Be heat vigilant this summer

Extreme heat is a growing challenge for Australian workplaces. With climate change driving more frequent and intense heatwaves, the risk of heat-related illness and injury is rising. Employers and employees must be proactive to keep everyone safe and maintain business continuity.

Climate change and worker safety

Climate change is increasing the frequency, duration, and severity of extreme heat events across Australia. Projections show a significant rise in the number of very hot days each year, affecting both outdoor and indoor workers. Industries such as agriculture, construction, and emergency services are especially vulnerable, but any workplace without adequate cooling or ventilation is at risk.

Rising temperatures can lead to:

• More cases of heat exhaustion and heat stroke
• Reduced productivity and concentration
• Higher rates of workplace accidents
• Increased demand for workplace adaptations, such as cooling systems and flexible work hours

Latest statistics: Heat-related claims and costs

Safe Work Australia reports:

• Between 2009–10 and 2018–19, there were 1,774 accepted workers’ compensation claims due to working in heat.
• Most heat-related claims occur in agriculture, construction, manufacturing, health care, and transport.

Understanding and managing heat hazards

Safe Work Australia recommends a systematic approach to managing heat risks:

• Identify hazards: Assess air temperature, humidity, radiant heat, and physical activity levels.
• Monitor conditions: Track weather forecasts and heatwave alerts.
• Implement controls: Provide shade, ventilation, and cooling equipment. Adjust work schedules to avoid peak heat periods.
• Educate employees: Train workers to recognise symptoms of heat stress and encourage regular hydration.
• Review policies: Update your heat management plan to reflect the latest guidance.
