TM 9-243SAFETY EQUIPMENT - ContinuedEYE PROTECTIONProper eye protection is of the highest importance for allpersonnel. Eye protection is necessary because ofhazards caused by infrared and ultraviolet radiation, orby flying objects such as sparks, globules of moltenmetal, or chipped concrete and wood, etc. Thesehazards are always present during welding, cutting, sol-dering, chipping, grinding, and a variety of other opera-tions. It is absolutely necessary for you to use eye pro-tection devices such as helmets, handshields, and gog-gles during eye-hazard operations. Appropriate use ofgoggles will limit eye hazards. Some goggles have plas-tic windows which resist shattering upon impact. Othersare designed to limit harmful infrared and ultravioletradiation from arcs or flames by the use of appropriatefilter lenses. Remember, eye damage can be extremelypainful. Protect your eyes.HELMETSProtective helmets (hard hats) come in a variety ofshapes. They may be made of tough polyethylene orpolycarbonate, one of the toughest hat materials yetdeveloped. When falling objects strike the hats, theshock-absorbing suspension capabilities minimizeinjuries.Regular hard hats must be insulated so that personnelmay be protected from accidental head contacts withelectrical circuits and equipment at comparatively lowvoltages (less than 2200 volts).Electrical workers requiring head protection necessaryto their duties or to the working environment, must wearinsulating safety helmets or all-purpose protective hel-mets which must be capable of withstanding 20,000 voltminimum proof-tests.GLOVESUse gloves whenever you are required to handle rough,scaly, or splintery objects. Two types are shown above.Special flameproof gloves are designed for gas andelectric welding in order to limit danger and damagefrom sparks and other hot, flying objects. Personnelworking with electricity are usually required to wearinsulating rubber gloves.Be sure to follow all regulations prescribed for the use ofgloves. Gloves must not be worn around rotatingmachinery unless sharp or rough material is beinghandled. If such is the case, extreme care should beused to prevent the gloves from being caught in themachinery.SAFETY BELTS AND SAFETY STRAPSThe safety belt and safety strap are a must when work-ing in high places. The safety belt, strapped around thewaist, contains pockets for small tools. It also has twoD-rings used to attach the safety strap. The safety strapis a nylon-reinforced leather belt that is placed aroundthe item to be climbed. It is then attached to the twoD-rings on the safety belt. Detailed use of the safety beltand safety strap is described in chapter 49 of thismanual.EAR PROTECTIONProper hearing protection is a must when working withor around certain types of power tools. Some tools arecapable of producing dangerously high noise levelswhich, if ignored, can result in serious hearing loss orinjury. Use the hearing protection regularly.2-4
