Colorado has a specific heat illness regulation: 7 CCR 1101-1 Rule 6.12 (COMPS Order). Here is what CDLE/COSHA requires, what gets cited, and how to close compliance gaps before an inspection.
Colorado's heat protections are incorporated into the Colorado Overtime and Minimum Pay Standards (COMPS) Order. Covers private sector employees. Combined federal OSHA General Duty Clause applies for OSHA-specific enforcement. Enforcement active in Denver metro, Front Range, and high-desert areas.
"Colorado's 7 CCR 1101-1 Rule 6.12 (COMPS Order) applies to all outdoor places of employment — including commercial pressure washing operations. Employers must provide water, shade, rest periods, acclimatization, training, and a written Heat Illness Prevention Plan. Each element is independently citable." Colorado Department of Labor and Employment (CDLE)
These six requirements form the core compliance framework. CDLE/COSHA inspectors verify each independently. Missing any single element is sufficient grounds for a citation — even if the other five are in place.
| Requirement | What's Required in Colorado |
|---|---|
| Water | Cool drinking water accessible at no cost; employer responsible for supply during outdoor work |
| Shade | Reasonable access to shade or cool area; required when heat index ≥91°F under federal OSHA guidance |
| Rest Breaks | Rest breaks in cool or shaded areas; frequency increases with heat index |
| Acclimatization | New employee adjustment protocols required; reduced workload during first week |
| Training | Heat illness recognition, prevention, and first aid; supervisor certification recommended |
| Written Plan | Written emergency response and heat illness prevention procedures required under federal OSHA General Duty Clause |
COSHA and federal OSHA Region 8 (Denver) cited 31 outdoor services employers for heat violations in 2024. Colorado's high-altitude UV exposure combined with heat creates accelerated dehydration risk that inspectors specifically cite for inadequate water provisions.
Heat illness violations are among the most straightforward citations in OSHA enforcement: the standard is clear, the failure is visible (no shade, empty water jugs, no written plan), and the injury creates automatic scrutiny. Pressure washing contractors are a common target because outdoor work is inherently high-exposure and crew sizes are often small enough that written plans are overlooked.
A written Heat Illness Prevention Plan creates the paper trail that separates a correctable general violation from a serious or willful citation. In Colorado, employers with a written plan who experience a heat illness incident face substantially lower penalty exposure than those without one.

Get Safety Pack →Colorado uses a combination of state-level COMPS Order requirements and federal OSHA's General Duty Clause for heat illness enforcement. While not as prescriptive as California's §3395, outdoor employers including pressure washing contractors are fully subject to enforcement.
OSHA's Heat Illness Prevention guidance (used in Colorado enforcement) identifies 91°F heat index as requiring shade access and water, and 103°F as requiring mandatory rest and close employee monitoring.
Yes. Under federal OSHA's General Duty Clause (applicable in Colorado), employers who fail to maintain written heat illness procedures may be cited when an employee suffers heat-related illness. A written HIPP is the primary documentation defense.
Federal OSHA penalties apply: up to $16,550 per serious violation, up to $165,514 per willful or repeat violation. Colorado state penalties under CDLE are $1,000–$10,000 per violation.
