APPLICATIONS
1.1
PURPOSE: Full Body Harnesses are to be used as components in Personal Fall Protection System designed to prevent a
fall or safely arrest a fall. Full Body Harnesses are used in the following applications:
Application
Personal Fall Arrest
Controlled Descent
Rescue
Ladder Climbing
Work Positioning
Restraint
!
CAUTION: Certain application and work conditions require the use of Full Body Harnesses with specifi c attributes:
•
Full body harnesses with Kevlar® web should be used when working with tools, materials, or environments of high temperature
(foundries, chemical manufacturing, steel fabrication, emergency rescue services, fi re services, welders, oil industry, nuclear
industry, explosives).
•
Harnesses with PVC coated hardware should be used when working in explosive or electrically conductive environments, or where
surfaces must be protected from the hardware.
•
Harnesses with high visibility webbing should be used when increased visibility of the user is required
1.2
STANDARDS: Harnesses included in this manual conform to the standard(s) identifi ed on the front cover of this
instruction.
1.3
TRAINING: It is the responsibility of the user and the purchaser of this equipment to assure that they are familiar with
these instructions, trained in the correct care and use of, and are aware of the operating characteristics, application limits,
and the consequences of improper use of this equipment.
!
CAUTION:
Training must be conducted without exposing the user to a fall hazard. Training should be repeated on
a periodic basis.
1.4
LIMITATIONS: Always consider the following application limitations before using this equipment:
•
CAPACITY: The Full Body Harness is designed for use by persons with a maximum combined weight (clothing, tools,
etc.) of 352 lbs (160 kg). Make sure all of the components in your system are rated to a capacity appropriate to your
application.
NOTE:
352lbs (160 kg) is the maximum capacity allowed by CSA Z259.10. Capital safety harnesses are
factory tested to a maximum OSHA capacity of 420 lbs (191 kg).
•
FREE FALL: Personal fall arrest systems used with this equipment must be rigged to limit the free fall to 6 feet (1.8
m). 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 m) or less. Rescue
systems must be rigged so that no vertical free fall is possible. See subsystem manufacturer's instructions for more
information.
CSA Class
Description
Class A
The full body harness is used as a component of a personal fall arrest system.
Personal fall arrest systems typically include a full body harness and a connecting
subsystem (energy absorbing lanyard). Maximum arresting force must not exceed
1,800 lbs (8 kN). For fall arrest applications connect the fall arrest subsystem
(example: lanyard, SRL, energy absorber, etc.) to the D-Ring or attachment
element on your back, between your shoulder blades.
Class D
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).
Class E
The full body harness is used as a component of a rescue system. Rescue systems
are confi gured depending on the type of rescue. For limited access (confi ned space)
applications, harnesses equipped with D-Rings on the shoulders may be used for
entry and egress into confi ned spaces where worker profi le is an issue.
Class L
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 fi xed
ladder climbing systems. These are defi ned in CSA Z259.2.5 in Canada and ANSI
A14.3 in the United States.
Class P
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.
None
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.
