Lock Out Tag Out Quiz - Quiz

Questions and Answers
  • 1. 

    The unexpected release of energy is a major hazard during servicing or maintenance.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    During servicing or maintenance, there is a potential for stored energy to be released unexpectedly. This can occur in various forms such as electrical energy, mechanical energy, or chemical energy. If proper precautions are not taken, this release of energy can lead to accidents, injuries, or even fatalities. Therefore, it is important to be aware of this hazard and take necessary safety measures while performing servicing or maintenance tasks.

    Rate this question:

  • 2. 

    OSHA estimates that lockout/tagout protects approximately 3.3 million employees each year.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Lockout/tagout is a safety procedure used in the workplace to ensure that hazardous energy sources are properly isolated and prevented from being accidentally activated during maintenance or repair work. OSHA (Occupational Safety and Health Administration) estimates that this procedure protects approximately 3.3 million employees each year. This means that by implementing lockout/tagout measures, a significant number of workers are safeguarded from potential accidents and injuries caused by the unexpected release of hazardous energy. Therefore, the statement that the answer is true is supported by OSHA's estimation of the number of employees protected by lockout/tagout.

    Rate this question:

  • 3. 

    A person who locks out machines or equipment is an Authorized Employee.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    An Authorized Employee is someone who has been given the authority and responsibility to lock out machines or equipment. This means they have the necessary training and knowledge to safely secure and disable the machinery or equipment to prevent accidental startup or release of stored energy. Therefore, the statement that a person who locks out machines or equipment is an Authorized Employee is true.

    Rate this question:

  • 4. 

    The four main types of energy discussed were electrical, mechanical, hydraulic, and turbine.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    electrical, mechanical, hydraulic, pneumatic

    Rate this question:

  • 5. 

    Turning off a machine does not necessarily stop all energy to the machine

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Turning off a machine may not completely stop all energy flow to the machine because some appliances or devices have standby modes or continue to consume a small amount of energy even when they are turned off. This is commonly known as standby power or vampire power. Additionally, some machines may have residual energy stored in capacitors or batteries that can still be discharged even when the machine is turned off. Therefore, it is true that turning off a machine does not necessarily stop all energy to the machine.

    Rate this question:

  • 6. 

    Lookout is just tuning a machine off and unplugging it before performing maintenance.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement implies that Lookout is only turning off and unplugging the machine before performing maintenance. However, proper maintenance procedures typically involve additional steps such as ensuring the machine is properly locked out, tagged out, and isolated from any energy sources to prevent accidental startup. Therefore, the given statement is false.

    Rate this question:

  • 7. 

    Tagout can be used instead of lockout whenever an employer wants.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is incorrect. Tagout cannot be used instead of lockout whenever an employer wants. Lockout and tagout are two separate procedures used to ensure the safety of workers during maintenance or repair of equipment. Lockout involves physically isolating the equipment from its energy source using a lock, whereas tagout involves using a tag to indicate that the equipment should not be operated. Both procedures have specific requirements and are used in different situations to prevent accidents and injuries. Therefore, tagout cannot be used as a substitute for lockout whenever an employer wants.

    Rate this question:

  • 8. 

    Tags don't lock out energy but only warn of the dangers.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Tags do not physically prevent or lock out energy, but they serve as a warning or indication of potential dangers. They are typically used to communicate hazards or risks associated with certain objects, areas, or activities. Therefore, it is true that tags do not lock out energy but only provide a cautionary message.

    Rate this question:

  • 9. 

    The lockout process is a six-step procedure.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that the lockout process indeed consists of six steps. These steps are followed to ensure the safety of workers when working with potentially hazardous machinery or equipment. By following this procedure, the equipment is properly shut down, isolated from its energy source, and locked out to prevent any accidental startup or release of stored energy. This helps to protect workers from potential injuries or accidents while performing maintenance or repairs on the equipment.

    Rate this question:

  • 10. 

    Before starting work on a machine that has been locked out, the Authorized Employee must confirm the isolation of energy to the machine.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Before starting work on a locked-out machine, the Authorized Employee must confirm the isolation of energy to the machine. This means that the employee must ensure that all energy sources to the machine, such as electricity or hydraulic power, have been effectively disconnected or isolated. This is a crucial safety measure to prevent any unexpected energy release or activation of the machine, which could lead to accidents or injuries. Therefore, it is important for the Authorized Employee to confirm the isolation of energy before commencing work on a locked-out machine.

    Rate this question:

  • 11. 

    A lock out device can be removed by an employer when the employee that placed the device is not present.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Lock out devices are used to ensure the safety of employees working with hazardous machinery or equipment. These devices are typically placed by the employees themselves to prevent accidental startup or release of stored energy. However, there may be situations where the employee who placed the device is not present, such as during shift changes or breaks. In such cases, it may be necessary for the employer to remove the lock out device in order to resume operations. Therefore, the statement that a lock out device can be removed by an employer when the employee is not present is true.

    Rate this question:

  • 12. 

    When a group lockout is necessary, one crew member is given primary responsibiity of the crew.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    In a group lockout, it is necessary to assign one crew member with the primary responsibility of overseeing the lockout process. This individual will ensure that all necessary steps are followed, all equipment is properly locked out, and that the crew members are safe. This helps to streamline the process and maintain accountability within the group. Therefore, the statement "When a group lockout is necessary, one crew member is given primary responsibility of the crew" is true.
