Part 1:  Details of Regulated Work or Regulated Product

This safety order is issued to all owners of existing conveyors used for the purpose of transporting skiers, riders or foot passengers uphill at locations used for recreation and the owners of any new conveyors installed after the date of issue of this safety order.

During the 2016/2017 operating season there were two serious incidents in British Columbia which involved employees conducting maintenance on conveyors – one which was fatal.  In both cases the worker was exposed to moving, rotating equipment while conducting maintenance tasks. In addition to these incidents, there have been numerous reported injuries to workers throughout North America sustained while maintaining this type of equipment.

Part 2, section 1 through 3 of this safety order shall be in effect prior to October 15, 2018. Prior to the completion of the requirements outlined in sections 1 through 3 of this safety order, section 4 of this safety order shall be met.

Documentation as required in section 4 (b) of this safety order shall be submitted to BCSA for review within 30 days of the issuance of this safety order. No work shall be undertaken prior to submission of the required documentation.

Part 2:  Requirement(s) of this Safety Order

All owners and contractors of conveyors are responsible for complying with the following requirements of this safety order.

  1. Access to Equipment
    1. Electrical Protective Devices: Where a hazard from moving equipment is present at locations where visual inspections or adjustments are made, electrical protective devices shall be provided which will cause the electric power to be removed from the drive motor when points of access such as panels, hatches or doors are opened or removed. The electrical protective devices shall not be dependent solely upon springs to open.
    2. De–energization and lock out: The electrical protective devices shall not be considered a lock out device. If any maintenance work other than adjustment and visual inspection is conducted, the de-energization and lock out requirements of WorkSafe BC and the CSA Z98-14 shall be followed. 
  2. Inspection Control: Each conveyor shall be provided with inspection controls to provide constant pressure operation when inspection or adjustments are conducted.

    Inspection Control Requirements:
     
    1. Transfer Switch: A switch for transferring the control to inspection operation shall be provided at each location where adjustments or inspections are conducted.
      1. The switch shall have two positions and be labelled “NORMAL” and “INSPECTION”. 
      2. When in the “INSPECTION” position the movement of the conveyor shall be only possible with the use of a constant pressure operating device located where the transfer switch was operated from.
      3. Where more than one transfer switch is in the “inspection” position then all constant pressure operating devices at all locations shall be inoperative.
         
      Note: It is permissible to by-pass the electrical protective device (1 (a) above) for the access panels, hatches and access doors when transferring control to “INSPECTION”.  All other electrical protective devices shall remain operative.
       
    2. Constant Pressure Operating Device: The constant pressure operating device shall:
      1. Allow movement of the conveyor by constant pressure only.
      2. Be protected against accidental contact.
      3. Be situated in such a manner that the maintenance personnel shall not be able to contact the moving equipment and maintenance personnel shall be able to observe the moving equipment from the operating device location.
      4. Provided with an emergency stop switch located adjacent to the constant pressure operating device and when activated shall cause the conveyor to stop as quickly as practicable.

        Note: All changes to electrical equipment shall be approved by the manufacturer or by a professional engineer registered in the province of British Columbia. All electrical schematics shall be updated accordingly.
         
  3. Guarding:
    When the provisions of part 2, sections 1 through 2 are not possible due to electrical constraints of the conveyors controller, guarding shall be installed. The manufacturer or a professional engineer registered in the province of British Columbia shall provide a written statement as to why the requirements of part 1 through 2 cannot be met for each conveyor installation.

    The design of the guarding shall meet, but not be limited to, the following requirements:
    1. Open framework to allow visual inspection of rotating and moving equipment.
    2. Reject a ball no greater than 25 mm in diameter.
    3. Only be removed with the use of tools.
    4. Designed and stamped by a professional engineer registered in the province of British Columbia.
    5. All welding shall comply with the requirements of section 4.8 of the CSA Z98-14 code.

      Note: CSA Z432 should be used as a guide when designing guarding.
       
  4. Safety Procedures:
    1. Management shall provide written safety procedures to be used when maintenance, inspection and adjustments are carried out on conveyors.
    2. Management shall provide a document which is signed by all individuals maintaining, inspecting or adjusting a conveyor stating that the individual who is maintaining, inspecting or adjusting a conveyor has read and understands the safety procedures. These documents shall be available to the safety officer upon request.
    3. Only qualified individuals shall be permitted to maintain, inspect or adjust conveyors.
       
  5. Permits and Inspections:
    The addition of electrical protective devices, inspection controls and/or guarding shall be considered an alteration.
    1. A technical submission shall be filed for each conveyor with BCSA.
    2. An alteration permit acceptance inspection shall be completed by a safety officer before the conveyor may be used for public operation.
