoking The third disease is called mesothelioma -- which is another form of cancer It affects the lining of the pleural cavity or it may affect the lining of the peritoneum -- which is another name for the lining of the abdominal cavity _ Mesothelioma is by far the most diseases I've described It is serious of 100 fatal the and three there is no treatment for it Death usually occurs in 18 months It is however an extremely rare disease It is not caused solely by asbestos There are other agents which cause mesothelioma ~~ in fact there are now more cases | of mesothelioma listed in the world registries where asbesto hass not been involved there are cases where I'm sure anyone who uses asbestos fiber in his plant and who reads the popular newspapers or magazines must have asked himself at one time -- what's the truth behind all this talk of asbestos and health hazards Unfortunately the popular press is out to sell papers and usually presents the sensational side of a question But there is another side - the medical scientific press -- which is mainly there to convey knowledge and usually presents the more factual side of health questions While there are two sides of this question -- the sensational and the factual -- there remains but one question that is important to all of you Can asbestos cause a health problem In all honesty we may say yes Asbestos can cause health problems if it is improperly used or improperly handled If an employee or person is subjected to high levels or air- borne asbestos dust in the air he breathes serious health problems can result But if the person is protected -- if the normal prudent dust control systems which we will discuss later are instituted -- a person's health can be safeguarded and he or she can still work with asbestos fiber Just about everything has a dose relationship when it comes to health and asbestos is no exception Every product we use in our plants every product we use in our homes ~ _ ~~ owe oe aS ee is potentially dangerous It doesn't matter what it is -- whether it is asphalt or asbestos in our plants or whether it is cooking flour or table salt in our homes They are all potentially dangerous substances if improperly used But properly used they can be of great benefit in our everyday life and in our industrial processes Yes there is a safe level for exposure to asbestos -- very definitely a safe level <= and this is what we have come to talk about This level is one which a person can be exposed to and yet suffer no ill health affects There are other questions I'm sure you would like to have answered How was this safe level established what diseases are caused by asbestos exposure are there different health risks from the different types of asbestos We'll discuss those and the biological reaction of human tissue to asbestos fiber But before doing that I think it would be wise to briefly review some of the anatomy of the respiratory SLIDE The air we breathe enters through these passageways in the nose down into the trachea which is the round -- ae The trachea separates into two main passageways called the bronchi -- a left and a right -- and the bronchi in turn get smaller and smaller as they go down the bronchial tree They just keep dividing into smaller passageways until they reach the bronchioles and then later a portion of the respiratory system known as the alveoli SLIDE We often refer to the respiratory system components as part of the bronchial tree and you can see why it is called a tree Here again we see the same trachea-the left and right bronchi -- and how it divides gradually This is a very important area to remember when we talk about the formation of disease later SLIDE wee oe I mentioned that the ually into alveoli small passageways terminate That's what we have here event- these like structures are called alveoli and here is where all the action takes place as far as our respiratory system is concerned These small structures are encapsulated with minute capillaries -- blood vessels -- and it is here where the oxygen and carbon dioxide areexchanged Incidentally there are 750 million of these small alveoli in the human eenad lungs This again is important to remember we talk later about we have 750 disease million destroying these alveoli of these small structures Since several thousand even several million can be destroyed without any adverse effect upon a person's normal respiration SLIDE This part of the human respiratory system is refer we to as a garbage collection system -- what own filtration system It begins with the small hairs in the end of your nose These are filters -- they filter out the larger asbestos fibers the larger particles of dust or anything else you might inhale This area here in the inner nasal passages and down into the trachea into the smallest bronchioles are lined with what are called cilial cells These are small cells with a whiplike structure protruding from the top There are literally millions of these cells lining this particular cavity and their function in this waste filtration system is to sweep the dust you inhale out up from the lower depth of the bronchioles all the way up the trachea out so they can be removebdy expectoration These cilial cells are coated with a mucous layer which catches the dust particles with sweeping motion Page 4 Today products containing asbestos are in our homes schools factories offices hospitals theaters spacecraft ... and I could go on and on The point is '... there is no one material that can outperform asbestos economically or in quality in the majority of these applications ... and indeed there are many products that without asbestos could not be made at all nor could they do the job they were intended to do Asbestos fiber is more in demand today than ever before and we have expanded our mining and milling facilities again to meet that demand Yet ... even the 75 million we just finished spending on a new mill at our Jeffrey Mine in Canada is not going to enable us to provide asbestos fast enough to meet all the demands of all our customers We'll get there ... but we are finding the pacea little faster than we expected Now let's talk the health problem ... and let me be quite frank No matter what has been said nor how much has been learned about the asbestos problem we didn't have to do anything We could have just sat back continuing to sell as much fiber as we could deliver and let the other guy the government or someone else worry about the health problem and what to do about it Yes we could have done that Page 5 But gentlemen we didn't ... and never will that's Fact Two And For the last century ... from the first indications that there was a health problem involving workers who inhaled too much asbestos dust ... we have taken the initiative We didn't wait for someone to tell us what the health risks were ... we sought them out And M wasn't the only company to take action ... the asbestos industry as a whole has been active in asbestos health research both here and abroad for some time Together we have funded and encouraged a great many studies We have worked with Federal State and Local governments in eliminating problems and setting appropriate exposure standards And at our own M Research laboratories in Denver we are not only conducting research into asbestos but into many other materials In addition we frequently cooperate with other researchers and groups by supplying fiber samples for study In short gentlemen we have always put our money where our corporate conscience was Page 2 We won't insult you by contending we're not biased - on this subject But ... let me assure you from the start that this is not going be a propaganda session We have nothing to gain by trying to hide the facts or cover them with meaningless rebuttals At Manville we firmly believe that while it is dangerous to pretend there is no problem and do nothing it is just as dangerous to pretend the the problem is so great that total abstinence is the only cure Our customers ... and indeed your customers can ill afford to live with either extreme Between the time any health problem is identified and the time a cure or final solution is found there is always a period of prevention and control That is the period in which we find ourselves now And it may well be that prevention and control will be the cure in this instance We already have indications to that effect Now those are concepts and what you want are facts Let's start with three ... Page 3 Fact One Manville is the leading producer of asbestos and containing products in the U.S. +++although this still accounts for less than half of our multinational business We know better than anyone else I would imagine how indispensable asbestos has become in our modern society You've probably heard that asbestos now is used in some 3,000 different products worldwide oe. most of them in daily use Speakinogf asbestos let's make sure we review the facts on our main character Asbestos is the name given a family of fibrous minerals -- not one form or one product These minerals have in our environment for as long as occurred naturally our planet has been in existence Characteristically asbestos minerals are resistant to extremes of heat and cold are flexible lightweight and durable as you know There are four commercially significant varieties of asbestos use today . and one variety chrysotile asbestos accounts for 97 of all the fiber used in the United States The other commercials forms of asbestos are crocidolite amosite and anthophyllite a nd it is important to remember that these three forms differ from chrysotile physically and chemically as well as in use _ ~- a er ee Page 6 We weren't always happy with what we learned Frankly no one likes to learn that because of a lack of knowledge not just on their part but on the part of the scientific community labor and government that the health of some employees was unknowingly endangered But ... neither did we hide from the fact once it was knowTI ... and that brings me to Fact Three M also has been a leader in cleaninugp ... in controlling those occupational hazards we helped identify When the equipment did not exist to control a certain situation we developed it In fact some of the equipment and systems we developed to control ourproblemarse now being used by other industries with similar problems We have a coprorate policy at 5- ... a policy that has been quite widely publicized ... and one which we all live by Since it puts what I have been telling you in perspective bear with me while I quote it Page 7 It is our Company's policy to equip our plants for the highest degreoef personal safety ... provided it is technically possible and economically feasible to do so When technology is not available .. or when it is not feasible economically from a competitive standpoint to make these installations I can assure you we will elect to discontinue a particular operation aa rather than knowingly endanger the health or life expectancy of a single employee We believe in this philosophy We believe that you must agree with this philosophy or you wouldn't be here today . to listen to learn to discuss You want to know what the asbestos question is all about and what it means to you You want to know how to control occupational hazards how to comply with new regulations You want to know I'm sure what M has done to make your job easier ... as well as what we are doing and are willing to do for you in the future Page 8 Those are the areas that our four speakers will address themselves to this morning Afterwards we'll open up the meeting for your questions Ed Fenner who is Director of Technical Relations in our Environmental Affairs Department will discuss OSHA and EPA standards He'll tell you what the standards are and what they mean to you He'll also tell you what you might and what we and the industry expect in are doing the future to strike an acceptable balance between extremisomn both ends of the spectrum Ed a year veteran with M earned a B.S. degree in Mechanical Engineering from Worcester Polytechnic Institute in Massachusetts Prior to this assign- ment he was Director of Environmental Control for the company and had all of our industrial hygiene laboratories under his direction After Ed you'll hear from Noel Hendry who is vice president of Manville Sales Corporation and general sales manager for Asbestos Fiber A year veteran with Manville Noel earned an engineer- ing degree from the Universitoyf British Columbia and a master's degree in geology from Cal Tech He of course is responsibfloer all of us being here . today ~_ , Page 9 Noel will focus on a topic I'm sure -~ is of interest ... what M is doing to eliminate any dust problem for you -- our customers You'll find that we have done =a, a lot and are willing to do a lot more to help you ee with your particular situation - Next you'll hear from Don Hillier our Director of Environmental Engineering Don earned an engineering degree from the University of Michigan and began his career with the Armstrong Cork Company as an industrial engineer At M he has progressed through a number of production engineering positions to his present assignment as head of Environmental Engineering With this background Don is well qualified to discuss the various fiber handling methods we have developed within M and how they can be applied to your individual situations I'm sure Don is going to tell you that dust problems not only can be controlled but that in most cases the equipment technology and expertise are available now Our first speaker is Bill Reitze Corporate Manager of Accident Prevention and Industrial Health for Manville Page 10 Bill Reitze's knowledge is recognized in the health field ... he holds a degree in chemistry and has done graduate work in physiology And he has had extensive experience in medical research toxicology and industrial hygiene Let me now give the podium to Bill Reitze --. SLIDE Getting back to the cilial system since it is extremely important that we discuss our built defenses against dust In this microscopic section showing the cilia you will note the like whips which sweep the dust particles that adhere to the mucous layers up and out of the body SLIDE a In this oversimplification of the bronchial tree you can see small outpouchings Usually asbestosis starts here in these small outpouchings SLIDE Now about the biological reaction to asbestos fiber When an asbestos fiber is inhaled into the body -- and this applietso many other types offibers - a few things can happen Either the fiber is encapsulated in what we becomes refer to coated as macrophages It becomes what or giant cells and some call an asbestos body but is more scientifically referred to as an ferruginous body The other alternative is that it remains in a naked state -- uncoated If the fiber is encapsulated and becomes a ferruginous body then the fiber for all intents and purposes is harmless If the fiber remains in a naked state then a biological reaction may begin you get cell proliferation -- an almost uncontrolled growth cells Collagen is formed which is another name for scar tissue similar to what you get on a cut When collagen it destroys the tissue -- you no forms in the lungs longer have a functioning unit there is no more exchange of oxygen and carbon dioxide Your vital capacity in this case is greatly reduced -your lungs can't hold as much air as they did before because these alveoli have been destroyed Because this vital capacity is reduced you also alter your bloodgas exchange and the overall effect is poor ventilation and belabored breathing a How do we spot this in patient -- what are the symptoms It's done two ways One is_by ray where several views of the chest are taken The physician looking at the ray can spot various types of shadows all of which will mean somethingto the trained radiologist The physical symptoms are unusual noises called rales which the physician can hear with the aid of a stetho- scope Rales can be caused by bronchitis colds pneumonia and a number of other things besides asbestosis Another physical symptom is clubbed fingers Why this occurs is a mystery It may be caused by the alternation in blood gas exchange Continuing on asbestosis the first noticeable signs usually are that a person gets very tired on exertion and has difficulty breathing - As far as bronchogenic cancer is concerned the biological mechanisms in the development of this disease are not really that like mesothelioma well When understood It is a cancer| we unlock the mysteries of these diseases as well as other forms of cancer I'm sure we all will be very happy SLIDE Now about the different types of asbestos and their roles Chrysotile as I mentioned is the most used form of the fiber in this country and comes mainly from Canada It is usually referred to as the white fiber We have crocidolite -- or blue fiber m= which is found largely in Africa The third major type of fiber is amosite or brown fiber again found mostly in Africa SLIDE There are chemical differences in the types of asbestos and the most significant one is in the magnesium content as you see here chrysotile has 38 magnesium while crocidolite and amosite have virtually no magnesium This is a major chemical difference in the fiber types Anthophyllite whicihs used in plastic reinforcement and is largely supplied by Finland is similar to chrysotile in chemical composition and from a biological point of view as well The important thing to remember is that the usage in the United States is primarily chrysotile asbestos SLIDE The physical difference in the fibers make a very big difference in the biological reactioonf the fiber to the human tissue In this 400 magnification of crocidolite -- the blue fiber -- we notice that the fiber is rod- shaped The size differential is tremendous -- they go from particles less than one micron in length up to 50-60 microns <-- all harsh very rigid fibers Amosite has basically the same physical characteristics SLIDE Now when we look at chrysotile we notice there are some differences in the type of fiber This Canadian chrysotile from our Jeffrey mine Notice how flowing these fibers are how they resemble wool in their appearance They are not rigid rods such as the other types particularl the crocidolite SLIDE NOW what does this mean in terms ofbiological effect on the lung tissue Again in this schematic of the bronchial system we see a harsh fiber like crocidolite and here the softer fiber like chrysotile -- both approximately the same diameter and length Yet when we inhale the harsh fiber it tends to zip right down the bronchial passageway However chrysotile because of its like appearance actually presents a larger fiber diameter and these fibers tend to impinge on the sides of the smaller broncioles where they are brought up by the cilia systems so the body can get rid of them Therefore the physical characteristics of a fiber are extremely important in relation to its biological reaction In order to cause pulmonary disease a fiber or particle must penetrate deeply into the lungs In order for a particle to penetrate deeply into the lungs it must be below 3-1 microns in diameter In the case of a fiber the diameter must be below 3-1 microns but the length can be considerably above that figure SLIDE It was with that thought in mind that investigators decided to find out if there is a difference between the clearance rate in lungs of the various types of fiber This study was undertaken with a group of rats which were exposed to known concentrations of the fibers One group of rats was exposed for 30 days to crocidolite another to amosite and another one to chrysotile At the end of 30 days some of the rats were sacrificed and an estimation made of the amount of asbestos fiber in the lungs of these animals These figures show the amount present at the end of 30 days exposure Thirty days later another group of these same rats was sacrificed and the amount of fiber measured An then 30 days later the third group of rats were sacrificed From this graph you can see that the results of this study showed that chrysotile is more readily cleared from the lungs than either amosite or crocidolite SLIDE I mentioned that another of the cleaning mechanisms in the body are the macrophages -- which are large cells that encapsulate the fiber it enters the tissue is what they look like This By process of encapsulation the formation of asbestos bodies -- or ferruginous bodies -- takes place SLIDE Here we have a more advanced stage of the disease in a guinea pig We can see the beginnings of the disease in these outpouchings -- which I described earlier SLIDE A natural progression again is shown in this slide The darkly stained areas are where the disease is beginning to develop destroying these small structures I pointed out before As I said we have so many million of them you can destroy a few and not even know it SLIDE Here we have further destruction of this particular tissue Collagen is beginning to form and once this area is covered by scar tissue the normal respiratory function ceases in that particular area SLIDE Here we have further formation of collagen or scar tissue Looking closely we can see small black lines which are the fibers -- in this case about one micron in length These are crocidolite fibers -14- SLIDE . Now asbestos bodies in themselves are not harmful Once the fibers have been coated they become harmless from a biological point of view This is what an asbestos body looks like In this case we are talking about an asbestos fiber but it can be any type of fiber around which an rich protein substance is formed SLIDE Here we see the inner fiber coated with rich protein SLIDE Now about dosage standards How do we know that the federal regulations of five fibers per cc now are the safe levels This chart was taken from the study of Dr. Corbett McDonald who is head of the Department of Epidemiology at McGill University in Canada He dida survey of almost 10,000 Canadian miners and millers of asbestos in Quebec's eastern townships Two separate groups were used one at Thetford mines and the other at our Jeffrey mine operations in Asbestos Canada almost identical The results are -15- In analyzing these figures we see McDonald used both the number of years of exposure and the exposure level itself Some investigators use only one or the other but most epidemiologists believe that unless you use both the exposure level and the number of years at that particular exposure level your figures are not valid Dr. McDonald uses both here Dr. McDonald's work clearly illustrates that the ill health effects of asbestos exposure are not seen until. the exposure levels excee2d0 to 40 fibers per cc SLIDE Again this is a chart adapted from Dr. McDonald's - study and again we see the death rate is insignificant until we get up to higher levels where we really have some significant health changes This is how we have established that the five fibers per cc level is safe SLIDE Here we have a comparison of three studies The first of 632 insulation workers -- a very small study was done by Dr. Irving Selikoff of Mount Sinai Hospital in New York These workers were exposed to Canadian chrysotile amosite and crocidolite plus they were exposed to solvents and other dusts These are the men that cover materials the piap nde dus cts with oe. asbestos insulation -16- The second study was done by Dr. Molly Newhouse in England and involved factory workers only Again factory the workers here were exposed to three different types of asbestos but probably not the mixed dust and solvents to which the pipe workers were The last study is Dr. McDonalds -- 9,981 people - a population that was exposed only to Canadian chrysotile It is significant that when we look at the rate of lung cancer and mesothelioma can see that the higher in these rates of different groups you these diseases were in groups exposed either to all three types of asbestos and other materials or all three types of asbestos alone When we look at the figures for those workers exposed only to Canadian chrysotile we see quite a difference The percentages are very low -- almost nil on mesothelial tumors SLIDE |. _~ This study revealed some significant facts It is adopted from Dr. Phillip Enterlines of Manville retirees from our study of a operations group all around the country The significance here is that it wasn't our production workers who had the heaviest ex- posure rather our maintenance service workers -- the people who sweep the floors systems repair broken bags maintain the dust collection and so on They will have a heavier exposure and therefore th should be carefully -17- Let me stress here that all these deaths I have been talking about -- from asbestosis bronchogenic cancer and mesotheliomaand mesothelioma<-- are the result of exposures that _ es = took place 20 30 or 40 years ago before we knew there were any problems -- and before the medical - scientific community labor and government realized the severity of the problems These diseases particularly mesothelioma have a long latent period They take many many years to develop even the first symptoms SLIDE Here we get an idea of what good dust controls can do to solve the problem This is a study done by Dr. John Knox who was medical director for Turner Brothers in England In this particular plant there was no dust control at all until 1933 they decided to install dust control equipment | He divided his plant population into three groups Group one had over 10 years work experience in this one plant prior to any installation of dust control equipment Group two were those who had some exposure prior to 1933 -- prior to dust control installations -- but less than 10 years -18- Group 3 had no exposure prior to 1933 and the installation of dust control equipment However of these people had at least 30 years exposure - either with or without controls all Now in the group with the heaviest exposure before controls they expected to have about 10 deaths but in reality they had In group two with some heavy exposure prior to controls they expected 8.4 deaths and they got 6. And in the last group which worked only in the plant after dust control equipment had been have installed we 5 deaths from see that while they expected lung cancer they only had two a that So we can see dust control equipment does pay off -- and from this study we can see that the results are dramatic by the use You can of dust protect control the lives of equipment your people SLIDE - Another important point is that smoking and asbestos just do not mix In this adaptation of Dr. Selikoff's work it is significant that the cases of bronchogenic cancer all were in asbestos workers who also smoked cigarettes Those asbestos workers who did not smoke cigarettes had no greater rate of bronchogenic cancer than the normal smoking population Based on these hard facts about the carcinogen effect of smoking and asbestos dust inhalation we at Manville have done all that we could to discourage our people who work with asbestos- smoking among SLIDE Now as I conclude let me say a few words about the difference in asbestos products I'm sure you are getting questions from as Will this product your own customers -- be harmful to the end such user Basically asbestos products fall into two groups << the bound products and the unbound products In the unbound products you do have to be concerned with of the generation dust In those products that are bound by physical chemical or thermal means there is little cause for concern since the normal use of these products will not release significant amounts of asbestos fiber into the ambient air SLIDE What all this means can be summed up in a very few words we First of all must realize that asbestos can cause some very severe health problems if the proper steps are not taken to reduce the exposure of the individual But these health risks can be controlled There is a safe exposure level for asbestos can be handled safely it can be used by the end user -- the consumer consumer -- safely I think most of the responsible scientific people in the country today feel that the levels that have been established by the Federal government under OSHA-five fibers per cc weighted average and 10 fibers per cc peak average ~- are safe levels for any employee And that includes all the diseases I mentioned All these diseases are preventable if proper dust control measures are taken Asbestos and Health Presentation December 3 and 4 1973 Fibre Handling Systems Presented By N. W. Hendry Vice President Manville Sales Corp. General Manager Asbestos Fibre Division Manville Corporation ASBESTOS & HEALTH PRESENTATION BY N. W. Hendry My subject is Asbestos Fiber Handling In addition I will show you some of the things we have done and are doing at Jeffrey Mine in this regard By way of introduction and since I will be speaking of the Jeffrey Mine here are some of the major features oa. . slide 1 The Jeffrey Mine is the largest producer of asbestos in the world with annual production in excess of 650,000 tons annually It is located approximately 100 miles east of Montreal in Asbestos Quebec Canada The Jeffrey open pit is over 1 mile in diameter and 950 ft deep For six days a week some 35,000 tons of ore are hauled to the crusher and more than 100,000 tons of waste rock and overburden are hauled to the waste dump wy at slide 2 This is mill 5 with the fiber storage warehouse in the foreground Mill 5 is 12 stories high and . ; has 20 primary rock processing lines Slide3 Slide3 slide 4 This is an overhead view of the 72 Gyratory crusher which is handling at present 35,000 tons of ore daily This crusher replaced 4 jaw crushers This is a view of the upper portion of the concentrator dryer complex The entire complex is under rigid dust control note there is no visible emission from the dryer stacks As you realize asbestos fibre is very important to our division We produce and sell upwards of 775,000 tons annually from our 4 mines Our objectives are to deliver asbestos fibre to our customers in a form and in a manner in which there is no dust problem and such that the employees of our customers have no actual contact with asbestos Many of the methods and systems which I plan to describe to you today will accomplish these objectives We are prepared to work closely with your personnel to assist you in the achievement of these same objectives By way of indicating our confidence in the future of asbestos fibre we have completed an expenditure of 75 million dollars in locating and in expanding our mining equipment at the Jeffrey Mine Tm Now let me describe briefly some of the things we have done and are doing relative to fibre handling THE BULK TANK CAR We have in conjunction with the Ford Motor Co. and Procor in Oakville Ontario developed a bulk tank car and we have been shipping short asbestos fibre grades in it on a successful basis over the past 3 years C.J.M. alone spent approximately 150,000 in the development of the car slide 5 Slide 6 This car will hold 55 to 57 tons of the fibre grade being supplied to Ford we have 6 bulk tank cars supplying the Ford plant requirements This is a schematic of the bulk tank car with a listing of the specifications and working data We load the car at the mine by pumping the fiber into the 7 compartments At the receiving location plant air is attached to the car to fluidize the fiber and cause it to flow into the storage silos The contained fibre can be pumped out in 4 hours Slide 7 This is a storage silo at Jeffrey Mine with a capacity of 25 tons A Vibra screw hopper on the bottom is essential to keep the fiber from packing Slide B megs This is fiber pump in use at Jeffrey Mine to load the car There are 1 2 definite limitations to this system including The length and openness of the fibre The capital investment required - the investment is in the order of 100,000 and on a rule of thumb basis it does not appear practical unless annual usage is in the order of 2000 tons Advantages of the bulk system include 1 No handling of bags 2 No contact with fiber by personnel 3 Lower handling costs 4 .. East of monitoring dust levels The entire bulk fibre system at Jeffrey is monitered for dust control and fibre counts are maintained under the 5 fibre level 2. PLANT FIBRE HANDLING SYSTEMS slide 9 This is a schematic of an plant fiber handling system based on equipment developed and tested at Jeffrey Mine The system includes a bag breaking station and a fiber pump The fiber is pumped to the mixers or to weight hoppers The entire system requiring approximately 3,500 cu of air The cost of this system would be in the order of 14,500 plus the cost of piping slide 10 we gs We have developed cost estimates the installation of a bulk fiber system The figure of 96,000 is a reasonable estimate slide 11 We have talked about a fiber pump which is a C.J.M. development but there are other items of equipment on the market which can be used to transport fiber One such item is the Vanco Blower This model can move 100 lbs per minute of GP 7 fiber We have several such systems at Jeffrey and we are moving fiber 35 ft vertically and 2000 ft horizontally with these units with the entire operation under dust control There ' are two models of this Vanco Blower ranging in price fromflto 3,000 3 THE AUTOMATIC BAG OPENER slide 12 Slide 13 Slide 14 This is an automatic bag openears developed by the Jeffrey engineers The operator places pressure packed bags on the feed conveyor and the bags can be paper cr polyethylene and the machine cuts the bag automatically dumps the fiber into a chute and deposits the bag at the far end This part is the bag disposal section A bag baler under development to automatically bale the empty bags slide 15 mg ee, Here you can see the detail of the dumping mechanism The contentosf the bag are dumped intoa bin and the empty bag is carried to a disposal station Dust control requires 800 C.F.M. of aspirating air and dust counts taken through the complete cycle were less than 2 fibers C.C. The cost of the machine ranges from 9,900 to 12,500 depending on the various controls specified Fairmount Engineering Inc. of Hackettstown New Jersey has developed a bag opener which appears to have merit the quoted price is 8,500 4. PLANT HANDLING SYSTEM slide 16 This is a fiber handling system employing the bag opener The fiber feeds to a Vanco blower The capacity of this system would be approximate 10 tons per hour Our estimated cost of this system installed in a plant is 29,000 and that would include a bag baler 5. FIBER PACKAGING slide 17 standard Here are our 3 types of pressure packed bags being used to package fiber in the domestic market 1 Standard Kraft multiwall paper 2 6 mil polyethylene film 3 Pulpable Kraft paper multiwall bag This slide illustrates a very important concept in fiber handling use in the For example the pulpable bag was developed for asbestos paper industry so that bag and contents could be dumped into the Hydropulper or vat thereby eliminating the need to have a man open the bag In the same way the polyethylene bag is used in the asphalt paving in- dustry and in limited cases in the bag and contents are dumped the floor tile industry Amain into the pug mill or mixer Unfortunately this concept is limited to suitable materials which can be constructed as of the bag composition with the product well as the compatability compatability formulation 6. UNITIZATION UNITIZATION UNITIZATION Slide 18 Here we have a ton unit consisting of 45 pressure packed bags The unit can be shipped on a cardboard deck sheet or a wooden pallet and the bags can be glued locked Similar units of one or two tons can be shipped if required Slide 19 aw. a, Shows the same unit covered by shrink polyethylene we have the equipment at Jeffrey to shrink poly film if our customers request it Unitized shipments of asbestos fibeirn bags glue locked on wooden pallets with or without shrink poly suffer less damage and undergo less shifting in a car than any other method 7. THE ASSIGNED CAR In seeking added measures to insure improved condition of arrival of asbestos in bags we have developed the assigned car plan Over the past 18 months approximately 450 cars each 40 ft long with double doors have been in assigned service to J.M. plants in the United States Under this concept we unitize and glue lock the pressure packed bags on wooden pallets and employ inflatable dunnage to stabilize the load slide 20 This is an assigned car loaded with bagged units on wooden pallets with inflatable dunnage slide 21 Here you can see the inflatable dunnage in more detail there are two bags in each car slide 22 Here are the wooden pallets in more detail They are heavy duty double faced four way entry style hardwood pallets -. Our experience over the period of 18 months has been excellent whereby shipments has been the condition of greatly improved arrival of the asbestos over previous standards A limited number of these assigned cars inflatable dunnage bags and pallets are fully equipped with available for test shipments If after receiving a trial shipment you decide to accept this new concept we estimate it will take approximately 6 months to acquire the necessary cars and dunnage Our experimental work on improved asbestos fibre handling systems is continuing in two directions 7 awe 8. HIGH DENSITY BLOCKS slide 23 Shows a compressed block of fiber measuring 9 x 12 x 16 with a density of 100 lbs./cu ft For comparisoins a standard pressure packed bag of fiber having a density of 50 lbs./cu ft The blocks are dust free and our evaluation work a large paper manufacturer is most encouraging date with Slide 24 slide 23 23 : This is a ton of compressed asbestos blocks on a wooden pallet and covered by shrink poly Here for comparison are an equal weight of pressure packed bags and compressed blocks the difference in cubic content Note meg In addition we have developed a is under evaluation for asbestos compressed paper in paper use pallet which We have engineered and built blocks but more time will be termed a production item a packer required to produce compressed before blocks can be 9. PELLETIZED FIBRE Slide 26 Here you see 100 lbs of pellets weight of pellets in paper bag loose the and for same comparison a standard bag containi1n0g0 lb. of pressure packed fiber We have a Sprout Waldron Pelletizing Machine under evaluation Mine at Jeffrey and have successfully produced pellets with GP 7 fiber grades using water as a binder Pellets have a loose density of 65 lbs./cu.ft and they lend themselves admirably to shipment in closed hopper cars or in bags or in other types of containers They are largely dust free In conclusion I have outlined the work we have done and are doing in the asbestos fibre division to meet our objective of delivering asbestos fibre our customers in a form and in a manner in which there is no dust problem and such that you will have no problem in meeting the OSHA regulations as these relate to asbestos ~~. ~ We will be pleased to work closely with any of your personnel in the development of a fiber handling system that fits yours nf particular requirements 1 Asbestos and Health Presentation December 3 and 4 1973 Asbestos Handling Methods Within Manville Presented By D.

I'm sure that was a lot to digest in a short period of time I hope we covered most of the questions you had on your mind but before we get to those we missed I hope you'll indulge me a few more minutes to summarize As Bill Reitze told you we have learned a great deal about asbestos problems in a short period of time -- because we wanted to learn about them We're still studying and still learning - We learned a great deal at the last major meeting on asbestos and health held a little over a year ago in Lyon France It was there that a majority of scientists from all over the world who are actively studying the bio- logical effects of asbestos met under sponsorship of the International Agency for Research on Cancer ... which is a division of the World Health Organization There were 130 participants from 20 countries at the meeting ... thus the report of that group's Advisory Committee on asbestos cancers bears a lot of weight Briefly these researchers reported Page 12 - There is no evidence of lung damage by asbestos to the general public -- There is no evidence of an increased risk of cancer resulting from asbestos fibers present in water beverages food or in the fluids used for the administration of drugs Regarding lung cancer there is no detectable the committee reported lung cancer risk above that normal occupational when exposure to asbestos has been low ... and further have almost noted that these low occupational exposures certainly been much greater than the amount of asbestotwo his ch the general public has been exposed -- And regarding mesothelioma -- a rare cancer of the lining of the lung or abdomen -- they said there is evidence from population studies thata considerable number of mesothelioma cases have no known association whatsoever with exposure to asbestos A lot more came out of that meeting such as the incriminating evidence against cigarette smoking as a very probable carcinogen And we learned that there are clear differences in risk with the type of fiber and nature of exposure Page 13 Now gentlemen add those facts to others we have known risks for some time -- today are almost that asbestos health exclusively confined to the occupational setting . that the effects of excessive inhalation of asbestos are both time and dose related and thus there are exposure levels that will not result in any increased risk of disease And most of all remember that for asbestos because of the long latent disease the disease being period found today among some time employees is not an indication of present day conditions -- rather it is a result of conditions existing decades ago when neither industry | government nor the medical profession knew very much about the health effects of asbesto..s. and even less about the proper means for their control Today as Ed Fenner told you we have to live with a number in our of regulations plants and EPA and standards -- OSHA standards standards outside them But these standards can be met and we indeed the entire proper industry ... will be in there battling for controls regulations and standards not needless controls and regulations and standards Page 14 Noel Hendry pointed out that we are not only concerned about our problems but yours as continue to make every effort to well assure We will that the fiber you receive from us in no way adds a problem for you And if it does or you need some special consideration because of your operation we want you to call on us to help And I think after hearing from Don Hillier you know we are able to help ... that we have the expertise and the people to help solve your problems START PROJECTOR AGAIN Still there are other ways we may be able to help you As some of you may know we have established an Environmental Affairs and our goals are geared Department at Manville not only toward our own people but to you our customers One of our projects has been the compiling and publish- ing of a number of position papers on Asbestos and Health SLIDE Asbestos Family of Minerals paper Asbestos Family of Minerals is one It describes the characteristics of the four commercially signi- ficant varieties of asbestos Page 15 . SLIDE Lyon Report paper paper Report Another is titled the of the Advisory Committee on Asbestos Cancers to the Director of the International Agency for Research on Cancer which we have nicknamed the Lyon Report It outlines the major conclusions from a of respected researchers 1972 from meeting in Lyon France all over the world who were studying the biological aspects of asbestos and health SLIDE Asbestos and Health paper The third paper Asbestos and Health discusses the occupational health risks from asbestos dust and what- M and the industry has done to eliminate or control them SLIDE Q & A paper Paper number four Questions and Answers on Asbestos and Health provides answers to the most commonly asked questions about asbestos and health SLIDE A Water Pipe paper And number five Asbestos Water Pipe and Health discusses the results of studies to determine if drinking water that has passed through asbestos- cement water pipe poses any health risks Page 16 We are planning a few more one which discusses studies on the asbestos health risk to the public the and other on environmental health research supported by M and the asbestos industry as a whole You will find copies of the five position papers I mentioned in the folders we will hand out in a few minutes along with an order form in case you want more In those folders you'll also find eee SLIDE Poster and Brochure oe a copy of this poster on Safe Handling Practices for Asbestos Fiber and a small pamphlet which contains the same information These were produced mainly for our customers and others who might find them cou andr of s coue rse they can be found through- out our plants If you would like to order some of these for posting on bulletin boards or distribution to employees just fill out the order form in the folder and send it to our Service Center SLIDE Green Asbestos Employee Booklet , Page 17 Another project of ours which you might find of value to you is this employee booklet on What Every Employee Should Know About Asbestos been has distributed to all our people and It it is available to if you would has been set you and your employees In fact rather not have M's name on it it up so that we can easily reprint your company name on copies ~- even though that would have to be done at your cost ... which would be minimal I also know that Noel's group is planning a newsletter for Asbestos Fiber customers to keep you all up to date on what we are doing and what is new in the area of asbestos and health And lastly I call your attention to the fact that we have established medical library in our deparment a We have copies of fairly extensive | most of the important medical studies on asbestos and have copies making available to anyone who been and will be needs them You're welcome to give us a call man to get in touch with is Walt Cooper we'll try to provide any information you may need TURN OFF PROJECTOR Page 18 Sc there is a lot we want to do and can do for you The first step however is yours As Don said we know don't what your problems are or - even if you have them any But if you do we and work out a solution can help you identify What it all boils down to is this We will continue to work towards assuring that customers control any health not only problems we but our that may be involved with asbestos We will never take the position that the benefits of asbestos 7" or any other material for that matter - outweigh all the health risks What we will maintain is that the growing need for asbestos demands something that we believe M has and something you have proven you have by your presence here today That something is conscience All that remains now is for us to together to turn that conscience into action PAUSE And now gentlemen and ladies let's have any questions that remain on your minds You can direct them to me or to any of our speakers Page 19 Aster Questions Now before you leave . I would like to have my colleagues hand out to you the facts folders we have prepared especially for you Aside from the position papers the Safe Handling poster and pamphlet a copy of our employee asbestos booklet and the order forms - I mentioned you'll also find a set of the five booklets published by the Asbestos Information Associa- tion this pocket size reference guide on OSHA and this Facts About Asbestos Booklet published by the Quebec Asbestos Mining Association a Also in the back of the room we havea number of copies of today's presentations If you would like to have a transcript of the talks given by our team today be sure to pick one up as you leave Now let's adjourn for lunch
