The minimum conditions
which are demand for occuring the flame or continuing and spanning
the fire,there has to be a purview as called as "Fire Triangle".
The Fire Triangle has been given above:
If it is allowed to finished this triangles in one way, fire
occurs and it can be a reason for increasing the fire during
the triangle's one edge doesn't exist. If there ae the triangle's
any of two edges and the third one is not, fire can't occur.
It can't give any result as a fire everytime because air (oxygen)
that covers all the world and can possibly be found every place.
Moreover, if it is thought the flammable gases have the possibilty
to be found in some studying conditions, it is going to be suitable
to throw the triangle's other edge out that has the minimum
heat and energy as an ignition source for this kinds of conditions.
In addition, it gets the demand of EX-PROOF materials that
are changeable quality according to condition and used for establishing
electric systems in flammable conditions.
The field of producing flammable gas,vapour or liquids, using
them during production process or stocking them is called as
"Dangerous Area". It is suggested to use EX-PROOF
materials in Dangerous Areas nowadays.
CLASSIFICATION OF DANGEROUS AREAS
According to flammable and explosive atmosphere:
