California’s Heat Illness Prevention Standard (GISO 3395) requires that employers:

Provide plenty of cool, fresh water.

Provide a shaded area for workers to cool down.

Give workers a period of time to get used to the heat, especially during a heat wave or for new workers. This is known as "acclimatization."

Train workers about heat illness and how to prevent it.

Prepare an emergency heat plan and train workers on steps to take if someone gets sick.

Heat illness can be prevented!

"As employers we have to train our employees about heat illness, what we're doing on our worksite to prevent it, and how to respond in an emergency. It's worth it in the end to make sure everyone is well-prepared"
