Avoiding heat stress

Managing the risk of heat stress and dehydration is important for workers exposed to harsh conditions and especially during the summer season.

Most people have an average core body temperature of around 37˚C in hot environments, or where internal temperature is raised through exercise.

Heat stress prevents normal cooling mechanisms from working properly and may lead to heat-related illnesses, including heat rash, exhaustion, cramps, dizziness and fainting, and life-threatening heatstroke. Heatstroke occurs when the core body temperature rises above 40.5 °C and the body's internal system starts to shut down.

Remember workers can be overcome by heat even when hydrated. Be mindful to plan ahead when scheduling outdoor work by modifying the work to suit the environment or modifying the environment to suit the work at hand.

Watch the Melting Man story which outlines the tragic consequences that can occur if heat strain factors are not adequately controlled.
