CLIFT, L., HARRIS, D. and WEE BEASTY ELECTRONICS, 2006. Evaluating the stability requirements for mounting and dismounting from the top of leaning ladders. Research report 478. London : Health and Safety Executive.
This report details the methodology and findings of an investigation into the suitability of leaning ladders as a means to access high surfaces. This work has been funded by the Health and Safety Executive to provide a factual basis on which to make recommendations regarding safe practice. In particular it addresses a gap in the knowledge generated in previous studies into safe ladder use. This gap is generated by those individuals for whom the pressures of work make use of a ladder necessary but for whom safe practice is compromised. In particular, environmental demands, multiple unpredictable locations and challenging tasks combine to make a ladder an obvious, yet arguably unsafe, choice of equipment.
