Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

Clothing worn to protect against electrical shock must be what?

1. Non-conductive

2. Conductive

3. Flame resistant

4. Designed for the voltage to which they will be exposed

The correct answer is: Non-conductive

Clothing worn to protect against electrical shock must be non-conductive because this type of clothing prevents electricity from flowing through the body and causing serious injuries or fatalities. Non-conductive materials do not allow electrical current to pass through, thereby reducing the risk of shock when a person is working near live electrical sources. This is crucial in environments where workers are exposed to electrical hazards, as it helps create a barrier between the person and any potential electrical currents. The protective nature of non-conductive clothing is vital for ensuring safety while performing tasks that involve electrical work, maintenance, or operations where there is a risk of electrical exposure. In addition to being non-conductive, it is also important that such clothing does not provide pathways for electrical current to reach the skin. The design and materials used are specifically chosen to minimize any risk of electrical conduction. While flame resistance, as mentioned in one of the options, is important for certain safety applications, it does not directly address the electrical shock hazard. Instead, the focus here is on the non-conductive nature of the fabric, which is essential for worker safety in electrical environments.
