Also known as: Hot, Hot conditions, Hot weather, Artificially high temperatures, Artificial extremes of temperature, Extreme heat

How to control high temperatures

Insulate, shield or relocate hot plant and processes, and ventilate roof spaces and plant rooms before work begins.
Use air-conditioning, spot cooling or extraction to lower temperatures in enclosed work areas.
Schedule work in roof spaces and other hot areas for cooler parts of the day, and limit time spent inside.
Monitor conditions with a heat stress tool that considers temperature, humidity, air movement and workload, and adjust work accordingly.
Provide water, rest breaks in cool areas and supervision so anyone showing signs of heat illness is removed promptly.

Typical controls, most effective first. Your SWMS sets the controls for your own job and site.
