TYPICAL CLASS III FIRE HOSE STATION
![Page 8: Fire protection system ax 272 f](https://reader035.vdocuments.us/reader035/viewer/2022062515/55c499a7bb61ebd34f8b4882/html5/thumbnails/8.jpg)
OPERATION OF FIRE HOSE STATIONS
1. Open valve completely
2. Pull hose entirely off rack
3. Open nozzle
THREE STEPS FOR OPERATION
![Page 9: Fire protection system ax 272 f](https://reader035.vdocuments.us/reader035/viewer/2022062515/55c499a7bb61ebd34f8b4882/html5/thumbnails/9.jpg)
1. Open valve completely.
