Answer:
Smothering and Starving
Step-by-step explanation:
1. Smothering:
This is one of the effective method for extinguishing of a petrol fire. It can be achieved by removing the oxygen from the atmosphere by applying a blanket of foam over burning surface. This will help in introducing carbon dioxide (CO2) and inert gas to the immediate vicinity of the fire help in fire control.
2. Starvation:
Here, fire can be extinguished simply by removing the fuel source, accomplished in a number of ways such as stopping the flow of liquid or gaseous fuel, removing solid fuel in the path of the fire or allowing the fire to burn until all of the fuel is consumed.
Both these methods are effective for extinguishing a petrol fire.
