Can some matters in the
forest be ignited without
human interference?
Roles of the forest
Home for animals, their natural habitat,
Lungs of the Earth-trees produce oxygen necessary for
organisms to live,
Shelter for birds and other animals (squirrel, wild boars,
deer, foxes, hares,wolves, bears),
Fuel for winter,
Source of wood to manufacture paper,
Source of wood to manufacture furniture,
Place of entertainment, to meet friends, to pick
mushrooms, to go for a walk and to organize picnics.
Fires are a natural
phenomenon on our planet.
They are caused by long
droughts or thunderbolts and
they are used to regenerate
vegetation. Today most fires
are caused by people
especially in tropical regions.
Causes of Fires
Natural
Intentionally
(Spontaneous): stimulated:
Wind,
Thunders,
Drought,
Vulcanic eruption
(burning lava),
Self-ignition
By human’s will:
• Crash of electrical
installation,
• Gas,
• Petrol
Fires caused by people can be the
consequence of carelessness or
malice. Often they result from a
planned and organized change in
using land. Especially in tropical
regions, big areas of humid forests
are burnt to gain some land to
grow plants and vegetables.
Self-ignition
Explanation a spontaneous,
without the initiating impulse of
energy from outside, reaction
started by burning mixtures of
gases, liquids a substances with
oxygen or air. It’s caused by
throwing glass materisls, heated
metal and other flammable
materials.
Many Scientists claim that as a
consequence of climate
changes in connection with
the changes in rain and
temperature the number of
forest fires will increase in
their frequency and
occurance.
Extinguishing fires can
happen from land and air. The
Impediments can be weather
conditions for example wind
and droughts problems with
access to water, the size of
the fire, not enough firemen.
To extingnish forest fire we can
use:
•
•
•
•
•
•
•
•
Water,
Special Foam,
Special Powder,
Special Gas,
Chloride,
Graphite,
Sand,
Azote.
