Nevada's heat framework.

Hazard-based

Risk-driven trigger

Nevada's rule uses a hazard assessment rather than a single heat-index threshold. Employers identify risk based on conditions, work intensity, and worker factors.

Indoor + outdoor

Full coverage

Covers any workplace where heat exposure is reasonably anticipated, including non-AC Las Vegas warehouses and outdoor construction.

Written plan

HIPP required

Covered employers must maintain a written heat illness prevention plan including training, water, cool-down, acclimatization, and emergency response.

2024

Effective

Adopted in 2024. Enforcement focus on construction, agriculture, hospitality, and warehousing during summer.

What the rule actually requires

Nevada, tier by tier.

Nevada is different: there is no single thermometer number. A written hazard assessment sets your trigger, which means the assessment itself is the compliance document.

Assess

Step one

Written job hazard analysis for heat exposure
Findings drive the written prevention plan

Control

Step two

Potable water provided
Cool-down area available
Rest breaks matched to the assessed risk

Sustain

Step three

Worker and supervisor training
Acclimatization for new and returning workers
Emergency response procedures

Where cooling vests fit

Built for Nevada's 110°F+ summer reality.

Las Vegas, Henderson, and Reno all exceed 110°F regularly in summer. Active cooling vests are supplemental PPE that extend the safe productive window when ambient heat alone breaks the work-rest cycle.

FAQ

Nevada heat standard: employer FAQ.

What is the Nevada heat standard?

Nevada OSHA adopted a heat illness regulation in 2024 that requires employers with significant heat exposure to perform a hazard assessment and implement a written heat illness prevention plan. The rule covers both indoor and outdoor work environments where heat exposure is reasonably anticipated.

What does Nevada's heat illness plan require?

A written plan including hazard assessment, water provisions, cool-down/shade areas, acclimatization protocols, employee and supervisor training, and emergency response procedures.

Does Nevada's rule cover indoor warehouses?

Yes. The Nevada heat rule applies to indoor environments where heat exposure is reasonably anticipated, including Las Vegas warehouses, distribution centers, and manufacturing facilities, particularly during summer when ambient temperatures regularly exceed 110°F.

What industries are most affected by Nevada's heat rule?

Construction, hospitality services with outdoor exposure, agriculture, utilities, mining, warehousing, and any industry operating in Las Vegas, Henderson, Reno, or other Nevada metros during summer.

Do cooling vests count for Nevada heat compliance?

Yes. Active cooling vests are supplemental PPE that support a Nevada heat illness prevention plan. They don't replace required water, shade, and rest provisions, but they extend safe productive time during the extreme-heat windows common to Nevada summers. See our cooling vest comparison.
