MHSA History The Manufacturers' Health & Safety Association (MHSA) was formed in 1992 at the request of the metal fabricating industry in order to reduce injuries in the steel fabricating industry. The MHSA was originally the Metal Fabricating Health & Safety Association. The name was changed in late 1999 to allow companies in the entire manufacturing sector to have an association they could work with regarding occupational health & safety and Workers' Compensation issues. The MHSA is funded through a levy on the companies Alberta Workers' Compensation Board (WCB) premium assessment. The Association has been involved in the Partners in Injury Reduction Program since 1994.
