A lifeline is a fall protection system that allows workers to move safely in elevated areas (such as roofs, scaffolding, or metal structures) while remaining secured. The worker connects using a full-body harness to a cable or rail anchored to the structure.
Main Components
- Cable or rail (horizontal or vertical): the path along which the worker moves.
- Anchorage points: fixed points where the lifeline is secured.
- Energy absorbers: reduce the impact force in the event of a fall.
- Trolley or sliding connector: links the worker to the cable.
- Full-body harness.
Types of Lifelines
- Horizontal: Cable or rail installed parallel to the ground. Used on roofs, beams, etc.
- Vertical: Installed on ladders or tall structures. Allows safe ascent and descent.
- Fixed: Permanent installation in areas with frequent work at height.
- Temporary: Mobile installation for short-duration projects.
Standards and Requirements
- Spain: UNE-EN 795, Royal Decree 2177/2004.
- Lifelines must be designed, installed, and certified by competent personnel.
Best Practices
- Daily inspection of equipment.
- Proper training for all personnel.
- Risk assessment before beginning work.
- Mandatory use of full-body harness with double lanyard.
- Never use improvised anchorage or unstable structures.
