Engineering Controls
Engineering controls are measures that modify the workplace or equipment to reduce exposure to hazards, including heat. Examples include installing air conditioning, using fans to increase airflow, or placing barriers to block direct heat from the sun or hot machinery.
Example: Workers taking a break under a shade structure is an effective engineering control against direct heat exposure.
Air Conditioning and Ventilation
Air Conditioning
- Provides a cooler indoor environment, reducing the risk of heat stress for employees.
- Should be installed and properly maintained in work areas, break rooms, and any indoor spaces where heat may pose a risk.
Ventilation
- Enhances airflow and reduces heat accumulation in workspaces.
- Systems such as exhaust fans remove hot air and bring in cooler air, helping to lower temperatures and humidity levels.
By combining air conditioning and proper ventilation, workplaces can maintain safer, more comfortable conditions and minimize the risks associated with high temperatures.
