OPERATION
At the time of fire, remove the
cabinet that contains the escape chute, open the window, throw
down the guide rope fixed at the bottom of the chute to
the ground and let the chute body hang down gradually.
When the chute body has been
lowered and the chute body hangs down completely,
push the metal frame upward and extend the frame out of the
window.
The operator on the ground
first pull the guide rope that has been thrown down, then
pulls the chute body toward the anchor that is previously installed
on the ground, connect the hooks from chute on the anchor and pull
the pulley to full extend and stabilize the chute body.
The reason why the chute need to
hook with anchor is to provide firm support of the chute to provide smooth descent
for patient on stretcher or number of evacuees descend in
succession, holding the bottom of the chute by hand is not
recommanded.
DESCENT & SAFETY
This type of escape chute required proper anchorage,
otherwise smooth descent is not guaranteed unless the bottom of the chute
is held firmly or hooked on the anchor installed on the ground.
Therefore, always check the connection between the anchor and hooks
of the chute before start evacuation.
The escape chute may be regarded
as a slide made of cloth. Descent in succession one after
another is possible. It may be a good idea if the person
extends his legs outward to regulate the speed of descent.
The chute body is of double-construction
from up to down. Even if the chute cloth should tear, the
nylon taffeta, the second layer of cloth which is very strong,
prevents accidental fall of the person through the torn part.
The chute has a protecting cushion at the bottom to avoid
shock at the time of landing on the ground.
