IPAF Ground Conditions and Stability

Question 1

Before positioning a MEWP, what must be assessed about the ground conditions?

Accepted Answer

The load-bearing capacity, levelness, presence of voids or underground services, and surface condition

Answer

Only whether the ground is dry

Answer

Whether the ground matches the colour scheme of the MEWP

Answer

Only whether the ground is concrete or tarmac

Question 2

What is the primary risk of operating a MEWP on ground that is not level?

Accepted Answer

The machine may overturn due to the shifted centre of gravity

Answer

The paint may get scratched

Answer

The battery will drain faster

Answer

The controls will operate in reverse

Question 3

What precaution must be taken when positioning a MEWP near an excavation or trench?

Accepted Answer

Maintain a safe distance equal to at least the depth of the excavation from the edge, to prevent collapse

Answer

Park as close as possible for easier access to the trench

Answer

Position the outriggers over the edge of the excavation

Answer

No special precautions are needed if the MEWP is on tracks

Question 4

Why are spreader plates used under MEWP outriggers?

Accepted Answer

To distribute the point load over a larger area, preventing the outrigger from sinking into soft ground

Answer

To make the MEWP look more professional

Answer

To raise the height of the MEWP

Answer

To prevent scratching the floor surface

Question 5

A MEWP is to be used on a suspended floor (such as a car park deck). What additional assessment is required?

Accepted Answer

The structural load capacity of the floor must be confirmed by a competent person before the MEWP is positioned

Answer

No additional assessment — all floors can support MEWPs

Answer

Only the colour of the floor markings needs checking

Answer

The MEWP hire company will assess this automatically

Question 6

What is the danger of positioning a MEWP over an underground service such as a drain or utility cover?

Accepted Answer

The cover or ground above the service may collapse under the concentrated weight of the MEWP or outrigger

Answer

The service cover may be too slippery

Answer

The underground service may cause electromagnetic interference

Answer

There is no danger as services are designed to bear heavy loads
