Can anyone tell me if there is any regulation regarding the installation of ladders inside or outside the scaffold structure, I know that if it is a mobile scaffold structure the ladders need to be inside the structure.
I was in the belief that if it is a fixed scaffold structure then it was down to choice inside or outside.

Hi Alan,
You have to balance the risk of getting on and off the ladder it outside, and usually the need to put a gap in platform edge protection to facilitate safe access, i.e. avoiding needing to duck under a guard-rail, against the risk of having an opening in a gangway where the ladder is inside.
The preferred solution is to have one or more access ONLY towers on the outside of the main scaffold, but e.g. on a pavement this may not be practical.
Regards, Peter

Hi Alan,
I agree that a separate access only tower is a good idea.
Where practicable provide stair access instead of ladders to make this option even safer. Eliminates the many hazards associated with ladder use.

Outside or inside is fine - but both have problems.
I agree with the last person, GO FOR STAIRS, the justification is easy: will employees be required to carry materials or tools up to the work place? Try carrying tools and materials up a ladder.

Where you do have to use ladders just insist that each one rises no more than a single lift, this will immediately limit the posible fall height to a single lift height. If you dont make this requirement explicit most scaffolders will erect ladders rising 3, 4 or even 5 lifts with the possibility of a major fall. If you look at erection access ladders on scaffolds you will be amazed, or maybe not, at the manner of use of ladders by scaffolders.
Access towers are essential if using short ladders and I have yet to find a site where they cannot be erected even in city centres.
Overall however it should be recognised that if you can get an access tower in you can also fit a staircase in the tower.

In the good old days the bottom ladder was always outside the scaffold. This was to allow for the control of access to the scaffold. The ladder could be removed at night and weekends to stop children etc climbing the scaffold.
Such control measures are very important.
The longest ladders can be up to 9 meters long.
Good Luck

All good references, especially BS Standards

When erecting a mobile tower the access is always from the inside of the tower, as per the operators guide from PASMA, the chief association for mobile towers.
hope this helps
