Learnings and Suggestions: 

 Both of these cases involved an apparent lack of hazard recognition regarding stored energy. As Western Forest Products has many devices which contain similar hazards (stackers, sorters, press rolls, etc) please take time to identify and discuss these hazards with people at your site.

Consider the following:

  • What is the potential? (Gravity, electrical, hydraulic, air, etc)
  • What lockout/Pin or bracing exists?
  • Are you trained?
  • Is there a written procedure to fix the upset?
  • Have you used a hazard recognition process such as RADAR/Safe Start?
  • You and Your Family. Please take the time to ensure you have considered all the risks.
