Summer brings longer days and warmer temperatures across Oregon, but it also increases the risk of heat-related illness for employees who work outdoors or in hot environments. Construction crews, landscapers, agricultural workers, warehouse employees, and manufacturing teams are especially vulnerable to heat stress.

At Elliott, Powell, Baden & Baker Insurance, we’ve worked with Oregon businesses for decades to help manage workplace risks and navigate workers’ compensation claims. Heat-related illnesses are largely preventable, but when they occur, they can lead to lost productivity, medical expenses, workers’ compensation claims, and even life-threatening emergencies.

Recognizing the Warning Signs

Heat-related illnesses can range from mild symptoms to medical emergencies.

Heat Exhaustion

Common symptoms include:

• Heavy sweating
• Fatigue and weakness
• Headache
• Dizziness
• Muscle cramps
• Nausea or vomiting
• Cool, clammy skin

Without treatment, heat exhaustion can progress to heat stroke.

Heat Stroke

Heat stroke is a medical emergency requiring immediate medical attention.

Signs include:

• Body temperature above 103°F
• Confusion or disorientation
• Loss of consciousness
• Seizures
• Hot, dry skin
• Rapid pulse

Call 911 immediately if heat stroke is suspected. Heat stroke can be fatal.

Oregon Heat Safety Requirements

Oregon OSHA has adopted permanent heat illness prevention rules that apply when the heat index reaches 80°F and require additional protections when temperatures exceed 90°F. Employers must provide adequate water, shade, training, and emergency planning.

At 80°F Heat Index and Above

Employers are required to provide:

• Sufficient drinking water (up to 32 ounces per hour per employee)
• Access to shade or cooling areas
• Employee training
• Emergency response procedures
• Acclimatization plans for new or returning workers

At 90°F Heat Index and Above

Additional protections are required, including paid cool-down breaks and employee monitoring. Oregon OSHA requires a minimum 10-minute shaded break every two hours. At higher temperatures, break requirements increase.

For example:

• 90–94°F: 10 minutes every two hours
• 95–99°F: 20 minutes every hour
• 100–104°F: 30 minutes every hour
• 105°F or above: 40 minutes every hour

Employers must also maintain effective communication with workers and have procedures in place to obtain emergency medical assistance.

Preventing Heat Illness

Simple preventive measures can dramatically reduce risk:

• Encourage employees to hydrate frequently.
• Schedule strenuous work earlier in the day.
• Rotate physically demanding tasks.
• Allow employees time to acclimate to hotter conditions.
• Train supervisors to recognize symptoms.
• Encourage workers to report concerns immediately.

How Insurance Plays a Role

Heat-related illnesses can result in workers’ compensation claims, lost productivity, and increased claim costs.

Workers’ compensation insurance may help cover:

• Medical expenses
• Hospitalization
• Lost wages
• Rehabilitation costs

Preventing injuries not only protects employees but can also help businesses manage claims experience and maintain more favorable workers’ compensation costs over time.

Heat-related illness is one of the most preventable workplace hazards facing Oregon employers. Understanding the warning signs, complying with Oregon OSHA requirements, and creating a culture of heat safety can help protect employees and reduce business interruptions.
