PASMA Tower Inspection Procedures 3

Question 1

What type of event would trigger an unscheduled inspection of a tower scaffold?

Accepted Answer

Exposure to severe weather, accidental impact from a vehicle, or any event that could affect stability

Answer

Any event that could have compromised the tower's structural integrity or stability requires an immediate inspection before further use. This includes storms, high winds, impacts from vehicles or equipment, seismic activity, or extended periods of non-use.

Question 2

What should be checked about the internal ladder access during an inspection?

Accepted Answer

That ladder frames are correctly positioned, rungs are undamaged, and climb path is unobstructed

Answer

Internal ladder frames must be in the correct position as per the manufacturer's instructions, with all rungs intact and undamaged. The climb path through trapdoors must be clear of obstructions, and platforms must be in place at each level.

Question 3

During inspection, what is the significance of checking the manufacturer's label or plate on the tower?

Accepted Answer

To confirm the tower model, maximum height, safe working load, and ensure it matches the instruction manual being followed

Answer

The manufacturer's identification plate provides critical information including the model designation, maximum permissible height, safe working load, and component specifications. This ensures the tower has been erected in accordance with the correct instruction manual.

Question 4

What should an inspector look for when checking the frames of a tower scaffold?

Accepted Answer

That they are free from bends, cracks, corrosion, dents, and that all spigots and locking mechanisms are functioning

Answer

Frames must be inspected for structural damage including bends, cracks, significant corrosion, dents, or deformation. All connection points (spigots, spigot plates) and locking mechanisms (gravity locks, spring clips) must be checked for correct function.

Question 5

How should an inspector check that a tower scaffold is level?

Accepted Answer

Using a spirit level placed on the base frames and checking adjustable legs are correctly set

Answer

A spirit level should be used on the base frames to verify the tower is level in both directions. Adjustable legs or screw jacks should be checked to ensure they are correctly extended and locked to compensate for any ground unevenness.
