Say this

  1. When you hear thunder or see lightning, stop work. Do not finish the job first.
  2. I will show you our lightning shelter. It is a proper building. Not the tool shed, not the canopy, not under a tree.
  3. Get down from cranes, scaffolds, roofs and ladders. Stay away from fences and metal pipes.
  4. We wait 30 minutes after the last thunder before going back out. I will give the all-clear.
  5. In strong wind, tie down or bring in loose sheets and materials. Lifts and gondolas stop at their wind limits.
  6. In heavy rain, get out of trenches, pits and basements. Wet ground can collapse.
  7. After the storm, nobody uses a scaffold, lift or crane until it has been checked.

Ask the crew

  1. What do you do the moment you hear thunder?
  2. Where is our lightning shelter?
  3. How long do we wait before going back out?
  4. Why do we leave trenches in heavy rain?

Show them

  • The route to the lightning shelter from today's work area.
  • The myENV alert on the supervisor's phone and how you will be warned.
  • The tie-down points and storage for loose materials.
