Final answer:
The claim that safety guards on power tools can be removed when necessary is false since they are critical for user protection. Working one-handed with electrical circuits minimizes the risk of severe electric shock. Familiarity with the location of safety equipment in a lab setting is vital for rapid response to emergencies.
Step-by-step explanation:
The statement that standard safety guards on power tools can be removed only when necessary to get the job done is False.
Safety guards are an essential part of power tools that protect the user from potential hazards like flying debris, accidental contact with moving parts, and other risks associated with using power tools. These guards should remain in place as much as possible to ensure user safety.
When working with high-power electric circuits, it is a sensible suggestion to work "one-handed" or "keep one hand in your pocket" to minimize the risk of electrical current passing through the heart if contact is accidentally made with a live circuit. This safety technique helps to prevent the completion of an electrical path through the body, which can be life-threatening.
Knowing where specific safety equipment, such as the fire extinguisher and the eyewash station, is located in the laboratory is crucial. In the event of an emergency, such as a fire or chemical splash in the eyes, quick and efficient access to this equipment can prevent serious injuries or mitigate damage.
