Aworker was attempting to correct an electrical problem involving two non-operational lamps. he proceeded to the area
where he thought the problem was. he had not shut off the power at the circuit breaker panel nor had he tested the wires to
see if they were live. he was electrocuted when he grabbed the two live wires and then fell from the ladder. what could have
been done to prevent this accident from occurring

The thing that could have been done to prevent this accident from occurring is that he could have shut off the power first.

It's important for individuals to always switch off electrical appliances when they're not in use. Electrical Safety is important in hazardous situations.

Based on the scenario given, he did not shut off the power at the circuit breaker panel. Therefore, in order to prevent the accident from not occurring, he could have shut off the power first.

He could have shut off  the power first and de-energize the circuits in order to prevent being electrocuted.

Explanation:

Electrical Safety is very important, especially for those working in such hazardous situations. Almost all our things in the society are electrically-operated, thus it even becomes relevant to have an idea on how we can prevent from obtaining an electrical shock or burns due to faulty electrical tools.

In the worker's scenario above, it is clear that he did not shut off the power at the circuit breaker panel. This is the most important thing that one must include in his plan when attempting to correct an electrical problem. You must find where the electrical switch, fuses and circuit breakers are at first. Once you find their location, you have to turn them off (even if the circuits are of low-voltage). In order to make sure that they are really turned off, test the circuits first. This will help you ensure that they are, indeed, de-energized.
