Fire fighting
1. How combustion takes place?
For combustion to take place three elements are needed. They are fuel, heat and
oxygen. This is called the triangle fire. Combustion can not survive without these
three. Remove any one of them, combustion ceases to take place. So wherever fuel,
oxygen and heat is there together combustion takes place.
2. How many types of extinction media’s are used in fire fighting?
a. Sand.
b. Water.
c. Foam.
d. Carbon – di – oxide.
e. Dry chemical powder.
f. Halons.
3. What are the classifications in fire?
a. Class A – Ordinary fire like burning of paper, wood etc.
b. Class B – Oil fire like burning of petrol, diesel, LPG etc.
c. Class C – Gas and dust fire like burning of butane, acetone, natural gas etc. and
burning of dust like uranium dust, sodium dust etc.
d. Class D – Metal fire like burning of uranium, thorium, sodium etc.
e. Class E – electric fire example transformer or switchgear fire etc.
4. How many types of fire extinguishers are there and state their suitability?
a. Soda acid type – suitable for Class A type of fires.
b. Foam type – suitable for Class A and Class B type of fires.
c. Carbon-di-oxide type – suitable for Class B, Class C and for Class E type of fires.
d. Dry chemical powder – suitable for Class B, Class C, Class D and Class E fires.
e. Halons BCF (bromo chloro difluoro methane) – suitable for Class A, Class B,
Class C and Class E types of fires.
5. At what areas of risk the Co2 flooding system, mulsifyre systems are provided?
Co2 flooding system is provided in diesel generator and turbine oil tank area.
Mulsifyre system is provided in generator transformer, start up transformer and unit
transformer areas.
6. What are the equipments kept inside the hose boxes?
a. Double female adapter (1 No).
b. Delivery hose pipe (50 feet – 2 Nos).
c. Branch pipe (1 No).
d. Valve wheel (1 No).
e. A hose box key (situated in a cabinet at side of hose box).
7. How water is used in a fire?
Water is used as a cooling effect in a fire.
8. How foam is used in a fire?
Foam is used as a blanketing effect in a fire.
9. Which extinguisher you use for electronic equipment fire?
Co2 or DCP type fire extinguisher can be used on fire involving electronic
equipments.
10. What you mean by starvation method?
Starvation method means elimination of fuel from the fire.
11. What is the name of powder used in Dry Chemical Powder extinguisher?
Sodium-bi-carbonate.
12. What you mean by cooling method?
Cooling method means elimination of heat from the fire.
13. What you mean by blanketing method?
Blanketing method means elimination of oxygen from the fire.
14. Why Co2 is used on Class E fire?
Co2 is a non-conductor of electricity.
