It is a measurement.

The photograph is the surface.
The body is the reading underneath.
02 | Evidence — the shift
Heat is not an event. It is an accumulation.

06:10 — looks fine

By the time failure is visible,
the damage has already begun.
03 | Evidence → Implementation

Same field. Two men.

Same site. Same season. Same policy on paper.

WORKER A
Protection did not reach him.

What differed was whether
protection reached the worker.
04 | Implementation

What we changed.

Cooling rest. Hydration. Access to safe and sanitary restrooms.
Built into schedules, with supervision that follows through.

Measure
See the thermal reality of the worksite and the worker.
Build it in
Turn evidence into a working day that protects people.
Follow through
Make implementation visible, accountable, and durable.

06 | Independent

LIN is the independent evidence and implementation partner for workforce protection in extreme heat.

Field tested. Peer reviewed. Built to change practice.
