Working in high temperature environments can pose serious risks to health and wellbeing. During the Australian summer when the risk of heat exposure is increased, it’s important to understand the signs of a heat affected worker and to know how to respond to heat related illness.
The Dangers of Working in Heat
Working in high temperatures can lead to health issues ranging from mild discomfort to life-threatening conditions. The two most common heat related illness are heat exhaustion and heat stroke.
Recognising Heat Exhaustion
Heat exhaustion occurs when the body overheats due to prolonged exposure to high temperatures and inadequate hydration. It’s important to be able to spot the signs of heat exhaustion and to know what to do if you or a co-worker are displaying symptoms.
Some common signs and symptoms of heat exhaustion include:
- Excessive sweating
- Fatigue and weakness
- Dizziness or lightheadedness
- Nausea or vomiting
- Headache
- Muscle cramps or weakness
- Cool, moist skin with goosebumps
- Rapid heartbeat
First Aid Treatment for Heat Exhaustion
If you suspect someone is experiencing heat exhaustion, it is crucial to take immediate action. Here are the steps to provide first aid treatment:
- Move the person to a cool, shaded area or an air-conditioned environment.
- Encourage them to lie down and elevate their legs slightly.
- Loosen or remove any tight or unnecessary clothing.
- Provide cool water or a sports drink to sip slowly.
- Apply cool, wet cloths or use a fan to help lower their body temperature.
- Monitor their condition and seek medical attention if symptoms worsen or do not improve within 60 minutes.
Spotting the Signs of Heat Stroke
Heat stroke is a severe and life-threatening condition that occurs when the body’s temperature regulation system fails. It’s often characterised by a body temperature above 39.4°C and can lead to organ damage or even death. Some signs and symptoms of heat stroke include:
- High body temperature (39.4°C)
- Altered mental state or confusion
- Rapid and shallow breathing
- Rapid heartbeat
- Dry, hot, and flushed skin
- Lack of sweating, despite the heat
First Aid Treatment for Heat Stroke
Heat stroke is a medical emergency, and immediate action is crucial. Follow these steps while waiting for medical professionals to arrive:
- Call emergency services right away.
- Move the person to a cool, shaded area.
- Remove any unnecessary clothing and attempt to cool them down rapidly.
– Immerse them in a tub of cool water, if available.
– Apply ice packs or cold compresses to their armpits, neck, and groin.
– Use fans or air conditioning to help with cooling.
- Monitor their vital signs until medical help arrives.
Employers have a duty to keep workers and workplaces safe from the risks of working in heat, but by recognising the signs and symptoms of heat exhaustion and heat stroke, and knowing the appropriate first aid treatments, you can mitigate the risks to you and your co-workers.
Remember to stay hydrated, take regular breaks in cool areas, and prioritise your safety when working in hot environments. If you or someone around you shows signs of heat-related illness, don’t hesitate to seek medical assistance immediately.
