How to Stay On Top of OSHA Heat-Related Illness Prevention Measures

Heat is one of the most dangerous hazards your crew can face. And it’s also one of the most underestimated. OSHA reports that 50-70% of heat-related deaths occur in the first few days on the job before a worker’s body has had the time to adjust to the heat.

A serious heat-related incident can mean lost work hours, high medical costs, and, depending on the severity, a workers’ comp claim that affects your coverage for years to come.

As summer temperatures continue to break record highs, protecting workers from heat illness isn’t just an OSHA requirement. It’s a must, especially for businesses in states with extreme heat. Here’s what you need to know.

Occupational Safety and Health Act Heat Injury & Illness Protection

In accordance with the Occupational Safety and Health Act General Duty Clause, employers are legally required to keep all workplaces they control free of safety and health hazards. This includes OSHA heat hazards, so it's essential that you take preventative measures if your workers are exposed to heat… both outdoors and indoors.

It’s important to note that 22 states have their own OSHA-approved standards and offer numerous industry- and location-specific resources for business owners on preventing heat-related illness in the workplace.

If you operate across multiple states, keeping track of what applies where can get complicated fast. A workers’ comp and payroll provider that works across state lines can help you stay on top of it.

OSHA Heat-Related Illness & Injury Overview

Heat-related illnesses and injuries, as defined by OSHA, include:

• Heat stroke
• Heat exhaustion
• Heat cramps
• Heat rash

Understanding the differences between these conditions isn't just about workplace compliance. It can literally save a life. Here is a breakdown of what each condition looks like, along with OSHA’s recommended response.

Heat Stroke

Heat stroke is the most severe heat-related illness, occurring when the body can no longer regulate temperature, causing a rapid rise to dangerous levels within minutes. It can cause confusion, altered mental state, slurred speech, unconsciousness, and more. If you suspect heat stroke, call 911 immediately. Then, move the worker to a cooler area and cool them quickly until medical help arrives.

Heat Exhaustion

Heat exhaustion results from excessive loss of water and salt, often through heavy sweating. Symptoms include heavy sweating, cold, clammy skin, a fast, weak pulse, nausea, dizziness, weakness, headache, or irritability. Unlike heat stroke, a person with heat exhaustion remains alert and continues sweating.

Anyone showing signs of heat exhaustion should be moved to a shaded or air-conditioned area, offered water, have clothing loosened, and have cool compresses applied. If symptoms worsen or persist beyond an hour, seek medical attention.

Heat Cramps & Heat Rash

Heat cramps affect workers who sweat heavily during strenuous activity, depleting salt and moisture, causing painful muscle spasms. Workers with muscle pain or spasms in the abdomen, arms, or legs should stop activity and rest in a cool place. Employers should provide water or electrolyte drinks, and workers should not return until cramps subside, as this may signal heat exhaustion.

Heat rash is a skin irritation caused by excessive sweating in hot, humid weather, often due to clogged pores that trap sweat. It appears as small red pimples or blisters on the neck, upper chest, groin, or elbows. OSHA advises keeping the rash dry, moving the worker to a cooler area, and avoiding tight clothing or ointments to prevent worsening.

Heat-Related Illness In High-Risk Industries

Many workers operate in areas that can be exposed to high temperatures, both indoors and out. Some examples of industries that may be at greater risk include:

• Construction
• Agriculture
• Landscaping
• Mail delivery
• Firefighting
• Iron and steel mills
• Food service
• Electrical & other utilities
• Warehouses

When a worker has symptoms of a heat-related illness, it’s not just a health emergency. It’s a workers’ comp claim. And that claim follows your business well past the day the event occurred.

Here’s what one heat-related incident can cost your business:

• Medical care for the injured worker
• Lost productivity while they recover
• Higher coverage payments down the road, since claims affect your rates
• Possible OSHA penalties if you weren’t compliant

That’s why prevention isn’t just the right thing to do. It protects your bottom line. And when an incident does happen, dedicated claims administration ensures your claims are handled fast and managed correctly. That way, a single bad day won't become a long-term cost.

How to Recognize the Signs & Symptoms of Heat Illness

Knowing the signs of heat-related illnesses can help you take action and ensure your workers get the treatment they need.

Signs and symptoms include:

• Thirst
• Heavy sweating
• Hot, dry skin
• Elevated body temperature
• Dizziness
• Weakness
• Headache
• Nausea
• Decreased urine output

For serious symptoms such as confusion, fainting, seizures, loss of consciousness, or hot, dry skin, call emergency services immediately and follow your workplace emergency response procedures. These symptoms may indicate heat stroke, which can be life-threatening and requires prompt medical attention.

For less severe symptoms, move the worker to a cooler area, encourage them to drink water if they are alert and able, and continue monitoring them. Seek medical care if symptoms worsen or do not improve quickly.

When a heat-related illness strikes, the absolute priority is your worker's health and well-being. Fast, responsive claims handling ensures your injured team member receives immediate, seamless access to the medical care needed to recover.

By letting dedicated claims support manage the complex administrative process from start to finish, you protect your employee first while gaining the peace of mind to focus on running your business and keeping the rest of your crew safe.

How to Craft a Prevention Plan

When workers are exposed to high temperatures, business owners need to create a plan to prevent heat illness, similar to their overall workplace safety plan.

To build an effective strategy tailored to your specific job site, your plan should address active hazard monitoring, proper adjustment periods for employees, and immediate access to resources.

Every effective heat illness prevention plan should include the following core components:

Track the Heat Index

Begin by understanding heat hazards and the heat index. Monitoring the heat index is essential because it details the baseline temperature, the relative humidity, and exactly how the temperature actually feels based on those two factors combined. Fortunately, OSHA has an app that can track the heat index for you.

Ease Employees Into Hotter Environments

According to the National Institute for Occupational Safety and Health (NIOSH), employers can help reduce heat stress risks by training workers before they begin work in extreme temperatures and training supervisors to use the appropriate acclimatization practices.

OSHA recommendations include gradually increasing workers' time in hot conditions over a 7- to 14-day period, with supervision, until workers become acclimated.

Provide Hydration

Consistently providing water, rest, and shade for your workers can significantly reduce the risk of heat illness. Cool water should always be available for workers, though that's only the beginning. If you have workers who plan to spend more than two hours in the heat, you will need to provide them with electrolyte-rich drinks as well.

Provide Rest & Shade

Rest and shade can be provided to your workers simultaneously. If high heat conditions are prevalent at the worksite, you will need to require workers to take breaks. The frequency of these breaks depends on the severity of the heat. Breaks should be taken in the shade at the very least, but air-conditioned buildings or a tent with fans are preferable.

Keep Your Workers Covered

While setting up these workplace safety protocols is a vital daily practice, managing all of the moving parts can be a challenge. Building a plan from scratch takes time most owners don’t have, and getting it wrong can leave you exposed. Resources like safety and risk management programs can do the heavy lifting for you: building your OSHA heat illness prevention plan, training your crew, and keeping it current as the rules change.

By committing to OSHA heat illness prevention measures, you can create a safe working environment that's good for your employees and legally compliant with regulations. Get in touch with our team to make sure you're staying compliant and keeping your people safe.
