The National Weather Service has issued a Heat Advisory for the Willamette Valley. Temperatures on Tuesday and Wednesday could reach 98 degrees. It's important to drink plenty of fluids, stay in a cool place, and out of the sun. Weather this hot can lead to heat-related illnesses. It's possible smoke from wildfires could keep temperatures slightly cooler.
Under Oregon’s heat illness prevention rule, employers must implement protections, including adequate water, rest, shade, acclimatization (gradual adaptation to working in the heat), communication and training, and emergency plans. The rule applies to workplaces whenever an employee is working and the heat index equals or exceeds 80 degrees Fahrenheit. More protective measures apply when the heat index exceeds 90 degrees Fahrenheit.
Oregon’s wildfire smoke rule applies to employers whose employees are or will be exposed to hazardous levels of wildfire smoke. The harmful chemicals and tiny particles in wildfire smoke can make anyone sick. The tiny particles of most concern is the particulate matter with a diameter in micrometers of 2.5 or less, commonly referred to as PM2.5.
The rule’s protective measures include assessment and monitoring of air quality where workers are exposed; provision and documentation of employee training; implementation of two-way communication; use of engineering and administrative controls, such as relocation of workers to enclosed buildings or to outdoor locations where air quality is better, and work schedule changes to reduce exposures; and use of National Institute for Occupational Safety and Health (NIOSH)-approved filtering facepiece respirators.
