3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
personal fall protection systems
systems of personal fall protection equipment used to fix the position of operator during work at height, climbing and suspension operations and to prevent operator from falling or to suspend the operator safely after falling
3.2
work positioning systems
personal fall protection system that binds the human body near the fixed construction suit by ropes or straps around the fixed structure to prevent falling and enable the operator's hands to perform other operations.
3.3
restraint systems
personal fall protection systems that prevents operator from reaching the area where a fall may occur by limiting the movement of operator
3.4
fall arrest systems
personal fall protection systems that suspends the operator safely in the event of a falling by braking.
3.5
lanyard
rope or strap that connects the harnesses to the anchor in personal fall protection systems
Note: Lanyard generally serves to expand or limit the operator's range of movement and absorb impact energy.
3.6
energy absorber
component that is connected in series between harnesses and anchor to absorb part of the impact energy and reduce the impact force when falling
3.7
retractable type fall arrester
rope or strap that is connected in series between the harnesses and the anchor, with a length that can be extended with the movement of the operator, and which can be locked and braked by a change in speed in the event of a fall
3.8
guided type fall arrester
component attached to the anchor line and triggered by falling action
3.9
harnesses
component that holds personal fall protection systems over the body to support and control the body in the event of a fall to disperse the impact
Note: Harnesses consists of webbing, buckle and other metal parts. Generally, there are full-body harnesses, single-waist harnesses and half-body harnesses.
3.10
primary strap
webbing in a harness that bears the impact force directly
3.11
secondary strap
strap in a harness that does not directly withstand the impact force
3.12
deploy distance
vertical distance from the test anchor to the lowest point of torso test mass when the fall is stopped during the test
3.13
fall distance
the maximum vertical distance from the start of fall or operation surface to the lowest point of the body of personal fall protection system wearer
3.14
safety space
three-dimensional space below the operation surface, without collision damage objects to the falling person
3.15
locking distance
movement distance of guided type fall arrester on guide line or extended distance of lanyard from the retractable type fall arrester cavity during the test of guided type fall arrester and retractable type fall arrester (from start to stop the movement)
