OSHA 10 Hour Construction Program Practice Test

What are the two best means of avoiding injury from electrical devices?

1. Insulation and grounding

2. Proper wearing of safety gear

3. Maintaining a safe distance

4. Regular tool inspections

The correct answer is: Insulation and grounding

Insulation and grounding are fundamental safety measures when working with electrical devices. Insulation serves as a barrier that prevents accidental electrical contact with conductive materials, thereby reducing the risk of shock or electrocution. It is crucial in ensuring that wires and components do not unintentionally conduct electricity to areas where it could pose a danger to workers. Grounding, on the other hand, provides a safe pathway for electricity to flow back to the ground in the event of a fault, such as a short circuit. This reduces the likelihood of electrical shock by ensuring that excess electrical energy is safely redirected, minimizing the risk of injury. While proper wearing of safety gear, maintaining a safe distance, and conducting regular tool inspections are important practices for overall safety, they do not address the specific risks associated with electrical devices as effectively as insulation and grounding do. Insulation and grounding tackle the root causes of electrical hazards, making them the best means to avoid injury in this context.
