Hazards associated with welding processes can also be divided into hazardous chemical agents and physical agents. The chemical hazards include metal and contaminant fumes and gases, and organic vapours that are either used in the welding processes or produced during the processes. The physical agents include noise, radiation and thermal stress. Each of these hazard categories are then associated with specific health concerns in workers.
The links below provide some Canadian content and context on the health and safety considerations which exist in welding. Check out the CCOHS database which the library offers as well for Safety Data Sheets and other key content.
