At a glance

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.

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.

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

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?
