Before removing lockout/tagout devices, you must make sure the danger area is clear of tools and workers.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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 confirming the absence of potential hazards can lead to accidents and injuries. By verifying that the area is free from any obstructions or individuals, the risk of harm is minimized, making it essential to prioritize safety protocols before proceeding with lockout/tagout removal.Rate this question:

Before lockout/tagout is applies, all workers in the affected area must be notified.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Before implementing lockout/tagout procedures, it is crucial to inform all workers in the affected area about the process. This notification ensures that everyone is aware of the potential hazards and understands the need for the lockout/tagout procedure to be followed. It also helps to prevent any accidental re-energization of machinery or equipment, which could lead to serious injuries or fatalities. Therefore, it is essential to notify all workers before implementing lockout/tagout.Rate this question:

Once you have isolated a system from its main power source, you can be sure no energy will reach the equipment.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because even when a system is isolated from its main power source, there may still be residual energy stored in the equipment or in other connected devices. Additionally, some equipment may have backup power sources or batteries that can continue to supply energy even when disconnected from the main power source. Therefore, it cannot be guaranteed that no energy will reach the equipment once it is isolated from the main power source.Rate this question:

Select the correct answer: Lockout/tagout is necessary whenever you are performing service or maintencance around any machine where you could be injured by:
- A.
Unexpected start-up of the equipment
- B.
Release of stored energy
- C.
All of the above
Correct Answer
C. All of the aboveExplanation
Lockout/tagout is necessary whenever you are performing service or maintenance around any machine where you could be injured by unexpected start-up of the equipment or release of stored energy. This means that both scenarios pose a potential risk for injury, and it is important to take precautions to prevent accidents. By implementing lockout/tagout procedures, such as de-energizing the equipment and placing locks or tags to prevent it from being started, workers can ensure their safety while working on or near machines.Rate this question:

Which answer can best be defined as "the force caused by the motion of an object"
- A.
Kinetic energy
- B.
Potential energy
- C.
Latent energy
Correct Answer
A. Kinetic energyExplanation
Kinetic energy can best be defined as "the force caused by the motion of an object." When an object is in motion, it possesses kinetic energy. The amount of kinetic energy an object has depends on its mass and velocity. As the object's speed increases, its kinetic energy also increases. This energy is transferred from the object to other objects or can be converted into other forms of energy. Therefore, kinetic energy is the most appropriate answer to the question.Rate this question:

Which answer can best be defined as "the force stored in an object that isn't moving"
- A.
Potential energy
- B.
Latent energy
- C.
Kinetic energy
Correct Answer
A. Potential energyExplanation
Potential energy can best be defined as "the force stored in an object that isn't moving." Potential energy is the energy possessed by an object due to its position or condition. It is stored energy that has the potential to do work when released. When an object is not in motion, it can still possess potential energy based on its position or state, such as gravitational potential energy or elastic potential energy. Therefore, potential energy is the most suitable answer for the given definition.Rate this question:

When contractors perform maintenance in your workplace, you will be required to change your lockout/tagout procedure.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When contractors perform maintenance in your workplace, you will not be required to change your lockout/tagout procedure. The lockout/tagout procedure is a safety protocol used to ensure that machinery and equipment are properly shut off and not accidentally started during maintenance or repair. This procedure is typically consistent regardless of who is performing the maintenance, whether it is an employee or a contractor. Therefore, the statement that you will be required to change your lockout/tagout procedure when contractors perform maintenance is false.Rate this question:

If you have to temporarily re-energize equipment while you're working on it, you must re-apply energy isolation and lockout/tagout as soon as energy is no longer needed in the system.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When working on equipment, it is important to ensure that energy sources are isolated and locked out or tagged out to prevent accidental startup. This question states that if you have to temporarily re-energize the equipment while working on it, you must re-apply energy isolation and lockout/tagout as soon as the energy is no longer needed. This is true because re-applying energy isolation and lockout/tagout ensures that the equipment remains safe and prevents any potential hazards or accidents.Rate this question:

Each individual employee can decide whether to use lockout, tagout or both.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement suggests that each individual employee has the choice to use either lockout or tagout, or both, when it comes to workplace safety procedures. However, this is not true. In reality, the decision to use lockout, tagout, or both is determined by the employer based on the specific circumstances and safety requirements of the task at hand. It is not left to the discretion of individual employees.Rate this question:

Before you turn off equipment in order to lock or tag it out, you must know the type of energy it uses, the hazards of that energy and how to control the energy.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Before turning off equipment in order to lock or tag it out, it is crucial to have knowledge about the type of energy the equipment uses, the hazards associated with that energy, and the proper methods to control and manage the energy. This is important to ensure the safety of individuals working on or around the equipment, as well as to prevent accidents and injuries. By understanding the energy source and its potential risks, appropriate precautions can be taken to effectively isolate and control the energy during maintenance or repair work.Rate this question:

Turning off the power switch removes all energy from powered equipment.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Turning off the power switch does not necessarily remove all energy from powered equipment. While it may cut off the electrical supply and stop the flow of current, there could still be residual energy stored in capacitors or batteries within the equipment. Therefore, it is not always true that turning off the power switch removes all energy from powered equipment.Rate this question:

Before removing lockout/tagout devices, you must make sure the danger area is clear of tools and workers.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Before removing lockout/tagout devices, it is crucial to ensure that the danger area is free from tools and workers. This is important to prevent any potential accidents or injuries that may occur when the equipment is being operated or when the devices are removed. By clearing the danger area, it reduces the risk of someone unintentionally starting the machinery while maintenance or repairs are being performed, which can lead to severe consequences. Therefore, it is essential to verify that the danger area is clear before removing lockout/tagout devices.Rate this question:
