One of your co-workers fall off a working surface that is 16' off the ground. How long would it take for them to hit the ground?
- A.
1 second
- B.
.001 seconds
- C.
3 seconds
- D.
4 seconds
Correct Answer
A. 1 secondExplanation
The correct answer is 1 second because the time it takes for an object to fall from a certain height is determined by the acceleration due to gravity, which is approximately 9.8 m/s^2. Using the equation d = 1/2 * g * t^2, where d is the distance fallen, g is the acceleration due to gravity, and t is the time, we can solve for t. In this case, the distance fallen is 16', which is approximately 4.88 meters. Plugging in the values, we get 4.88 = 1/2 * 9.8 * t^2. Solving for t, we find that t is approximately 1 second.Rate this question:

Why should duplex nails never be used for handrail construction?
- A.
The create a snagging hazard on the surface of the handrail
- B.
The aren't as strong as 16d sinkers
- C.
They are fine to use because it will make it easy to dismantle the handrail when we take it down in a week
Correct Answer
A. The create a snagging hazard on the surface of the handrailExplanation
Duplex nails should never be used for handrail construction because they create a snagging hazard on the surface of the handrail. This means that they can catch on clothing or cause injury to someone using the handrail. It is important to use nails that are smooth and won't pose a risk to the safety of individuals using the handrail.Rate this question:

An anchorage point for a Fall RESTRAINT system must be capable of supporting?
- A.
4,000 pounds
- B.
1,500 pounds
- C.
12,000 pounds
- D.
3,000 pounds
Correct Answer
D. 3,000 poundsExplanation
An anchorage point for a Fall RESTRAINT system must be capable of supporting 3,000 pounds. This weight capacity is necessary to ensure the safety of the individual using the system. If the anchorage point cannot support the weight, it may fail, causing the person to fall and potentially suffer serious injuries. Therefore, it is essential to choose an anchorage point that can handle the weight and provide a secure and reliable connection for the Fall RESTRAINT system.Rate this question:

Two fall protection systems that are not usually allowed by the company are:
- A.
Fall arrest
- B.
Monitor system (Controlled access zone)
- C.
Safety Barriers
- D.
Safety net system
Correct Answer(s)
B. Monitor system (Controlled access zone)
D. Safety net systemExplanation
The company does not usually allow the use of the monitor system (controlled access zone) and safety net system as fall protection systems. This suggests that the company has specific guidelines and regulations in place regarding the types of fall protection systems that can be used. It is possible that the company considers these two systems to be less effective or less safe compared to other fall protection systems that they do allow.Rate this question:

The person using a fall protection harness should inspect it______?
Correct Answer(s)
Daily
daily
every day
Every Day
Each DayExplanation
The person using a fall protection harness should inspect it daily, every day, or each day. Regular inspections are necessary to ensure the harness is in good working condition and free from any defects or damage that could compromise its effectiveness in preventing falls. By inspecting the harness daily, the person can identify any issues and take appropriate action, such as repairing or replacing the harness, to maintain their safety while working at heights.Rate this question:

It is okay to use a large rebar or pelican type hook when connecting a lanyard to a horizontal life line?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Using a large rebar or pelican type hook when connecting a lanyard to a horizontal lifeline is not okay. This is because these types of hooks are not designed to be used with a lanyard and may not provide a secure connection. It is important to use the correct type of hook that is specifically designed for use with a lanyard to ensure safety while working at heights.Rate this question:

An employee is working on a wall 16' tall and is tied off at chest level. What happens if the employee falls?
- A.
They will potentially impact the lower level because total calculated fall distance with a 4' lanyard is 16 1/2 feet so we need to design a better system
- B.
Not sure but the employee only weighs 150 pounds so he should be okay.
- C.
We will always make sure the employee ties off above their head so we won't have to worry about fall distances.
Correct Answer
A. They will potentially impact the lower level because total calculated fall distance with a 4' lanyard is 16 1/2 feet so we need to design a better systemExplanation
If the employee falls, they will potentially impact the lower level because the total calculated fall distance with a 4' lanyard is 16 1/2 feet. This means that the length of the lanyard is not sufficient to prevent the employee from hitting the ground. Therefore, a better system needs to be designed to ensure the employee's safety.Rate this question:

It is not okay to store fall protection harnesses in a tool/gang box?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Storing fall protection harnesses in a tool/gang box is not okay because it can lead to damage or contamination of the harnesses. Fall protection harnesses are safety equipment that need to be properly maintained and stored in a clean and dry environment to ensure their effectiveness. Storing them in a tool/gang box, which may contain sharp tools, chemicals, or other potentially damaging substances, can compromise the integrity of the harnesses and put the user at risk during a fall. Therefore, it is true that it is not okay to store fall protection harnesses in a tool/gang box.Rate this question:

All lanyards can be used to tie back to themselves to help create an anchor point.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because not all lanyards can be used to tie back to themselves to create an anchor point. While some lanyards may have a loop or other feature that allows for self-tying, not all lanyards are designed this way. Some lanyards may have a specific attachment point or require an additional piece of equipment to create an anchor point. Therefore, it is incorrect to say that all lanyards can be used in this manner.Rate this question:

If an employee falls into their fall protection equipment what should happen to the equipment.
- A.
Inspect it and return to service if it is in good condition
- B.
If the employee was injured save the components to help with the investigation
- C.
If the employee was not injured cut it up and throw it away
- D.
Save the equipment and only use it when you think someone might fall. It worked the first time so it should work the second time.
Correct Answer(s)
B. If the employee was injured save the components to help with the investigation
C. If the employee was not injured cut it up and throw it awayExplanation
If an employee falls into their fall protection equipment, the correct course of action would be to save the components of the equipment if the employee was injured. This is important to help with the investigation into the incident and determine the cause of the fall. However, if the employee was not injured, the equipment should be cut up and thrown away. This is because the equipment may have been compromised during the fall and may not provide adequate protection in the future. Saving and reusing the equipment is not recommended as it may not be reliable after a fall.Rate this question:

When must a soft stop be used?
- A.
When you want to add 3.5 feet to your free fall distance
- B.
When you think the person might fall
- C.
Any time we are working on a leading edge
- D.
Whenever we believe it would help minimize the impact of a fall to employees body.
Correct Answer
C. Any time we are working on a leading edgeExplanation
A soft stop must be used whenever we are working on a leading edge. This is because working on a leading edge involves a higher risk of falling, and a soft stop can help minimize the impact of a fall on the employee's body. It provides a cushioning effect and reduces the chances of severe injuries. Therefore, using a soft stop in such situations is essential for ensuring the safety of the workers.Rate this question:
