Tip 2. Perform Daily Maintenance and Cleanups

The high wind speeds that occur during a thunderstorm have enough power to pick up stray materials and toss them around. Construction sites are especially vulnerable to these high winds due to the number of stray materials lying around. These materials can be anything from piles of dirt for earthwork projects to timber and steel for building projects.

This is why it is a good idea to perform daily clean-up activities in and around the construction site. This means picking up materials that are not in use and bundling or covering them up to ensure they will not get blown around during a thunderstorm. Once a storm hits, you will have little time to think about and coordinate these activities so it is best to do them when the sky is clear.

No matter how prepared you are for a lightning strike, you can never be sure that everyone will stay 100% safe. This can be due to uneducated workers not following the correct safety procedures or forgetting their thunderstorm safety training altogether. You can assert control in these situations by educating yourself on what to do in the odd chance that someone is hit by a lightning strike.
