1.1 Correct Use
The Rope Grab subsystem is a component of a personal fall arrest system. The components of the
Rope Grab subsystem are a lanyard with an integrated energy (shock) absorber, fall arrester (rope grab)
and lifeline. Other components required to make up complete systems are MSA full body harnesses only
and a suitable anchorage and anchorage connector, as determined by a competent person. The length of
the lifeline must extend either: 1) from the anchorage to the ground, or, 2) from the anchorage, a suitable
distance beyond the level of the lowest working surface.
See instruction labels on the product for capacity of that system. All systems are designed for a single
person, with only one person on the lifeline at any time.
The Rope Grab subsystem is intended for use by trained and qualified personnel.
It is imperative that this manual be read and observed when using the product. In particular, the safety
instructions, as well as the information for the use and operation of the product, must be carefully read and
observed. Furthermore, the national regulations applicable in the user's country must be taken into account
for a safe use.
Alternative use, or use outside this specification will be considered as non-compliance. This also applies
especially to unauthorized alterations to the product and to commissioning work that has not been carried
out by MSA or authorized persons.

1.3 Usage Limitations
1.3.1 Physical Limitations
Persons with muscular, skeletal, or other physical disorders should consult a physician before using the
Rope Grab subsystem. Pregnant women and minors must never use the Rope Grab subsystem. Increasing
age and lowered physical fitness may reduce a person’s ability to withstand shock loads during fall arrest
or prolonged suspension. Consult a physician if there is any question about physical ability to safely use this
product to arrest a fall or suspend.
1.3.2 Hazards
Chemical hazards, heat and corrosion may cause damage. More frequent inspections are required. Do not
use in environments with temperatures greater than 185° F (85° C) as this will cause the lifeline to melt. Use
caution when working near electrical hazards, moving machinery, sharp edges and abrasive surfaces.
WARNING
The rope grab and vertical lifeline system must not be used when the user is positioned on an
unstable surface, fine grain material, or particulate solids such as sand or coal. Misuse can result in
serious injury or death.
