With the advent of hotter and drier summers, workplaces are becoming increasingly susceptible to heat-stress related claims, with those working in vulnerable sectors such as agriculture, construction and frontline services particularly at risk. Without a legal maximum safe working temperature, and with increased awareness resulting in an increase in reporting of hazardous conditions, employers in high risk environments should review risk assessments and heat mitigation protocols in order to safeguard the health and safety of employees, and mitigate the risk of personal injury claims and regulatory prosecutions. Increased sun exposure is also likely to require employers to consider protective measures, including limiting the time workers spend in the open air and providing appropriate protective equipment, as well as utilising advances in wearable health monitoring devices.
