How
they are used?
An
extinguisher is an apparatus under designed pressure to expeler its
load in such a way that it is possible with her successfully to attack
a center of fire. This it is a concept of extreme importance: The
extinguishers only serve to choke fire principles. They do not serve
to extinguish fires, because in that case the action of professionals
in the subject is required (the firemen). But they are fundamental so
that a fire does not become a fire.
The
size of the fire, the intensity of their flames, the wind direction to
locate to us and to be able to attack it is elements fundamental to
consider for the success of our task. Once determined quickly the
previous elements one is due to come to choose the suitable
extinguisher.
It
is important to know that the instructions of use of the extinguishers
are obligatorily in the front of all the equipment. The loss of some
seconds in its reading surely will result in a greater efficiency of
those people nonexperienced in the subject.
It
is fundamental NOT TO USE an equipment with water if in the zone of
the fire the electrical current has not been cut previously. Also it
is very important to remember that no longer EQUIPMENT EXISTS THAT
MUST BE INVESTED (positions head down) for their use: ALL the
EXTINGUISHERS ARE USED WITHOUT INVESTING THEM, because to do they will
not work it. Extin is not due either to prove guidor
before using it inasmuch as it will lose its pressure and it will not
leave all its content. The extinguishers must be driven directly on
the fire to be really effective.
Or
located in front of the fire one is due to clear the safety thread and
the insurance or unites (he is a metal pin with a ring to hold the one
that the accidental unloading prevents), to turn robinete
(flying/drive disc) or to press the handle of the valve and to direct
to the unloading with movement of swing to the base of the fire,
taking the precaution TO ALWAYS MAKE the "SWEEPING" OF the
BASE Of the FIRE. The unloading more close possible is due to initiate
and to advance gradually towards the fire.
Once
extinguished the fire, although they are left rest of load in the
extinguisher is advisable to finish unloading them by two reasons: 1)
the fire can not be completely dull inside the burned objects, being
able to return to be uncontrolled (reignición effect) and 2) if the
drive is suspended, as already saying is had, is not possible to be
reinitiated. It is in many cases advisable of being possible to
approach the fire with more of an extinguisher, so that if is not
controlled it with first, is another equipment by hand to attack
without losses of time.
Also
it is recommended, of being possible, not attacking single the center
of fire, but next to another person.
When
the extinguished one has finalized is due to make recharge the
equipment immediately.
However,
beyond these brief advice on the use of the equipment, we have
prepared a synthesis of the questions more frequent than we received
from the users about the extinguishers and, with its answers, we hoped
to satisfy most of the doubts that habitually consider.
