Final answer:
Electrical PPE with any defects, including insulated gloves, safety glasses, flame-resistant clothing, and insulated tools, must not be used as they protect against electrical hazards such as shock and thermal injuries. Intact and properly maintained PPE is crucial for safety in environments with electrical risks.
Step-by-step explanation:
The correct option is E:
Electrical personal protective equipment (PPE) with any defects must not be used, so the direct answer is e. all of the above. This includes insulated gloves, safety glasses, flame-resistant clothing, and insulated tools. These components are critical for protecting against electrical hazards, both thermal and shock. For instance, insulated gloves prevent electric shocks when handling live equipment by providing an insulating barrier between the electrical source and the person. Safety glasses are essential to protect against arc flash and flying debris that might result from electrical work. Flame-resistant clothing protects against potential fires that can occur from electrical sparks and arc flashes. Insulated tools prevent electrical current from passing through to the user, offering protection during the manipulation of electrical components.
The need for undamaged PPE is highlighted by the fact that plastic insulation on live/hot wires serves to prevent both shock and thermal hazards, by acting as a barrier against electrical current and reducing the chance of wires becoming hot enough to ignite surrounding materials. The significance of correctly functioning and intact PPE cannot be overstated as it is the first line of defense against serious injuries in an electrical work environment.
