When using ladders, what does the term "three points of contact" mean?
- A.
The ladder should have a minimum of three rungs
- B.
Leave three contact numbers when using ladders
- C.
You should always have three points of contact with the ladder
- D.

What is meant by the "ONE IN FOUR" rule?
- A.
For every four units of height, the base of the ladder should be one unit from the horizontal
- B.
For every one unit of height, the base of the ladder should be four units from the horizontal
- C.
For every one person on the ladder, there should be four people securing it.
- D.
There should be at least four rungs on the ladder for every one floor in height
Correct Answer
A. For every four units of height, the base of the ladder should be one unit from the horizontalExplanation
The "ONE IN FOUR" rule means that for every four units of height, the base of the ladder should be one unit from the horizontal. This rule ensures proper stability and safety when using a ladder. By maintaining this ratio, the ladder's base remains securely positioned, reducing the risk of it tipping over or causing accidents.Rate this question:

You should always check the weight capacity of the ladders prior to use?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
It is important to check the weight capacity of ladders before using them to ensure safety. Different ladders have different weight limits, and exceeding the weight capacity can lead to accidents and injuries. By checking the weight capacity, you can ensure that the ladder is suitable for the intended use and that it can safely support the weight of the user and any additional equipment or materials. Therefore, it is crucial to always check the weight capacity of ladders prior to use.Rate this question:

Ladders can take any weight as long as you don't overload them for more than five minutes?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Ladders have weight limits that should not be exceeded for safety reasons. Overloading a ladder for more than five minutes can lead to structural failure and accidents. Therefore, the statement that ladders can take any weight as long as you don't overload them for more than five minutes is false. It is important to always follow the weight capacity guidelines provided by the manufacturer to ensure safe usage of ladders.Rate this question:

When using access equipment to ensure safe use, where should you secure it ?
- A.
Secure the top of the equipment to a suitable fixed point
- B.
Secure the base of the equipment to a suitable fixed point
- C.
Secure the centre of the equipment to a suitable fixed point
- D.
Any combination of the above
Correct Answer
A. Secure the top of the equipment to a suitable fixed pointExplanation
To ensure safe use of access equipment, it is important to secure the top of the equipment to a suitable fixed point. This will help to prevent the equipment from tipping over or becoming unstable during use. By securing the top, it ensures that the equipment remains in place and reduces the risk of accidents or injuries. Securing the base or center of the equipment alone may not provide sufficient stability, which is why securing the top is the correct answer.Rate this question:

Safety Barriers are used to keep animals out of the site?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Safety barriers are not used to keep animals out of the site. Safety barriers are typically used to prevent access to hazardous areas or to provide protection against falling or other potential dangers. While safety barriers may indirectly keep animals out of a site by creating a physical barrier, their primary purpose is to protect humans from harm rather than keeping animals out. Therefore, the statement is false.Rate this question:
-

The purpose of safety barriers is?
- A.
To stop the theft of materials
- B.
To keep the site clean
- C.
To keep the site safe and to control unauthorised access
- D.
To stop anyone knocking the ladders over
Correct Answer
C. To keep the site safe and to control unauthorised accessExplanation
Safety barriers serve the purpose of keeping the site safe and controlling unauthorized access. These barriers are put in place to prevent accidents, protect workers and visitors from potential hazards, and ensure that only authorized personnel have access to the site. By restricting entry to designated areas and creating physical barriers, safety barriers help maintain a secure and controlled environment, reducing the risk of injuries and theft.Rate this question:

Who is authorised to check access equipment before use
- A.
Anyone
- B.
The Customer
- C.
A suitably qualified person
- D.
Anyone who has used the equipment before
Correct Answer
C. A suitably qualified personExplanation
A suitably qualified person is authorized to check access equipment before use. This person has the necessary knowledge, skills, and expertise to ensure that the equipment is in proper working condition and safe to use. They are trained to identify any potential hazards or defects that could pose a risk to the user. This ensures that the equipment is checked thoroughly and meets all the necessary safety standards before it is used.Rate this question:

Which FOUR of the following items would be checked before use, on access equipment
- A.
Fit for purpose
- B.
In good working order
- C.
Paintwork
- D.
Maintenance records
- E.
Securing points
- F.
Length of hire
Correct Answer(s)
A. Fit for purpose
B. In good working order
D. Maintenance records
E. Securing pointsExplanation
Before using access equipment, it is important to check if it is fit for purpose, meaning it is suitable for the specific task it will be used for. It should also be in good working order, ensuring that all components and functions are functioning properly. Maintenance records should be checked to ensure that the equipment has been regularly serviced and maintained. Lastly, securing points should be inspected to ensure that the equipment can be safely secured in place during use. The length of hire and paintwork are not relevant factors to check before using access equipment.Rate this question:

If the access equipment appears unsafe or defective, you should be careful when using it, and report it as soon as possible?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
If the access equipment appears unsafe or defective, it is important to prioritize safety and not use it. Using unsafe or defective equipment can lead to accidents or injuries. Instead, one should report the issue as soon as possible to the appropriate authority or person responsible for maintenance and repairs. This ensures that the problem is addressed promptly and that the equipment can be fixed or replaced to prevent any potential harm. Therefore, the statement "you should be careful when using it" is incorrect, as caution should be exercised by not using the equipment until it is deemed safe.Rate this question:

When dismantling and storing access equipment, it should be done with care, so that it can be reused effectively and efficiently?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Dismantling and storing access equipment with care ensures that it can be reused effectively and efficiently. By handling the equipment properly, it reduces the risk of damage or wear and tear, allowing it to be used again without any issues. This not only saves time and money but also promotes sustainability by maximizing the lifespan of the equipment. Therefore, it is important to handle access equipment with care during dismantling and storage.Rate this question:

Working Platforms are best used for First Floor Work, whilst Cherry Pickers are for high, hard to reach locations?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Working platforms, such as scaffolding or scissor lifts, are indeed ideal for first-floor work as they provide a stable and secure platform for workers to perform tasks at a moderate height. On the other hand, cherry pickers, also known as boom lifts, are specifically designed for accessing high and hard-to-reach locations. These machines have extendable arms or booms that can reach significant heights, allowing workers to safely work at elevated areas. Therefore, the statement that working platforms are best used for first-floor work, while cherry pickers are for high, hard-to-reach locations, is true.Rate this question:
