Summary
In short
- A thermal stress assessment is an assessment used in KnowHealth that assesses heat or cold stress risk from temperature, humidity, workload and clothing. It is built against ACGIH TLV, ISO 7243 and forms part of the Wellbeing and Mental Health programme.
- Run seasonally and when conditions change. Carried out by a hygienist or trained assessor.
- The template holds 52 fields across 6 sections.
- Scoring is risk band, where high is bad.
- ISO is international Organization for Standardization. A voluntary international standard. Widely adopted, often required by customers, and certifiable where a management system standard.
- It connects to the rest of the library: links Site, Job, Worker.
What it is
What it is
What is a thermal stress assessment?
A thermal stress assessment is an assessment used in KnowHealth that assesses heat or cold stress risk from temperature, humidity, workload and clothing. It is built against ACGIH TLV, ISO 7243 and forms part of the Wellbeing and Mental Health programme.
When is a thermal stress assessment completed?
A thermal stress assessment is completed when the task, area or population being assessed is new or has materially changed. Run seasonally and when conditions change.
When to use it
When to use it, and when not to
This assessment is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use it for
- The event or activity this assessment covers has occurred, or is about to
- A new record is needed; each one gets its own ID in the form THS-2026-000
- You are running the Wellbeing and Mental Health programme and this is one of its steps
- A linked record needs this one to exist: links site, job, worker
Not for
- Anything outside KnowHealth, which belongs in the workspace that owns that process

FAQ
Frequently asked questions
What is the thermal stress assessment template based on?+
It is built against ACGIH TLV, ISO 7243. ISO is international Organization for Standardization. A voluntary international standard. Widely adopted, often required by customers, and certifiable where a management system standard. ACGIH is american Conference of Governmental Industrial Hygienists. Publishes threshold limit values for chemical and physical agents. Guidance, but widely adopted into law.
What sections does the thermal stress assessment contain?+
There are 6 sections: header, environment, work and clothing, individual factors, controls, outcome. Together they hold 52 fields, 36 of which are required.
How often is a thermal stress assessment raised?+
A new record is raised when the task, area or population being assessed is new or has materially changed. Each one is given an ID in the form THS-2026-000, so it can be traced and referenced from other records.
Which programme does the thermal stress assessment belong to?+
It is part of Wellbeing and Mental Health. Psychosocial risk assessed the way physical risk is, with workload treated as a control.
How is a thermal stress assessment scored?+
Scoring is risk band. High is bad. Scores exist to make the form tell you something, not to produce a percentage for its own sake.
Can the thermal stress assessment template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to other templates come with it. Most teams install it as it is, run it for a cycle, then adjust.
The agents
What the agents do with it
The form is the easy part. Keeping it current, routing it to the right owner and holding the evidence together is the work that actually slips.
Holds the thermal stress assessment library against your registers, routes each record to its owner, and keeps the evidence trail together.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.
This template lives in KnowHealth — employee wellbeing. Exposure monitoring, health surveillance, case management and return to work.
