Week 29: Machine Guarding (Conveyors)

Conveyor Systems

Objective: An overview of safety considerations for working around conveyor systems

A conveyor system is difficult to guard due to its many hazards. Safe operating practices are an essential part of minimizing conveyor systems hazards.

safeguarding

Example Hazards

  • In-running nip points between rollers and belts
  • Pull-in hazards
  • Crush hazards between products and the conveyor
    or between the conveyor belt transfers
  • Products falling off the conveyor
  • Drive mechanism hazards

Safe Operating Practices

  • Do not use conveyor systems without first receiving proper authorization and training.
  • Assure that all safeguards are in place, and never remove or alter guards.
  • Keep controls and surrounding areas clear of obstructions.
  • Assure all people are clear of the conveyor, and warn people when it is about to start.
  • An alarm must sound prior to the start-up of conveyor systems.
  • Inspection and testing must occur before use. Assure that the e-stop is working.
  • Never sit, ride, or climb on conveyors.
  • Do not overload or exceed the equipment’s recommended capacities.
  • Watch for material jams or malfunctions: if they occur, stop the machine and perform lockout/tagout. Service must only be performed by authorized maintenance personnel.
  • Keep fingers, hand, arms, and clothing clear from all moving components. Use tools or metal hooks to prevent hand and arm injuries.
