CHARACTERISTICS
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 recommended. The speed of the descent is about
2.10meters/second compared to 5m /second for the average elevator.
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. |
