I'm a volunteer fireman. I'm also simplifying, but you usually don't need to spray a continuous stream of powder, bursts take away the oxygen and cover the burning surface. In addition to lasting a bit more, of course

Then again, there are a few misconceptions about fire extinguishers that come from films and movies: they're effective on small fires, to choke down a fire at the beginning, once the fire catches, you need other ways to fight it. And a lot of fires what can be extinguished with an extinguisher can be choked with a fire blanket. Which isn't as exciting to show in a TV show xD
