Mitigating Welding Safety Hazards in Practice

The welder is in a potentially hazardous environment in that acetylene though not especially toxic, it could contain impurities that are harmful such as traces of phosphates and arsine when generated from calcium carbide. This procedure is extremely flammable whereby its danger is related with instability particularly when it is pressurized. Unlike all the other ordinary flammables these are extremely exothermic reactions that do not need any oxygen to proceed. With extreme violence acetylene can explode if the absolute pressure of the gas exceeds the safe limit which is 101 k Pagage should thus not be exceeded (Puskar, 2013).
