What Do You Know About Lockout-tagout (Loto)? - Quiz

Lockout-Tagout (LOTO) is a safety procedure used in the industry to ensure that dangerous machines are properly shut off and not able to be started up again before the completion of maintenance or repair work. This is a procedure that has led to the prevention of a lot of accidents at a workshop. Test out what you know about this procedure by taking this quiz.


Questions and Answers
  • 1. 

    In a lockout, an energy isolating device is locked in a safe or off position.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    In a lockout, an energy isolating device is locked in a safe or off position. This means that when a lockout is implemented, the energy isolating device is physically locked in a position that prevents the release or transmission of energy. This ensures the safety of workers who are performing maintenance or repairs on machinery or equipment, as it prevents unexpected startup or release of energy that could cause harm or accidents.

    The process of locking out and tagging can also be referred to as Control of Hazardous Energy Sources.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The process of locking out and tagging is indeed referred to as Control of Hazardous Energy Sources. This process involves isolating energy sources and placing locks and tags on them to prevent accidental energization or startup of machinery or equipment during maintenance or repair. By doing so, it helps ensure the safety of workers by preventing the release of hazardous energy that could cause injury or harm. Therefore, the statement is true.

    Before you turn off equipment for lockout/tagout, you must know all the different types of energy it uses.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Before turning off equipment for lockout/tagout, it is essential to be aware of all the various types of energy that the equipment uses. This knowledge is crucial for ensuring the safety of individuals performing lockout/tagout procedures. By understanding the different energy sources, such as electrical, mechanical, thermal, or hydraulic, workers can effectively isolate and control the energy to prevent accidental startup or release. Therefore, it is true that knowing all the different types of energy used by the equipment is necessary before initiating lockout/tagout.
