22.L Elevating Aerial Work Platforms (AWPs).

22.L.01 All elevating aerial work platforms (AWPs) must be designed and constructed in accordance with ANSI/SIA A92.3, ANSI/SIA A92.5, and ANSI/SIA A92.6, as appropriate.

Boom Lift and Scissor Lift

22.L.02 AWPs must be operated, inspected, and maintained as specified in the operating manual for the equipment.

  1. AWPs must comply with requirements of this Section and Section 18.G.
  2. Records of inspections conducted while the unit is at the work site must be maintained at the work site.
  3. Height-to-base width ratio of the scaffold during movement is 2:1 or less, or per manufacturer's instructions.
  4. All elevating AWPs must have the manufacturer's operating manual readily available on the equipment.
  5. AWPs will not be operated unless the access door or chains are in the closed position.
  6. Fall protection must be used in accordance with Section 21.K of this manual.
  7. Climbing of the rails is prohibited.

22.L.03 All boom-supported AWPs must be equipped with an alarm, or other suitable warning device, at the platform. The alarm must be in operable condition and must automatically activate when the machine base is more than 5º out of level in any direction.

22.L.04 All AWP operators must have training that includes both general as well as equipment specific familiarization before being allowed to operate this equipment. Training must be documented.

22.L.05 Before operating the AWP the operator must:

  1. Survey the work area for loose or soft ground, ditches, drop-offs or holes, bumps and floor obstructions, debris, overhead obstructions, ground and elevated energy sources, and other possible hazards;
  2. Ensure the AWP is on a firm, level surface;
  3. Ensure the AWP is loaded in accordance with the manufacturer's specifications;
  4. Ensure that outriggers and/or stabilizers are used if required by the manufacturer;
  5. Ensure that, if the vehicle is on wheels, the wheels are locked or chocked; and
  6. Ensure that the fall restraint system is connected.

22.L.06 These AWPs must not be used by persons working on energized electrical wiring and/or equipment.

22.L.07 AWPs must only be operated from the ground position in an emergency (rescue), for maintenance, or when unoccupied.

22.L.08 Lift controls will be located below the guardrail height. When lift controls are not located below the guardrail height an aftermarket guard will be installed.

22.M Vehicle-Mounted Elevating and Rotating Work Platforms (Aerial Devices/Lifts).

Aerial work platform tips due to improper operation.

22.M.01 Vehicle-mounted elevating and rotating work platforms (aerial lifts, to include articulating boom platforms/lifts (knuckle boom lifts), trailer-mounted boom lifts) must be designed and constructed per ANSI/SIA A92.2.

22.M.02 Vehicle-mounted elevating and rotating work platforms must be operated, inspected, tested, and maintained as specified in the operating manual for that piece of equipment.

  1. Vehicle-mounted elevating and rotating work platforms must also comply with requirements in Sections 18.G and 21.
  2. Records of inspections conducted while the unit is at the work site must be maintained at the work site.
  3. All aerial devices must have manufacturer's operating manual readily available in or on the vehicle.
  4. If the unit is considered rated, and used as an insulating device, copies of the electrical insulating components and system tests conducted while the unit is at the work site must be maintained at the work site.
  5. All required safety decals, labels and signs must be in place and readable.

22.M.03 Only personnel trained in the use of the vehicle-mounted elevating and rotating work platform must be authorized to operate it. Training must consist of:

  1. Reading and understanding the manufacturer's operating manual and any associated rules and instructions, or training by a QP on the contents on these documents; and
  2. Reading and understanding all decals, warnings, and instructions on the vehicle- mounted elevating and rotating work platform.
