to which the specific harness model complies. (Refer to sample variable label in Appendix B.)
System Compatibility
Miller full-body harnesses and body belts are designed for use with Honeywell-approved components only. Substitution or
replacement with non-approved component combinations or subsystems or both may affect or interfere with the safe function
of each other and endanger the compatibility within the system. This incompatibility may affect the reliability and safety of the
total system.
WARNING
Always refer to the regulations and standards regarding personal fall arrest system component requirements and the instruc
-
tions provided with each component being used as part of the personal fall arrest system.
Limits of Use
Fall arrest connecting devices shall be attached to the dorsal attachment element (back D-ring) of the full-body harness unless the
application allows for the use of an alternate attachment. (Refer to 5.1.)
Anchorage Requirements
Anchorage must be capable of supporting 5,000 lbs (22.2 kN) per worker or meet OSHA 1926.502 requirements for a safety factor
of two. ANSI anchorage requirements are as follows:
• For fall arrest systems, anchorages must withstand a static load of 5,000 lbs (22.2 kN) for non-certified anchorages or two
times the maximum arresting force for certified anchorages.
• For positioning systems, anchorages must withstand a static load of 3,000 lbs (13.3 kN) for non-certified anchorages or two
times the foreseeable force for certified anchorages.
• For travel restraint, anchorages must withstand a static load of 1,000 lbs (4.5 kN) for non-certified anchorages or two times the
foreseeable force for certified anchorages.
• When more than one personal fall arrest system is attached to an anchorage, the above anchorage strengths must be
multiplied by the number of personal fall arrest systems attached to the anchorage.
TABLE 1: Harness Capacity Range*
For harnesses marked compliant with...
ANSI Z359.11 and/or ANSI A10.32 (and OSHA) 130-310 lbs (59-140kg)
CSA Z259.10 (and OSHA) Max. 420 lbs (190.5kg)**
OSHA ONLY Max. 400 lbs (181.4kg)
ANSI, CSA and OSHA Max. 420 lbs (190.5kg)***
*Includes body weight, clothing and tools.
**CSA Z259.10 does not specify a capacity range for harnesses; therefore, the manufacturer may establish the maximum capacity
based on testing in accordance with CSA requirements and their internal test program.
***Honeywell, as the manufacturer, rates the harnesses to a maximum 420 lbs (190.5 kg); however, it is ultimately the responsibility
of the user and the user’s employer to determine if they elect to comply with the ANSI standards which limit capacity range to 130-
310 lbs (59-140 kg).
Note: For compliance with OSHA 1926.502(d)(16) -- If the system is used by an employee having a combined tool and body
weight between 310 lbs. (140.6 kg) and 420 lbs. (190.5 kg), then the employer must appropriately modify the criteria and protocols
to provide proper protection for such heavier weights, or the system will not be deemed to be in compliance with the requirements
of OSHA 1926.502(d)(16).

3 WEARING A FULLBODY HARNESS
3.1 Proper Harness Fit
Correct fit of a full-body harness is essential to proper performance. Users must be trained to select the size and maintain the fit
of their full-body harness. Users must follow these instructions for proper fit and sizing, paying particular attention to ensure that
buckles are connected and aligned correctly, leg straps and shoulder straps are kept snug at all times, chest straps are located in
the middle chest area, and leg straps are positioned and snug to avoid contact with the genitalia should a fall occur. It is extremely
important to maintain a proper fitting harness through the entire duration of a work shift
3.2 Donning a Harness
1. Hold harness by back D-ring. Shake harness to allow all straps to fall in place.
2. If chest, waist and/or leg straps are connected, release straps by unbuckling.
3. Slip straps over shoulders so D-ring is located in middle of back between shoulder blades.
4. Pull leg strap between legs and connect to corresponding end. Repeat with second leg strap. Tighten
leg straps so that they are snug, but not so snug as to obstruct normal blood circulation in the legs.
Connect waist strap/belt, if present. Waist strap/belt should be snug but not binding.
5. Connect chest strap and position in mid-chest area 6” (152mm) to 8” (203mm) below the
trachea but not below the sternum. If adjustable, tighten chest strap to keep shoulder straps taut.
Note: If the chest strap is positioned too high, it may move upward during a fall arrest causing the user to risk strangulation.
If the chest strap is positioned too low, or not connected at all, the user will be at risk of falling out of the harness during a fall.
6. Tighten shoulder straps until snug.
7. After all webbing straps have been buckled, readjust harness fit as needed so that harness is snug but allows full range of
movement. Secure excess strap in elastic loop keepers.
8. Verify correct harness fit using the following checklist:
• All buckles are properly connected.
• Webbing straps are not twisted and are snug with excess webbing secured in elastic loop keepers.
• Back D-ring is located in middle of back between shoulder blades.
