Which of the following is a safe practice when handling electrical equipment?

Ensuring safety when handling electrical equipment is paramount, and checking equipment before use plays a crucial role in maintaining that safety. This practice involves inspecting all tools and devices for any visible damage, such as frayed wires or worn-out insulation, that could lead to accidents or equipment failure. Additionally, verifying that the equipment is rated for the intended voltage and current levels helps prevent overload situations, which could result in hazards such as electric shock, fire, or equipment damage.

In contrast, the other choices don't promote safe handling practices. Simply using gloves is insufficient if the equipment itself is defective or unsafe to operate. Ignoring voltage ratings can lead to serious electrical incidents, and operating under any condition compromises safety since conditions could include factors such as wet environments or the presence of flammable materials, which significantly increase risk. Therefore, thorough checks before using electrical equipment are a fundamental aspect of safe practice.
