Checklist for risk-managing heat in the workplace

Are ambient conditions  hot?

This contributes to incidents such as heat-related illness and burns.

Are days and nights hotter than usual?

A heatwave can make it harder to sleep and workers may become fatigued.

Is it humid?

High humidity makes it harder for the body to cool itself.

When is work done?

Certain times of the day and year will be hotter.

How often can workers take breaks somewhere cool?

Working in heat for long periods of time is very dangerous.

Is there air movement or a breeze?

This can help cool workers.

Is the work intense or long?

The harder the body is working the more heat it needs to lose.

Are workers physically fit and acclimatised?

Fit and acclimatised workers generally have higher heat tolerances.

Do workers wear hot clothing (including PPE)?

Some clothing can prevent the evaporation of sweat or prevent air movement.

Are the workers qualified, trained and experienced?

Experienced workers may be more efficient and use less energy for the same work. They may also be more aware of the hazards, health effects and controls.

(If known) do workers have medical conditions?

Some conditions and medications can make workers less able to cope with heat.

Is there cool drinking water or electrolyte drinks on hand?

Dehydration can be dangerous and contributes to heat-related illness.
