Safety Lifelines

A safety lifeline is a flexible line that connects a worker’s harness to an anchorage point, allowing freedom of movement while preventing falls. It acts as a link between the worker and the anchor system, absorbing or arresting the force if a fall occurs. Lifelines can be horizontal or vertical, depending on the work environment. They are essential components of a complete fall protection system.

A lanyard is a fixed-length connector between a harness and an anchor, typically six feet or less in length. A lifeline, on the other hand, provides longer range and flexibility, allowing vertical or horizontal movement while maintaining continuous connection. Lanyards often include shock absorbers, while lifelines can integrate retractable or rope-based designs. Both serve to minimize fall risk but differ in range and use.

The lifespan of life safety rope depends on usage, environment, and manufacturer guidelines. Generally, ropes should be retired after 10 years even if unused, or sooner if exposed to chemicals, sharp edges, heavy loads, or visible damage. Regular inspection before and after each use is crucial. Replace immediately if there is fraying, discoloration, or loss of elasticity.

OSHA standards require that lifelines be made of materials with sufficient strength and durability to support fall arrest loads. Vertical lifelines must have a minimum breaking strength of 5,000 pounds per worker attached. Horizontal lifelines must be designed, installed, and used under the supervision of a qualified person. All lifeline systems should be inspected before each use to ensure safety compliance.

The three main types are horizontal, vertical, and self-retracting lifelines. Horizontal systems run between two anchors and allow workers to move laterally while remaining connected. Vertical lifelines, such as those found in vertical lifeline systems, move up and down with the worker. Self-retracting lifelines, found in our SRL collection, automatically extend and retract for smooth, tangle-free movement.

Most lifelines use synthetic fibers like polyester or nylon, chosen for their high strength, flexibility, and resistance to abrasion and UV damage. Polyester is preferred for its low stretch and superior weather resistance, while nylon offers elasticity to absorb shock loads. Some systems use steel cable lifelines for added durability in rugged or industrial settings. The correct choice depends on the job environment and safety requirements.

Start by assessing your work height, mobility needs, and the type of anchorage available. Vertical jobs may require rope-based systems, while horizontal movement benefits from cable or SRL setups. Ensure the lifeline meets ANSI and OSHA standards for strength and design. Always choose a system rated for your specific fall arrest or restraint application.
