With excessively hot temperatures in the state this week, employers and workers should take precautions to prevent heat stress for anyone working outdoors, the Department of Labor and Industries (L&I) said Monday.

L&I said workers should drink plenty of water, even when not thirsty, take regular breaks, wear light clothing and adjust to the pace of the work, among other things. A worker who begins feeling ill should stop work immediately and take steps to cool down.

“We’ve seen the temperature jump significantly in just the past two days — from the mid-70s to 90 and even 100 degrees in some parts of the state — so workers may not be adapted to the hot weather,” said Steve Cant, L&I’s assistant director for safety and health. “Heat stress is a serious health issue and can quickly escalate to heat stroke, which can cause death. Everyone who works outdoors in hot weather needs to take precautions.”

To protect yourself and co-workers from heat stress while working outside in hot weather:

— Drink plenty of water, even when not thirsty. Sip small amounts often.

— Try to do the heaviest work during the cooler parts of the day.

— Adjusting to the heat takes time; start slower and work up to your normal pace.

— Wear light, loose-fitting, light-colored breathable clothing such as cotton, and a hat.

— Take regular breaks in the shade.

— Avoid alcohol or drinks with caffeine before or during work.

— Watch co-workers for signs of heat exhaustion or heat stroke.

— If you start feeling symptoms (lightheaded, headache, nausea, dizziness, etc.), stop what you are doing immediately and take steps to cool down. Tell a supervisor.

If you think someone is suffering heat stroke, get medical help immediately by calling 911. Some of the signs of heat stroke include no sweating; red or flushed, hot dry skin; rapid pulse; headache; blurred vision; dizziness or fainting; difficulty breathing; pinpoint pupils; unusual behavior; convulsions; and collapse.

L&I adopted an emergency rule this year that requires employers with outdoor workers to have a safety plan in place to protect workers from heat-related illness during hot weather. Additionally, other rules require employers to provide drinking water and first-aid training.
