Once you finish your HVAC classes and enter the field, it is likely that you’ll work with electrical equipment and circuits. The installation of an HVAC system and troubleshooting of problems often requires HVAC techs to handle electrical wiring. Understanding electrical safety practices can help protect you on the job. 1 Following is an overview.

What Are Electrical Safety Rules?

The Occupational Safety and Health Administration (OSHA) has electrical safety standards for several industries. Its “Design and Safety Standards for Electrical Systems” are published in Title 29 Code of Federal Regulations (1910.302-1910.308). You can also find OSHA’s “Electrical Safety-Related Work Practices Standards” in Title 29 (1910.331-1910.335). These electrical standards derive from the National Fire Protection Association’s National Electric Code and Electrical Safety Requirements for Employee Workplaces. 2

OSHA Safety Precautions

Here are a few OSHA electrical safety precautions whenever working with electrical wiring and components.

1. De-energize (Turn Off) Electrical Equipment

2. Use Lockout and Tag Procedures

Before inspecting or repairing HVAC equipment, make sure electricity is not flowing through it by turning off the power to the circuit at the service entrance panel. Padlock the switch in the OFF position. Attach a tag to the lock and write your company’s name, your name, the date, and the reason the breaker is locked out. In case where work is being done on a commercial property, this will let maintenances supervisors know not to turn the power back on. 3 4

3. Multimeters

A volt-ohm-meter, or multimeter, can be used to test if the circuit is energized. Make sure to use a meter that is rated for the type of circuit you’re testing or you may not be adequately protected.

4. Wear Personal Protective Equipment

Personal protective equipment (PPE) can help reduce the risk of electrical accidents. Examples of PPE for working with electricity include insulated blankets, hoods, gloves, and helmets. 5 Never wear jewelry or other conductive materials when working with electricity, including clothing made of synthetic fiber. Always wear a face shield or safety glasses when working with electrical circuits. 6

Safety First

When working with electricity, there is no room for mistakes. Following electrical safety practices can help prevent accidents and injuries.
