United StatesEuropean Parliament Committee Backs Motion on Work-Related Deaths, AI and Heat Risks
In May 2026, the European Parliament’s employment committee adopted a non-binding motion urging EU action to reduce work-related deaths, including new recognition of AI-driven and climate-related risks to occupational health and safety. While it creates no immediate legal obligations, it signals pressure for future EU initiatives on worker protection, stronger labour inspectorates, and cross-sector risk assessments, especially in high-risk sectors like construction, transport and agriculture.
European UnionColorado House Advances Extreme Temperatures Worker Protections Bill (HB26-1272) With Committee Amendments
Colorado has advanced HB26-1272, a bill directing the Department of Labor and Employment to collect data on temperature-related workplace injuries and to publish a statewide model prevention plan for extreme heat and cold, backed by a USD 63,382 appropriation. For employers this signals likely future statewide standards on heat- and cold-stress protections, but current obligations fall mainly on the labour department while the bill moves through the Senate.
United StatesNew Jersey Senate Bill S4137 Would Establish Occupational Heat-Illness Prevention Program
New Jersey lawmakers are advancing Senate Bill S4137 for the 2026–2027 session to create an Occupational Heat-Related Illness and Injury Prevention Program and require the labour department to set a statewide occupational heat-stress standard. If enacted, this framework would likely impose new heat-stress prevention and response requirements on employers in outdoor and high-heat workplaces, so businesses should monitor the bill’s progress and prepare for potential compliance planning once details emerge.
United StatesVirginia Enacts SB288 Requiring Workplace Heat Illness Prevention Standards
Virginia has enacted SB288 (Acts of Assembly Chapter 732), adding Code of Virginia § 40.1-44.2 to mandate heat illness prevention standards for indoor and outdoor workplaces, effective July 2026. Employers covered by Virginia OSHA should prepare for stringent heat stress controls, worker training, and formal prevention plans as the Board develops implementing regulations by May 2028.
United StatesNew Mexico EIB Postpones Hearing on Heat Illness and Injury Prevention Rule (11.5.7 NMAC)
New Mexico’s Environmental Improvement Board has postponed the public hearing on the state’s Heat Illness and Injury Prevention rule (11.5.7 NMAC, docket EIB 25-11 (R)), which had been scheduled for early May 2026. This postponement delays the rulemaking timeline for a statewide workplace heat standard, so employers and stakeholders should plan for continued uncertainty until a new hearing date is announced.
United StatesUS Senate Introduces S. 4427 To Bar Heat Injury And Illness Prevention Standard
US senators have introduced S. 4427, a bill that would bar the Department of Labor from finalising, implementing, or enforcing any proposed federal standard on heat injury and illness prevention. If passed, this could halt anticipated new heat-safety rules for workers, affecting how companies plan investments in heat exposure controls, training, and compliance programmes.
United StatesGermany (BAuA) Details ASR A5.1 Heat and UV Protection Duties for Outdoor Workplaces
In April 2026, Germany’s occupational safety authority highlighted how the 2025 Technical Rule ASR A5.1 should be applied to protect outdoor and semi-enclosed workplaces from heat, UV radiation, wind, rain and thunderstorms. Employers with outdoor staff in Germany should treat ASR A5.1 as the benchmark for ArbStättV compliance, revisiting risk assessments, work organisation and protective measures now to manage rising extreme-weather risks and avoid future liability.
GermanySlovenian Labour Ministry Issues Heatwave Safety Guide for Outdoor Work
In April 2026 Slovenia’s labour ministry published a comprehensive national guide translating existing occupational safety law into concrete steps for managing heat stress for outdoor workers.
