Work dangers rise with temperatures

As temperatures rise above 40°C this summer, SafeWork SA reminds workplaces to ensure they have measures in place to cope with the heat.

“Hot weather is a hazard that needs to be considered when planning work activities,” said A/Executive Director Robin Scott.

“Heat stress can afflict workers at outdoor locations such as construction sites, storage yards, tarmacs, roads and farms.

“It is also important to recognise that heat poses a risk in confined spaces. Temperatures in industrial sheds can exceed 50°C, placing workers at risk.

“Working in a hot environment can impair workers’ concentration and judgement, which heightens the chances of other harmful incidents occurring,” Scott said.

Heat stress symptoms may include: headaches; fatigue; dizziness or fainting; increased sweating; mood changes such as irritability or confusion; and possibly an upset stomach or vomiting.

“Continuing to work when you experience the symptoms of heat stress can lead to serious illness and in extreme cases, death,” Scott warned.

SafeWork SA recommends the following measures to avoid heat-related risks in the workplace:

• Schedule work so that more physically demanding tasks are done during the cooler times of the day.
• Rotate workers who have to work in direct sunlight - doing so can help reduce the length of sun exposure for each person.
• Where possible, provide artificial shade such as umbrellas or a sunshade.
• Keep well hydrated - South Australian workplace safety laws require that fresh drinking water be provided at all workplaces.
• Ensure adequate ventilation. Wherever possible, the work environment should be ventilated by the use of fans or other means.
• Provide UV protection. Sunblock and wide-brimmed hats should be supplied as part of personal protective equipment.
