Safety Alert: Heat stress in underground metalliferous mines

Heat stress occurs when the body’s means of controlling its internal temperature starts to fail. Air temperature, humidity, air flow, work rate, acclimatisation, radiant temperature and clothing (including personal protective equipment) are all factors that can contribute to heat stress.

It may not be obvious to underground workers that they are at risk of heat stress. Workers may be exposed to heat stress and other potentially harmful health effects from working in hot and humid conditions underground.

The Resources Regulator has published a fact sheet on dealing with heat stress in underground metalliferous mines.
