About this template
How it links to the standards
The equipment and controls this template asks you to record are governed by published standards that define what each item must withstand and how it is tested. These are the ones that apply most directly:
- EN ISO 11612 — heat and flame protective clothing
The full EN standards library covers every standard referenced across SafetyOrbit.

Humidity, radiant heat and workload combine with air temperature to create heat stress.
Frequently asked questions
What does the Heat Stress Assessment template cover?
An assessment for identifying and controlling heat stress risk, covering the factors that combine to create a heat-stress hazard for a specific task and environment.
What increases heat stress risk beyond just air temperature?
Humidity, radiant heat, physical workload and the PPE being worn all add to the effective heat load on a worker, which is why a proper assessment looks beyond the thermometer reading alone.
How does this template link to relevant standards?
Where it references protective equipment or a control measure, it points back to the relevant EN standard so you can confirm the correct level of protection.
Is this template a substitute for on-the-day monitoring?
No, it is a planning and control-selection tool used before or during a task – ongoing monitoring and worker welfare checks on hot days still need to happen separately.
