Identifying, Assessing, and Controlling Hazards

Mechanical Hazards


Physical factors that can cause injury from mechanical action. Examples include machinery with moving parts, tools with sharp edges, and equipment that can cause crushing or entanglement.

Mechanical Hazards
Construction Industry Examples
  • Rotating parts on power tools
  • Moving machinery (cranes, excavators)
  • Sharp edges on metal sheeting
  • Nail guns
  • Saw blades
  • Crushing hazards from heavy materials or equipment
  • Entanglement in power take-off shafts or drill presses
Tips on Identifying
  • Identify entanglement hazards.
  • Assess friction and abrasion hazards.
  • Locate cutting or severing hazards.
  • Identify shearing hazards.
  • Locate stabbing or puncturing hazards.
  • Assess impact hazards.
  • Identify crushing hazards.
  • Locate drawing-in or trapping hazards.
  • Assess injection or ejection hazards.
