Summer is here, bringing intense heat and humidity with it. This means dangerous working conditions for many on the job.
AFT Maryland and the City Union of Baltimore (CUB), along with a coalition of labor unions, recently scored a victory for worker safety during the hot days of summer. Together, we worked for new regulations to protect workers from the increasing risk of heat-related illnesses on the job.
The Maryland Occupational Safety and Health (MOSH) division of the state’s Department of Labor (DLLR), finalized the new heat illness prevention rules with implementation to begin ahead of the 2025 summer season.
Under the new rules, employers must take specific actions when the heat index hits 80°F or higher. These include:
- Access to Water - Employers are required to provide at least 32 ounces of cool, drinkable water per employee per hour and to encourage frequent hydration breaks.
- Shade and Rest Breaks must be available and close to work areas.
- High Heat Procedures - When the heat index rises above 90°F – additional steps must be taken, including mandatory rest periods.
- Required Training for both employees and supervisors on the dangers of heat illness, how to recognize symptoms, and the steps to take in an emergency.
- Monitoring and Communication - Employers are expected to monitor workers for signs of heat stress using tools like buddy systems, radios, and phones.
- Written Heat Illness Prevention Plans - Every workplace must develop a written plan tailored to its specific conditions. The plan must be accessible to workers and include clear procedures for compliance with the new rules.
- Recordkeeping - Written plans and records of employee training must be maintained and available for inspection.
- Emergency Response Plans - Workplaces must have emergency procedures in place to respond to heat illness including immediate access to medical services.
The Department of Labor is currently doing outreach and education in both the public and private sectors to prepare for full compliance this summer.
