Extremely hot or cold environments are places where temperatures are so high or low that they can cause heat-related or cold-related illness or injury to a person. Air temperature as well as other factors can contribute to creating an extreme temperature environment. Heat-related and cold-related illnesses and injuries can be fatal.

Good practice guidelines

This good practice guide provides practical advice on how to identify, control, and monitor the health and safety risks associated with working in extremely hot and extremely cold environments. It is for any PCBU (a person conducting a business or undertaking) who manages a workplace, or whose workers carry out work activities in environments that can be extremely hot or extremely cold.

It may also be useful for health and safety professionals who are providing extreme temperature risk assessments or monitoring for PCBUs.
