Key idea
Why action levels are useful, why they are not universal, and how policies vary by setting.

Thresholds need context

Sports associations, employers, and other organizations may use different WBGT bands. Those policies account for the work or exercise being done, equipment, and how prepared people are for heat.

Use the applicable policy

Check whether your organization requires a specific instrument, measurement location, temperature unit, or response schedule. Use those instructions when planning breaks, modifying activity, or stopping it.

Keep watching conditions

A threshold is a decision aid, not a guarantee of safety. Reassess when weather, exposure, workload, or a person’s condition changes.
