AS 1892.5:2020 pdf free download – Portable ladders Part 5: Selection, safe use and care.
AS 1892.5 sets out the minimum requirements and recommended safe practices for the selection. use and maintenance of portable ladders.
The requirements of this Standard need not apply where safe work procedures that are equivalent or superior to this Standard are in place.
1.2 Application
General recommendations common to the selection, use and maintenance o( portable ladders are given in Section 2. while specific recommendations and requirements for ladders predominantly constructed from a particular material are given In the following Sections:
(a) Metal ladders, see Section 3.
(b) Non-metal ladders, see sctitn4.
(c) Timber ladders, sec Section S.
Section 2 shall be read In conjunction with the relevant Section relating to the type ouladder being used,
1.3 Normative references
There are no normative references In this document.
NOTE Documents referenced for informative purposes are listed In the Bibliography.
1.4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
competent person

indicates the existence of an option
indicates that a statement is mandatory
Indicates a recommendation
The top of the ladder should not be supported by the rungs. Where the tap of the ladder is to be supported against a pole, tree or similar structure that may result in rung loading, It should be fitted with a pole chain, strap, hoop or other suitable device to transfer the support load to the stiles.
The top of the ladder should be secured in position as soon as Is practicable before use.
NOTE 2 Care is needed when securing the top alan extension ladder with clutches that rely on gravity acting on the upper section(s) of the ladder to keep the clutch mechanism engaged. If the support at the top of the ladder Is able to move as the user’s weIght moves LIP the ladder, the top ladder section can be pulled away from the bottom section and the dutch may separate from the rungs, potentially disengaging and causing the ladder to drop down to a lower clutch engagement position. This may cause the ladder to lose connection with the support. Also, in some designs the sljde guide connecting the upper and lower ladder sections may fail and allow the ladder to hinge in a scissor action.
NOTE 3 A similar problem may occurwhcn loweringan extension laddvrintoa wcll,cavityora lowerroolsection whereby the clutch may fully or partly disengage, resulting in a failure when ascending or descending the ladder.
NOTE 4 In situations where the bottom and top sections of an extension ladder can move in a way to extend the ladder, the clutch engagement may not be reliable.
2.6 Using a ladder to gain access
Where a ladder is used to gain access onto a work area or root, the stiles of the ladder should extend above the level of the work area or roof by not less than 1 m. The ladder should be secured at the top before the user transitions from the ladder onto the working platform or roof to prevent sidewards slipping or movement away from the top support.
Care should be taken when transitioning between the ladder and the landing as a need to swing around the stile during the transition increases the potential for slipping or falling.
NOTE 1 In some cases, the ladder could be installed so that it can be accessed from the side.
NOTE 2 In some cases, stile extensions could be Incorporated to allow the user to pass between the stiles when transitioning. Where stile extensions are used, the top rung should b lrvcl with or immediately below the landing so as not to create a trip hazard when passing between the stiles.
2.7 Climbing ladders
When ascending or descending a ladder, the user should face the ladder and be able to grip the ladder with both hands, The use of a tool pouch, or similar, should be considered when carrying tools.
Users should have at least one foot and one hand contact with the ladder while ascending or descending the ladder. The user should not climb or move laterally from one ladder to another.
NOTE For ladders without stiles (I.e. work platforms), It is not expected that a hand will be used to grip the ladder, However, It may be necessary to grip an adjacent structure or object for balance.
2.8 Ladders used near door openings
Where a ladder is to be placed near a doorway, the door should be blocked open, locked closed or removed. In addition to guarding the door, appropriate warning signs may be placed or erected.
2.9 Working on ladders
When working on a ladder, the user should remain centred between the stiles and maintain three points of contact.
NOTE 1 Three points of contact in this context means both feet and one other point of Contact such as the waist, upper torso or hand.
