Also there is the dan ger of lamee from fires in ships on the ways and in the water after launching. Many of these fires oc cur because welders, taekers and burners do not observe the rule re quiring them to know what is be low or above, or on the other side of bulkheads betore starting work. Sparks will often ignite welding leads, portable, light wires, air hose and rubbish, especially when house keeping, or as we call it, shipkeep ing, is poor. More than 90 per cent of these fires are caused by failure to observe this important rule. Although many of the fires may be minor, there is always the pos sibility of men being trapped by smoke and toxic fumes without pos sible escape. This is where the trained safety inspector or watch force man comes into the pictnre. Quickly he must don a mask, hook on a life rope, and go down to make sure everyone has escaped. He must be followed as closely as possible by another worker with a powerful electric lamp. If any deficiency of oxygen is suspected, an oxygen breathing mask must be worn, ventilation must be provided at once, smoke and fumes exhausted, and a fresh supply of air blown in. Much couid be said about the Hwttmmi Serfetr Hews, 4*#, 944 maximum allowable concentration for carbon monoxide and carbon dioxide, but tne main point to re member is that carbon monoxide is the No. 1 poison killer in both in dustrial and non-occupational life. Wherever there is smoke, you may suspect carbon monoxide. Constant alertness on the part of watch force men and safety inspec tors is an absolute necessity in com bating such hazards The education of the men by their supervisors-and use of warning posters are recom mended. but exhaust ventilation and introduction of fresh supplies of air ars imperative under such danger ous conditions. A number of almost fatal accidents in shipbuilding can be attributed to carelessness rather than ignorance. Men forget to think. Use of insulation cement contain ing toxic solvents, such as carbon tetrachloride, is a menace to work men unless adequate precautions are taken to safeguard them. A large shipyard recently re-distilled its en tire supply of a toxic solvent and substituted a safer one, thus elimin ating the hazard without loss of ma terial, but with a tremendous in crease in production and safety. The use of water-repellent asbes tos insulation has recently replaced some types of material formerly used in ship work. For protection against dust or possible asbestosis, it is recommended that such mate- (C o ntim tfd e*t pagt 90) A tUrrsed veefcee WMriae esrew-bmth.
