Safety Hazard Related To Welding
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).
Prolonged exposure to the strong nail-polish remover could cause adverse effects to the human body namely; siderosis, metal fumes fever, system disorders, irritation of respiratory and much more. Ventilation measures should thus be put in place and could involve dilution ventilation which comprises fans such as roof exhaust fans and wall fans using large amounts of air to dilute contaminants to the concentrations below prescribed limits. The most appropriate method of controlling welding fumes and gases is the combination of general dilution ventilation and local exhaust (Reese, 2012).
For all welding and cutting operations, the welder must wear protective clothing as well as hearing protection. The welder should also ensure that his gloves are dry at all times especially when using the torch tip as grease is flammable and contact between the two could burn his hands (Swartz, 2001).
