IS Safety Supermarket Each fall, some 12,000 safety experts from all over the U.S. and many foreign countries gather m Chicago to discuss safe attitudes, methods and equipment. It isn't just a gossip session. There's serious thought and talk on how to prevail the tragic accidents-- on the job, off the job, in the home, on the streets and highways-- which claim about 95.000 lives every year. Each edition of the Transactions is a handy reference to the up-tothe-minute ideas and experiences of these top men in all fields of accident prevention. Safety people everywhere hare found in the Congress Transanions much useful ammunition to aid them in the war on accidents. The National Safetj' Congress Transactions are published in volumes, each covering a phase of the safety picture, along with a General Session* and Detailed Index to all volumes. The volumes of the 1056 Congress Transactions are listed on the last page of this volume. In preparing these Transactions, the proceedings of the Congress have been condensed and edited for reference purposes. Complete original manuscripts, with any charts or illustrations which were used, are available in National Safety Council files. Views expressed at the Congress or in this record are those of the Congress participants and arc not necessarily those of the National Safety Council- AUTOMOTIVE & MACHINE SHOP SECTION POWER PRESS AND FORGING SECTION Thi> volume is a record oi the sessions held at the 1956 National Safety Congress by the Automotive and Machine Shop Section and Power Press and Forging Section. The conduct of these Congress sessions each year is only one of the many cooperative activities which the Automotive and Machine Sltop Section and Power Press and Forging Section entry on in behalf of their members, and for the benefit of accident prevention work in automotive and machine shops and power press and forging operation*. These Sections give guidance in the preparation of a great variety of technical and educational material useful in the day-to-day safely programs of plants operating automotive and machine shops and power presses. The activities of these Sections are under the direction of their Executive Committees, the members of which arc listed at the close of tins volume. 6 1956 National Safety Congress white lead, and using; a xylol vehicle, were sprayed on metal panels then moved through banks of infra-red tights with natural ven tilation only. The fumes from the infra-red oven were rising and moving into the upper area oS one end of a large bay. The work in this portion of the bay necessitated the use of a crane and operator for extended periods. The crane operator was affected by headadies, loss of appitite, plus the problem of poor and sometimes dangerous crane opera tions. Since you undoubtedly have formulated an answer for this problem and know the results, this will merely be a continuation of your solution. A large blower, pending more adequate control ventilation was placed near the top of die infra-red oven and the contaminants moved out of the building. Result-- Xo more ill health and a safer crane operation. CASE 2. High noise levels were being caused by the air noise from an air hoist. The overall noise level was 114 decibels. A muffler was installed on the air release of the hoist and the noise level dropped down to 87 decibels, or a reduction in noise level of 27 decibels, which is in noise talk a whale of a reduction and in this case eco nomical. CASE 3. A crane operator was being affected by vapors from a fluoride salt being dumped into a steel ladle containing mpltrp steel. This was solved rather ingenuously by dunging the sue and shape of the fluoride salt crystals. At any rate, there were no more complaints iron the crane operators. There is no end to the number of success ful source control cases ha* could be cited, However, it is not always possible to con trol the hazard at its source so the next best thing to do it to supply protection to the employees who mar be affected by the hazard. Such was the case of the crane operator over a soaking pit operation in a steel mill. The temperature of the soaking pit was Z200F. The steel in the pit was removed by the crane and placed on a conveyor. Some infra-red heat was radiated and when this infra-red was considered, temperatures ranging upward to 140F. were found m the crane cabs. A new crane cab was designed having double glass walls, insulated floors and ceil ing and covered on the outside by alumi nized paint. An air conditioned unit sup plied air to the inside of the cab at the rate of 720 cubic feet per minute with a velocity through the grill inlet oi 300 fee: per minute. After this crane was placed in operation the crane cab temperature ranged from 86 to 90F. Quite a reduction from I40F. maxi mum to a 9QF. maximum with a subsequent drop in heat fatigue. Briefly, there is a second phase of ind:t-trial health at high plant levels. In machine shops, and other metal pro cessing industries, you will find solvents ot all kinds, some much more toxic than others; you will find plastic resins and their catytists, new cooling and new coating ma terials are common place. The supplier, for the-most part, recog nizes the haards oi these materials and issues instructions designed to minimize or eliminate the danger of injury from lire use os his product. We have been asked fn many plants to determine the source of health injuries and in the course of our surveys, would find that the cause of the injuries were due to violations of the in structions from the supplier. In many of the instances, the safety engineer had not been informed of the presence of the offending material Based on field experience, you. as a safety engineer, should continue to ask yourseli these questions: 1. Do I have a knowledge of the mate rials bring used in my plant? 2. Have l checked the list of materials recently to see if new ones have been added? 3. Have I checked my plant to see if new toxic materials are being used that have not been called to the atten tion of the safety department ? . 4. Are the toxic materials in my plant being used in accordance with the sup pliers instructions or as prescribed by Industrial Hygiene personnel ? If you can answer these questions in the affirmatives you have eliminated a sizeable number of your industrial health problems. You will also find that in this caw your overhead will be coming down which is my way of thinking is Industrial Health at a high plant level. ' Joint Meeting with the Power Press and Forging Section 7 Machining Metal with Safety By WILLIAM A. ISAACSON Divisional Safety Supvr., Stamping Div., Tank Plant, Chrysler Corp-, Detroit, Mich. What docs metal machining mean fo ycur Metal machining can he defined as an opera?i.i r.r operations, performed roost com:u.Iy by machine tools, in which metal is .old worked by progressively removing metal in the form of chips. Injuries that result item the operation oi these machine tools most often result from unsafe practices or because of incorrect j.rocednrcs which are basically problems of training and supervision. In general, the three causes of accidmts and injuries are unsafe practices, unsafe conditions, and un-aie altitudes. Before going into the methods of acci dent prevention on machine tools, we should tir-t explain some oi the different types of .,}*rations and some of the most common *uu>cs of accidents on each. The Xational Association of Machine Tool Builders has .-lissified some two hundred types of ma,-hine tods into five basic groups: 1. Milling II. Turning III. riamng IV. Grinding V. Boring Milling Machines Milling consists of machining a |*iece of metal by bringing it into contact with a ro uting cutter with multiple cutting edges. `Hie work is held on a table and fed past or into the cutter. Statistics reveal that milling operations are generally low in accident frequency, but high in severity. About two thirds of tlic milling machine accidents occur when opera tor. are unloading or attempt to make ad justments. Other causes of injuries exper ienced with use of this type of machinery include: 1. Measuring or calipering the work when the machine is operating. Z Using a rag to clean excess oil on the table while the cutter is turning. 3. Wearing gloves, tics or loose clothing. 4. Failure to draw' the job back to a safe - distance when loading or unloading. 5. Adjusting the coolant flow while cutter is turning. 6. C*ing a jig or vise which prevents close adjustment of the guard. 7. Failure to clamp the work securely. ft. leaving hand tools on the work table. Turning Machines Turning ouuists of shaping a rotating piece by means of a cutting tool, which is mounted on a carriage that provides infeed ur cross-feed of the tool. Work is com monly rotated between centers or while held by a chuck, face plate; or fixture. Some of the most common causes of in juries resulting from this type of.operation :: 1. Using calipers or gauge on the work while the machine is in operation. 2. Using the hand instead of a stidt to hold emery doth against the work ot filing the rotating piece right-handed. X Flying metal chips or attempting to clean chips when machine is in opera tion. 4. Contact with projections on face plates, chucks, or lathe dogs. 5. Hand braking of machine. Planing Machines Planing ojratkms are primarily intended jnr machining flat surfaces but can be ar ranged for machining many kinds of ctirvnl. rJd. or irregular surfaces also. Shapers although generally classified aplaning machines, differ slightly from the jrianer machines in that the work is fastened into a vise or fixture and the cutting tool is passed back and fourth over the work. 8 3956 National Safety Congress Planers work on the same principal, except the cutting tool is held stationary and the work is mounted on a reciprocating table which passes aider the tool or tools. Other machine tools coming within this classification are slotters and broaches. The most frequent causes of planer acddots appear lo result from inadequate train* mg and supervision. They are: 1. The exposure of the hand or fingers between the tool and the metal being machined. 2. Allowing the hand to come is contact ' with sharp edges. 3. Obtaining measurements while the ma chine is in operation. A. Failure to secure tool or damp work prior to starting operation. 5. Riding the job. 6. Having msufiociem clearance for the work. - 7. Coming in contact with reversing dogs. 8. Failure on die part of the operator to insure that the current is turned on a magnetic chuck prior to operating. Broach operations may be safeguarded during normal operations by the use oi sup* plementary controls. The most widely used safeguard for broaches is a standard twohand constant pressure control. Also, an emergency shut-off device should be installed for the convenience of the operator. Grinding Machines A grinding machine utilizes an abrasive wheel revolving at high speed to cut a piece of metal The process may be internal grinding, external cylindrical grinding, or surface grinding, and includes such methods as polishing; buffing, and hotting. The abrasive grinding wheel is probably the most universally used power tod in all industry. Because of the wide and common usafe of abrasive wheels and their frequent use under conditions where safety-minded supervision is lacking frequent injuries re sult.from tins operation. Some of the causes of injuries on abrasive wheels include: 1. Failure to use personal eye protection equipment. 2. Cleaning, adjusting or gauging work while the machine is in motion. 3. Wheels or transmission parts not prop erly guarded. 4. Applying wheel too quickly or taking too large a cut. 5. Excessive wheel speed or bursting of wheels-. 6. Holding the work improperly or too high above wheel center line. 7. Requiring operator to reach across equipment to control switches. & Work rest not provided or incorrectly adjusted. 9. Wrong type ot wheel or improperly mounted. Paying Boring operations consist of locating and finishing boles fay means of drills, boring cutters, or reamers. The operations fall into two categories: Boring and drilling. Boring mills employ cutters, while drilling machine? employ pointed or fluted cutting tools. The most prevalent causes of injury in boring operations are: The most common causes of injury* result ing from boring operations may be classified into two catagories. contact with, or struck by. 1. Hair or clothing coming in contact with revolving components. 2. Hands coming in contact with tool r spindle. 3. Struck by broken tools, cutters, or Hy ing chips. 4. Struck by work not clamped securely. W'c have briefly discussed the basic opera tions of machine tools and have also enum erated some of the most common causes of injuries in each group. In general, the three causes of accidents and injuries are urtsafr conditions, unsafe acts, and unsafe attitude-. Providing Safe Equipment Probably the first step in eliminating un safe conditions is providing safe design of our machine tools. In addition, safety in operations can he provided bv: Safeguarding the Point of Operation The first consideration of tins topic should be whether provision can be made to keep the operator's hands out of the danger area. This can be accomplished by providing mech anical loading devices where feasible. Guards or cages may be built around the point of operation or danger zones. Where mechattiol loading devices arc not feasible, pro visions may be made where the operator .1fetal Products Industries 9 reaches into the machine only whoi tlie machine j$ completely stopped or started only when the operator's hands are out of the danger zone. One method is to require two-button controls, requiring the operator to depress two buttons or switches at the -ame time, one with each hand. Proper Clothing ^ Serious accidents can be prevented to* proper dress. Loose dothing, ties, long sleeves, rings, etc^ are easily aught a re volving machinery and should be prohibited in machine shops. Caps should be worn to cover long hair. . Guarding Moving Parts I'resent day machines and equipment gen erally come equipped with sufficient guards ,-n all moving forts however, it may be necessary to insure that all necessary guards are provided. Safeguarding Controls and Machine Requirement of Persona] Protective Equipment The use of personal protective equip ment has. and can prevent, many serious accidents m a machine shop operation. Proper use of goggles, shields and helmets, have prevented flying dips, spark, and bro ken tools from entering the eyes and face, Mechanisms therein* preventing serious injuries. Starting buttons or levers may be guarded in several ways to prevent the machine from Iving accidentally actuated by the operators tr falling objects. Another form of safe guarding controls may be to have certain guards hooked to the power source, so that (he machine will not operate if the guard i< not m tlte correct position. A Clean Place Is a Safe Place to Work Good housekeeping is of prime interest m safety and should be constantly brought to the attention of the employees* Floors should be kept in good repair, dean and free of oD. grease arid dirt. Tools, material, waste and oily nigf all should be placed m the container provided. Everything should Elfanmattng Unsafe Acts and Practices liavc a place and everything kept in its {dace. Because most of the machine shop acci dents. are caused by the human clement, it is necessary to constantly train and super vise the operators. Guards, controls, and de sign help to prevent accidents, but there is always that possibility of failure cm the part of human firings to think and act safely. It i< the responsibility of the Supervisors and Safety Representatives to constantly train, instruct, and assist the employees under their jurisdiction to look ahead to avoid hazards. Awareness of Hazards Much has been done in safety* to guard mechanical equipment and provide personal protective equipment, but - there are situa tions that are always a potential hazard. An example is sharp edge on a piece of metal or rotating parts that cannot be guarded. To prevent accidents m these situations, tt be comes a problem of training and supervi sion. The employee must be instructed or trained that the steel should be handled with gloves or pads, that he must not read) into Utilize Mechanical Safeguards or across revolving parts until the machine Mechanical guards are of no value if they is folly stripped. are nqt in the proper position and adjust* wltm machinery is being operated. Repairs, oiling, and adjustments should be permitted vnly when the machine is turned off and adequate precautions taken so that the machine is locked or tagged. Avoid Horseplay Horseplay, fighting, and practical jokes cannot and should not be tolerated in any phase of industry, particularly in machine shops. Many* injuries have resulted from startled employees bring forced into danger Proper Care and Use of Hand Tools ous areas. It is well to remember that ma Many of our accidents in metal machining are caused by hand tools which are defec tive or used incorrectly, or used for pur poses other than are intended. Hand tools should be made of the best materials to prevent them from breaking, cracking, or becoming dull quickly. It is imperative that hand tools receive constant maintenance. chine tools do not have the ability to think. A machine shop is not a jungle in which you endanger your life by merely^ entering and becoming exposed to massive metal animals, but rather a place where accidents nav occur if common seme, good judge ment, training, and supervision are not ex ercised. 20 1956 Xalional Safety Congress added help ot all non-safety aspects in volved. a program ot press mechanization could \tn` well be launched in your plant.
