Hazard summary

Mine workers who are required to work around conveyor belts may be at risk of serious injury or death if conveyor ‘pinch points’ are not properly guarded or if the conveyor is not stopped, de-energized and locked out and tagged before works starts on the conveyor.

What you’re required to do by law

Guarding pinch points

Under section 196 of Regulation 854 - Mines and Mining Plants pinch points must be guarded on a conveyor at:

  • head, tail, drive, deflection and tension pulleys
  • return and carry rollers if the lift of the belt is restricted

If it’s impractical to guard these components, a fence, barricade or gate with an interlocking device must be in place to prevent workers’ access to the pinch points.

If the position or construction of the conveyor provides protection that is equivalent to a guard, fence, barricade or gate with an interlocking device and makes the pinch points inaccessible, then none of these devices is required.

Conveyor maintenance

Workers must be trained in locking and tagging procedures.

When a conveyor is being repaired, adjusted or maintained, subsection 196(6) of Regulation 854 requires the conveyor to be stopped and the prime mover de-energized and locked and tagged out, unless:

  • it is necessary to run the conveyor during the repairs, adjustments or maintenance; and
  • effective precautions are taken to prevent injury to a worker from moving parts

Emergency stopping

By law every conveyor must have an emergency stopping system that complies with section 196.1 of Regulation 854.

Risk assessments

Under section 5.1 of Regulation 854, employers must conduct a risk assessment which considers the:

  • nature of the workplace
  • type of work
  • conditions of work at that workplace
  • conditions of work common at similar workplaces

After the risk assessment has been conducted, sections 5.2 and 5.3 of Regulation 854 require employers to:

  • give the results to the joint health and safety committee or representative
  • develop and maintain measures to eliminate where practicable, or control where impracticable, the hazards or potential hazards identified in the risk assessment
  • consult with the joint health and safety committee or representative on developing these measures
  • review the risk assessment as often as necessary, at least once a year

Recommended precautions

To help prevent injury or death from conveyor belt accidents, employers should make sure that effective precautions are in place to protect workers. For example,

  • guards should be rigid and secure and openings small enough so that workers are at a safe distance from the pinch points, in case contact is accidentally made with a guard
  • guards should be installed to prevent injury whenever a worker has access to a loading, unloading, work station, transfer or discharge point
  • any work on the conveyor requiring the conveyor to be operating should be identified, and measures and controls needed to ensure that workers are safe while doing this work should also be clearly identified, for example:
    • extending grease lines to outside the guards
    • moving conveyor belt adjusters outside the guards so guards do not have to be removed while maintenance or adjustments are being carried out
