The ABC’s

A simple way of remembering the core components of a fall arrest system is the “ABC” of Fall Arrest. Quite simply, without one part, the system does not work.

Anchor Devices

Definition : Used to join the connecting device (work restraint, fall arrester) to the anchorage, commonly referred to as the “tie-off point” (I-beam, scaffolding or other structural point).

Anchor devices may be one of the 2 types :

• Permanent anchor devices (e.g. horizontal cable lifeline, horizontal rail systems...).
• Temporary anchor devices (e.g. steel strops, scaffold hooks, webbing anchorage slings, beam grips and dead-weight anchor...).

Full Body Harness

Definition : Used to hold a worker during & after a fall.

• Full body harness must be worn for Fall Arrest situations.
• Work restraint belts cannot be used for Fall Arrest.

Connecting Devices

Definition : Used as intermediate attachment to connect the worker’s harness to the anchor device (e.g. shock absorbing lanyard, self retracting lifeline, fall limiter, rope grab etc.).

Connecting devices may be one of the 2 types :

• Fall Restraint : a fall restraint system prevents workers from reaching a hazard.
• Fall Arrest : a fall arrest system allows workers to reach a hazard and then protects them if they should fall.
