If, while using the brush machine, you accidentally drop the equipment into a sink full of water, which of the following should you do?

• A. You should unplug the faucet.
• B. You should quickly unplug the brush machine from the outlet
• C. You should push it away
• D. You should continue using it

Answer: (B)

When a powered device falls into water, the risk is electric shock and a possible short circuit. The quickest and safest response is to disconnect the power at its source. Unplugging the brush machine from the outlet removes the electrical supply and greatly reduces the danger, as long as you can reach the plug safely. Do not try to grab the device while it’s in water, and if the plug isn’t reachable, switch off the circuit breaker or call for assistance.

Unplugging the faucet is irrelevant to stopping the electrical current. Pushing the device away while it’s in water still leaves it energized and dangerous. Continuing to use it is not an option—you’d be exposing yourself to severe risk.
