Ohio summers can bring dangerously high temperatures, and for many workers, the heat is more than just uncomfortable. Although construction workers and other outdoor employees often face the greatest exposure, employees working in warehouses, factories, commercial kitchens, and other facilities without adequate cooling may also be at risk of dangerous workplace heat.
In both indoor and outdoor work environments, prolonged heat exposure can lead to serious illnesses that can develop quickly and, in some cases, become life-threatening. The Bureau of Labor Statistics reports that 479 workers in the United States died from occupational heat exposure between 2011 and 2022.
If your claim is disputed or your employer questions whether your illness was work-related, an experienced workers’ compensation attorney can help protect your rights.
Heat-Related Illnesses Every Ohio Worker Should Know
Working in extreme heat can affect the body in several ways. Some conditions develop gradually, while others can become life-threatening within minutes if they are not recognized and treated promptly.
Heat Exhaustion
Heat exhaustion occurs when the body loses excessive amounts of water and salt through heavy sweating. Workers may experience:
- Excessive sweating
- Weakness or fatigue
- Dizziness
- Headache
- Nausea or vomiting
- Muscle cramps
Without prompt treatment, heat exhaustion can progress to heat stroke.
Heat Stroke
Heat stroke is the most severe form of heat-related illness and requires immediate emergency medical care.
When the body can no longer regulate its temperature, core body temperature rises rapidly, potentially causing:
- Brain damage
- Organ failure
- Permanent disability
- Death
Even workers who survive heat stroke may experience long-term neurological or cardiovascular complications.
Dehydration and Other Heat-Related Conditions
Extreme heat can also cause:
- Severe dehydration
- Heat cramps
- Heat syncope (heat-related fainting)
- Rhabdomyolysis (muscle breakdown)
Although these conditions may appear less serious initially, they often indicate that the body is struggling to regulate its temperature and may signal the development of more severe illness.
In some cases, extreme heat may also aggravate underlying medical conditions, such as heart disease, kidney disease, asthma, or diabetes, particularly during physically demanding work.
Warning Signs You Should Never Ignore
Heat illness can worsen rapidly, making early recognition critical. Workers and supervisors should watch for symptoms such as:
- Soaking sweat or a sudden stop in sweating
- Dizziness or lightheadedness
- Weakness or unusual fatigue
- Headache
- Muscle cramps
- Nausea or vomiting
- Rapid heartbeat
- Hot, flushed, or dry skin
- Confusion or disorientation
- Slurred speech
- Fainting
Confusion, loss of consciousness, or hot, dry skin may indicate heat stroke. Continuing to work despite symptoms can allow a relatively mild heat-related illness to progress into a medical emergency. Call 911 immediately, move the worker to a cooler location, and begin cooling measures while waiting for emergency medical personnel.
Which Workers Face the Greatest Risk?
Although anyone working in high temperatures can develop heat-related illness, certain occupations face greater exposure.
Workers at increased risk include:
- Construction workers
- Roofers
- Road construction crews
- Agricultural and farm workers
- Landscaping employees
- Warehouse workers in facilities without adequate climate control
- Manufacturing employees working near furnaces, ovens, or other heat-producing equipment
New employees, workers returning after time away, and individuals performing strenuous physical labor may face an even greater risk because their bodies have not yet acclimated to working in extreme heat.
Employers Have a Responsibility to Help Prevent Heat Illness
The Occupational Safety and Health Administration (OSHA) recognizes excessive workplace heat as a serious occupational hazard.
Although OSHA has not adopted a specific federal heat standard, employers are still required under the Occupational Safety and Health Act’s General Duty Clause to provide a workplace free from recognized hazards that are likely to cause death or serious physical harm, including excessive heat.
To help reduce the risk of heat-related illnesses, the agency encourages employers to implement measures such as:
- Providing plenty of cool drinking water
- Allowing regular rest breaks
- Offering shaded or cooled recovery areas
- Adjusting work schedules during periods of extreme heat
- Gradually acclimating new workers to hot conditions
- Training employees to recognize heat-related illness
The Ohio Department of Health encourages Ohioans to take precautions during periods of extreme heat. It reminds residents that heat waves can pose serious health risks, particularly for people who work outdoors or have underlying health conditions.
When employers ignore these precautions or pressure employees to continue working despite dangerous conditions, workers may suffer preventable injuries and illnesses.
Can You Receive Workers’ Compensation for a Heat-Related Illness in Ohio?
In many cases, yes. Ohio workers’ compensation may cover heat-related illnesses that arise out of and in the course of employment. Depending on the circumstances, eligible workers may receive benefits for necessary medical treatment, wage replacement if they miss work, and other benefits available under Ohio’s workers’ compensation system.
However, obtaining benefits is not always straightforward. Employers and insurance companies may dispute whether the illness was actually caused by workplace heat exposure, making prompt reporting, medical treatment, and thorough documentation important.
Why Heat-Related Workers’ Compensation Claims Can Be Difficult
Unlike a fall or machinery accident, heat-related illnesses often develop gradually over several hours. That can make it more challenging to prove a workers’ compensation claim.
Employers or insurance companies may argue that symptoms were caused by:
- A pre-existing medical condition
- Personal health issues
- Dehydration unrelated to work
- Activities outside the workplace
- Illness that developed after work hours
Because fatigue, headaches, dizziness, and nausea can have many possible causes, insurers sometimes dispute whether the illness actually arose from workplace heat exposure.
Medical records, witness statements, and documentation of workplace conditions often become critical evidence in establishing that a heat-related illness occurred on the job.
Protect Your Health and Your Workers’ Compensation Claim
If you begin experiencing symptoms of heat illness while working, taking immediate action can protect both your health and any future workers’ compensation claim.
If possible:
- Report your symptoms to a supervisor immediately.
- Request that the incident be documented.
- Seek medical treatment as soon as possible and tell your healthcare provider that the illness occurred while working.
- Document workplace conditions, including the temperature, humidity, availability of water, shade, or cooling areas, and the type of work you were performing.
- Take photographs if it is safe to do so.
- Collect names and contact information for coworkers who witnessed your symptoms or the working conditions.
Prompt reporting and thorough documentation can make it easier to establish that your illness was related to your job.
