Part 39 Tree Care Operations

Highlights

This Part applies to arboriculture activities that involve pruning, repairing, maintaining or removing trees or cutting brush if a worker works at height and depends on the tree for support.

  • Section 793 requires employers to develop and implement safe work practices and procedures. (Section 8 of the OHS Regulation requires that the procedures be in writing and available to workers.)
  • Section 794 allows workers to use a work positioning system when it is not reasonably practicable to comply with the fall protection requirements of section 139.
  • Section 795 requires, at a minimum, that workers using a work-positioning system use a sit harness approved to one of the listed sit harness standards. “Approved” means that the harness meets one of the listed standards and bears the approval or certification mark of a nationally accredited third-party testing organization. A manufacturer’s self-declaration of compliance is not acceptable. A full body harness approved to one of the other listed standards is acceptable.
  • Section 796 allows employers and workers to use knots in place of rope grabs.
