HVAC technicians are frequently called on to fix or install HVAC equipment in the summer heat. It’s important to stay safe when working in soaring temperatures, which could put outdoor workers at risk of dehydration, heat stroke and other problems. While employers are responsible to a certain degree to keep HVAC workers safe from the extreme heat, 1 there are also things that HVAC technicians can do on their own to work safely outside without putting their health at risk.

Know Your Limits and the Risks

How much heat you can handle depends on your weight, how much physical activity is required to complete a job, and humidity levels. Generally speaking, a person can work comfortably in 73o F heat with 45% humidity; however, labor-intensive work can cause the safe temperature limit to drop down to 550F. 2 If you’ve just graduated from an HVAC program, you should be familiar with HVAC safety practices, but it’s always good to receive some reminders.

Health problems that can occur when working in overly hot temperatures for an extended period of time include:

  • Dehydration
  • Heat rash
  • Heat cramps
  • Exhaustion
  • Fainting
  • Heat stroke
