Given the Bureau of Meteorology’s recent statement advising that 2018 is the third hottest year on record, it’s even more important that we understand the risks of heat on our body and how we can help prevent heat-related illness. 

We all have a duty of care to manage the risks of working in the heat. Employers are encouraged to ensure workers wear protective gear, including a hat and sunscreen, take adequate breaks, use shade and keep hydrated to prevent heat exhaustion, heatstroke, fainting and cramps.

We also need to be mindful that working in the heat isn’t just an outdoor problem; it can be in any hot environment, including; kitchens, laundries, warehouses, roof cavities, and the list goes on. 

The New South Wales Regulator has released a statement warning that working in hot conditions can cause a range of WHS related issues “including the loss of grip when handling objects due to sweaty hands, mistakes, slips or falls” caused by heat fatigue or fainting. The regulator also reminds us that heat illnesses can be incapacitating or fatal.

We advise that all employers should identify hazards in consultation with workers, WHS reps and other PCBU’s to minimise risks at this time of year. 

What is the difference between heat stress and heat strain?

Heat stress is the total heat load on the body from all sources, and heat strain is how the body responds to heat stress.

Many don’t know that heat kills more Australians than any natural disaster, which is why it’s so important to recognise the signs of heat stress and use preventative measures as listed in our poster.  

Some of the most common signs of heat stress include
  • Normal responses, i.e., sweating
  • Dehydration / elevated core temperature
  • Heat rash/heat cramps
  • Dizziness & fainting
  • Heat exhaustion
  • Heatstroke — Seek urgent medical attention immediately.
What is the difference between Heat Exhaustion and Heat Stroke?

Heat exhaustion is a serious state that can lead to heatstroke. It happens when blood volume is reduced due to excessive perspiration in a hot environment.

Heatstroke is a medical emergency that requires urgent action. It happens when the body’s core temperature rises over 40.5 °C. This is when the body’s internal systems start to shut down and many of the organs suffer damage. If treatment is delayed, it can be fatal.

Did you know that not everyone reacts to heat in the same way?

The way heat affects people varies from person to person and is influenced by:

  • General health
  • Bodyweight
  • Age
  • A low level of fitness
  • Certain prescription and illicit drug use
  • Medical conditions.
