Safety Regulations
1.1
Correct Use
An MSA full body harness is a primary component of a personal fall arrest system. It may also be used for
positioning and travel restriction when the appropriate attachments are present. The harness straps are
arranged to contain the torso and distribute the forces of fall arrest to the thighs, chest, and shoulders of the
wearer.
WARNING!
DO NOT use fall protection equipment for towing or material handling. DO NOT alter this equipment or
intentionally misuse it. DO NOT use fall protection equipment for purposes other than those for which it
was designed.
If PPE is resold, it is essential that instructions for use, maintenance, and periodic examination are
provided in the language of destination.
MSA Fall Protection products may not be used while under the influence of drugs or alcohol.
Failure to follow these warnings can result in serious personal injury or death.

•
All alloy steel D-rings are zinc plated. All aluminum D-rings are anodized. All D-rings are 100% proof
tested to 3,600 lbf (16 kN). Minimum breaking strength is 5,000 lbf (22.2 kN).
•
All alloy steel buckles and adjusters are zinc plated. All aluminum buckles and adjusters are anodized.
•
Webbing is minimum 1.75 in (44 mm) nominal width. Minimum breaking strength of 5,500 LBF (24.3 kN)
when new. Check harness label for material type
•
When used as part of a personal fall arrest system, fall arresting forces must not exceed 1,800 lbf (8.0 kN).
•
Capacity is 400 lb (181 kg) including weight of the user plus clothing, tools and other user-borne objects.
ANSI Z359.11 does not recognize weight capacities over 310 lbs while applicable CSA and OSHA regu-

Usage Limitations
1.3.1
Physical Limitations
The harness is designed for one user whose weight, including clothing, tools, and other user-borne objects is
less than the capacity shown on product label. Users with muscular, skeletal, or other physical conditions that
could reduce the ability to withstand fall-arrest shock loads or prolonged suspension should consult a physician
before using. Pregnant women and minors must never use the harness. See Table 1 below for proper sizing.
