2.0 EQUIPMENT LIMITATIONS & REQUIREMENTS
Always consider the following limitations and requirements when installing or using this equipment.
2.1 CAPACITY:
AC4000 AND AC4001 WORK RESTRAINT USE: The Viper™ LT Rope and Rope Grab AC4000 and AC4001
assembly is designed for use by one person with a combined weight (person, clothing, tools, etc.) up to 100
kg (220 lbs). At no time shall more than one person connect to the Viper™ LT Rope and Rope Grab for Fall
Restraint applications.
AC4002 VERTICAL FALL ARREST USE - 140KG (308 LBS): The Viper™ LT Rope and Rope Grab AC4002
assembly is designed for use by one person with a combined weight (person, clothing, tools, etc.) up to 140
kg (308 lbs) for vertical use
AC4002 ROOFTOP FALL ARREST USE - 100KG (220 LBS): For rooftop fall arrest use the capacity of the
AC4002 product is 100 kg (220 lbs). At no time shall more than one person connect to the Viper™ LT Rope
and Rope Grab.
2.2 ROPE TYPE: The Viper™ LT Rope Grab must be used with the supplied 12.5 mm (
Rope.
2.3 VERTICAL FALL ARREST USE: Users can attach to the sternal attachment point of harness and ascend a
vertical structure using a 12.5mm rope supplied by capital Safety. The necessary minimum fall clearance
below the feet of the user is:
AC4000: greater than 2.0 m
AC4001: greater than 2.4 m
AC4002: greater than 2.7 m
This takes into account the arrest distance and elongation of the anchor line.
2.4 ROOFTOP WORK RESTRAINT USE: The user should minimize the amount of slack in the Rope near a
potential fall hazard. To minimize a risk of a fall do not adjust the Rope Grab while moving towards a fall
hazard as this may affect the ability of the device to prevent a fall. Also, if the risk assessment carried out
before the start of work shows that a fall over an edge is possible, then appropriate precautions must be
taken before the start of work to eliminate the risk of falling over the edge (e.g. using product AC4002),
or an edge protection barrier should be installed before the start of work, or the user should contact the
manufacturer for guidance. The risk assessment should also consider the increased risk of slipping and
falling where the user is working on an area of the roof that is inclined, particularly if wet, frozen or the
angle is greater than 15 degrees from the horizontal. If there is any doubt, the system should not be used in
these circumstances.
2.5 ROOFTOP FLAT/SLOPED FALL ARREST USE: For this application AC4002 must be used as this product
has been designed and tested for falls over a 0.5mm radius edge. Where the sharpness of an edge can not
be defi ned the rope lifeline must be protected from contact with sharp or abrasive edges and surfaces. The
Rope Grab should be connected to the body support using the supplied locking carabiner. The Rope Grab
locking operation must not be hindered by interference with the roof or objects on the roof surface.
Ensure suffi cient clearance exists in your fall path to prevent striking an object during a fall if working close
to the edge. The necessary minimum fall clearance below the feet of the user is 3.8m.
2.6 SWING FALLS: Swing falls occur when the
anchorage point is not directly above the point
where the fall occurs (see Figure 4). The force
of striking an object can cause serious injury or
death.
If the user wishes to access the edge of the
roof (limited access zone) then a leading edge
restraint should be used to avoid a swing fall
(see Figure 3).
2.7 ENVIRONMENTAL HAZARDS: Use of this equipment in areas with environmental hazards may require
additional precautions to prevent injury to the user or damage to the equipment. Hazards may include,
but are not limited to; heat, chemicals, corrosive environments, high voltage power lines, gases, moving
machinery, and sharp edges.
WARNING: When working with tools, materials, or in high temperature environments, ensure that
associated fall protection equipment can withstand high temperatures, or provide protection for those
items.
