B. WORK POSITIONING: The full body harness is used as a component of a work positioning system
to support the user at a work position. Work positioning systems typically include a full body harness,
positioning lanyard, and a back-up personal fall arrest system. For work positioning applications, connect
the work positioning subsystem (example: lanyard, Y-lanyard, etc.) to the lower (hip level) side or belt
mounted work positioning attachment anchorage elements (D-rings). Never use these connection points
for fall arrest.
C. LADDER CLIMBING: The full body harness is used as a component of a climbing system to prevent the
user from falling when climbing a ladder or other climbing structure. Climbing systems typically include
a full body harness, vertical cable or rail attached to the structure, and climbing sleeve.For ladder
climbing applications, harnesses equipped with a frontal D-ring in the sternal location may be used for
fall arrest on xed ladder climbing systems. These are dened in Z259.2.1 in Canada and ANSI A14.3 in
the United States.
D. RESCUE: The full body harness is used as a component of a rescue system. Rescue systems are
configured depending on the type of rescue. For limited access (conned space) applications, harnesses
equipped with D-rings on the shoulders may be used for entry and egress into conned spaces where
worker prole is an issue.
E. CONTROLLED DESCENT: For controlled descent applications, harnesses equipped with a single sternal
level D-ring, one or two frontal mounted D-rings, or a pair of connectors originating below the waist
(such as a seat sling) may be used for connection to a descender or evacuation system (reference in
Z259.10 in Canada).
F. RESTRAINT: The full body harness is used as a component of a restraint system to prevent the user
from reaching a fall hazard. Restraint systems typically include a full body harness and a lanyard or
restraint line.
1.2 LIMITATIONS: Consider the following application limitations before using this equipment:
• CAPACITY: These full body harnesses are designed for use by persons with a combined weight
(clothing, tools, etc.) for ANSI Z359.1--310 lbs (141 kg), CSA Z259.10--352 lbs (160 kg). Make sure all
of the components in your system are rated to a capacity appropriate to your application
• FREE FALL: Personal fall arrest systems used with this equipment must be rigged to limit the free fall to
6 feet (1.8 M) (ANSI Z359.1). Restraint systems must be rigged so that no vertical free fall is possible.
Work positioning systems must be rigged so that free fall is limited to 2 feet (.6 m) or less. Personnel
riding systems must be rigged so that no vertical free fall is possible. Climbing systems must be rigged
so that free fall is limited to 18 in. (.46 cm) or less. Rescue systems must be rigged so that no vertical
free fall is possible. See subsystem manufacturer’s instructions for more information.
