User Instruction Manual Supplement - English
3.0 Requirements, Warnings
and Limitations
Users must read, understand and follow all requirements, warnings and limitations
provided in the Miller Harnesses and Body Belts instruction manual (I119) as well as this
supplement.
Fall protection connecting devices should be attached to the back D-ring or back D-ring
extension. A front D-ring may be used for fall arrest only in applications where the personal fall arrest system limits the maximum free fall distance to 2 ft. (0.6m) and limits the
maximum arrest force to 900 lbs. (4kN).
The back waist level D-ring is designed for restraint applications only.
A personal fall arrest system must be in place and connected at all times when either the
bosun chair or seat sling are in use.
The seat sling is designed for short, temporary support and assistance while climbing.
Use bosun chair and seat sling D-rings only for positioning during suspended work or
assisted climbing.
Always ensure that there is adequate fall clearance for the application. Remember that
the use of the D-ring extension will add 18 in. (458mm) to the fall clearance required.

are securely and properly connected.

Cam Buckle Adjustment
1) Grasp the loose end of web-
bing strap and pull to tighten.
Tuck excess webbing into elastic
keepers.
2) To loosen, press cam buckle
tab outward to release grip and
pull webbing strap out through
buckle.
Fall Arrest (Figs. 1, 2, 3 & 4)
A compatible connecting device and anchorage connector/anchorage must always be used in
conjunction with the harness to complete the personal fall arrest system and protect the worker
from a fall while working at heights. The bosun chair and seat sling are not designed to arrest a
fall.
The connecting device must be connected to the back D-ring or back D-ring extension on the
harness. When the D-ring extension is used, always remember to add 18 in. (458mm) to the fall
clearance calculation.
A two-legged shock-absorbing lanyard or dual self-retracting lifeline system is recommended for
climbing applications. Alternatively, a fall arrester attached to a vertical climbing system may be
connected to the front D-ring on the harness so long as the personal fall arrest system limits the
maximum free fall distance to 2 ft. (0.6m) and limits the maximum arrest force to 900 lbs. (4.0kN).
For non-climbing applications, a single shock-absorbing lanyard or self-retracting lifeline is
sufcient.
Suspension (Figs. 1 & 2)
For suspension work, connect the bosun chair D-rings to an approved, compatible suspension
system. A personal fall arrest system must be used in conjunction with the suspension system.
Climb-Assist (Fig. 3)
Connect the seat sling D-rings to an approved, compatible climb-assist system. The sling is
designed for temporary support during extended climbing applications. Do not use for suspension
work. A personal fall arrest system must be used in conjunction with the climb-assist system.
Restraint (Fig. 4)
The waist-level back D-ring is designed for restraint applications only. Simply attach a lanyard
between the restraint D-ring and the anchorage connector/anchorage. A personal fall arrest
system must be used in conjunction with the restraint system.
Note: Always read and follow the instructions provided with all system components
used in conjunction with the AirCore Oil & Gas Harness.
