How can you stop yourself from falling over the edge while working on a flat roof?
- A.
Put a large warning sign at the edge of the roof
- B.
Ask someone to watch you and shout when you get too close to the edge
- C.
Protect the edge with a guard-rail and toe-board
- D.
Use red and white tape to mark the edge
Correct Answer
C. Protect the edge with a guard-rail and toe-boardExplanation
To prevent oneself from falling over the edge while working on a flat roof, the best solution is to protect the edge with a guard-rail and toe-board. This safety measure creates a physical barrier that acts as a protective boundary, reducing the risk of accidental falls. By installing a guard-rail and toe-board, workers can confidently move around the roof, knowing that they have a secure barrier in place to prevent them from accidentally stepping over the edge. This solution is more reliable and effective compared to relying on warning signs, someone watching, or tape markings alone.Rate this question:

How many people should be on a ladder at the same time?
- A.
2
- B.
1
- C.
1 on each section of an extension ladder
- D.
3 if it is long enough
Correct Answer
B. 1Explanation
The correct answer is 1 because it is generally recommended that only one person should be on a ladder at a time to ensure safety and stability. Having more than one person on a ladder can increase the risk of accidents or the ladder becoming unbalanced. It is important to follow safety guidelines and use ladders properly to prevent injuries.Rate this question:

How to ensure that a ladder is safe and won't slip?
- A.
Tie at the top
- B.
Ask someone to stand with their foot on the bottom rung
- C.
Tie it at the bottom
- D.
Wedge the bottom of the ladder with blocks of wood
Correct Answer
A. Tie at the topExplanation
To ensure that a ladder is safe and won't slip, tying it at the top is the correct answer. By securing the ladder at the top, it will have more stability and reduce the risk of it sliding or falling. This prevents any movement or wobbling while using the ladder, providing a safer environment for the person using it. Tying the ladder at the top can be done using ropes or straps, ensuring that it is firmly attached to a stable structure.Rate this question:

You need to use a ladder to get to a scaffold platform. Which of the statements is true?
- A.
It must be tied and extend about five rungs above the platform.
- B.
All broken rungs must be clearly marked.
- C.
It must be wedged at the bottom to stop it slipping.
- D.
Two people must be on the ladder at all times.
Correct Answer
A. It must be tied and extend about five rungs above the platform.Explanation
The correct answer is that the ladder must be tied and extend about five rungs above the platform. This is important for ensuring the stability and safety of the ladder while climbing to the scaffold platform. By tying the ladder, it prevents it from slipping or moving while in use. Extending the ladder about five rungs above the platform provides a secure handhold for the person climbing up or down, reducing the risk of accidents or falls.Rate this question:

When you climb a ladder, you must:
- A.
Have three points of contact with the ladder at all times
- B.
Have two points of contact with the ladder at all times
- C.
Use a safety harness
- D.
Have two people on the ladder at all times
Correct Answer
A. Have three points of contact with the ladder at all timesExplanation
When climbing a ladder, it is important to have three points of contact with the ladder at all times. This means that two hands and one foot, or two feet and one hand, should be in contact with the ladder to ensure stability and prevent falls. Having three points of contact distributes the weight evenly and allows for better balance while climbing. It is a safety measure that helps to minimize the risk of accidents and ensures a secure ascent or descent on the ladder.Rate this question:

A mobile tower scaffold must not be used on:
- A.
A paved patio
- B.
Soft or uneven ground
- C.
An asphalt road
- D.
A smooth concrete path
Correct Answer
B. Soft or uneven groundExplanation
A mobile tower scaffold must not be used on soft or uneven ground because it can result in instability and pose a safety risk. Soft ground may not be able to support the weight of the scaffold, causing it to sink or tilt. Uneven ground can cause the scaffold to become unbalanced and potentially collapse. It is important to ensure that the ground is stable and level before using a mobile tower scaffold to ensure the safety of workers and prevent accidents. Using the scaffold on soft or uneven ground can lead to serious injuries or even fatalities.Rate this question:

You need to stack materials on a scaffold platform. What is the best way to stop them from falling over the toe-board?
- A.
Put up warning signs on the stack
- B.
Build the stack so that it leans away from the edge
- C.
Fit brick guards
- D.
Cover the stack with netting
Correct Answer
C. Fit brick guardsExplanation
The best way to stop materials from falling over the toe-board on a scaffold platform is to fit brick guards. Brick guards are protective barriers that are installed along the edges of the platform to prevent objects from falling off. They create a physical barrier that keeps the materials in place and ensures the safety of workers below. This solution is more effective than putting up warning signs, building the stack to lean away from the edge, or covering the stack with netting, as brick guards provide a stronger and more reliable means of preventing accidents.Rate this question:

It is safe to cross a fragile roof if you:
- A.
Walk along the line of bolts
- B.
Can see fragile roof signs
- C.
Don't walk on any plastic panels
- D.
Use crawling boards
Correct Answer
D. Use crawling boardsExplanation
Using crawling boards is the safest way to cross a fragile roof because they distribute weight evenly and provide a stable surface to walk on. Walking along the line of bolts may not guarantee safety as the roof may still be weak in other areas. Seeing fragile roof signs is helpful, but it does not ensure safety unless proper precautions are taken. Avoiding walking on plastic panels is important as they may not be able to support weight. Therefore, using crawling boards is the best option to minimize the risk of falling through a fragile roof.Rate this question:

You need to work at height. It is not possible to install edge protection or a soft landing system. What should you do?
- A.
Hold onto something while you use your other hand to do the work
- B.
Ask someone to hold you while you work
- C.
Wear a harness and lanyard and fix it to an anchor point
- D.
Tie a rope around your waist and tie the other end to an anchor point
Correct Answer
C. Wear a harness and lanyard and fix it to an anchor pointExplanation
When working at height without the possibility of installing edge protection or a soft landing system, wearing a harness and lanyard and fixing it to an anchor point is the safest option. This will provide fall protection and prevent any potential accidents or injuries by keeping the worker securely attached to a stable point. Holding onto something while using the other hand to work or asking someone to hold you while working may not provide sufficient protection against falls. Tying a rope around the waist and fixing it to an anchor point may not be as secure or reliable as using a harness and lanyard.Rate this question:

You need to reach the working platform of a mobile tower scaffold. What is the right way to do this?
- A.
Climb up the tower frame on the outside of the tower
- B.
Lean a ladder against the tower and climb up that
- C.
Climb up the ladder built into the tower
- D.
Jump from the rigid structure on which you are working
Correct Answer
C. Climb up the ladder built into the towerExplanation
The correct way to reach the working platform of a mobile tower scaffold is to climb up the ladder built into the tower. This ladder is specifically designed and built for safe access to the platform. It is important to use the designated ladder rather than climbing up the tower frame on the outside or leaning a ladder against the tower, as these methods may not provide the same level of stability and safety. Jumping from the rigid structure on which you are working is also not safe and should be avoided.Rate this question:
