Why We Do It
  • Guarding
      • Does your equipment have adequate guarding to ensure employees can’t get hurt?
      • Did the guarding come with the equipment and is it up to local standards?
        • Retrofit guarding is only adequate if it meets current standards
      • Have any of the safety measures been tampered with or removed?
  • Racking and Stacking Structures
      • Do you have materials, articles or things stored on a structure like a rack or stacking structure? All of the following require a PSR:
        • Industrial pallet racks
        • Moveable shelf racks
        • Stacker racks
        • Drive-in and drive through racks
        • Cantilever racks
  • Spray Booths
    • A PSR is required if a process involves a risk of ignition or explosion that creates imminent hazard to a person’s health or safety

  • Lifting Devices
    • Lifting Devices, Flammable Liquid, Dust Collection, Molten Metal and Chemical Processing also may require a PSR.

  • Exemptions
    • Even with exemptions to a PSR, you are still required to maintain adequate documentation of the exemption.

  • Fewer WSIB claims improve morale and reduce insurance premiums.
  • Reduced lost time injuries increases productivity.
  • A safe work environment is not only the best business environment, but it is the RIGHT work environment for your employees to perform safe profitable work.
