Lockout/Tag out is a system used to ensure that equipment you’ve isolated and de-energized to work on remains shut down
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Lockout/Tag out is a safety procedure used to ensure that equipment or machinery that has been isolated and de-energized for maintenance or repair work remains shut down and cannot be accidentally or unintentionally started up. This system involves the use of locks and tags to physically lock the equipment and clearly indicate that it should not be operated. By implementing lockout/tag out procedures, workers are protected from potential hazards and accidents that could occur if the equipment were to be energized while being worked on. Therefore, the statement "Lockout/Tag out is a system used to ensure that equipment you’ve isolated and de-energized to work on remains shut down" is true.Rate this question:

Lockout /Tag out procedure can be applied to ...
- A.
Circuits that receive energy from electrical power
- B.
Energy stored in springs
- C.
Potential energy from suspended parts
- D.
Hydraulic fluid under pressure
- E.
All Above
Correct Answer
E. All AboveExplanation
The lockout/tag out procedure can be applied to all the options mentioned above. It is a safety procedure used to ensure that hazardous energy sources are isolated and rendered inoperative before maintenance or servicing work is performed. This includes circuits that receive energy from electrical power, energy stored in springs, potential energy from suspended parts, and hydraulic fluid under pressure. By implementing lockout/tag out, workers are protected from unexpected release of energy and potential accidents.Rate this question:

Work permit is NOT essential to perform any isolation for lockout/tag out.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A work permit is essential to perform any isolation for lockout/tag out. Lockout/tag out procedures are used to ensure that equipment is properly isolated and de-energized before any maintenance or repair work is performed. A work permit is a document that authorizes and controls the work being done, and it includes information about the specific isolation procedures that need to be followed. Without a work permit, it would be unsafe to perform any isolation for lockout/tag out as there would be no formal authorization or control over the work being done. Therefore, the statement that a work permit is not essential for lockout/tag out is false.Rate this question:

You know the equipment is safe when the power has been shut down
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement suggests that the equipment is safe only when the power has been shut down. However, this is not entirely true as there are other factors that determine the safety of the equipment. While shutting down the power is an important step in ensuring safety, there may be other hazards or risks associated with the equipment that need to be addressed. Therefore, the statement is false.Rate this question:

Locks should be removed only by the person who installed them
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Locks should be removed only by the person who installed them to ensure security and prevent unauthorized access. By allowing only the installer to remove the locks, it ensures that only trusted individuals have control over access to the locked area or object. This helps maintain accountability and reduces the risk of tampering or unauthorized entry.Rate this question:

Verifying isolation involves
- A.
Putting locks on the equipment
- B.
Putting a tag on the equipment
- C.
Attempting to turn the machine on
Correct Answer
C. Attempting to turn the machine onExplanation
The correct answer is "Attempting to turn the machine on" because verifying isolation requires checking if the equipment is truly isolated from its power source. This can be done by attempting to turn the machine on, as a successful start-up would indicate that the isolation has not been properly implemented. If the machine does not start, it confirms that the isolation measures are in place and effective. Putting locks and tags on the equipment are common isolation procedures, but they do not directly verify if the isolation has been achieved.Rate this question:

When electrical isolation or disconnect needs to be carried out, a certificate of electrical isolation should be initiated in addition to the master card. The master card is likely a key or access card that grants permission to perform electrical isolation or disconnect. This card is necessary to ensure that only authorized personnel are able to carry out these procedures, maintaining safety and preventing any unauthorized access or accidents.Rate this question:

- A.
A gang-lock device
- B.
Multiple isolation form
- C.
Tag out
Correct Answer
A. A gang-lock deviceExplanation
A gang-lock device is the correct answer because it allows multiple employees to lock and tag out a piece of equipment or machinery together. This ensures that all employees involved in the job are aware of the lockout/tagout procedure and have control over the energy sources. By using a gang-lock device, each employee can hang their own lock and tag, indicating that they are actively working on the equipment and that it is not safe to operate. This helps prevent accidental startup or release of stored energy, ensuring the safety of all employees involved.Rate this question:

According to GAS Lockout /Tag out procedure , the first lock should be installed by
- A.
Maintenance
- B.
Reliability
- C.
Operation
Correct Answer
C. OperationExplanation

This is because the Operation department is responsible for the day-to-day operation and maintenance of the equipment. They have the necessary knowledge and expertise to ensure that the equipment is properly locked out or tagged out to prevent any unexpected startup or release of energy. The Operation department is also typically the first point of contact when it comes to initiating maintenance or repair work, making it logical for them to be the ones to install the first lock.Rate this question:
