Work at height means work in any place where a fall could cause injury, including below ground level.
Plan the work, use the right equipment, train people, and inspect equipment. Avoid fragile surfaces.
A risk assessment and a method that prefers collective protection over PPE alone are the normal approach.
Check HSE’s work-at-height topic pages for ladders, scaffolds and MEWPs.
