1 No. of Printed Pages : 11 BSEI-025 DIPLOMA IN FIRE SAFETY Term-End Examination December, 2012 BSEI-025 : INTRODUCTION AND ANATOMY OF FIRE Time : 3 hours Maximum Marks : 100 Note : Q. 1 All parts are necessary to attempt. Q. 2 any seven. Q. 3. Any three question are to be attempted. PART-A 1. Fill ups : 18x1=18 (a) All fires involve reaction. (b) Every Fireman should know how to fire. (c) is defined as something that possess weight and occupied space. (d) The lowest temperature at which it first gives off sufficient vapour for a flame is known as (e) Ignition temperature of yellow phosphorous is (f) Combustion is a rapid change accompanied by and (g) Three element and are essential to combustion. BSEI P.T.O.

2 (h) (i) (j) (k) Triangle of fire involves and The product of combustion can be divided into, and Such chemical reaction that produces heat is called reaction. Heat is most necessary to raise the BSEI-025 2

3 PART-B State True/False : 10x1=10 (a) (b) (c) (d) (e) (f) (g) (h) (i) (j) Oxygen is a reducing agent. Carbon monoxide is oxydizing agent. Fuel may be solid, liquid and gases. Such chemical reaction that absorbs heat is an Endothermic Reaction. Nitrogen is a reactive element. The temperature at which a solid melts is called the melting point of that solid. Vapour forms not only at surface of liquid but also in the wholc, body of the liquid. Tank storage is installed only above the ground. Fire of metal is categorised as class 'D' fire. Liquid fire is A class fire. ( ) ( ) ( ) ( ) 2. Attempt any ;even questions. 7x6=42 (a) (b) How will you identify a proper fire extinguisher to put off fire of all classes? Write a short note. Define coupling, monitor, adaptors and suction strainer. BSEI P.T.O.

4 (c) (d) (e) (f) What procedures will you adopt to put off the class 'D' fire? When one should not fight a fire. Write a short note on fuel, exothermic and endothermic Reaction with suitable example. Write down classification of fire by its size and also mention the stages of fire. Write down the properties of CO2 and DCP extinguishing agent. (g) By what way we can extinguish any fire? Write those methods. (h) What are the types of DCP Extinguisher? Explain each briefly. (i) (j) What different materials are used in not percolating Hose? Write a note for each of them. What is Suction Hose? Write a short note on its construction and care. 3. Attempt any three questions : 10x3=30 (a) (b) What are the three types of inter locking Hose coupling. Explain each. Enumerate the characteristic of Hose. BSEI-025 4

5 (c) (d) (e) Which two main types of Suction Hose are in general use? Write in detail. What fire fighting techniques should be adopted to put off fire? Write pointwise. Explain the term "Triangle of fire" in detail and what type of extinguisher can be used on electrical fire? BSEI P.T.O.
