Working as an HVAC technician can be a physically demanding job that includes repairing dangerous machinery, installing heavy systems and working in close quarters, all of which can result in HVAC workplace accidents and HVAC workplace injuries.
Since there is potential for HVAC accidents every day, it’s important to take note of how to identify and prevent some of the most common HVAC mistakes and hazards we see across the industry. Let’s take a look at the most common HVAC accidents and HVAC contractor injuries.
1. Musculoskeletal Disorders
Slips, trips, and falls cause approximately 25% of all injuries sustained across all industries. For our contractors, the most common HVAC worker injuries resulting from these accidents tend to be musculoskeletal disorders (MSDs), including:
- Muscle strains
- Low back injuries
- Rotator cuff injuries
- Carpal tunnel syndrome
- Tendinitis
The best way to prevent these HVAC contractor injuries is to take your time and utilize proper precautions when using or transporting heavy equipment. Try to avoid actions that put your body posture in awkward positions for extended periods with repetitive motions. If you’re working alone, try to make sure that you’re not overly straining your body by lifting or moving machinery that requires additional support.
2. Electrical Hazards
HVAC work requires handling electrical wiring, so before you begin to work, it’s crucial that you de-energize any equipment requiring tests, repairs, inspections or other services. Additionally, be sure to follow these tips to avoid electrical HVAC accidents:
- Turn off power to the corresponding circuit in the breaker panel.
- Use proper lockout and tag procedures to keep others from turning the power back on until the work on the unit is complete.
- Test the circuit with a meter that is appropriately rated for the type of circuit you’re testing before beginning the job.
3. Chemical Exposure
One of the leading HVAC accidents we see across the industry is exposure to dangerous chemicals. Technicians often work with a variety of chemicals that can cause severe burns, such as refrigerants, cleaning liquids, solvents, and gases.
Proper HVAC safety training is crucial before working with these chemicals, and once you’re on the job, always be sure to wear reliable protective personal equipment (PPE), including safety glasses, protective footwear and HVAC work gloves.
HVAC contractors also commonly handle pressurized gas cylinders used to store R-410A refrigerant. Extreme heat or on-site conditions can make these cylinders potentially volatile if bumped or tipped over, so be sure to follow these storage and handling steps to avoid HVAC worker injuries:
- Secure cylinders in an upright position with a chain or strap in a proper cylinder cart
- Make sure valves are entirely closed and any protection devices are secured.
- Keep cylinders in a ventilated location that is closed off from excessive heat and electrical circuits.
- Ensure safety measures, such as caps or guards, are securely installed.
- Always use a cart or hand truck – do not drag or roll cylinders.
4. Respiratory HVAC Contractor Injuries
One of the most common HVAC hazards technicians are exposed to are respiratory-related. Dirty HVAC and air conditioner filters are a safety hazard that can catch bacteria, mold, and fungus. Carbon monoxide poisoning can result from both faulty pilot lights and furnace heat exchangers.
Always wear industrial-grade face masks to prevent inhaling airborne poisons, especially when working near them for extended periods. Some jobs may also require a higher-grade mask, such as a cartridge-style mask or even a self-contained breathing mask, especially if the job is in a contaminated and confined space. For more information, refer to the Occupational Safety and Health Administration (OSHA) respiratory safety standards.
5. Ladder Liability
Ladders are inherently dangerous, so taking proper precautions while using this equipment on the job is critical to avoid HVAC accidents. Follow these tips to prevent common HVAC worker injuries:
- Always maintain three-point contact, meaning either both feet with at least one hand or both hands with at least one foot on the ladder at all times.
- Make sure the ladder’s base is at a safe angle, placing it one-fourth of its working height (length) from the wall supporting it.
- Make sure extension or straight ladders extend at least 3 feet above the point of support.
- Engage and set all locks when using a folding or extension ladder.
6. Extreme Weather Conditions
HVAC technicians frequently work outside in extreme heat or cold, putting them at risk for fatigue, dehydration, heat stroke, hypothermia and frostbite. For these common HVAC hazards, it’s critical that you know your limits, wear the proper clothing, hydrate, and take breaks to avoid these HVAC contractor injuries.
