Manufacturing Hazards


The manufacturing sector is a diverse and complex industry consisting of various types of workplaces, including automotive, food and beverage, wood and metal fabrication, textiles and printing, chemical, rubber and plastics, ceramics, logging (sawmills) and pulp and paper.

Workers can be exposed to a number of hazards in this sector that can result in serious injuries, occupational illness or even death. Included are hazards involving:

  • machine hazards such as in-running nip hazards, exposure to moving parts and exposure to hazardous motion if equipment is not properly locked and blocked during maintenance and repair

  • improper or non-existent guarding and lockout of machines and equipment.

Other hazards that may be present in a manufacturing workplace may include:

  • musculoskeletal disorders (MSDs)

  • occupational disease arising from noise

  • chemical exposures, and

  • workplace violence and harassment
