6.7 Weather – copy

Weather events are a continual challenge.

  • Use your discretion and common sense in developing safe work habits in extreme weather.
  • When weather conditions create hazards to workers, additional precautions must be taken as necessary for the safe conduct of work.


  • Be aware of the potential for overhead hazards such as snags and widow makers.
  • Stay out of decadent stands and snag patches on windy days.
  • Freshly logged boundaries and right-of-ways can be extremely hazardous during wind storms.
  • Leave the timber when debris begins to fall from the canopy.
  • When wind gets too bad, pick lulls in the wind to travel when walking or driving.
  • If possible, find an alternative area to work in.

Rain & Snow
  • Ensure you are dressed appropriately
    • Rain gear, boots, and warm clothing
  • Rain
    • Avoid working below fresh cut slopes during heavy rains. Cut banks may slump or rocks may come loose.
    • Footing in all terrain becomes worse in wet weather – prepare for slips, trips, & falls.
    • Follow rainfall shutdown guidelines set by the client or project manager.
    • Avoid working in steep terrain during heavy rains.
      • Consider your access road to the work area and the impacts of overflowing creeks, debris torrents, and landslides.
    • Snow
      • Use rubber caulks instead of leather soled boots to keep snow from sticking
      • Be sure of your footing when walking in snow covered areas and use extreme care walking on frozen snow covered sidehills.
      • Avoid walking in felled & bucked (F&B) timber when covered in snow or ice.
      • Use caution when brushing in snow bent brush that may spring back when cut.


  • Lightning has visited most all outdoor work environments. Anticipate a high-risk situation and move to a low-risk location.
  • Specifically:
    • Suspension and resumption of work activities should be planned in advance.
      • Safe evacuation sites: fully enclosed metal vehicles with the windows up, substantial buildings, low ground – seek cover in clumps of bushes or uniform timber.
      • All outdoor metal objects (power/light poles, fences, gates, metal bleachers, electrical equipment, and mowing and road machinery.
      • AVOID: solitary trees, water, open fields, high ground, and caves.
    • If hearing ‘crackling noises’ or your hair is standing on end you are in lightning’s electrical field.
      • Get to cover ASAP
      • If unable to find cover, remove all metal objects, place your feet together, duck your head, and crouch down low in a ‘baseball catcher’s stance’ with hands on your knees.
      • Wait a minimum of 30 minutes from the last observed lightning strike or thunder before resuming activities. Be cautious during this time as the storm may not be over.
