Class-E: Electrical fire.

Q.3: Mention the different methods of fire extinguishing.

Ans: 1) Cooling                2) Blanketing                      3) Starving.

Lower down the              Stop or shutdown supply      Stop of shutting down the source

The temperature of oxygen.                              of fuel.

Q.4: Explain the following terms,

Flash Point: Minimum temp at which any chemical catches fire in presence of spark and continues to burn even after the spark (source of fire) is removed.

Flammable Mixture: Any flammable substance that after heating for some fire produces a mixture of gas (vapor), heat (temp) is called a flammable mixture.

Q.5: Classify the Personnel Protective Equipment:

Ans:   1) Respiratory PPE. Ex: SBA, Nose Mask.

 2) Non-Respiratory PPE. Ex: Goggles, Earmuff, Hand Gloves, Gumboots, Apron, and Boiler Suit.

 Q.6: Why do we provide jumpers and earthlings?

Ans: Jumpers are provided when two pipelines are joined by a flange. This results in a transfer of static charge developed between the liquid and metal surface to a safe point where it can be dissipated.

Earthing: Transfer of electric charge developed in potential equipment into soil or ground where there is no source water nearby.
