What is the first thing you should do before using an electrical drill?

The appropriate first step before using an electrical drill is to inspect the electrical cord for damage. This is crucial for ensuring safety while operating the tool. A damaged electrical cord can pose a serious risk of electric shock, fires, or tool malfunction, so it must be in good working condition before any other preparations are made.

Additionally, while selecting the correct drill bit, checking the hole diameter, and ensuring appropriate lighting are important considerations for effective and safe drilling, they should come after confirming the drill and its components are safe to operate. Safety checks like inspecting cords are foundational to preventing accidents and injuries in the work environment.
