RR478 - Evaluating the stability requirements for mounting and dismounting from the top of leaning ladders

This report evaluates reasonable ladder use and quantifies the demands placed on the ladder system when used to access platforms and surfaces. This method of use is commonly found amongst certain trades such as window cleaning or roofing and places unique challenges to the stability of the ladder. The work described quantifies the needs of the user and goes on to present a means of both modelling the stability provided by a given ladder and undertaking a workshop test. This work builds upon previous peer reviewed research undertaken for the HSE and employs a similar methodology. In combination with this previous work it aims to provide a reliable means for determining safe equipment for use in the field as well as assisting in the development of new and improved access devices.

This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.
