Control measures
The Work at Height Regulations (2005) set out a hierarchy of measures which must be considered when carrying out a risk assessment for any work activity involving working at height. Preference must be given to the first measure of the hierarchy, only moving down the list if each measure is not reasonably practicable.
The hierarchy of control measures, from most preferable to least preferable:
- Avoid carrying out work at height (for example, using long-handled tools to clean windows or trim hedges)
- Use existing safe places of work or means of access or egress (for example, fixed platforms or stairways)
- Use adequate work equipment to prevent a fall (for example, scaffolding, scaffold tower, mobile elevating platforms)
- Minimise the distance and/or consequences of a fall (for example, using fall arrest equipment such as harnesses, safety nets or air bags)
