Cal/OSHA 3395 checklist
A plain-English outdoor heat checklist for Cal/OSHA T8 CCR 3395: water, shade, heat wave, and 95 F high heat.
Cal/OSHA T8 CCR 3395 is the outdoor heat illness prevention standard. Employers owe potable water and cool-down rest at any temperature, shade that is present and open above 80 F, heat-wave awareness from 80 F, and high-heat procedures at 95 F in listed industries. This checklist is the operational list supervisors use on an action day, not a substitute for reading the rule.
Takeaways
- Run the outdoor checklist against a real worksite temperature reading.
- Say what changes at 80 F versus 95 F.
- Know which industries pick up high-heat procedures.
- Keep the signed log with the written heat illness prevention plan.

Frequently asked questions
- Is this checklist enough to be compliant? No. It is an operational aid aligned to T8 3395. Compliance still depends on your written plan, training, and how you run the site on the day.
- Do I need high-heat procedures at 90 F? No. High-heat procedures under 3395(e) start at 95 F for the listed industries. Water, shade, and heat-wave duties can already apply below that.
- Does landscaping get the agricultural cool-down? The mandatory ten-minute cool-down every two hours above 95 F is an agriculture provision. Landscaping still picks up the other high-heat procedures at 95 F.
