Which of the following applies in a lockout/ tagout procedure?
Select one:
a. Only the supervisor can install lockout/tagout devices.
b. If several employees are involved, the lockout/tagout equipment is applied only by the first employee to arrive at the disconnect.
c. Lockout/tagout devices applied by one employee can be removed by another employee as long as it can be verified that the first employee has left for the day.
d. Lockout/tagout devices are installed by every authorized employee involved in the work.
The Correct Answer and Explanation is:
The correct answer is:
d. Lockout/tagout devices are installed by every authorized employee involved in the work.
Explanation:
Lockout/tagout (LOTO) procedures are critical safety protocols in industrial settings to prevent accidental equipment start-up or the release of hazardous energy during maintenance or repair work. These procedures are designed to protect workers from serious injuries that could occur if machinery were inadvertently energized.
In a typical lockout/tagout procedure, the following steps are followed:
- Authorized Employees: Only trained and authorized personnel are allowed to install, maintain, and remove lockout/tagout devices. These devices ensure that energy sources (such as electrical, mechanical, hydraulic, or thermal) are properly isolated before any maintenance begins.
- Multiple Employees Involved: When multiple workers are involved in a lockout/tagout process, each authorized employee working on the equipment is responsible for installing their own lock or tag to ensure their safety. This is because each employee needs to have control over their own personal energy isolation, which prevents any risk of equipment re-energizing while they are working on it.
- Ownership and Responsibility: While the lockout/tagout devices are applied by every authorized employee involved in the work, each lock or tag serves as a visual and physical indication that an employee is working on the equipment. The locks remain in place until the work is completed, and all employees are clear of the equipment.
Why the Other Options Are Incorrect:
- a. Only the supervisor can install lockout/tagout devices.
This is incorrect because lockout/tagout devices can only be installed by authorized employees, not just a supervisor. Supervisors typically ensure that procedures are followed, but installation is the responsibility of the workers involved. - b. If several employees are involved, the lockout/tagout equipment is applied only by the first employee to arrive at the disconnect.
This is incorrect because every employee involved in the work needs to apply their own lockout/tagout devices, not just the first employee. This ensures individual safety and accountability. - c. Lockout/tagout devices applied by one employee can be removed by another employee as long as it can be verified that the first employee has left for the day.
This is incorrect. Lockout/tagout devices should only be removed by the person who applied them, or in rare circumstances, another employee may remove the device if they have clear authorization and verification of the original employee’s absence or completion of their work.
Therefore, d is the correct choice, as it adheres to the principle that each authorized employee must ensure their own safety by installing and maintaining their lockout/tagout devices while working on equipment.
