Australia Model Code of Practice: Managing the Work Environment and Facilities 2.8a: 2.8 Manage heat and cold exposure and train workers to recognise illness

Workers in extreme heat or cold must be able to work without risk to physical and psychosocial health so far as reasonably practicable, and conditions and worker health must be monitored when exposure is prolonged or repeated. The code distinguishes a threatening condition from mere discomfort, notes that heat-related illness and hypothermia can be fatal, and requires assessment of personal factors (medication, age, health, activity, pregnancy and breastfeeding, clothing, duration) and environmental factors (temperature, humidity, air movement, radiant heat). Training should cover recognising early symptoms in oneself and others, following safe procedures and reporting problems at once.
