WARNING: If the connecting element to which a snap hook (shown) or carabiner attaches is undersized or
irregular in shape, a situation could occur where the connecting element applies a force to the gate of the snap
hook or carabiner. This force may cause the gate (of either a self-locking or a non-locking snap hook) to open,
allowing the snap hook or carabiner to disengage from the connecting point.

non- compatibly
shaped element
10) CONNECTING SUB SYSTEMS
a ) Use only those connecting subsystems (self-
retracting lifeline, lanyard, rope grab and
lifeline, cable sleeves) that are suitable for your
application.
b ) See subsystems manufacturer's instructions for
more information. Some harness models have
web loop connecting points.
c ) Do not use snap hooks to connect to the web
loop. Use a self-locking carabiner to connect to
a web loop.
d ) Ensure the carabiner cannot cross-gate load
(load against the gate rather than along the
backbone of the carabiner).
11) RESCUE PLAN
a ) A rescue plan should be well documented and in
place before performing work at height.
b ) The rescue operation must be performed by
trained and competent personnel only.
c ) The rescue team expert should supervise the
rescue operation performed.
d ) It is also advised to work in pairs while working
on the site.
12) ENVIRONMENTAL HAZARDS
Environmental hazards may include the following, but
are not limited to:
UNINTENTIONAL DISENGAGEMENT (ROLL OUT)
•
Chemicals
•
Extreme Temperatures
•
Corrosive Environments
•
Gases
•
High Voltage Power Lines
•
Sharp Edges
•
Moving Machinery and Vehicles
Please contact DEWALT for use of this equipment in the
presence of any environmental hazard.
13) ANCHORAGE STRENGTH
The application type determines the anchorage strength
requirement. As per ANSI Z359.1- 2020 the necessary
anchorage strength for the following applications is
listed below:
•
Fall Arrest: As per OSHA 1926.500 and 1910.66
anchorages that are used for attachment of
Personal Fall Arrest Systems (PFAS) shall be
independent of any anchorage being used to
support or suspend platforms. They should be
capable of withstanding a minimum load of
5000 lbs. (23 kN) per user attached, or should
be designed, installed and used as part of a
complete PFAS which maintains a safety factor
of at least two. Rating of the anchorage should
always be done under the supervision of a
qualified person.
