Oregon heat rules aim to protect workers as temperatures soar. Here’s what’s required

Temperatures soaring above 100 degrees through the weekend could put to the test worker protections enacted after a deadly 2021 heat wave. Here’s what Oregon OSHA’s rules say.

The agency says employers must provide at least four cups — a quarter gallon — of water per hour to workers outside. That water must also be under 77 degrees. Health experts say drinking water is the most important and effective way to combat heat and related illnesses.

Above 80 degrees — or 90 degrees for “rest” and “light” work — all workplaces must provide employees with shaded areas open to the air or with ventilation. The shaded areas should be as close as is practical and be able to accommodate the number of employees on rest, recovery or meal periods with room to sit.

In this heat wave’s temperatures, Oregon OSHA rules require workers be equipped to call for medical assistance and that employers ensure communication for employees working alone.

Employers must also provide breaks to prevent heat-related illness. Those breaks are counted as a work assignment.

Oregon OSHA says employers must provide annual training for employees on worksites that exceed 80 degrees on their compliance requirements, the danger of heat-related illness and best practices to avoid them.

Employers must also develop plans for acclimatization — allowing employees to adapt to working in conditions more than 80 degrees. This is especially important for newer workers. OSHA says almost half of heat-related deaths occur for workers on their first day. It also says more than 70% of heat-related deaths happen in a worker’s first week.

A spokesperson for Oregon OSHA said over email that the agency has issued more than 170 citations to employers violating worker protections for high heat since its rules went into effect — amounting more than $100,000 in penalties. The agency does not give advance notice of inspections.

Oregon OSHA violation penalties increased earlier this year. More information on key requirements for employers are available in English and Spanish.
