Physiological Heat Exposure Limit, or PHEL, is the U.S. Navy’s method for managing occupational heat stress using work-rate based heat exposure curves. These curves are built around WBGT, which means accurate environmental heat measurement [...]

EPRI’s heat stress research emphasizes the importance of using practical monitoring tools to better protect workers in the electric power industry. As heat events become more frequent and intense, utility [...]

The Health Impact Investment Platform (HIIP) prioritizes investments that produce measurable positive health outcomes for workers and communities. Accurate environmental monitoring, especially WBGT-based heat stress monitoring, helps investors and employers quantify and reduce [...]

ACGIH TLV heat stress guidelines are widely used to help employers manage worker exposure to hot conditions. The goal is to keep heat stress at levels that healthy, acclimatized workers can sustain for hours [...]

ASHORE flag conditions are used to communicate outdoor heat risk and help for better safety decisions during hot weather. When the flag level rises, it signals increasing danger from heat stress, which makes [...]

Heat stress is a serious safety issue in industrial environments, especially where workers are exposed to high temperatures, heavy workloads, or PPE that traps heat. OSHA requires employers to protect workers from recognized [...]
