补充一下,对于机械场所,貌似能满足30分钟持续供水就可以了,没说必须。
对于使用过程中压力会降低的,五分钟内要有第二种满足要求的灭火系统
能加海水应该也可以,毕竟安全第一
The system should be available for immediate use and capable of continuously supplying water for at least 30 min in order to prevent re-ignition or fire spread within that period of time. Systems which operate at a reduced discharge rate after the initial extinguishing period should have a second full fire-extinguishing capability available within a 5-minute period of initial activation. |
