Escaping a fire is a serious matter:
knowing what to do during a fire can save life. It is important to know the way
you can use and show them to everyone in the family, such as stairs and fire
escapes, but not lifts. From the lower floors of building, escape through
windows is possible. Learn the best way of leaving by window with the least
chance of serious injury.
The second floor window is usually not very
high from the ground. A person of average height, hanging by the fingertips
will have a drop of about 6 feet to the ground. It is about the height of an
average man. Of course, it is safer to jump a short way than to stay in a
burning building.
Windows are also very useful when you are
waiting for help. Be sure to keep the door closed before opening the window.
Otherwise, smoke and fire may be drawn into the room. Keep your head low at the
window to be sure you get enough fresh air rather than smoke that may have
leaked into the room.
On a second or third floor, the best
windows for escape are those which open onto a roof. From the roof a person can
drop to the ground more safely. Dropping onto the cement might end in injury.
Bushes and grass can help to break a fall.
