How should you handle electrical equipment in the lab?

Handling electrical equipment in the lab requires a high level of care and attention to safety. Ensuring that cords are inspected for damage before use is crucial because damaged cords can lead to electrical shocks or fires, posing serious safety risks. Additionally, having dry hands prevents the risk of conducting electricity through your body, which significantly reduces the chances of electrical accidents.

The importance of this practice lies in the prevention of incidents that can arise from faulty equipment or improper handling. By examining cords for signs of wear and ensuring your hands are dry, you mitigate risks associated with using electrical devices, which can be particularly hazardous in a laboratory environment where spills and other hazards may be present.

While the other options address safety concerns in different ways—such as avoiding tripping hazards, ensuring proper labeling, and confirming that equipment is not in use—they do not directly focus on the immediate risks associated with electrical faults and personal safety during the operation of electrical devices.
