- Confusion, hot dry skin, or fainting is an emergency. Call for help.
When to use it
Use it on hot days, in the first days of a heat wave, and for new or returning workers.
Review it with the crew before the work starts, change anything that doesn't match how you'll do the job, and update it when the method, the equipment, or the site changes.
