3.0 OPERATION AND USE
WARNING:
Do not alter or intentionally misuse this equipment.
Consult DBI-SALA when using this equipment in combination with
components or subsystems other than those described in this manual.
Some subsystem and component combinations may interfere with the
operation of this equipment. Use caution when using this equipment
around moving machinery, electrical hazards, chemical hazards, and
sharp edges.
WARNING:
Consult your doctor if there is reason to doubt your
fi
tness to
safely absorb the shock from a fall arrest. Age and
fi
tness seriously affect
a worker’s ability to withstand falls. Pregnant women or minors must not
use a DBI-SALA winch, unless for unavoidable emergency use situations.
3.1 BEFORE EACH USE:
Inspect this equipment carefully to ensure
it is in good working condition. Check for worn or damaged parts.
Ensure all parts are present and secure. Check operation of the
winch; ensure that it will lift, lower, and hold the load under
normal operation. Check the winch and entire system for damage
and corrosion. See section 5.0 for further inspection details. Do not
use if inspection reveals an unsafe condition.
3.2 PLANNING:
Plan your system and how it will function before starting
your work. Consider all factors that affect your safety during use.
Some important points to consider when planning your system are:
A. HAZARD EVALUATION:
Evaluate job site hazards prior to
starting work. Consult applicable OSHA and industry standards
for guidelines and regulatory requirements on issues such as
confined space entry, personal fall arrest systems (PFAS), and
single point adjustable suspended scaffolds.
B. WORK SITE GEOMETRY:
The installation and use of
the support structure (tripod, davit arm and base) must
be consistent with the geometric requirements stated in
the associated manufacturer’s instruction manuals. When
suspending working lines from the support structure, check for
obstructions or sharp edges in the work path. Avoid working
where the user may swing and hit an object, or where lines
may cross or tangle with that of another worker.
C. SECONDARY OR BACK-UP FALL ARREST SYSTEM:
When
using the Digital Winch as a support for work positioning or
for personnel riding, a secondary or back-up fall arrest system
is required. See OSHA 29 CFR 1910.28 and 1926.451. The
DBI-SALA tripod and davit arm have provisions for connection
of a secondary or back-up PFAS. See sections 3.3 and 3.5 (A).
D. RESCUE:
A means of dealing with an accident or emergency
must be planned in advance. Response time can play an
important role in the survival of an injured worker. Users of
this equipment must be trained in emergency procedures.
