Heat Stress in the Construction Industry

Working in the sun, especially in Queensland, for a long period of time without adequate breaks, shade or water can mean workers face serious dehydration and are at risk of a heat-related illness or even death. Employers must provide protection for their workers from the heat and sun - and workers must follow their employer’s instructions regarding heat stress and sun safety.

In other recent events, a road worker was transported to hospital for heat related treatment and the following day a housing construction site worker at Miles received treatment by ambulance officers for heat stress.

Late last year, a 25 year old worker died and his colleague was hospitalised with severe dehydration after walking just 6km in 45 degree heat when they couldn't free their bogged vehicle in the Simpson Desert.

Workers are most at risk during heat waves when temperatures are above the average for three or more days, with high humidity increasing the risk.

Very hot and extreme heat conditions can lead to heat-related health problems such as cramps, exhaustion, heat stroke, and fainting. Employers should weigh up all factors such as heat, humidity, water intake, breezes, protective gear, the physical condition of workers and their hours of work.

Recently a project we carried out on a large roof, we identified heat stress as a risk and implemented the use of camel packs, broad brim hats, long sleeve shirts, ice cold water refills, electrolyte first aid concentrate, sunscreen, rotational breaks off the roof every hour and allowed the workers to wear shorts.

These precautionary steps not only assisted in the project seeing completion with zero safety concerns, we came under budget because productivity was maintained throughout the extreme heat conditions experienced.

Safety when when it comes to heat stree doesn't cost money, it saves and can increase productivity.
