According to an online poll from the Memphis Business Journal, hvac repair is ranked among one of the worst jobs to have during a heat wave.

After all, when a client’s air conditioning breaks during intolerable heat more than temperatures rise – tempers flare and demand outweighs supply.

And repairs aren’t limited to air conditioning. During extreme heat everything is running at full tilt, meaning refrigeration units also are at risk of failure.

Aside from the elevated workload, hvacr contractors need to manage employee health.

Recognizing the signs of heat-related illnesses can ensure employees are in top form to help your business maintain its cool during the busy season. Heat exhaustion, a major concern during sweltering summer months, can occur after excessive physical exertion. Contractors are especially susceptible because their jobs require physical labor in poor conditions.

According to the Mayo Clinic, heat exhaustion can range in severity from mild heat cramps to heat exhaustion to potentially life-threatening heatstroke.

Signs and symptoms resemble those of shock and may include:

• Feeling faint

• Nausea

• Heavy sweating

• Ashen appearance

• Rapid, weak heartbeat

• Low blood pressure

• Cool, moist skin

• Low-grade fever

If you suspect heat exhaustion, the Mayo Clinic suggests:

• Get the person out of the sun and into a shady or air-conditioned location.

• Lay the person down and elevate the legs and feet slightly.

• Loosen or remove the person's clothing.

• Have the person drink cool water, not iced, or a sports drink containing electrolytes.

• Cool the person by spraying or sponging him with cool water and fanning.

• Monitor the person carefully. Heat exhaustion can quickly become heatstroke. If fever greater than 102 F, fainting, confusion or seizures occur, dial 911 or call for emergency medical assistance.

Share the signs, symptoms and suggestions with your employees, and make sure workers know that their health is important to you. Doing so will help your business grow.
