Deploy Our IoT Solutions to Meet New Heat Safety Regulations
Extreme heat doesn’t just pose a threat outdoors; it’s increasingly recognized as a serious indoor workplace hazard. For example, new heat illness prevention regulations in California and Maryland are raising the bar for workplace safety. Monnit’s IoT technology helps employers stay compliant, protect employees, and streamline monitoring.
California’s Indoor Heat Regulation: A Quick Overview
As of July 23, 2024, the California Heat Illness Prevention in Indoor Places of Employment regulation is officially in effect. Prompted by Senate Bill 1167, this regulation expands Cal/OSHA’s rules for preventing heat illness in indoor environments.
The rule applies to any indoor workspace where the temperature reaches 82°F or higher. Employers must implement a comprehensive Indoor Heat Illness Prevention Plan written in English and any language most employees understand. It should outline:
Procedures for measuring and recording temperature or the heat index.
Access to water and cool-down areas.
Acclimatization protocols for new or returning employees.
Emergency response actions for heat illness.
Training for employees and supervisors on heat-related risks and safety procedures.
At 87°F or higher, or in situations involving heat-retentive clothing or radiant heat sources, stricter rules apply. These include:
Mandatory recordkeeping for 12 months of temperature and heat index data.
Engineering controls, such as ventilation and cooling systems, where feasible.
Personal protective equipment if other controls are insufficient.
Maryland’s Heat Stress Illness Prevention Standard
Maryland Occupational Safety and Health (MOSH) has also taken a proactive stance. Covered employers must comply with the new heat stress standards whenever employees work where the heat index reaches 80°F or higher.
Maryland’s rules apply to indoor and outdoor worksites unless the site is ventilated and keeps the temperature below 80°F. The law applies to various employers, except for emergency operations, brief incidental exposures, and mechanically ventilated environments.
Employers must:
Monitor the temperature and humidity throughout the shift using approved methods.
Provide an accessible written heat illness prevention plan.
Offer cool, clean drinking water and sufficient shaded or climate-controlled rest areas.
Train employees about heat risks and emergency responses.
Establish rest break schedules according to heat index levels:
A 10-minute break every 2 hours at 90–99°F
A 15-minute break every hour above 100°F
Implement a written emergency response plan, including communication, transport, and first-aid procedures.
