JACOBSEN, Safety Chairman, Oil, Chemical, and Atomic Workers Local 4-447, Destrehan, La. The judges were impressed with Brother Jacobsen's tenacious efforts on behalf of safety in his local union. The documented material vividly revealed the many extensive activities he promoted and participated in. It also showed the amount of time and energy he unselfishly put forth to promote safety. The judges noted the many areas of ac tivity in which he is engaged, including safety training, and the fact he was not deterred in achieving noteworthy goals. The Awards committee of the Labor Conference warmly commends him for his solid achieve ments. OCCUPATIONAL HAZARDS-- MAKING THE INVISIBLE VISIBLE By RALPH NADER Attorney, Author, Safety Critic, New York, N. Y. The chief forms of domestic violence affecting American working men and women are motor vehicle crashes and occupational dangers and diseases. Taken together or singly, their toll in death and injury utterly dwarfs the violence incurred -through street crimes. While the nation is properly con cerned about street crime, it virtually ig nores the far greater death, injury, and wage losses on farms, in mines, factories and open work areas such as construction sites. Consider one comparison out of many that could be detailed: all the riots in this country during the past three years in our cities have led to about 260 dead; each working day brings death to 55 workers, disabling injury to 8,500 workers and lesser injuries to 27,200 other laborers. Every year, 14,000 to 15,000 workers die, over half a million are disabled by occupational diseases, over two million are disabled by occupational accidents, and over seven million are injured. The toll is even greater than indicated by the above data because death through toxic exposure over time to chemicals or particu late matter is rarely recorded. The half million plus workers disabled from the ef fects of asbestos, beryllium, carbon mon oxide, coal dust, cotton dust, cancer-causing chemicals, dyes, pesticides, radiation etc. must be taking terminal doses over time from some of these exposures. There is another reason why the above data must be con sidered understated--a reason which leads to the first of six realities which should be recognized publicly before significant prog ress can be made to reduce worker injury and disease: 1. Under-reporting by industrial firms of actual injuries and disease experienced by laborers has long been an endemic mana gerial disease. First, the definition of what constitutes an injury is decided by an indus try-dominated body called the United States Standards Institute of America--a group of industries and industry technical societies. Second, companies go to considerable length to avoid reporting a lost time injury--not only to keep their insurance rates down but to preserve their place in safety competi tions. For example, a worker in a Jones & Laughlin steel plant received a groin injury; he was taken off his usual job and placed in a chair where he sat doing nothing for two weeks. Any blue-collar man knows that such a practice is not unusual in numerous industries. 2. Plant physicians surrender to or are constrained by corporate dictates as to the exercise of their medical judgment and right to publication of cases in the medical litera ture. A recent case in point involved a Dr. John Zalinsky, a physician at the Brush Beryllium plant outside Cleveland, who had cases of workers suffering from beryllium poisoning and wanted to publish them in a 13 1968 National Safely Congress . medical journal (without mentioning their names, of course). He was told if he did he would have to look for another job. The doctor had a bad heart and was con cerned about looking for other employment. Before he could do anything, he died of a second heart attack. and mines, leaving only 827 inspectors for general safety inspection, construction, safety promotion and education, health, and in dustrial hygiene, according to the Bureau of Labor Statistics. (There are almost twice as man)7 fish and game wardens about 3 000 -- employed by the states to look out for wildlife.) Four states have no safety in Dr. Lorin E. Kerr of the United Mine spection staff in any area and 17 other states Workers Welfare and Retirement Fund, an have 10 or less on their safety inspection authority on coal workers' pneumoconiosis staffs. More shocking is the fact that only (or, as the coal dust disease is popularly three states have staffs specializing in the called, "black lung"), has sharply denounced area of occupational health and industrial "the attitude and influence of employeroriented physicians who avoid facing known facts about the ravages of coal dust in hu man lungs because to do otherwise would cost money. The impact of physician knowl edge and attitudes is apparent in inaccurate or incomplete death certificates. These doc uments are essential for determining the existence of a dangerous dust requiring gov ernmental action for control or eradication. Too often, no records mean no action. Phy sician denial or avoidance of known facts can also determine the publication of infor mation. In 1956, the concern of some physi cians about management attitudes effectively blocked the publication of a paper of mine on coal workers pneumoconiosis in the most widely circulated medical journal in the United States. One can only wonder how many times other medical information vital for the protection of the health of workers has not been published for the same reason. Physician attitudes also influence other groups such as company lawyers, state legis lators, and officials who, all-told, are remark ably resistant to the elimination or control of coal dust because it would cost money." Coal workers' black lung or pneumoconi hygiene. 4. By and large, union leaders have been far too pliable when confronted by manage ment's inaction or decisions regarding worker health and safety. Too often, health and safety conditions are treated as trade-offs for more tangible union gains in wages at the collective bargaining table. This has been the case, for example, with the United Mine Workers leadership, which finally is becoming slightly aroused over the plight of their workers but little dedicated to over turning coal management's modus operandi that treats coal miners as being less expen sive than coal. Union leaders simply do not give health and safety a first rank pri ority; their lack of aggressive lobbying for the proposed Occupational Safety and Health Act of 1968 in Congress cannot be covered up by resolutions and resonant statements for the records. Labor leaders are wanted on the ramparts, not just on the lecord. 5. The Federal government has abdicated its responsibility to devote funds toward effective research programs and training programs for occupational health and safety. The Department of Health, Education, and Welfare (H EW ) has had no sense of the osis affects at least 150,000 active and retired importance of this problem, the need to de miners in advanced stages of lung destruc velop preventive systems and competent med tion. Two thousand men die from this dis ical and engineering personnel. H EW 's ad ease in Pennsylvania every year.

State safety laws and regulations are weak, inspection is poor, and penalties rarely imposed. The states spend an average of 40 cents per worker per year on industrial safety. Some states such as Texas and Oklahoma have taken this down to two cents per worker per year. Of the 1,524 state inspectors, 697 inspect boilers, elevators consistent funding--$5 million since 19o3 for research on the causes and prevention of coal workers' pneumoconiosis has had little to show for it, apart from a prevalence study com pleted three years ago. It is dis maying to note that not only does Western Europe spend twenty times the level on re search in the coal dust disease area, but 14 Labor Sessions control measures are years ahead of this country, which does not even have coal dust standards in force. 6. The workmen's compensation system in this country--its coverage, benefits, and de terrence--is creaking with obsolescence. A thorough inquiry is needed and serious thought should be given to uniformity. Not only are there irrational or politically in spired differences between states but some states are still mired in a value system of a bygone age. For example, coal miners' black lung disease is not considered workrelated by the compensation laws of all states, except Pennsylvania (1965), Virginia (1968), and Alabama. Such human derelicts, spitting up coal dust, struggling for breath, afflicted with emphysema, massive fibrosis, or enlarged heart, are denied workmen's compensation in such states as West Vir ginia, Kentucky, Ohio, and Illinois. In Ken tucky, according to the state's Department of Labor, about 1,400 out of 2,000 mines licensed to do business do not comply with the workmen's compensation law for other mine injuries apart from black lung. Yet, the present governor .and his predecessor have not considered law and order to be applicable to coal operators. . Where does this leave the National Safety Council ? Certainly, it does no service to truth and candor to hide the fact that the Council's industrial members and constitu ency take a strong interest in how far the Council goes in the occupational health and safety area. That interest, _to use a mild word, resulted in the Council s being placed in a difficult position regarding the Occupa tional Safety and Health Act of 1968. Some observers believed that the Council retracted from a relatively positive position on the bill in February to a statement more in consonance with industry's preferences a few months later. For the Council, it is the same old dilemma of "to be or not to be" that has plagued its potential independence in other safety areas. If the Council is to be true to its . potential in occupational health and safety, it cannot ignore at least some of the above-noted problems obstructing progress toward more humane working conditions. LASER BEAM PRECAUTIONS By WILLIAM McCULLOUGH Collective Agreement & Grievance Officer, Canadian Union of Public Employees, Ontario Hydro Employees Local 1000, CLC, Toronto, Ont. Before we consider the hazards and pre cautions for the safe use of the laser beam, we should understand what it is. The name laser is an acronym for light amplification by stimulated emission of radiation. The original concept was invented by Dr. Townes in 1955. In 1958 Dr, Townes and Dr. Arthur Schawlou gave a paper on how to construct an optical maser. The name maser is an acronym for micro-wave amplification by stimulated emission of radiation. An optical maser is a laser. _ In 1960 Dr. Theodore Maiman, a scientist then working with the Hughes Aircraft Company, gave the world's first demonstra tion of a laser beam. In 1964 Dr. Townes won the Nobel prize for his work on the theory of lasers. _ The light that comes from a conventional light source radiates in all directions in waves of varying lengths that reinforce or cancel each other. Because it is non-direc tional and of varying wavelengths, it is said to be incoherent. Light from a laser beam travels in only one direction and is all at the same wavelength, so that it reinforces itself and is known as coherent light. Be cause it travels in one direction in straight lines, it is a very narrow beam. _ To obtain a directional beam from an in coherent conventional source of light it must be focused, and even then it soon spreads it's beam again. Ordinary light sources are usually heat units such as incandescent lamps, arc lights, etc. In a neon tube the glass walls remain cool but the electrons activate the neon atoms within the glass tube and ac celerate them to levels normally found at high temperatures. The atoms of the source material are brought to a continuous excited state and they fall back to normal by losing energy through heat and visible light. 15 NATIONAL SAFETY CONGRESS TRANSACTIONS Mining Iridvstry down'the shaft to the'other two levels, kill ing 52 men. It was then described as the worst mining disaster in U.S. history and lo my knowledge, it is still so regarded. Briefly, here are some of the facts : of the 52 killed, 34 lived within the limits of one small city. Forty were married. Three pairs of brothers and three father and son teams were among the victims. The oldest victim was 66; the youngest, 18. Survivors included 107 children under the age of 16-- three men left seven children each. One man survived, climbing 800 feet in 10 minutes. The elected county mine inspector was in the mine at the time and was one of the casualties. Only 10 bodies were recovered. The maximum w o rk m en 's compensation benefit at that time was $14 per week pay able for a maximum of 300 weeks. The operating company was generally re garded as one1of the pioneers in mine safety. The state mining engineer said, "The mine had not been under suspicion as dangerous." The state geologist described mine condi tions as excellent and said, "Every possible precaution had been taken." All of the community's limited resources were mustered to alleviate the hardships-- nurses and clergymen banded together to visit and comfort the survivors, and mer chants helped with donations of food and clothing. The co m p an y --self-insured for workmen's compensation -- voluntarily in cluded the. survivors of the mine inspector, who was not an employee, on their com pensation payroll. The Red Cross withdrew' from the scene, saying the situation was so well handled that anything they might do would be a duplication of effort. The company was cleared of any negli gence, and the U.S. Bureau of Mines report said, "From inspection' and stud}', it is our judgment that the mine was operated ac cording to the best mining practices and that all care possible was taken by the min ing company to safeguard their employees and that the accident was due to causes that could not have been foreseen." I am confident that in the intervening 40 years those of you who are experts in the field have developed new techniques that would make a recurrence of such a disaster highly unlikely, and that you will continue to dedicate yourselves to the prevention of accidents, thereby assuring continued "com munity stability." A SUMMARY OF OCCUPATIONAL HEALTH ASPECTS IN MINING OPERATIONS By ERNEST MASTROMATTEO, M.D., D.P.H., D.I.H. Chief, Occupational Health Service, Environmental Health Branch, Ontario Department of Health, Toronto, Ont., Canada Mining is one of man's most ancient occu pations. It began when man first began to dig for rocks and metals to make tools and weapons. About 20,000 years ago man began to sink shafts and drive tunnels for flint used to make knives, axes, and arrow heads. The Egyptians used copper for metal uten sils, weapons, and ornaments over 15,000 years ago. By 4,000 B.C., copper was in general use throughout Europe. North Amer ican Indians had learned to hammer copper utensils, but they did not learn how to smelt copper. Copper and tin occur together around Cornwall, England; they were smelted to gether to produce bronze for the first time about 2,000 B.C. Bronze daggers and swords dating from this period have been rer.uvi-r<-,l from ancient tombs. Prehistoric man showed llic cfieri-, >f his occupational exposure to flint, lie imdnnbfedly developed silicosis from (linl-knapping --one of the oldest of indus! ries. Egyptian mummies have, been found wilh anlhnicosis and pleural adhesions. The slone cutters for the pyramids must have suffered from severe exposure to silica. Miners have, already been regarded as a breed apart, laving and social conditions described by the early historians were ap palling. The ancient miners were almost al ways slaves, condemned criminals, prisoners 27 1968 National Safety Congress of war, or forced labor. The coal mines in Britain were developed in the twelfth cen tury. Many lives were lost from accidents, black damp, fires, and explosion. In the 16th and 17th centuries the coal mines were greatly expanded with the industrial revolu tion. The industrial revolution brought rapid changes and was followed by awakened so cial concern about w o rk in g co n d itio n s. Women and young children were employed in mines. One of the earliest writers on the health aspects of mining was Georgius Agricola, who published his De Re Metallica in 1556. Agricola discussed in detail the mining, smelting, and refining of gold and silver. He recommended ventilation with fresh air for mine workings. He also recommended the use of masks to protect against mine dusts. Mining operations, because of their diver sity, present a wide variety of occupational exposures, some of which can result in ill health and disability. I hope in this presen tation to touch on many of these exposures, with more particular reference to the min ing industry in Ontario. To some degree, underground work is similar to work done within confined spaces. For this reason, greater attention must be paid tc> toxic substances encountered under ground. The air in mines is more likely to be contaminated than the air in factories. With abnormal conditions, e.g., fires, severe conditions are imposed. Adequate ventila tion and control of air is most important in mines. Pneumoconiosis-Producing Dusts The pneumoconioses still constitute what is perhaps the most difficult as well as the most severe and costly'of .the occupational health problems which the mining industry has to face. Coal Miners' Pneumoconiosis. Coal dust itself has always been considered to be a basically inert dust. In coal mining opera tions, however, it may be inhaled in large amount. The amount of free silica present in the airborne dust is usually quite ^small. Two main types of pneumoconiosis are described: simple pneumoconiosis and prog ressive massive fibrosis (PM F). The former is frequently associated with focal emphy sema, whereas in PM F large solid masses of scar tissue are found in the lung. Tuber culosis is implicated in the majority of cases. Ontario has no coal mining and T have no first hand experience on this subject. A superficial look, however, at the prevalence of coal miners' pneumoconiosis indicates the magnitude of the problem around the world wherever coal is mined. In the United States, a survey of 2,549 Appalachian bituminous coal miners covering the period 1963-1965 disclosed 9.8 per cent with definite x-ray evidence of pneumoconiosis. These miners had spent an average of 29.7 years under ground. Considerable publicity has been given to compensation for coal miners disability in Pennsylvania. The prevalence of pneumoconiosis in coal miners from different countries is demon strated in an I.L.O. report. I have adapted information from this publication in the Table below'.

Miners exposed to mercury, manganese, or soluble lead dusts may develop systemic poisoning. Lead sulphide ores present no real hazard in mining--only in smelting. Miners exposed to manganese dust in both Chile and Cuba have been reported to develop centra] nervous system effects similar to Parkinsonism. No mercury, manganese, or lead mines are found in Ontario. It is per haps worthwhile- to mention that manganese steel is commonly used underground in jaw crushers. A welder in Ontario using an oxyacetylene torch to cut manganese steel under ground developed kidney damage which was attributed to the manganese fumes. Ventila tion in the work area was inadequate. Much of the free world's nickel is mined in Ontario. Dust in nickel mines has not produced occupational health problems apart from occasional cases of dermatitis. Increased risk of nasal sinus cancer and lung cancer has been reported in workers involved in sintering and calcining nickel sulfides. This has not occurred in the mining operations. Increased risk of lung cancer has also been demonstrated in the refining of a cobalt ore containing arsenic. These workers also showed increased incidence of chronic pul monary fibrotic disease. This exposure is still under study. Arsenical dermatitis is common in handling this material and a few cases involving perforation of the nasal septum from arsenic have occurred. Therefore, persons in , an oxygen-deficient atmosphere may be aware of some difficulty, but they are unable to take the appropriate safe action. . The concentration of oxygen in mine air should be maintained above 18 per cent. When the concentration' falls below 16 per cent, symptoms of oxygen lack begin to ap pear. At levels of six per cent or less, col lapse can occur very quickly. Nitrogen, helium, argon, and hydrogen act as simple asphyxiants by excluding oxy gen. Some other gases may be broadly con sidered to be in this category even though they have other physiological actions. These include carbon dioxide, methane, and ethane. The older term "black damp" refers to a mixture of carbon dioxide and nitrogen. Carbon Dioxide. This gas acts as a re spiratory stimulant. Air normally contains about 300 ppm. Workers would not be likely to notice any effect on breathing until the concentration exceeds two per cent in air. Since it causes deeper and faster breath ing, it may enhance the effect of an}' toxic gas present with it, for example, carbon monoxide. Methane. This gas occurs most commonly in coal mines. It is occasionally encountered in_ other mines--iron ore, salt, etc. It is primarily a fire and explosion hazard rather than a health hazard, but can act as an asphyxiant. ' NoxiousGases The word noxious comes from the Latin word injurious. To the industrial hygienist, a noxious substance is one which produces adverse effects on the worker from annoy ance or discomfort to illness or death. Oxygen Lack. Oxygen is the most impor tant constituent for human life. Man can live only a few minutes without oxygen-- his reserve of, stored oxygen in the lungs, blood and tissues is sufficient to last for only four to five minutes once he is deprived of oxygen. Oxygen lack can occur in mines in differ ent ways--:by dilution with simple asphyxi ants seeping out of rock strata, by absorp tion of oxygen into rock strata (this occurs mostly in coal mines), or by consumption in chemical or biological reaction. Oxygen lack can be very insidious in its effects, be cause it causes impairment of judgment. Carbon Monoxide. Carbon monoxide is not a normal constituent of the air. It is produced by combustion sources--fire, ex plosion, or the internal combustion engine. It is produced by blasting agents. Concen trations of 400 to 500 ppm in air may be tolerated for a short time; exposures of 1,500 to 2,000 ppm are dangerous in a short time. I do not feel there is sufficient evi dence to accept the concept of chronic car bon monoxide poisoning from repeated ex posures underground. . Ammonia. Ammonia is o cca sio n a lly encountered underground. It provides ade quate warning of its presence, because of its irritating action. Sulfur Dioxide. This is produced by the reduction of sulfide ores. Blasting in some types of sulfide ores may produce tempo rary high concentrations. It acts primarily as an irritant of the upper respiratory tract, 30 Mining Industry but severe exposure may result in bronchitis may result in two to six days in these severe and occasionally edema of the lungs. It has cases. Chronic changes from arsine exposure been suggested that continued exposure to may also oc-cur. low concentrations of sulfur dioxide could result in chronic respiratory disease; e.g., chronic bronchitis with or without emphy sema. At the present time, a study is under way in a group of smelter workers exposed to sulfur dioxide in Ontario. Their respira tory illness experience will be compared to other groups in the same company not ex posed to this gas. ' Hydrogen Sulfide. Hydrogen sulfide is produced chiefly from the decomposition of organic matter. It may occur in mines where sulfide ores are found. It is soluble in water or oil and it may flow for some distance from its place of origin to escape at some unexpected place. Hydrogen sulfide has a characteristic odor at low concentrations. Its odor cannot be relied upon, however, to give Oxides of Nitrogen (Nitrous Fumes). Of adequate warning of its presence, because these, nitrogen dioxide (N 0 2) is of special in lethal concentrations this gas rapidly para importance. It is produced in diesel exhaust lyzes the sense of smell. Such concentrations and from blasting agents used underground. also affect the respiratory center in the brain The ventilation requirement for diesel en resulting in failure of respiration. I gines used underground is determined by the nitrogen dioxide produced (and the dis agreeable odor of aldehyde). This is one of the most insidious of all gases. It may be inhaled in lethal concentra tions without marked discomfort at the time of exposure. Later, it produces a delayed pulmonary edema. . Air sampling after blasting underground shows peak concentrations occur two to six minutes after the blast, and significant con centrations may remain for about 15 minutes after the blast. Commonly, levels of 200 ppm are produced, but values up to 800 ppm have been reported.after blasting. / . .. _ _ ... Radioactivity --- - " . Radium, a naturally occurring radioactive isotope, is distributed in small amounts in the earth's crust, The radioactive disintegra tion of radium results in radon-222 and radon daughters. The air in underground workings contains some radon from seepage of the gas into mine workings. In most non uranium mines, the concentration of radon does not present any significant exposure; one notable exception is the fluorspar mine in St. Lawrence, Newfoundland. In uranium mines the radon concentration in the mine air is much higher than in other mines. Studies of uranium miners in the Adequate ventilation must be provided to United States have revealed a significant remove nitrogen dioxide and other gases increase in the incidence of lung cancer.

The hazard from radon daughters is measured in Working Levels (W L), One WL is defined as that combination of radon It has been recommended that 75 cfm per daughters in one liter of air that will result horsepower be provided for the control of in an ultimate emission of 1.3 x 105 M eV diesels used underground. of potential alpha-energy. Arsine. Arsine is formed when nascent hydrogen is produced in the presence of arsenic. Acid treatment of arsenical ores may give rise to arsine production. Exposure to arsine results in destruction of red blood cells with anemia. This anemia may develop within a few hours in acute exposures, and in severe cases the anemia is extreme; death In unventilated underground mines, the concentration of. radon daughters may vary from a fraction of a WL to several thousand WL. Presumably, some degree of risk exists at all working levels but the maximum, in crease of lung cancer occurs when the cumu lative exposure exceeds .1,000 working level months (1,000 W LM ), and when the miners 31 1968 National Safety Congress are moderate to heavy .smokers, and when they have worked in the mines 10 vears or more. ' The simplest control measure is to venti ate the mine with fresh- outside air. An other ^ method _of control is to limit the miners time in areas high in radon and . a^ J ller products. In all areas where radon is being emanated, the ventilation rate should dark locations. Such levels of illumination likely contribute to accidents underground. No reports of nystagmus, common in British coal miners in Wales, have appeared in On tario. Miner's nystagmus is related to poor levels of illumination, but there appears to be an emotional overlay. Vibration provide one complete air change every four minutes unless radon daughters have been shown to be low.

I am not aware of anv cases occurring in Ontario hard rock miners using pneumatic drills. It was my impression that the vibration frequency and the amplitude was not in the same range as that of the aluminum chipping guns. It is of interest, however, to note that cases have been re ported m uranium miners in Saskatchewan who used a smaller "jack-leg" drill. An im portant factor in these cases is the cold ambient temperature in the area where these men worked. Noise E xplosives Noise in mining operations deserves special comment in its own right. Drilling and underground crushing almost always create excessive noise levels requiring a good Hearing conservation program, involving pre employment and periodic audiograms plus the wearing of hearing protection for all workers m high noise areas. Heat Some occupational health aspects involv ing explosives have been touched on in dis cussing the various gases which might be encountered in mining.

Miners often work in semi- 32 the past. This has been controlled. Occa sionally, there are isolated cases of derma titis. From time to time, questions are raised concerning oil mist exposure, particularly in ruling overhead holes. From the occupational health point of View, A N /FO mixture does not present any greater hazard than the use of conventional explosives. In Ontario, a number of deaths have oc- .

Handling; methods to minimize dust. 3. Ventilation. Local ventilation should be used where possible at the point where contaminants are generated. General ventila tion with provision of fresh air to maintain Synthetic Resins Various synthetic resins have been intro duced into mining applications for special purposes; e.g., grouting and sealing, and rock bolting. Epoxy and polyester resins are used in rock bolting. The use of epoxy resins may result in cases of respiratory irritation and dermatitis from the hardeners used. Derma titis is occasionally encountered with' the polyester used. Polyurethane has been used in mines as a seal. These contain isocyanates (MDI or T D I). Of these, MDI is less volatile and less likely to give trouble. Both of these isocyanates, however, may give rise to bron chial irritation or allergic bronchitis with asthmatic-like symptoms.

The thresh old limit values should be used as guides to arrive at reasonable control measures.
