Oregon high heat requirements 90 degrees
Oregon OAR 437-002-0156 rest-break schedule from heat index 90 F through 105 F.
Oregon does not use a California-style named high-heat procedure list. From heat index 90 F, OAR 437-002-0156 steps up paid heat illness prevention rest under the simplified table: 10 minutes every two hours at 90 F, then 20, 30, and 40 minutes per hour at 95, 100, and 105 F. Water, shade or cool-down area, and the written plan already apply from heat index 80 F.
Takeaways
- Read heat index, not plain temperature, for Oregon rest minutes.
- State the rest owed at 90, 95, 100, and 105 F.
- Document whether you use the simplified table, an employer-designed schedule, or NIOSH.
- Keep rest breaks on the signed action-day log.

Frequently asked questions
- Does Oregon high heat start at 90 F air temperature? No. Use heat index. A dry 90 F day may sit below the heat-index trigger that starts the rest table.
- Are the rest minutes paid? Oregon treats heat illness prevention rest under the rule as required rest. Keep it on the clock and on the log.
- Can I design my own rest schedule? Yes, if it is at least as protective as the simplified table, or you follow the NIOSH option. Document which path you chose.
