Trestle Scaffolds allow access to work where more than one person is needed or where
access is necessary to a wider area than a ladder could reach.

They should be regarded in the same way as Ladders or Step Ladders – for temporary and
lightweight use only.

If heavyweight or long term access is required then proper scaffolding of tubes and boards or
mobile tower must be provided.

The Regulations, concerning Trestle Scaffolds are the same as those for other access
equipment regarding strength, condition, stability etc.

Trestle Scaffold Rules

o A Trestle Scaffold is not permitted to have the deck at a height of more than 4.5 metres according to Regulation 21.2a.
  
o If the Trestle Scaffold is erected near an edge then the 4.5 metre height limit  is measured from the lowest level.

o The decking should be no more than two thirds up the height of the Trestle Scaffold.

o Proprietary decking will have a label attached stating maximum loading, span and possibly the maximum number of persons – DO NOT EXCEED.

o The platform must be at least 635mm wide and more than 635mm wide if materials are to be deposited on it.

o Where the platform is made of planks, the following guide as to maximum span should be followed: 
    38mm planks (1½”)  1.5m
    50mm planks (2”)  2.5m
    65mm planks (2½”)  3.0m

o Access to the staging should be by an adjacent Step Ladder.  DO NOT climb up the trestles.

o A Trestle Scaffold must NEVER be used as a substitute for a Step Ladder – the horizontal bars are too far apart and this type of use is dangerous and not the way it was intended. 

o Check that there are no loose or missing screws and bolts, no splits, warping or decayed or broken parts.  It could be your neck that gets broken if it collapses.

o Report any defective Trestle Scaffold immediately. Ensure that the Trestle Scaffold is labelled and taken out of commission.
