Deployment Procedures RAPID
& SAFE EVACUATION OF BUILDINGS:
The essential element
of any Disaster Management regime is rapid and safe evacuation of buildings under
threat from Fire, Earthquake and acts of terror. Where the
premises contain highly combustible substances, or toxic chemicals, the urgency
for quick evacuation is even more important. Fire Lifts,
(if available), and the Fire Stairs are no solution, especially in high rise buildings. The
HERMES GROUP introduces to India the vertical FIRE ESCAPE CHUTE system that is
already popular use in Europe, USA and many other countries. This offers and independent
external escape option. Fire Escape Chutes operate on the principle of CONTROLLED
SLIDING down a chute made of Fire Retardant material. The basic routine for use
is similar to the inclined inflatable chute used for air craft evacuation on water. Of
the many systems in use, the Hermes Group selected and has an exclusive distribution
agency agreement with AXEL THOMS for their patented SPIRAL descent chute, which
is acknowledged as the safest and the most popular. It is preferred by discerning
users and has been in the market for over 27 years. Designed
and built to strict quality standards, the system assures the user of a safe descent
from any height at a descent rate of about 2 metres per second. At the lower end,
suspended about 400mm above the ground for easy exit, is a thick foam cushioned
seat composed entirely of fabric. Systems already in operation
are as long as 114 metres or equivalent to about 38 stories. These
systems are folded into small packages stored in a container fitted at a window
on the outside perimeter of the building. Alternatively, these may be installed
on terraces, or balconies. Thus there is no change in external appearance of the
buildings where these are installed. When the Escape Chute
is to be deployed, the user opens the box and can deploy the chute within 40 seconds
enabling evacuation to commence immediately the alarm is raised. Entry
is by one person at a time, and one can follow the other as soon as space at the
top is available, without waiting for the previous person to exit at the bottom. Where
tall structures have rescue platforms, such chutes can be installed on each such
platform for sending evacuees from one platform the next till they reach the ground. The
Fire Escape Chute is more efficient and reliable compared to a spiral staircase,
especially for infants and small children. In many cities
and countries, Fire Escape Chutes have become compulsory or the preferred escape
system. Since chutes is deployed OUTSIDE the building, they are provided with
holding handles at ground level, and also lashing ropes, to anchor the chute if
required, to resist oscillation during high wind conditions. In
addition to installation in residential & commercial buildings, hospitals, hotels,
restaurants, shopping malls, government buildings, games stadiums, other possible
applications include: Mounting on Fire Escape Ladder vehicles
of the Fire Department for safe and rapid descent as compared to the slow and
unsafe descent using the ladders; Mounting on tall machinery
such as Tower Cranes, Open Mine Excavators, and the like, for quick descent in
case of fire; Mounting on maritime Light House Towers, where
there is no help possible in the event of fire; Mounting on Control Towers at
airports, naval vessels, especially carriers, at power stations, tall factory
buildings such as cement kilns and silos, oil rigs and oil refineries, oil tanks,
gas tanks, and the like; Evacuating ships' passengers onto life boats or rafts
instead of jumping over side. The potential application
can be expanded according to the imagination of the user and the consulting architect. The
initial cost of individual Fire Escape Chutes should not distract potential users.
In the present economic scenario, it is important to protect lives and skills.
The breadwinner of the family is irreplaceable, and the ski lied staff member
at any enterprise is not easily replaced. It is in the interest of employers and
local bodies to encourage and fund systems that ensure safe evacuation wherever
there is an emergency. The system, once installed, is guaranteed
for a life of 15 years under careful annual maintenance, and can be used up to
4000es should the need arise. The capital cost is like an insurance premium for
the preservation of skilled manpower. |
