A nonprofit involved in construction/renovation projects should have policies in place which instruct supervisors on when to suspend work on a project due to weather conditions. Certain weather conditions can compromise the safety of their staff and volunteers, including rain, lightning, ice, snow, high winds, and excessive heat.
Outdoor work should be suspended if any of the following conditions exist: rain, lightning, ice, snow, high winds, and excessive heat. Indoor work can continue if the structure is sufficiently enclosed to protect workers from such conditions. However, excessive heat can pose a problem to workers indoors, if there is not sufficient air circulation within the structure.
