Welding is a method of joining metal parts together by heating them. Arc welding is the most common type of welding process used in construction.
Although welding is a common work practice in many construction trades, welding tasks can expose workers to numerous hazards such as
Breathing in toxic fumes and gases
Starting a fire or explosion
Getting serious burns from hot metal
Receiving electric shocks from welding cable.
This guide is intended to provide information on the health and safety hazards associated with arc welding for millwrights and other associated construction trades such as pipe fitters and sheet metal workers. 20 pages. May 2015.
