Lockout/Tagout Control Of Hazardous Energy Quiz

Explanation
During servicing or maintenance, various energy sources such as electrical, mechanical, or thermal may be present. If not properly controlled, these energy sources can be released unexpectedly, leading to accidents and injuries. Therefore, the statement that the unexpected release of energy is a major hazard during servicing or maintenance is true.

Explanation
The given statement is true. OSHA estimates that lockout/tagout protects approximately 3.3 million employees each year. This means that the implementation of lockout/tagout procedures helps to prevent accidents and injuries in the workplace, ensuring the safety of a significant number of employees.

Explanation
An Authorized Employee is a person who has the authority and knowledge to lock out machines or equipment. This means they have been trained and authorized to perform lockout procedures, ensuring the safety of themselves and others. Therefore, the statement that a person who locks out machines or equipment is an Authorized Employee is true.

Explanation
An authorized employee is someone who has been given the authority and responsibility to lock out or tag out machines or equipment in order to perform servicing or maintenance on them. This ensures that the machines or equipment are safely shut down and cannot be accidentally started or operated while maintenance work is being done. By having authorized employees perform these tasks, it helps to prevent accidents and injuries that could occur if someone without proper training and authorization were to attempt servicing or maintenance on the machines or equipment. Therefore, the statement "A person who locks out or tags out machines or equipment in order to perform servicing or maintenance on that machine or equipment is called an Authorized Employee" is true.

Explanation
The statement is false because the four main types of energy discussed are electrical, mechanical, hydraulic, and thermal, not turbine.

Explanation
When a machine is turned off, it may still have residual energy or power running through it. This residual energy can be in the form of stored electricity in capacitors or batteries, or it can be in the form of mechanical energy in moving parts. Therefore, turning off a machine does not guarantee that all energy to the machine has been stopped. Hence, the statement "Turning off a machine does not necessarily stop all energy to the machine" is true.

Explanation
Lockout is a safety procedure used to prevent the accidental or unauthorized starting of equipment. It involves the use of locks or tags to physically disable the equipment and ensure that it cannot be operated. This is done to protect workers from potential hazards or injuries that could occur if the equipment were to start unexpectedly. Therefore, the statement "Lockout is a means of keeping equipment from being started" is true.

Explanation
The given statement is false. Lockout is not just turning a machine off and unplugging it before performing maintenance. Lockout is a safety procedure that involves isolating a machine or equipment from its energy source and ensuring that it cannot be operated or energized during maintenance or repair work. This is done by using lockout devices such as locks, tags, or other physical barriers to prevent accidental or unauthorized use of the machine. Simply turning off and unplugging a machine is not sufficient to ensure the safety of maintenance workers.

Explanation
Locks used for lockout are specifically designed and designated for the purpose of lockout. These locks are typically durable and have unique features that prevent them from being used for any other purpose. They are often brightly colored or labeled with warnings to indicate their purpose and to ensure that they are not mistakenly used for other applications. This ensures the safety and effectiveness of lockout procedures by providing a clear visual indication that a piece of equipment or machinery is locked out and should not be operated. Therefore, the statement that locks used for lockout can only be used for lockout and nothing else is true.

Explanation
The statement is true because standardizing locks within a facility by color, size, or shape helps to ensure consistency and efficiency in managing and using the locks. It allows for easy identification and differentiation of locks, making it easier for staff to locate the correct keys and use them on the appropriate locks. Standardization also helps to prevent confusion and potential security breaches that could occur if locks were not uniform throughout the facility.

Explanation
Tags do not physically lock out energy, but they serve as a warning or cautionary measure to indicate potential dangers. They are used to provide information about hazards or risks associated with certain objects, substances, or areas. By displaying appropriate tags, individuals can be alerted to the presence of potential hazards and take necessary precautions to ensure their safety. Therefore, the statement that tags don't lock out energy but only warn of the dangers is true.

Explanation
Employers must have a written policy that defines the lockout process because it is crucial for ensuring the safety of employees. A written policy provides clear guidelines and instructions for implementing lockout procedures, which involves isolating energy sources to prevent accidental startup of machines or equipment. This policy helps to minimize the risk of workplace accidents and injuries caused by unexpected release of energy. Additionally, a written policy ensures consistency in lockout procedures across the organization and helps to train employees on proper lockout practices.

Explanation
The statement is true because the lockout process indeed consists of six steps. These steps are followed to ensure the safety of workers when working on machinery or equipment that may have stored energy. The process involves preparation, shutdown, isolation, lockout, verification, and release of energy. Each step is crucial in preventing accidents and injuries by effectively controlling hazardous energy sources.

Explanation
Before starting work on a locked-out machine, the authorized employee must confirm that the energy to the machine has been isolated. This is an important safety measure to prevent any accidental release of energy that could cause harm or injury to the employee or damage to the machine. By confirming the isolation of energy, the authorized employee ensures that it is safe to work on the machine without any potential risks. Therefore, the statement "Before starting work on a machine that has been locked out, the Authorized Employee must confirm the isolation of energy to the machine" is true.

Explanation
Lockout and tagout are two separate procedures used to ensure the safety of workers when performing maintenance or repairs on machinery or equipment. Lockout involves physically disconnecting the power source and securing it with a lock, while tagout involves using a tag to indicate that the equipment is not to be operated. Both procedures are important for worker safety and should be used in conjunction with each other. Therefore, the statement that tagout can be used instead of lockout whenever the employer wants is false.

Explanation
The statement means that only the employees who have been authorized and have applied the lockout device are allowed to remove it. This is done to ensure safety and prevent any unauthorized access or tampering with the lockout devices. By limiting the removal of lockout devices to authorized employees, there is a higher level of control and accountability, reducing the risk of accidents or incidents during maintenance or repair work. Therefore, the answer is true.

Explanation
A lockout device is used to ensure the safety of employees by preventing the operation of machinery or equipment while maintenance or repairs are being carried out. It is typically placed by the employee performing the work. However, if the employee is not present, the employer may need to remove the lockout device in order to resume operations. This is done under strict protocols and only after ensuring that it is safe to do so. Therefore, the statement that a lockout device can be removed by an employer when the employee that placed the device is not present is true.

Explanation
In a group lockout, one crew member is assigned the primary responsibility of coordinating and overseeing the lockout process. This crew member is responsible for ensuring that all necessary steps are taken to safely lock out equipment or machinery, and that all crew members are aware of and follow the lockout procedures. This helps to ensure that the lockout process is properly executed and that everyone involved is on the same page, reducing the risk of accidents or injuries.

Explanation
Continuity of protection between work shifts during group lockout is necessary to ensure the safety of workers. Group lockout involves multiple workers performing maintenance or repairs on equipment or machinery. If there is a shift change during the lockout process, it is crucial to maintain the lockout measures in place to prevent accidental energization of the equipment. This ensures that all workers involved are aware of the lockout status and can safely continue the maintenance or repair work without any risk of injury. Therefore, the statement is true.

Explanation
The statement is true because the on-site employer has a responsibility to ensure that their employees are aware of and follow the restrictions outlined in the outside employer's energy control program. This program is designed to protect employees from hazardous energy sources and prevent accidents or injuries. By ensuring compliance, the on-site employer can maintain a safe working environment and prevent potential risks or violations.
