Rescue

Minimum breaking strength requirements and calculations for rescue carabiners are set out in National Fire Protection Association standard 1983 Fire Service Life Safety Rope and Equipment. The standard defines two classes of rescue carabiners. Light use rescue carabiners are required to have minimum breaking strengths of 27 kN gate closed, 7 kN gate open and 7 kN minor axis. General use rescue carabiners are required to have minimum breaking strengths of 40 kN gate closed, 11 kN gate open and 11 kN minor axis. Testing procedures for rescue carabiners are set out in ASTM International standard F 1956 Standard Specification of Rescue Carabiners.
