10 pieces of advice on setting up ladders

Ladders must always be put up properly, i.e. on a firm, flat surface
Always check to make sure the ladder is in order, e.g. to make sure that the rungs are not broken.
If you use ladders for access, they must be put up at the angle described in the instructions for use.
75 degrees is always a correct slope.
Ladders used for access must be secured and reach 1 m up over the access point.
Make sure that the ladder is supporting equal amounts of weight on all its legs.
Do not put up the ladder in front of doors or windows as there is a risk of these being opened.
Use trestle ladders where possible.
Use ladders with horizontal, broad steps.
Ladders to be placed up against masts or similar must be provided with suitable support
