FIRE HAZARDS AND PREVENTION

CLASS  OF FIRE

CLASS A - General combustables ( wood, paper,
   cloth,rubbish)
CLASS B - Inflammable liquids (oil, petrol,grease, paint)
CLASS C - Gases ( Acetylene, LPG)
CLASS D - Metals ( Magnesium, Potassium, Sodium)
*** Electrical fires are coming under different groups depending upon the source of fuel. First put off the supply & attack the fire.

Essential facts on fire to help you take an informed
decision on your fire protection needs.



It takes only few minutes for a fire to move from ignition stage to an uncontrollable blaze. Once ignited, a fire moves rapidly and with increasing intensity through three stages . As the fire grows geometrically, it requires increasing quantities of extinguish agent to fight it.





Essential facts on fire to help you take an informed decision on your fire protection needs


1st Stage


THIS IS THE ONLY STAGE AT WHICH
 A FIRE EXTINGUSHER CAN BE  USED:
At the first stage (extinguishing capability by a fire extinguisher), fire move from ignition phase to the blaze phase. Depending on the type of the fire, this can take anything from 1 to 10 minutes, and unless controlled instantly, spreads quickly.


2nd Stage

THE ONLY SOLUTION IS SOPHISTICATED
SPRINKLER SYSTEMS WHICH WOULD BE
ABLE TO DISPENSE 100`S LITRES (KGS) OF
EXTINGUSHING AGENTS.
At the second stage (extinguishing capability by sprinkler system), the fire spreads rapidly over large areas. Increasingly large volume of the extinguishing agent are necessary to fight the growing intensity of the fire. Fire extinguisher cylinder become useless as the power capacity is limited.

3rd Stage

AT THIS STAGE ONLY THE FIRE BRIGADE
CAN HELP. NOT SO MUCH TO PUT OUT THE
 FIRE IN YOUR PREMISES BUT TO PREVENT
 IT SPREADING TO NEIGHBOURING
 PROPERTIES.
At the third stage (extinguishing capability by the fire brigade), the fire has moved beyond control and will require 1000`s of litres (kgs) of fire extinguishing agent.

Types Of  Portable Fire Extinguishers


1. Water - Class A
2. Foam - Class B
3. Carbon Di Oxide (CO2) - Class B & C
4. Dry Chemical Powder (DCP)- Class B,C,D
5. Halon - Class B & C

PREVENTION IS 
BETTER THAN 
CURE

  
WORLD’S 

LARGEST
 FIRE        
  CAN BE PUT
 OFF BY
 POURING A
