HARNESS CERTIFICATION AND USE 

Rescue and work harnesses from CMC Rescue are 

 

 

 

 

 

 

 

designed to comfortably support the wearer, creating a safe 
work platform. Because our harnesses are used when working 
at heights, they are also built with the strength to catch a fall. 
NFPA 1983 provides specifications for rescue harnesses. All 
front and back D-ring connection points are dynamically and 
statically tested to this standard. The side D-rings are tested 
as pairs in the manner of use. 

USER INFORMATION 

User Information shall be provided to the user of the      

product. NFPA Standard 1983 recommends separating the 
User Information from the equipment and retaining the 

 

 

 

 

 

 

 

information in a permanent record. The standard also 

 

 

 

 

 

 

 

 

recommends making a copy of the User Information to keep 
with the equipment and that the information should be referred 
to before and after each use. 

Additional information regarding auxiliary equipment can be 

found in NFPA 1500, 

Standard  on  Fire  Department             

Occupational Safety and Health Programs

, and NFPA 1983, 

Standard on Life Safety Rope and Equipment for Emergency 
Services. 

INSPECTION 

Inspect the equipment according to your department's policy 

for inspecting life safety equipment. Inspect the equipment 
prior to entry into service, after each use, and at least once 
every 12 months. The equipment should be thoroughly 

 

 

 

 

 

 

inspected by an inspector that meets your department's 

 

 

 

 

training standard for inspection of life safety equipment. Keep 
a record of the date, person performing the inspection and 
results, as well as the date of first use, name of users and any 
other pertinent information necessary to keep accurate track of 
the equipment’s usage history in the equipment log or on a tag 
that attaches to the equipment. Each user should be trained in 
equipment inspection and should inspect the equipment before 
each use. 

When inspecting the equipment, check the webbing and 

rope for cuts, worn or frayed areas, broken fibers, soft or hard 
spots, discoloration, or melted fibers. Check the stitching for 
pulled threads, abrasion, or breaks. Check the hardware for 
damage, sharp edges, and improper operation. If any of the 
above is noted, or if the equipment has been subjected to 
shock loads, fall loads, or abuse other than normal use,      
remove the equipment from service and destroy it. If there is 
any doubt about the serviceability of the equipment, remove 
the equipment from service and destroy it. 

The service life of equipment depends greatly on the type of 

use and the environment of use. Because these factors vary 
greatly, a precise service life of the equipment cannot be    
provided. 

PUTTING ON YOUR HARNESS 

1)  Loosen the adjusting buckle on each side of the waist belt 

to make the waist larger (one or both waist quick-connect 
buckles may be disconnected to facilitate donning the   
harness). 

2)  Holding the harness by the right shoulder strap, unhook the 

shoulder and thigh quick-connect buckles. With the 

 

 

 

 

shoulder strap in the right hand, step through the waist 
belt.*  

3)  Pull the waist belt up around your waist while sliding the 

shoulder strap over your right shoulder (re-connect the 
waist buckles if necessary). 

4)  Tighten both waist straps until the waist is snug, and the 

front D-ring is centered. Fold the ends of the waist straps 
under the Web-Keepers™ and secure them tightly. 

5)  Connect the shoulder strap quick-connect buckle.  

6)  Adjust the shoulder straps by sliding the webbing through 

the adjusting buckle until the straps are snug.  

7)  Connect the thigh quick-connect buckles and adjust until 

snug. 

*An optional donning technique is to leave the shoulder strap 
connected and disconnect either the left or right waist belt 
quick-connect buckle. Step through the space between the 
connected side of the waist belt and the leg loop while placing 
the shoulder straps over your head.  

A suspension test should be carried out in a safe place prior 

to putting the harness in service. A suspension test will verify 
that the harness is the correct size, has sufficient adjustment 
and is of an acceptable comfort level for the intended use. 

WARNING: Make sure the straps are snug. This 

 

 

 

 

 

 

 

increases the comfort when sitting in the harness and 
helps prevent the quick-connect buckles from 

 

 

 

 

 

 

 

disconnecting. When wearing the harness, double-check 
the buckles, adjusters, and fit of the harness immediately 
prior to relying on it for support. 

ATTACHMENT POINTS 

• 

The dorsal D-ring is the attachment point accommodates 
operations where a dorsal attachment point is warranted 

• 

The front waist D-ring is the primary rescue/work positioning 
attachment point. It allows the user to be in a sitting position 
which provides the most comfort and freedom of movement. 

• 

The front sternum D-ring holds the user in a more upright 
position which may provide easier access during a vertical 
entry or exit. 

• 

The side D-rings are for work positioning and must always 
be used in pairs. 

To prevent roll out when using carabiners to attach to 

an attachment point, use only locking models. If using 
manual locking carabiners, verify that they are locked  
before use. CMC/Roco Harnesses are not intended for 
rock climbing. Leadclimbing ropes should not be tied into 
the D-ring or connected into it with a carabiner. 

CARRYING, MAINTENANCE & STORAGE 

During use, carrying and storage keep the equipment away 

from acids, alkalis, exhaust emissions, rust and strong 

 

 

 

chemicals. Do not expose the equipment to flame or high   
temperatures. Carry the equipment where it will be protected 
as the equipment could melt or burn and fail if exposed to 
flame or high temperatures. 

If the equipment becomes soiled, it can be washed in cold 

water with a mild detergent that is safe for use with nylon and 
polyester. Dry out of direct sunlight. Do not dry in an automatic 
dryer. Store in a cool, dry location. Do not store where the 
equipment may be exposed to moist air, particularly where 
dissimilar metals are stored together. 

REPAIR 

All repair work shall be performed by the manufacturer. All 

other work or modifications void the warranty and releases 
CMC from all liability and responsibility as the manufacturer.
