| Title | The Study of the Size of the Attack Hose Affects the Maneuverability of Apartment Fire Rescue-Case of Haishan Branch | ||
| Keyword | |||
| Abstract | A fire hose is a common appliance used by firefighters to connect the water to the fire scene to extinguish a fire by cooling. Different sizes of fire hoses would perform different volumes of discharged water flow; however, the weight, friction, and flexibility of the hoses also differ. When firefighting in the apartment building, in which the fire load is relatively small and requires smaller water flow, using large sizes of hoses could cause problems including the hose stream overweight, creating sharp bends of the hoses, the excessive amount of water current. These problems increase fire fightersˇ¦ operation loading and create large water damage in the fire scene that affect the fire rescue efficiency. This study discusses the characteristics of apartment building fire through literature review and field operation analysis. Through the actual operation of different sizes of attack hoses in the field, the study analyzes the suitable size for the apartment building fire based on the Needed Fire Flow of the apartment buildings. The study aims to increase firefightersˇ¦ mobility and flexibility and shorten the deployment time to prevent fire from increasing to increase the rescue efficiency. In this test, it can be found that the increase in the size of the hose increases the weight by 1.83 times, the drag force by 2.10 times, the operation time by 1.72 times, and the total air consumption by 2 times, which obviously affects the mobility of rescue. |
