APPLICATIONS
1.1
PURPOSE: Full Body Harnesses provide users with the means to connect to Fall Protection systems. The attachment
elements of the Full Body Harness serve as connection points for the connecting subsystem, which secures the user
to an anchorage point. Full Body Harnesses may be used for a variety of Fall Protection systems. System application
is determined by the make of your Full Body Harness and the attachment elements present on your Harness. Refer to
Section 4 for a full list of Fall Protection applications available for your Full Body Harness model.
1.2
STANDARDS: Your product conforms to the national or regional standard(s) identified on the front cover of these
instructions. If this product is resold outside the original country of destination, the re-seller must provide these
instructions in the language of the country in which the product will be used.
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.
1.4
LIMITATIONS: Always consider the following application limitations before using this equipment:
•
FREE FALL: The amount of free fall permissible per your Fall Protection system varies with your system application.
See the instruction manual of your connecting subsystem for more information on free fall requirements.
•
FALL CLEARANCE: Figure 3 illustrates the components of a Fall Arrest. There must be sufficient Fall Clearance (FC)
to arrest a fall before the user strikes the ground or other obstruction. Clearance is affected by a number of factors
including: (A) Lanyard Length, (B) Lanyard Deceleration Distance or SRL Maximum Arrest Distance, (C) Harness
Stretch and D-Ring/Connector Length and Settling (typically a Safety Factor of 1.5 ft.). Refer to the instructions
included with your Lanyard or Self-Retracting Device for specifics regarding Fall Clearance calculation.
•
SWING FALLS: Swing Falls occur when the anchorage point is not directly above the point where a fall occurs (see Figure
4). The force of striking an object in a swing fall may cause serious injury or death. Minimize swing falls by working as
directly below the anchorage point as possible. Do not permit a swing fall if injury could occur. Swing falls will significantly
increase the clearance required when a Self-Retracting Device or other variable length connecting subsystem is used.
•
EXTENDED SUSPENSION: A Full Body Harness is not intended for use in extended suspension applications. If the
user is going to be suspended for an extended length of time it is recommended that some form of seat support be
used. 3M recommends a seat board, suspension work seat, seat sling, or a boatswain chair. Contact 3M for more
information on these items.
•
ENVIRONMENTAL HAZARDS: Use of this equipment in areas with environmental hazards may require additional
precautions to prevent injury to the user or damage to the equipment. Hazards may include, but are not limited
to; heat, chemicals, corrosive environments, high voltage power lines, gases, moving machinery, and sharp edges.
Although PVC coated and zinc plated hardware exhibit excellent corrosion resistance in chemical, acidic, alkaline,
and atmospheric conditions, frequent inspections may be required. Consult with 3M if you question the use of this
equipment in hazardous environments.
;
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.
•
HARNESSES FOR HIGH TEMPERATURE ENVIRONMENTS: Harnesses with Kevlar webbing are designed for use in
high temperature environments, with limitations: Kevlar webbing begins to char at 800°F to 900°F. Kevlar webbing
can withstand limited contact exposure to temperatures up to 1,000°F. Polyester webbing loses strength at 300°F to
400°F. PVC coating on hardware has a melting point of approximately 350°F. When working with tools, materials, or
in high temperature environments, ensure that associated fall protection equipment can withstand high temperatures,
or provide protection for those items.
2.0
SYSTEM USE
2.1
RESCUE PLAN: When using this equipment and connecting subsystem(s), the employer must have a rescue plan and the
means at hand to implement and communicate that plan to users
2.2
INSPECTION FREQUENCY: The Full Body Harness shall be inspected by the user before each use and by a competent
person
other than the user at intervals of no more than one year
4
and Maintenance Log". Results of each Competent Person inspection should be recorded on copies of the "Inspection and
Maintenance Log".
2.3
COMPONENT COMPATIBILITY: 3M equipment is designed for use with 3M approved components and subsystems
only. Substitutions or replacements made with non-approved components or subsystems may jeopardize compatibility of
equipment and may affect the safety and reliability of the complete system.
1 User:
A person who performs activities at heights while protected by a personal fall protection system.
2 Authorized Person:
A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard.
3 Rescuer:
Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
4 Competent Person:
One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are
unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
5 Inspection Frequency:
competent person inspections.
Extreme working conditions (harsh environments, prolonged use, etc.) may require increasing the frequency of
