Part 9 Fall Protection


  • Section 138 allows rescue personnel involved in emergency rescue training or in providing emergency rescue services to use equipment and services other than those specified in this Part.
  • Section 139 requires employers to ensure that workers use a fall protection system under these conditions:
    • if a worker could fall 3 metres
    • if a worker could fall less than 3 metres and there is an unusual possibility of injury. An unusual possibility of injury refers to the potential for a worker to sustain injuries more serious than those likely to result from landing on a solid, flat surface.
  • Section 140 requires employers to prepare a fall protection plan if a worker at a work site could fall 3 metres or more and is not protected by guardrails. The plan must include procedures for rescuing workers who have fallen.
  • Section 141 presents comprehensive minimum worker training requirements that can serve as the basis for a training course curriculum. Both theory and hands-on components are required.
  • Sections 142 through 149 list equipment requirements. The 2009 edition of the OHS Code marks the first time that Part 9 accepts fall protection equipment approved to standards from the US and Europe. Fall protection equipment approved to any one of these standards is considered to offer an equivalent level of worker protection. Employers and workers in Alberta now have access to a broader range of equipment to safely meet their fall protection needs.
  • Section 152 requires fall arrest anchors to have a minimum breaking strength of 16 kN (3600 lbs), a reduction from the previous value of 22.2 kN (5000 lbs), specifies the limits for free fall and maximum arresting force.
  • Section 156 lists requirements applicable to boom-supported elevating work platforms and aerial devices, and forklift mounted work platforms.
  • Section 158 presents requirements specific to fabric and netting leading edge fall protection systems.
  • Section 160 introduces new requirements specific to work positioning.
