Spring has arrived; we invite all members of Haichuan Network to actively participate in the activity titled 【Spring has come to Haichuan Chemicals】, and to share photos of the spring scenery from various places. We’re waiting for you!
In the event of a fire, it is possible to pump out the circulating water in a timely manner!
Insufficient pressure and low water level are even more worrying. . .
My first impression was an inability to fully empty my bladder.:L And it’s obviously not water or piping designed for firefighting purposes.:L
Failing at the critical moment.......
What are you still gesturing at over there? Isn’t this a shame? It shows a severe lack of fire-fighting facilities, as well as the absence of emergency drills on a regular basis.
The fire water pressure should not be lower than 0.6 MPa
Fire water must have a return circuit, its pressure must be maintained, it must be used separately, and there must be a backup diesel water pump
How could it be this high? Generally, for category II high-rise and multi-story civil buildings, the static pressure at the outlet of the fire hydrant at the most unfavorable location should be no less than 0.07 MPa. For category I high-rise and industrial buildings, this value should be no less than 0.1 MPa, while for super-high-rise buildings, it should be no less than 0.15 MPa
I want to do it, but I don’t have the strength; I feel drained. . .
