Risk Safety Systems - Single Entry Escape Chute applications for Emergency Services
Fire & Rescue & Emergency Services:
Escape Chutes can be fitted to Fire Department Aerial Ladders and Snorkel Platforms,
this will increase the rate at which evacuees can be evacuated from a high rise building,
thus reducing the risk of exposure of the fireman. The movable/portable chute has
become standard rescue equipment used by fire bridges worldwide for high rise rescue
operations. With additional equipment, the portable platform can also be mounted
on the parapet of the balcony and window.
The chute is constructed of 3 layers, the outer layer is fire resistant-protects
the chute against flames, the middle layer provides a speed restraining effect, and
the inner layer supports the whole weight of the chute. Protection,the evacuees
are protected once inside the chute from flames, heat, and smoke.
RSS ESCAPE CHUTE Technical Specifications for the Mobile/Portable Rescue Chute.
Mobile/Portable Rescue Chutes have become standard rescue equipment for fire aerial
ladder trucks such as Bronto Skylift, Simon Snorkel, Cella, Iveco Magirus, Metz and
Rosenbauer and are used by fire brigades worldwide for high rise rescue operations.
The Mobile Unit provides a dual function in one, portable and suitable for the rescue
of people trapped in tall buildings. The universal standard foldable platform is
portable and adaptable for use with mobile rescue units, such as the fire brigades’
aerial ladder trucks. The foldable platform can either be ready mounted on the bucket
or in a cassette, which is ready for use as required. With additional equipment,
this platform can also be used from the window or balcony of a structure.
The chute main body is made up of several segments of 3 layers chute. The start piece
of the first segment, usually of 61m or 8 long with fire snap hooks on one end. The
other segment of chute with fire snap hooks on both ends usually corresponds to the
height of a regular floor. The starting piece and the other segments are easily connected
with fire snap hooks for extending the chutes height to meet the desired chute length.
Customers can specify the length for the start piece or each segment to meet their
individual rescue needs.
The quick deployment of the mobile rescue unit provides people who are trapped buildings
a safer means of rapid escape from the bucket to ground and reduces the risk of exposure
for the firefighters. This approach eliminates the time involved in lowering and
raising the aerial-ladder platform, hence reduces the speed of rescuing victims from
tall buildings by almost ten times in comparison to using the conventional method.
Should the surroundings of the building not be accessible by the fire aerial truck,
the portability of the unit allows the rescue personnel to carry the unit to each
desired floor. This additional equipment allows the rescue chute to be positioned
at the parapet of the balcony or window. However, the rescuer must ensure that the
wall of the balcony and window, ceiling and floor are structurally safe for the unit
to be deployed. The maximum safety load is 200 kg or 50 meter in height.
Universal foldable platform – 100% aluminum (frame and cast), foldable, portable,
attachable to buckets of most fire trucks. Aluminum cast Alsi nr 6. Steel ring.
Portable carrier bags are provided for the storage of each chute section.
The chute main body material is gray in color, constructed of three layers chute.
This 3-way protection protects the evacuees once inside the chute from flame, heat,
and smoke during the rescue operation.
Outer Chute – The protection layer with a heat resistance of 600 degrees and a melting
point of 800 degrees. Temperature limits for continuous use 550-600 degrees Celsius.
This material provides a shield from flame, and provides protection to the two underlying
Middle Chute– The braking layer Modacryl and Elastomer (lycra) at sofetning point
of 165 degree Celsius. This elastic material, covering inner chute that enables the
user to control his/her speed of descent. The important properties of these materials
are its modulus of elasticity (260%) and its withstanding temperatures of 165 degrees
Inner Chute – The friction layer Interlayer Para Aramid, warp and vet Viyl Chloride
fibres. Strength ISO 5081 (N) 3482 stripes 50mm and its tensile strength ISO (N)
10mm stripes support the chute. No softening point, decomposing temperature at about
500 degree Celsius. Evacuees slide down the chute through this inner layer, which
bears the tensile stress, and has extremely low friction to minimize friction burns
Each fire snap hook is constructed from stainless steel, these can be adjusted to
extend or shorten the chute length. Each end of lengthening joint contains one segment
of chute consisting of 12 sets of fire snap hooks for easy connection to the next
segment of chute.
Descent and Safety:
The system works on the principle of gravity, using the stress and friction of the
body as it slides through the chute. Usability for all people, regardless of body
size, shape and weight, injured on a stretcher or unconscious people can use the
chute. Once inside the chute the evacuee will arrive at ground level quickly and
For conscious evacuees, slide down the chute and push out your elbows or knees. For
a more rapid descent, the users keep their body as straight as possible. No other
method of evacuation allows for such flexibility in control of descent speed: average
speed for evacuee with right behavior is about 2.5 m per second, which may vary from
0 – 5 m per second. It would take approximately 35 – 40 seconds to descend a chute
of up to 50 meters and capable of conveying up to 30 persons per minute from any
storey to safety.
For safety reasons, the SOP requires a helper at ground level to control a fast descend
and guide the user out of the chute. By twisting and slowly untwisting the chute
you can control the speed of a descending person. This method enables the injured,
unconscious, disabled and small children to be evacuated safely.
Storage of Chute:
The chutes are folded inside its protective container and portable bag(s), providing
year round weather protection, these chutes are then ready for use at any time. After
use, the chute can be re-stored in its container and portable bag(s). Whilst not
in use, the chute is protected from dampness, salt in the air and chemical agents,
by a thin 25/100 PVC layer, this must be checked at least twice a year.
