Nevada OSHA Heat Rules 2026: Workwear Planning for Las Vegas Contractors
Use current Nevada OSHA guidance and your job hazard analysis to evaluate clothing and PPE for heat exposure.
Nevada approved Regulation R131-24 in 2024. Nevada OSHA's official guidance says covered employers must perform a written job hazard analysis for occupational heat exposure. The analysis must be reviewed when a job task materially changes.

Start With Current Nevada OSHA Sources
Read the approved regulation and Nevada OSHA guidance. Check the Nevada OSHA home page for updates.
The official materials distinguish required actions from recommended practices. They also explain coverage, written safety program duties, training, emergency response, and climate-controlled exemptions.
Connect Apparel to the Job Hazard Analysis
Do not choose a summer uniform from temperature alone. Document the actual job and all required protection.
- Work conditions. Review air temperature, humidity, radiant and conductive heat, air movement, workload, and exposure duration.
- Protective system. Include required high-visibility, arc-rated, flame-resistant, chemical, cut, and other PPE.
- Garment documents. Compare product labels, fabric details, care instructions, and manufacturer data.
- Worker factors. Follow the employer's program for training, communication, acclimatization, monitoring, and emergency response.
Common heat-season categories to review: work shirts, custom polo shirts, and caps and hats.
Questions to Ask Before Ordering Workwear
- Which hazards and project rules apply to each role?
- Which garment classifications and manufacturer documents are required?
- How do fabric weight, construction, color, ventilation, fit, and layering affect the complete program?
- Will decoration add ink, thread, backing, heat, or covered area that needs manufacturer review?
- Are every product, size, substitution, price, and delivery term confirmed in writing?
Heat Planning With Hi-Vis and FR Requirements
Heat exposure does not cancel another identified hazard. If the employer requires high-visibility or arc-rated apparel, evaluate products within that approved category. See current hi-vis options, custom safety vests, and FR clothing.
Review the exact product with the employer, safety lead, and manufacturer. Do not infer a garment's class, arc rating, or suitability from color, fabric weight, or marketing language.
Decoration can affect a protective garment. Obtain written approval for thread, backing, ink, curing, size, and placement before production.
What Bighorn Can Put in a Quote
Bighorn can coordinate product options through selected production partners. A proposal can identify the exact garments, available product documents, decoration plan, quantities, pricing, and expected timing.
Availability, substitutions, freight, documentation, and production terms depend on the selected partner. Your employer and safety lead approve the final product. For crews outfitting a full season, see construction and trades apparel in Las Vegas or set up a company store for contractors.

What does the Nevada heat illness regulation require?
Nevada Regulation R131-24 requires covered employers to assess working conditions that may cause occupational heat illness. Covered employers must address identified hazards in their written safety program. Use current Nevada OSHA guidance for the complete requirements.
Does Nevada OSHA require a specific work shirt?
The regulation does not prescribe one universal shirt. Clothing and PPE are factors in the job hazard analysis. The employer selects controls and products for the actual task, environment, and other hazards.
Can lightweight clothing replace other required PPE?
No. Heat planning does not remove requirements identified for traffic, electrical, chemical, fall, or other hazards. The employer and safety lead must review the complete protective system.
Can Bighorn Threads certify heat-rule compliance?
No. Bighorn can quote apparel options and request available product documents. The employer remains responsible for its hazard analysis, safety program, training, controls, and product approval.
