AB 414 — Summary (2025 session)

Status: Vetoed by the Governor (June 11, 2025)

Purpose

AB 414 would have expanded workplace written-safety program requirements for certain large “hybrid” facilities to address occupational exposure to poor air quality and specified gases (including greenhouse gases). The bill aimed to require employers to adopt monitoring and mitigation systems to protect employees working where indoor and outdoor conditions mix (e.g., through open loading docks).

Key provisions

  • Definition — “Large hybrid environment facility”: any facility (examples: distribution centers, convention centers) that is at least 10,000 square feet and where employees are exposed to outdoor elements for a majority of each shift (including via open loading docks/bay doors).
  • Applicability threshold: employers required to include the new provisions in their written safety program if they have more than 15 employees who work at such a facility.
  • Required program elements:
    • A system to mitigate employee exposure to greenhouse gases, other gases, or poor air quality consistent with applicable occupational safety and health standards (NRS 618.295).
    • A system for monitoring employees for signs of health effects from those exposures.
    • A requirement that vehicles loading or unloading on-site have engines turned off (exception: refrigerated units with independent motors may run refrigeration).
    • A designated person must, when employees are working, monitor air/gas levels in each work area at least every 4 hours and record readings in a logbook kept on-site and available on request.
    • If monitoring shows levels exceed applicable occupational standards, employers must use additional fans or forced ventilation to increase airflow (including through open docks/doors).
  • Definition of “greenhouse gas” clarified in amendment to include methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O), and fluorocarbons.
  • Amendments removed earlier heat/heat-illness provisions and deleted references to “fumes” for clarity.

Exemptions

The bill (as amended) exempted:
- Law enforcement, firefighting and emergency-response employees;
- Operations involved in solid waste management, disposal sites, recycling centers, or hazardous waste management;
- Tow companies/towing services;
- State agencies (added by later amendment).
Also, employers with 15 or fewer employees at a covered facility were excluded from the new requirements.

Who is affected

  • Employers operating large hybrid environment facilities with more than 15 employees (distribution centers, convention centers, large warehouses).
  • Employees who work in those facilities (potentially benefitting from increased monitoring and ventilation).
  • Exempted employers and small employers are not required to comply.

Procedural / implementation notes

  • The new elements were to be included in the employer’s written safety program, which under existing law must be implemented within 90 days after establishment.
  • Monitoring records (logbook) must be kept at the facility and made available on request.
  • Compliance is tied to occupational safety and health standards established under NRS 618.295.

Fiscal and other impacts

  • The bill carried a fiscal note: may have a fiscal impact on local government and the State and was identified as containing an unfunded mandate (Section 3).
  • Anticipated compliance costs for affected employers include monitoring equipment, staff time (monitoring/logging every 4 hours), ventilation upgrades, and policy/procedure development.

Legislative history (selected)

  • Introduced March 12, 2025; amended multiple times (removing heat provisions, defining greenhouse gases, adding exemptions, exempting state agencies).
  • Passed both houses in amended form; various reprints and committee amendments adopted.
  • Vetoed by the Governor on June 11, 2025.
