What Are The Risks Of Working In The Heat?
Extreme heat can cause workers to feel nauseous, dizzy, weak or fatigued, collapse, faint or suffer convulsions; or develop conditions such as:
- Heat exhaustion
- Heat cramps
- Heat rash and
- Heatstroke, which is life-threatening
Extreme
heat can also exacerbate an existing illness. Failing to deal with heat
issues in your workplace not only affects your workers' health, it can
also lead to errors and inefficiencies in completing work tasks, and can
negatively affect workers' morale. Workers are most at risk when the
temperature and humidity are high and there is limited ventilation.
New
workers who are not used to working in hot conditions are most at risk
of suffering heat-related illnesses. It is therefore important to
acclimatise new workers to the conditions by gradually increasing the
workload or giving them additional breaks when they first start working.
12 POINT CHECKLIST TO REDUCE HEAT RISKS
Use the following checklist to reduce the risks associated with working in the heat:
If possible, schedule outdoor work early in the morning or late in the afternoon or evening to avoid the hottest times of the day
Where possible, have workers work in a shaded area. Consider installing temporary sunshade equipment, such as awnings, shade cloths, umbrellas and tents
Allow outdoor workers to rest in a shaded area when temperatures reach an unsafe level. This will vary depending on the humidity and exposure time
Increase the number of breaks, or allow your workers to opt for additional breaks when they feel overheated
Provide workers with water, and encourage them to stay hydrated
If possible, isolate the heat source, e.g. with a temporary wall, during the period that most work is being performed
Ensure your workers are wearing appropriate clothing e.g. hats and loose-fitting, breathable, long-sleeved shirts for outdoor work. Balance this with the risk that the clothes may be caught in a nip point of equipment the worker needs to use, such as a wood chipper
Provide workers with sunscreen and encourage them to regularly apply it
Avoid having your workers work in direct exposure to the sun or another heat source by relocating the work where possible
Increase ventilation using air conditioners or fans
Direct your workers to cease work once the temperature becomes too hot
Have an emergency plan in place if there is a significant risk of a bushfire, including providing appropriate fire-fighting equipment
