LA455 is a completely revised document for assessing risks when using Ladders and Stepladders. It supersedes the previous Brief Guide INDG455 from the Health & Safety Executive, UK.
Ladders and stepladders are not banned under health and safety law. In fact they can be a sensible and practical option for low-risk, short- duration tasks.
This guidance is for employers on the simple, sensible precautions they should take to keep people safe when using ladders and stepladders in the workplace. This will also be useful for employees and their representatives.
Following this guidance is normally enough to comply with the Work at Height Regulations 2005 (WAHR). You are free to take other action, except where the guidance says you must do something specific.
