Backfire occurs when the fire goes where?

Out completely
Back into the tip
Around the hose
Into the regulator

The correct answer is: Back into the tip

Firefighting tools, like hoses and pumps, are used to control and direct the flow of water in order to extinguish a fire. When a fire is burning, it creates a stream of hot gases that rise up from the flames. These hot gases can be pushed back towards the firefighter by the pressure of the water coming out of the hose, causing what is known as backfire. This is dangerous because it can put the firefighter in harm's way and also make it more difficult to control the fire. Choosing option B, "Back into the tip," correctly identifies where the backfire occurs at the tip of the hose where the water is being directed. Options A, C, and D are not correct because they do not accurately describe the location of the backfire. Therefore, they should not be chosen as the correct answer.
