Final answer:
When working with electrical or electronic equipment, stools made from fiberglass or non-conductive materials are recommended for safety, along with wearing insulated shoes and using plastic insulation on live wires.
Step-by-step explanation:
When working on electrical or electronic equipment, it is essential to use stools made from fiberglass or other non-conductive materials for safety reasons. Our bodies conduct electricity well, primarily due to their water content, creating a risk when working with voltage sources. To mitigate this hazard and ensure safety, one should not only use non-conductive stools but also avoid being a pathway for electricity. For instance, wearing insulated shoes can prevent a pathway to the ground, inhibiting electrical current flow through the body, which could lead to serious injuries or even death.
Additional safety measures include using plastic insulation on live or hot wires. This insulation serves to protect against both shock and thermal hazards. It is also advisable to work with one hand while dealing with electrical systems to reduce the risk of current flowing through the heart, another critical safety precaution.
