Lock Out Tag Out

Explanation
In a lockout, an energy-isolating device is indeed locked in the safe or off position. This ensures that the equipment or machinery is completely shut down and cannot be accidentally or unintentionally operated, preventing any potential hazards or accidents. By locking the energy-isolating device, it ensures that no energy source is available to power the equipment, making it safe for maintenance or repairs to be carried out.

Explanation
In a tagout, the energy-isolating device is placed in the safe position and a written warning is attached to it. This is done to effectively communicate to workers that the equipment is being serviced or repaired and should not be operated. By placing the device in the safe position and attaching a written warning, it ensures that anyone who comes across the equipment understands the potential dangers and takes necessary precautions. This is an important safety measure to prevent accidents and injuries.

Explanation
A worker cannot use any sturdy lock to apply a lockout. Instead, they must use a specific type of lock called a lockout/tagout device. These devices are designed to securely lock machinery or equipment in a deactivated state, preventing accidental or unauthorized use. Using any other type of lock may not provide the necessary level of safety and security required for a proper lockout procedure.

Explanation
Lockout/tagout is a safety procedure used to prevent accidents caused by the unexpected start-up or release of stored energy in machines during service or maintenance. By using lockout/tagout, the machine is effectively shut down and rendered inoperable, ensuring that no one can accidentally start it while work is being done. This prevents potential injuries and ensures the safety of workers. Therefore, the statement "Lockout/tagout should be used whenever you are performing service or maintenance around any machine where you could be injured by unexpected start-up or release of stored energy" is true.

Explanation
This statement is false because the decision to use lockout, tagout, or both is not up to individual employees. The use of lockout, tagout procedures is mandated by safety regulations and is typically determined by the employer or the organization's safety policy. These procedures are put in place to ensure the safety of employees when working with or around hazardous energy sources.

Explanation
Applying locks or tags in the right places does not de-energize the equipment. Locks and tags are used as part of a lockout/tagout procedure to isolate and control energy sources, ensuring that equipment cannot be accidentally or unintentionally energized. Locks and tags are used to indicate that maintenance or servicing is being performed on the equipment, and they serve as a visual reminder to others that the equipment should not be operated. However, locks and tags themselves do not physically de-energize the equipment.

Explanation
Turning off the power switch does not necessarily remove all energy from powered equipment. While it may disconnect the equipment from its power source, there could still be stored energy in capacitors or batteries within the equipment. Therefore, the statement is false.

Explanation
Engineering safety features are not foolproof ways of protecting workers from hazardous energy. While these features are designed to minimize risks and enhance safety, they are not guaranteed to be completely foolproof. There is always a possibility of human error, mechanical failure, or unforeseen circumstances that can compromise the effectiveness of these safety features. Therefore, it is important for workers to remain vigilant and follow proper safety protocols to ensure their own protection.

Explanation
The given statement states that an inspection will be conducted by the shop supervisor and ground safety at least once a year to ensure that current LOTO (Lockout/Tagout) procedures are in place. This implies that the organization takes safety measures seriously and regularly checks if the necessary procedures are being followed. Therefore, the statement is true.

Explanation
Before lockout/tagout is applied, it is important to notify all workers in the affected area. This is necessary to ensure the safety of all employees and to prevent any accidents or injuries. By notifying all workers, they can be aware of the lockout/tagout procedure and understand the potential hazards associated with the equipment or machinery being locked out or tagged out. This ensures that everyone is on the same page and can take the necessary precautions to avoid any accidents or injuries.

Explanation
Before turning off equipment in order to lock or tag it out, it is crucial to know the type of energy it uses, the hazards associated with that energy, and how to control it. This is essential for ensuring the safety of individuals working on or around the equipment. By having a thorough understanding of the energy source and its potential risks, proper precautions can be taken to prevent accidents and injuries. Therefore, the statement "True" is correct.

Explanation
The statement suggests that once the system is isolated from its main power source, no energy will reach the equipment. However, this is false. Even when the system is isolated from the main power source, there can still be stored energy in the equipment, such as in capacitors or batteries, which can continue to power the equipment. Therefore, it cannot be guaranteed that no energy will reach the equipment.

Explanation
In a lockout, multiple people are allowed to attach their own individual locks to ensure the safety of the work crew. This practice is followed to prevent any unauthorized access or operation of machinery or equipment. By allowing each person to attach their own lock, it ensures that each individual has control over their own safety and that no one can remove the lock without their knowledge. Therefore, the statement that only one person is allowed to attach a single lock for the entire work crew is false.

Explanation
Even after equipment has been isolated from its power sources, there may still be residual energy stored in the system. This residual energy can pose potential hazards if not properly controlled. Therefore, it is necessary to control any energy stored in the system to ensure the safety of individuals working on or around the equipment.

Explanation
When testing equipment to verify that it has been isolated from its energy sources, it is important to shut off all machine controls to ensure that the equipment remains in a safe and non-operational state. By shutting off the machine controls, any potential accidental activation or unintended movement of the equipment can be prevented, reducing the risk of accidents or injuries. Therefore, the statement "you must be sure to shut off all machine controls" is true.

Explanation
Once energy isolation and lockout/tagout have been applied, it ensures that the equipment is completely de-energized and cannot be re-energized while you are working on it. This is done by disconnecting the power source, locking it out, and placing a tag on it to indicate that it should not be operated. These measures are taken to prevent unexpected energization and protect workers from electrical hazards, making the statement true.

Explanation
Before removing lockout/tagout devices, it is crucial to ensure that the danger area is clear of tools and workers. This is because removing these devices without ensuring the area's safety can lead to potential accidents or injuries. By confirming that there are no tools or workers present in the danger area, the risk of harm is minimized, making the statement true.

Explanation
When contractors perform maintenance in your workplace, you will not be required to change your lockout/tagout procedure. This is because lockout/tagout procedures are in place to ensure the safety of employees working on or near equipment that is being serviced or repaired. Contractors are typically responsible for following their own safety protocols and procedures, which may differ from the lockout/tagout procedure used by the regular employees. Therefore, there is no need to change the lockout/tagout procedure when contractors are involved.

Explanation
When working on equipment, it is important to ensure that the energy is isolated and locked out/tagged out to prevent any unexpected re-energization. This is because re-energizing the equipment without proper isolation can pose serious safety risks to the workers. Therefore, as soon as the energy is no longer needed in the system, it is necessary to re-apply energy isolation and lockout/tagout measures to maintain a safe working environment.

Explanation
If a worker is not present, no co-worker can remove his lock without ensuring it is safe. This means that only the worker who placed the lock can remove it, as they are responsible for ensuring the safety of the equipment or area. Therefore, the statement that any co-worker can remove the lock is false.
