8 CCR 3396: 4 First-Day Checks to Expect in Cal/OSHA Indoor Heat Inspections

Frequently Asked Questions

What documents should be ready if Cal/OSHA arrives for an indoor heat inspection?

Have your written indoor heat illness prevention procedures, training records, monitoring logs, hazard assessments, corrective-action records, emergency procedures, and related injury and illness records ready. Inspectors will compare those documents to what is actually happening on the floor.

Will Cal/OSHA only look at heat conditions during the inspection?

Not necessarily. If inspectors see broader issues during the walkthrough, they may also look at related Title 8 topics such as your Injury and Illness Prevention Program, drinking water access, PPE, ventilation, housekeeping, and recordkeeping.

What do inspectors usually look for on the plant floor under the indoor heat rule?

They typically look at hotter indoor zones, how you monitor those areas, whether water and cool-down measures are accessible, and whether ventilation or other controls are working. They also pay attention to process heat, work pace, overtime, and PPE that may increase heat strain.

Why are employee and supervisor interviews so important in a Cal/OSHA heat inspection?

Interviews show whether the written program is actually understood and used. If supervisors cannot explain response steps or employees do not know symptoms and reporting procedures, that can quickly expose implementation gaps.

What is the most common written-program problem with indoor heat compliance?

A common problem is a mismatch between the written program and real operations. Examples include unclear monitoring responsibilities, vague emergency steps, incomplete training, and procedures copied from outdoor heat plans without addressing indoor process heat.
