Chapter 57: Heat Illness Prevention
The purpose of this program is to prevent heat illness.
It covers identifying high-heat working conditions and implementing controls to mitigate the hazards of working in those conditions.
It applies to workers, supervisors, field construction and service managers and points of contact, the heat illness prevention program manager, and subcontractors.
These requirements must be followed when work activities (outdoor or indoor) could reasonably be expected to expose workers to the risk of heat illness, namely, when temperatures exceed 80°F.
