Final answer:
In isolating a piece of equipment as a separate unit, safety measures like isolation transformers, pressure gauges, and proper electrical safety devices must be present to ensure safe operation and maintenance, especially in high-risk environments like laboratories and nuclear facilities.
Step-by-step explanation:
If any piece of equipment can be isolated as a separate unit, there must be mechanisms in place to ensure safety and proper isolation during its operation or maintenance. Typically, an isolation transformer or similar device is used to electrically isolate the equipment from the power source to prevent electric shock. Additionally, depending on the equipment being used, various forms of pressure gauges, such as ionization gauges or standard mechanical gauges, and safety devices like circuit breakers, fuses, or ground fault interrupters (GFI) might be necessary for monitoring and ensuring safe operation. In a laboratory setting, knowing the location of safety equipment such as fire extinguishers and eyewash stations is crucial. Moreover, in systems involving potentially hazardous materials, such as separate water systems in nuclear reactors, it is vital that these systems do not mix and that there are auxiliary safety systems in place in case of accidents, such as a loss of coolant.
