Positioning and Erecting the Ladder
General
The ladder should be extended with the rungs or
■
treads level with the ground.
The ladder must be erected on a firm, unmovable
■
surface with a maximum gradient of 15°.
When positioning the ladder, take into account the
■
risk of collision with the ladder (e.g. from pedestrians,
vehicles or doors).
Identify any electrical risks in the work area, such as
■
overhead lines or other exposed electrical equipment.
The ladder should be stood on both feet; not supported
■
on the rungs or steps.
Ladders should not be positioned on slippery
■
surfaces — such as ice, shiny surfaces or significantly
contaminated solid surfaces — unless additional
effective measures are taken to prevent the ladder
slipping or ensuring contaminated surfaces are
sufficiently clean.
Safety Step Platforms
It is recommended that the platform ladder is
■
positioned on level ground or deploy the TerrainMaster
legs to ensure level bubble is within circle.
Extension & Single Ladders
It is recommended that the ladder is positioned at
■
the correct working angle of 75°.
To ensure correct angle, use the angle indicator marked
■
on the rail and/or the level-bubble in the TerrainMaster
base. This position is often referred to the 4:1 rule where
the feet of the ladder are one unit out from the vertical
contact surface for every 4 units measured vertically to
the point of contact of the ladder to the vertical surface.
