  1. What is the correct internal access method for climbing a tower scaffold?

    Answer: Using the built-in internal ladder frames via the trapdoor hatch

    Internal ladder frames with trapdoor platforms provide the safest means of access. External climbing or external ladders can destabilise the tower and expose the operative to a greater fall risk.

  2. What should be done with the trapdoor hatch after climbing through it?

    Answer: Close it to create a full working platform

    The trapdoor must be closed after climbing through to create a complete working platform. An open trapdoor creates a trip hazard and a fall risk, and reduces the effective platform area.

  3. What is the minimum platform width recommended by PASMA for a working platform?

    Answer: 600mm

    The minimum recommended platform width is 600mm (approximately 2 feet). Narrower platforms do not provide adequate space for safe working and increase the risk of overbalancing.

  4. When building a tower adjacent to a building, what must be considered regarding the height-to-base ratio?

    Answer: The ratio must still be maintained unless the tower is tied to the structure

    The height-to-base ratio must always be maintained unless the tower is properly tied into the adjacent structure using appropriate fixings. Simply being near a building does not provide stability.

  5. What is the purpose of the adjustable leg (or screw jack) on a tower scaffold?

    Answer: To allow levelling of the tower on uneven ground

    Adjustable legs or screw jacks allow the tower to be levelled on slightly uneven ground. They must not be extended beyond the manufacturer's recommended limit, and a spirit level should be used to check the tower is plumb and level.

  6. How should components be passed up to the operative assembling the tower?

    Answer: Passed by hand from the interior of the tower or hoisted using a gin wheel

    Components should be passed by hand internally or lifted using a gin wheel or line. Throwing components risks dropping them on people below and can unbalance the operative catching them.
