Question

and that a conductor on the green grounding wire was making intermittent contact with the energizing black wire thereby energizing the entire length of the grounding wire and the drill’s frame. the drill was not double insulated. what could have been done to prevent this accident? select all that apply.

checkbox options:

• use approved ground fault circuit interrupters or an assured equipment grounding conductor program to protect employees on construction sites
• inspect electrical tools and equipment daily and remove damaged or defective equipment from use until it is repaired
• there is no way to prevent an accident such as this from occurring
• use equipment that provides a permanent and continuous path from circuits, equipment, structures, conduits or enclosures to ground

Explanation:

1. "Use approved ground fault circuit interrupters or an assured equipment grounding conductor program to protect employees on construction sites" - Ground fault circuit interrupters (GFCIs) and proper grounding conductor programs are standard safety measures to prevent electrical shocks by interrupting faulty circuits or ensuring proper grounding.
2. "Inspect electrical tools and equipment daily and remove damaged or defective equipment from use until it is repaired" - Regular inspections can identify faulty equipment (like the drill with wiring issues here) and removing them from use prevents accidents.
3. "There is no way to prevent an accident such as this from occurring" - This is incorrect as there are established safety protocols (like the other options) to prevent electrical accidents.
4. "Use equipment that provides a permanent and continuous path from circuits, equipment, structures, conduits or enclosures to ground" - Proper grounding equipment ensures that any energized parts are safely grounded, preventing shocks.

Answer:

• Use approved ground fault circuit interrupters or an assured equipment grounding conductor program to protect employees on construction sites
• Inspect electrical tools and equipment daily and remove damaged or defective equipment from use until it is repaired
• Use equipment that provides a permanent and continuous path from circuits, equipment, structures, conduits or enclosures to ground
