Final answer:
Electricians require specialized fall protection gear such as full body harnesses, lanyards, retractable lifelines, and anchorage points, in addition to standard safety helmets. Plastic insulation on wires helps prevent both shock and thermal hazards.
Step-by-step explanation:
Electricians and Fall Protection Gear
The question is about what additional gear electricians require for fall protection. Fall protection is critical for electricians working at heights to ensure safety from falls that could result in serious injury or death. In addition to basic safety equipment such as safety helmets, electricians need specialized fall protection gear which includes full body harnesses, lanyards, retractable lifelines, and anchorage points. These are designed to arrest a fall and minimize the impact on the body. Harnesses are fitted to the body, and lanyards or lifelines are connected to secure anchor points, ensuring that if an electrician slips or falls, the fall is stopped safely.
In the context of electrical safety systems and devices, plastic insulation on live/hot wires is specifically designed to prevent both shock and thermal hazards. This is because the insulation serves as a barrier that obstructs the flow of electrical current, thus preventing accidental shocks, and also functions to contain the heat produced by electrical resistance within the wires.
