2.2 Handling of ladders
2.2.1 Care in handling and setup
Ladders should not be dropped, jarred or misused. Before a ladder is to be raised, lowered or carried, risks associated with the task should be assessed. These risks include the following:
(a) Slope, strength and friction of the supporting surface.
(b) Height and reach required
(c) Environmental conditions.
(d) Work areas, e.g. adequate space available to handle and set up the ladder.
d) Manual handling.
(e) Potential for contact with persons or objects within the swing or fall radius of the ladder. A device to assist or more than one person may be needed to handle and set up the ladder. The ladder should remain under the control of the person or persons handling the ladder at all times.
When a ladder is being raised, lowered or carried, encroachment of any exclusion zones, such as distance to powerlines, and contact with any person or object in the vicinity, should be avoided.
2.2.2 Care during transport
Where a ladder is being transported by a vehicle, including push carts or trolleys, the ladder should be supported to avoid sagging. Overhang of the ladder beyond supporting points should be limited. Ladder supports should be made of material that will not damage the ladder and has enough friction to prevent sliding, e.g. wood or rubber-covered metal. The ladder should be securely fastened to the supports to minimize chafing and the effects of road shock.
When a ladder is being transported on edge (i.e. with treads or rungs vertical]), the ladder should be supported under the lower stile to prevent springing of the rungs.
2.3 Pitch angle
Portable non-self-supporting ladders should be pitched at an angle of 4:1, i.e. set the base 1 m out from the wall for every 4 m it reaches up (see Figure 2.2). AS 1892.5 pdf download.
