Conveyor Safety

Did you know?

No person is allowed to ride a conveyor in the workplace. You may only stand on the supporting frame when the conveyor has been locked out.

Summary

There are many hazards associated with working at or near a conveyor, including being dragged in, crushed or entangled in rotating parts or pinch points, or injured by falling objects. Always take care when working near or on a conveyor.

An employer must:

  • Make sure the conveyor is constructed or installed so that: [N.S. Reg. 44/99, s. 93(2)]
    • There is adequate clearance between the material being transported and a fixed or moving object,
    • Pinch points that a person may come into contact with are adequately guarded, and
    • The conveyor cannot carry materials into a stopped power-driven conveyor, or there are written procedures that provide an equal level of safety.
  • Make sure that emergency stop devices are installed at designated workstations and other locations along the run of the power-driven conveyor. [N.S. Reg. 44/99, s. 93(3)]
  • Make sure that adequate safeguards are in place on moving parts that employees may come in contact with (i.e., chain and sprocket assemblies). [N.S. Reg. 44/99, s. 87(2)]

Note that this topic does not apply to devices that transport people, as the Elevators and Lifts Act would apply. [N.S. Reg. 44/99, s. 93(1)]

When a person is required to cross over a conveyor, the employer must: [N.S. Reg. 44/99, s. 94(1)]

  • Provide an adequate way to cross, and
  • Identify the crossing point.
  • Nobody is allowed to ride on a conveyor or stand on the supporting frame of a conveyor unless the conveyor has been locked out. [N.S. Reg. 44/99, s. 94(2) and (3)]

When objects may fall from a conveyor and injure a person, the employer must make sure: [N.S. Reg. 44/99, s. 95]

  • It is equipped with guards or other protection to stop the objects from falling from the conveyor to the workplace below, or
  • Barriers are installed that prevent a person from being under the conveyor when it is running.

When rollback of the load or belt may be a hazard to a person, the employer must make sure an anti-rollback device is installed to prevent the belt or load from rolling back when the conveyor carries a load up an incline. [N.S. Reg. 44/99, s. 96]

An employee must:

  • Not ride on a conveyor or stand on the supporting frame of a conveyor unless the conveyor has been locked out. [N.S. Reg. 44/99, s. 94(2) and (3)]
  • Comply with the Occupational Health and Safety Act and the regulations. [S.N.S. 1996, c.7, s. 17(1)(f)]
  • Know the location of the emergency "shut-off" devices and how to use them.
  • Know how to work near conveyors safely.
  • Do not try to remove stuck items or debris until the conveyor is locked out.
