What should be ensured before working with light fixtures?

Before working with light fixtures, it is crucial to ensure that the power is off. This is essential for safety reasons; when the power supply to the fixture is turned off, it helps prevent electric shock or injury while performing any tasks related to the light fixtures. Working with live electrical components is highly dangerous, and many accidents can occur if precautions aren't taken to ensure that power has been disconnected.

While having clean fixtures, replaced light bulbs, and the proper tools can be important in maintaining and repairing light fixtures, these aspects do not address the immediate safety concerns associated with electricity. Ensuring that the power is off directly impacts the safety of the technician and anyone else nearby, making it the most critical step before any work begins on light fixtures.
