PROSSER, Wash.- You hear the word contained a lot, but just because a fire is contained doesn't mean it is out, it still may be aggressively burning.
Containment simply means firefighters have built fuel breaks around the fire.
Those breaks can be burn outs, fire lines or natural barriers like a river.
"The people on the ground and also aerial aircraft dropping retardant, that stops the fire," said Dale Warriner, a fire information officer.
A fire is not actually out until it is deemed controlled.
All flare ups must be out and the fire 100 percent contained.
