Helicopter Brush Firefighting

Introduction

Helicopter fire fighting apparatus includes a large quick-connect and disconnect fire-fighting fluid tank, a pump climbed on near the motor, a fire fighting command station on the rear of the helicopter and a nozzle broom swiveled near the command station. A helicopter lands, rapidly drops an empty tank and hooks up a full tank before rising to the correct location to battle a fire, such as in an agency building. The rise breaks windows for access to the fire, and a hardened water-driven projectile may be propelled from the nozzle rise to break a window.(Alvarado, 1998)
