Knee sit
__________ master streams are most commonly used in defensive operations ?
Elevated
All nozzles Lose some effectiveness when they are not _________ their rated flow ?
Discharging
__________ are not as affected by wind conditions nor are they as effective for rapid steam conversion as are fog streams ?
Solid streams
The best way to effect a ___________ with an elevated master stream is to try and deflect water off the ceiling of the fire room ?
