3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 personal fall protection systems
A system of individual fall protection equipment that secures operating personnels’ positions
during operations at height, climbing and suspension operations, prevents them from falling, or
safely suspends them after a fall.
3.2 work positioning systems
An individual fall protection system that uses ropes or belts wrapped around a fixed structure
to bind the human body to the vicinity of a fixed structure to prevent the person from slipping
and allow the operating personnels’ both hands to perform other operations.
3.3 restraint systems
Individual fall protection systems that restrain the range of movement of operating personnels
to prevent them from reaching areas where a fall may occur.
3.4 fall arrest systems
When an operating personnel falls, individual fall protection systems that will safely suspend
the operating personnel through braking.
3.5 lanyard
A rope or strap that connects the harnesses to the anchor in the personal protection systems.
NOTE: lanyard generally serves to expand or restrain the wearer’s range of movement and absorb
the impact energy.
3.6 energy absorber
A component connected in series between the harnesses and the anchor to absorb part of the
impact energy and reduce the impact force when a fall occurs.
3.7 retractable type fall arrester
A component connected in series between the harnesses and the anchor, equipped with a rope
or belt that can be extended or retracted as the personnel moves, and can trigger a locking and
braking effect due to speed changes when a fall occurs.
3.8 guided type fall arrester
A component attached to the anchor line that triggers the braking action when falling.
3.9 harnesses
A component that attaches the personal protection systems to the human body, and supports and
controls the human body, and disperses the impact force when falling.
NOTE: the harnesses are made of webbing, buckles and other metal components. There are
generally full-body harnesses, single waist harnesses and half-body harnesses.
3.10 primary strap
The webbing in the harnesses that directly bears the impact force.
3.11 secondary strap
The webbing in the harnesses that does not directly bear the impact force.
3.12 deploy distance
During the test, when the fall stops, the vertical distance from the test anchor to the lowest point
of the torso test mass in the suspended state.
3.13 fall distance
The maximum vertical distance from the starting point of the fall or the operating surface to the
lowest point of the body that wears the personal protection systems.
3.14 safety space
A three-dimensional space located below the operating surface, without objects can cause
collision damage to the falling person.
3.15 locking distance
During the test of the guided type fall arrester or retractable type fall arrester, from starting to
stopping of the movement, the movement distance of the guided type fall arrester on the anchor
line or the distance the lanyard extends from the cavity of the retractable type fall arrester.
3.16 adjusting buckle
A part used to adjust the length of the primary strap or secondary strap.
3.17 fastening buckles
A part used to tighten or loosen the primary strap.
4.2 Marking of Personal Fall Protection Systems
4.2.1 The marking of the personal fall protection systems consists of two parts: category of
operations and additional functions of the personal fall protection systems:
---Category of operations of the personal fall protection systems: regional restriction is
represented by the letter Q, work positioning is represented by the letter W, and fall
arrest is represented by the letter Z.
---Additional functions of the personal fall protection systems: anti-static function is
represented by the letter E, flame retardant function is represented by the letter F, rescue
function is represented by the letter R, and chemical resistance function is represented
by the letter C.
4.2.2 The marking of the personal fall protection systems shall be clearly indicated on the
product identification in the form of Chinese characters or letters.
EXAMPLE 1: the restraint systems indicated as “Q”; the personal fall protection systems that can
be used for work positioning, fall arrest, and have flame retardant, rescue and
chemical resistance functions are indicated as “W/Z-FRC”.
EXAMPLE 2: the restraint systems indicated as “regional restriction”; the personal fall protection
systems that can be used for work positioning, fall arrest, and have flame retardant,
rescue, and chemical resistance functions are indicated as “work positioning / fall
arrest - flame retardant and chemical resistant”.
