State safety officials are reminding employers to take specific steps to protect outdoor workers as wildfire smoke and heat hazards increase across the region.
When fine particulate pollution (PM2.5) exceeds 250 micrograms per cubic meter, employers are required to provide a designated clean-air area for employees experiencing severe symptoms from smoke exposure.
Workers who feel ill from workplace smoke should immediately inform a supervisor, monitor their conditions for worsening symptoms and seek a medical evaluation at a healthcare provider or emergency room. Healthcare professionals can assist injured workers in filing worker's compensation claims if the illness is tied to job exposure.
Preparation for extreme heat is equally vital before temperatures rise. Workplace guidelines require supervisors and crew members to recognize early signs of heat-related illness, particularly heat stroke and understand emergency response procedures.
To help businesses stay compliant, the Washington Department of Labor and Industries offers free Division of Occupational Safety and Health consultations to assist in developing customized safety plans and training programs.
