Nevada has a specific heat illness regulation: NAC 618.538 + Nevada OSHA Heat Standard. Here is what Nevada OSHA requires, what gets cited, and how to close compliance gaps before an inspection.
Nevada summers regularly exceed 110°F in Las Vegas and Reno areas. Nevada OSHA runs active summer enforcement campaigns. Pressure washing contractors working in parking structures, commercial lots, and exterior surfaces face high citation risk May–September.
"Nevada's NAC 618.538 + Nevada OSHA Heat Standard 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." Nevada Occupational Safety and Health Administration (Nevada OSHA)
These six requirements form the core compliance framework. Nevada OSHA 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 Nevada |
|---|---|
| Water | Potable water close to work area; min. 1 quart per hour per employee in extreme heat |
| Shade | Shade accessible at all times when ≥95°F; outdoor workers may not be denied shade access |
| Rest Breaks | Rest in shade allowed on request; preventive cool-down periods required in extreme heat (≥103°F) |
| Acclimatization | Acclimatization program required for all new employees; monitoring during first 7 days |
| Training | Heat illness prevention training before first outdoor work assignment; supervisor training required |
| Written Plan | Written plan required with site-specific procedures; must reflect Nevada's extreme heat conditions |
Nevada OSHA's summer enforcement sweeps target Las Vegas Valley and Reno-area contractors. In June 2024, a commercial exterior cleaning contractor was cited $14,200 for inadequate shade and failure to maintain written acclimatization procedures during 108°F conditions.
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 Nevada, employers with a written plan who experience a heat illness incident face substantially lower penalty exposure than those without one.

Get Safety Pack →Yes. Nevada operates its own OSHA program and has enacted stricter heat protections than federal OSHA's General Duty Clause guidance. Nevada OSHA has specific shade, water, rest, and written plan requirements that go beyond federal minimums.
Any heat illness resulting in hospitalization, medical treatment beyond first aid, or lost work time triggers a Nevada OSHA incident investigation. Employers without a written HIPP face automatic serious violations plus any additional citations for root-cause failures.
Yes. Nevada OSHA requires written training records showing who was trained, when, and what was covered. Records must be available for inspection. Oral training without documentation is insufficient.
Serious violations carry up to $15,625 per violation. Willful or repeat violations reach $156,259 per violation. Nevada's summer enforcement campaigns in 2024 resulted in over $1.2M in heat-related penalties statewide.
