What is a fundamental safety step before starting any HVACR service?

De-energizing and isolating the HVACR system before you work is essential to stay safe. By disconnecting power and ensuring the equipment can’t be re-energized, you prevent shocks, burns, and arc flash while you perform maintenance or repairs. Applying lockout/tagout devices and following the procedure stops any accidental startup, which is the cornerstone of safe servicing. Wearing the proper PPE and using insulated tools further protects you from residual energy and other hazards you might encounter during the work. In contrast, turning the power back on while you’re working, ignoring PPE, or working with the system energized creates immediate and serious safety risks and is not acceptable.
