The first objective was reached by show ing the film. The Eyes Have It, a well as making posters of all the Eyes Saved stories. Plus the fact that the committee members went back into their divisions and preached eye safety. The second objective was reached by re- ' viewing with the committee all of the foot injuries which could have been prevented had safety shoes been worn. Armed with this information, each of the representatives went back to their divisions and started to keep a record of the number of employees wearing safety shoes, and the reasons why the others were not wearing them. This par ticular type of promotion decreased our foot and toe injuries from an average of 18 per month for a nine-month period to three per month over a seven-month period. The third objective was attained when the management sponsored a hobby show. The safety committee planned a booth in which we displayed the drop ball test for safety | lenses, a homemade safety shoe testing de- ' vice using an oscillograph to record the foot pounds of energy delivery on the safety toe, displayed pictures of all of our "eyes and feet" saved, as well as all of the personal and protective equipment which was avail-, able in our Safety Store. This booth was a tremendous success. Conclusion: This program worked so suc cessfully that our management has adopted it as the standard method of training super visors. Our methods program is now under way and supervisors are scheduled to spend one week with the methods department usu ally doing the work. A short time back, supervisors were scheduled into the stand ards department the. same way. We find the best training method7 is in letting the trainee actually do the work instead of listening. Whenever we need a so-called "shot in the arm." we use this training method on our top management, and believe me it blos soms out with the desired results. Job Training at the Butte Mines of the Anaconda Copper Mining Company -\ By L. F. BISHOP Research Eng., Anaconda Copper Mining Co.. Butte, Mont. When a mining operation is faced with a shortage of underground miners the ob vious first choice is to try to obtain more miners. If this is not possible the remaining choice, is to obtain the manpower-available and by training to develop this manpower into a competent group of miners. The training of this group will , have a three-fold objective: safety, quality,- time; the men must be trained in the shortest time possible to do quality work with safety. Therefore, the training must be organized to accomplish this end with as little lost motion as possible. The training methods of the Anaconda Copper Mining Company at Butte are organized with this objective. A primary step in training a man in this work is to find out what he already knows. This is done at the Butte Mines Employ- meriPBureau. Here, the prospective miner is interviewed. If he has a previous employ ment record in Butte, his record will im mediately indicate his capabilities and be is gfveo-a permit to apply for a mining job at f any .one of the mines. If-be is a.newcomer. \Jtc is interviewed carefully as to his experieribe-in)mining or related work in other district^.' If he is'a "green" than he will be referred to a mine foreman for training in a "Student Slope." , The student stopes are actual producing slopes in which student miners leam by do ing safely all the fundamental operations in connection with sloping. They do the various jobs necessary to the process! of excavation, timbering, handling ore, and filling,Ju a two or three man stope under the guidance of a shiftboss or instructor.

In the other cases the falls occurred in places where there had bees no obvious indication that bad roof was developing. Apparently, with little or no previous indication of. weakness, the roof can develop a condition rapidly that may cause it to falL Although none of the roof failures caused an injury, we realize that any such condition, is a potential hazard, and this stresses the need for frequent and careful roof inspec. don. It also points out the need for con' tinned study of the subject of roof bolting, that we may be better able to anticipate a dangerous condition. Our workmen are being taught to look' for and to recognize the signs that usually precede such failures, so that they may find a bad condition early, protect themselves against the danger and call it to the atten tion of a supervisor. In an effort to control roof conditions that possibly could develop into a failure, we intend to use 44 inch bolts in the head ings instead of 32 inches, continue to sup plement the bolts with wooden posts tinder wet or damaged roof, as described pre viously, and consider various modifications of other mining practices, such as width of entry and location of loading points. Roof support costs, as a result of roof bolting, have increased more than 100 per cent, but the advantages that have resulted otherwise have more than justified the cost. .These advantages include the following: More assured control of roof. Little /frtimhenhg cost Increised' tons of ore loaded per man day Less contamination of loose ore. Lowered haulage cost per ton. . Lofrcrcd preparation cost.. Improyed^dearance on haulages.. Easelof moving loading equipment / Availability of bolts for support of electric cables, snatch blocks, etc. In short the operation is safer more eco nomical and more efficient In four years only two accidents have occurred in connection with roof bolting. A single roof-fall injury occurred when a helper was struck- by a falling piece of loose roof he had failed to observe and pull down, and a rbof-boltmg'.sfbper :operator sustained an injury when he took bold of a revolving drill steel, loosely, to 'steady it while collaring a hole. The steel broke as he held it, causing his hand, to be squeezed between the stoper and the roof. The driller should have hern holding the drill instead of the drill steel. Our experience has led us to believe that when a roof-bolting program is evolved that is suitable to local conditions, the safety and efficiency of an operation is improved. We fed that the bolting has been applied in a logical manner to the conditions existing at Rnffner Mine, and although we.have .ex perienced some failures, satisfactory results have .been obtained. . . 1 Rock Bolt Developments in Butte Mmes t By V.

DOOLING Safety Dir,, Hood Rubber Dir., The B. F."Goodrich Co., Watertown, Mass.; Chairman. Statistical Committee J When injury rates are compiled in ac cordance with the standard method, they can contribute immeasurably to the success of safety work in many ways. The princi pal quality of such rates is that they*'can 1c compared one with another, a procedure which is important in measuring safety per-, formance. One rate, men though compiled in accordance with the standard method, contributes little helpful information. For example, if a company had a frequency rate of. 15.0, this still docs not tell too much about the company's safety performance. True, it indicates the current rate at which disabling injuries arc occurring, but it does not indicate whether that rate is good or lad, or whether it is getting better or worse. However, if injury rates are available for other companies doing. similar v.crk, the rate of 15.0 assumes significance by con- ;arisen. And, if trie previous year's rate for the company is available, or the rates for several previous years, then the rate of 15.0 assumes added significance by identifying the trend of injury experience. m Records of accidents are just as funda mental to efficient control of accidents as control over men, equipment and materials are for the efficiency in the operation of an industrial organization. Interest in safety is created among su pervisors when they are furnished wit'ryiniurination about the injury records which are guidecosts to them. Decreasing rates show that the safety program is producing results, while increasing rates indicate that {something is wrong and requires investiga tion. .Accident records help to determine the major accident problems so that efforts may be directed where the largest reductions in injuries may be expected. Statistics are also valuable for providing supervisors and safety committees with in formation about the most frequent.-unsafe practices and conditions so that they can utilize their time and efforts to the greatest advantage. During the year 1952 there were 153 con cerns in the Rubber Section Safety Contest. These contestants were divided into five Divisions in accordance with the average man-hours worked per month. The Divi sions were as follows: Division Average Monthly Min Hours Division I ........................... . (Over 400.000) Division II ..........................

CO Three types of ^awards for outstanding performance in industrial accident preven tion arc provided for in the "Plan for Rec ognizing Good Industrial Safety Records" adopted in January 1952 by the Industrial Conference and the Board of Directors of the National Safetv Council. lhe three types of awards are: 1. The Award of Honor, the highest award, replaces the Distinguished Service "to Safety Award. It goes to industrial estab lishments whose experience meets rigorous statistical standards, even though it may not be injury-tree. It also goes to those which complete 3.CC0.000 man-hours without a dis abling injury. 2. The Award of Merit has similar but less exacting requirements. The standards for non-perfect records are somewhat lower, "and the minimum number of injur- free man hours needed to qualify is 1,000,000. 3. The Certificate of Commendation is given only for no injury records covering a . period of er.e or more entire calendar years red involving exposure of 200,000 -to 1.000,- For qualifying calendar-year experience, all three types of awards arc made auto matically on the basis of annual reports snbmitted to the Council by members. The Award of Honor and the Award of Merit may also be made on special application in two types of cases: 1. Where a qualifying total of injury free man-hours is accumulated in some'pe riod other than a calendar year. 2. Where a current period of" two or more years is to be used in evaluating in jury rate improvement. Eight plants qualified for the Award o: Honor, which is six percent of those re porting. This is considerably more than the corresponding percentage of 3.6 for all in dustries. Two of these Honor winners were for perfect records and six were on a parcomparison basis. The names of the two companies that had perfect records arc as follows: Firestone Tire and Rubber Company Akron Plant #2. Goodyear Tire and Rubber Ccntp.tnv. England Plant. The other six winners o: the Award of Honor on a par-comparison ' r.v following: The B. F. Goodrich Co., Tuscaloosa, AlaPlant. Hood Rubber Company, a Division of the 3. F. Goodrich Company, Watertown, Mass. Goodyear -Tire and Rubber Company. Gadsen, Ala. Firestone Tire and Rubber Company, En tire Company. Fircstcne Tire and Rubber Company, Memphis Plant. Firestone Tire and Rubber Company, All Akron .Plants. Perhaps a Word of explanation is neces sary about the two awards to ail Firestone Akron plants and to their,d-AKron Plant No. 2. The award to all Akron p:ar."? was a par-comparison-''award based.. o experience for the calendar year 1952. The award to Akron Plant No. 2 was for a no-injury period terminating in 1953. only a ccurle of months before this study v.-as undertaken. There were 21 Awards of Merit, tvei'-e for perfect records, and nine on the 'T.rccmparir-on. For all industries, the percent- Rubber industry Sofe!y'Dcta, 1952, ,-lzeerds end Results--1952 Trends a six per cent, which, on 150 units, would figure to about eight awards. There were four Certificates of Commen dation for 1952. The theoretical number based on the all-industry percentage would have been four or five. It might be of interest to know how the average frequency rates compare for the first six months of 1953 with the total av erage of each Division for 1952: Yeir 1933 All Divisions . ...

According to statistics from Accident reels (I would like to recommend its use and it should be-read by all companies). reveals that the Rubber industry stands in Hhh-place for both Frequency and Severity Rates, and well above the standing o; ail industries, a performance we all can take pride in.

Of course, in some cases neither of these devices prevent the man from being caught but they both have such a fast and automatic response, that they will protect against a serious injury. _,Wc arc now working cn an electric eye model that will provide a light l>cam and eye-that will follow the danger side of the bite area during buildup. This model will stop the calendar if a hand gets in the danger area, and thus will prevent the accident. A few words about the engineer's assist ance in a safety program might be in order. Many of our windup safety projects have been difficult merely becau.se of the peculiar mechanics of the machine. This applies mainly to old machines with high inertia drives, which makes quick stopping difficult, or, to old handwheel clutches that require turning of the handwheel to stop the windup. Some of these hazards have existed for many years because r.o one had an economical f sc'ution. An engineer with a good imagination can ; usually find a simple solution to these pro's- ; Ians. We have recently solved a number of ^ knotty problems of long standing by simply jij inserting an air cylinder and piston in series 'i with an operating bar or shipper rod. A cable operated valve instantly reverses the :jj action of the piston and retracts'the bar. which quickly stops the machine until '.he y valve is reset by Irani Failure of sir pres- A sure will also render the machine inoperable, y Mv final admonition to the saietv engineer -s is to take an electronic engineer and a me- j-5 chr.nicn! engineer to the? problem job and examine the machine from ail angles. Let / them know that you and their feiiowmen h are depending cn them to., save their limbs, lives and loved ones, and 'you can rest as sured that your confidence in them will bring rich rewards of safer machines.

No--because clergymen arc never near such equipment. 3. Accordingly, the most effective way to avoid accidents is to keep everyone away from critical rolls and "pinch points." : C. This can be accomplished by the fol lowing methods of minimizing' exposure' to accidents and specific illustrations will be shewn later. Methods of Minimizing Zrpesure to Accidents 1.

Dt-a.v, Safety Dir., The Firestone Tire and'Rubber Cc., 1-lcm- phis, Term. The subject of continuous run-buttons is being brought up. It is one of the extreme hazards .in the rubber industry-. Titesc con tinuous run-buttom are those on the semi automatic- machines, :iot on the automatic machines. A3 a man was-gumboring the tie he got pulled .into the machine. What can be done to eliminate this particular feature of the operation ? It has been suggested by Mr. Cross of Firestone to continue with the old foot pedal A moving foot pedal is Wi ;es:ed so that ihc/mnn ,, ~d r-ti:I bcdctr.tr torre v,';iert he tiikcs ni5 roc*. on the pedal, the r/.nchire stops. It was pointed cut that a safety was put under some of the heavy duty machines to eliminate the possibility of the man getting pulled by the drum. Spinner Bars This is a bar that puts on plies on. a big tire building machine. One points out that they blow them on with air. This brings up a number;'oF hazards, also. The bar is attached immediately in a scries 0: short roilcrs. The bar is operated by a spring being attached to the machine and the man docs not have to hold it and make it pos sible for the bar to fly bad-: and hit him. Cr.a of the U. S. Plants puts a tread cn this which is already spliced and this can cause considerable trouble with the bar fly ing cad< ar.d hitting the man in the head. `Other companies just run the trend on by a continuous-run method. There is r.o standard way of putting on treads or using roller bars or putting 0:1 plies. It seems that there wns "o dim: solution as to hew to eliminate he.mar. workirg with a prouder bar or h.rcller her ether than 'constant supervision, very thorough training and follow up work on safety in struction. (B. F. Goodrich is talking about a bar which looks something like a crank, similar to that of a arodder bar.

There m: a discussicn as -to vrhat lord ci ncddcr.t problems sri^being caused 'cry iL Mr. Lynch of Firestone described ccc cf the types of accidents he was having. One of "he points brought up was that one c: the- operators of the Bagomatic machines would lay the tire in cr.e mold; then go over and lay a tire in another mold, then come cuds, as the machine was gc-ir.g down cn the hrst mold, to lay the serial. This created ar. extreme hazard. This deflnitely calls fer a trarrreg pro gram and should be eliminated. The oper ator should lay the tire in cr.e mod and lay the serial and then push the butte*' to close the mold. On the Bagomatics. when the meld nr* > in process ar.d the safetv was hit. the mold Xczo Problems in the Tire Riant (Round Tabic Discussion.) would go back up r.o matter where the safety v. hit. A new installation was put in whereby when the safety was hit, the mold would immediately step and [the lid would !/: continue to reverse itself and so back * Mr. Turner of Goodyear pointed out that when the bag is about to blow in a mcid, they put in a strain safety so they-will know when the bag is going to blow. This would stop the mold from opening. Knowing that there was still pressure in tiie bag, it was .i.mgerous to open the mold because the bag would continue to blow.. A safety installa tion was put on a post several feet away : rom the mold which was a remote switch; when the operator was called away from the r.told, this switch was used to open the mold in order to get the tire cut. The bag would i '.or.v. Since no one was close to the mold, no * -:Vc Would get hurt. Mr. Croushorc of Armstrong has some :tcw Bngomatic machines. He doesn't have any particular trouble with them. He pointed out that the new type of installation where the bottom haif of the mold is at floor lea-el -.veuid make a much easier handling problem. Mr. Frame of Goodyear asked a question < n ::cw to prevent accidents.-when nobis and housings on the melds break. The .-only cifety that he has cn it is a safety block. It -w.s pointed-out that the new McXcil molds are counterweigh*,ed ro the molds cannot tali. On the old type which he is speaking of. the mold can drop cut of the top haif of the mold. When the transmission housing breaks, lie mcid will roll and drop. He wants to know what safety devices can be used. He uses a safety bice:: winch allows a man enough time to get cut of the mold before ;he top falls. Mr. Cross of Firestone pointed out .the way the safeties at the Firestone-plant work: MT.cn the mold opens entirely,-'a pipe-type safety falls in line over the cylinder which holds the molds up and the man has to pull a lever to dose the mold when he wants to shut the mold. man from Toronto pointed c i safetv cn the back .of the mold which was a form of notches. When ti-.e meld would drop the safety would i -n into the notch, eliminating the possibility o: .he mold continuing to tali. Getting ute employee to use the safeiy Slock is important. It is a matter of con tinuous supervision, continuous safety in structions, and pointing cut the importance of the safety features to be used. Mr. Kumpel of the union felt that it should be a rule that every man should be required to use this block for his own pro tection, that it should even be put into nego tiations. Mr. Carson of U. S. Rubber wanted to know what methods other plants were fol lowing for deaning the molds. Severai of the plants make minor repairs and also dean the mold while the mold is in the jacket. The mold has a safety lock and a red tag is put on the switch before clean ing of the mold is started. No deaning operator gets into a mold until it is certain that the safeties are locked in pb.ee, with the result that the mold can be effectively and safely deaned by leaving the mold in the jacket. T. would be quite an item to be required to take the mold out of the jacket every time it needed cleaning. It is suggested that all manufacturers check with the McNeil mold manufacturer to see if they can work out some uniform safety that ccuid be used which would be effective while making minor repairs and cleaning the mold. Font Cementing After material has gene through the cal ender and then is spread with a pest cement, there ib considerable fire and explosive haz ard. Much has been done. Further discussion was requested cn preventive measures to eliminate the possibility of serious injury. An accident occurred several years ago where the fans stopped in a particular post cementing unit. The fabric continued to be dipped and it accumulated considerable fumes close to the fabric. WT.cn an employee came up to touch the fabric, a static spark caused a fira This has been corrected so that when the fans in the unit stop that is, the venti lating unit, this automatically, stops die whole calender unit. There has been a very strict regulation in installation of these particular units in that they arc all approved and authorized by the insurance companies md everything is in accordance with tk rating the possibility of an .ecp'o: or . Era There are also automatic cn nguishers in these units so that there dc-rsn : erven have to be a fire, but a certain temper ature wiil set off these Ere extinguishing urn. 17 -\ r* * vIa V~w*`W*\*W*s*W~aypOf? nU4^i*: f*o*^5 -o (Round Tabic Ddecucsicn) i'rcsicir.g: X.

You should r.ot be able to open tljis door until all steam pres sure is out of the vessel. goods. Ir. answer to the question of iiow to guard Mr. Dochag brought up the problem of multiple deck presses sticking and how the men can be prevented from jumping the gun in going into these presses to unload, not realizing that the top deck has stuck ciosed, and it would tali on to the operator's hands. Another problem brought up was in rciahon to lifting, referring to manual opera tions, how the men may be instructed, the controls, and various laws that are in effect hr drtterent states concerning the load w'nich a mat: or a woman A allowed to lift. Other problems posed included monorail svstems in tubing divisions and what could !-j dune to prevent head injuries and gettmg the proper head clearance.. Another problem discussed was back strains, hernias, and the 'ike. that occur in the press rows. The type c; man that should be hired to do the job as far as physical punk heations are concerned. Still another problem had to deal with punch presses and prevent accidents when trimming small molded goods, there were a great many comments made by a number c: the members at this committee meeting which could be generalized in the following words: that you should, wherever possible, so design and guard your machine that it wouid not be able to repeat, even if it smashed the machine rather than repeating. A guard should be used, wherever possible, that comes closed before- the press actuates. Wherever possible,, it is practical to use a double switch where the operator must leave lth hands on the buttons before the press would actuate or close. It was also suggested that the real solu tion to this problem is going to come when we car. sc design cur punch presses, dies, and like machine--' so that the operator will r.ot hare to place this hard between the dies in positioning the piece which, is being trimmed. hoists being used it; press rows and molded In answer to the cucstion by Mr. Dc-eling goods plants and how they should be in of what could he dene to prevent uiuhi'ce spected and what can "'C done to prevent deck presses sticking, the top deck falling induces. and crushing the hand of the press operator. Another question brought up was late reporting of accidents which developed into infection cases. The last one was that of people who were injured by simpiy trying to work too fast in order that they may heat due rates in effect. Mr. Pomeroy suggested a solution which i? iveir.g used at the Ohio Rubber. He offered to send prints and photographs of the cur tain widen the engineers designed and which we feel will do away wit!; this particular hazard. In answer to the question erttru.-ion The last question which we had time to and vulcanizers, Stanley Wright described -- discuss was the problem c: inspection, of the accident which occurred in Inland Rub- heists in the press box. Mr. Longer ex her and the measures which were taken to prevent a recurrence of an accident similar to that.
