If an electric motor to a pump is not working, what is the first step to take before repairing it?

The appropriate first step when addressing an electric motor that is not functioning is to lock it out and tag the switch. This action is crucial for safety reasons. Locking out the equipment ensures that no one can inadvertently turn the power back on while repairs are being made, protecting personnel from potential electrical hazards. Tagging the switch serves as a warning to others that the equipment is out of service and being worked on, further enhancing safety.

While checking the power supply, inspecting the wires, or cleaning the motor may also be necessary steps to troubleshoot the issue, they should follow the lockout/tagout procedure. Prioritizing safety through proper lockout and tagging procedures is essential in any maintenance or repair situation, particularly in environments dealing with electrical equipment.
