Xiao Bian talks to you about fire safety information he knows, those things in the fire district
The zoning inspection of fires in public gathering places is very important. An effective and effective fire prevention zoning facility will ensure that when a fire occurs, the spread of fire will be effectively controlled. In the past during fire safety inspections, we often neglected the inspection of building fire prevention zoning facilities. There are many lessons. In the inspection, not only horizontal separation but also vertical fire separation measures should be observed.
General problems with fire partitioning systems:
1. The understanding of the building's fire partitions was erroneous and did not recognize that the fire partitioning was a space concept. The separation facilities on the management plane are very careful, but vertical separation measures, such as fire blocking between the floors, are not noticeable; there is a space short-circuit caused by the stairs between the floors, and there are no pipeline wells in the high-rise buildings. Notice that blocking measures have been taken. There are too many lessons of this kind.
2. Dump debris or counters under fire shutters, affecting take-off and landing;
3, fire door deformation, fire window damage, affect the separation function;
4. There is no or lack of fire dampers on the ventilation ducts, air conditioning ducts, and smoke exhaust duct systems, or the fire dampers fail.
5, normally open or normally closed fire doors, fire shutters have not been maintained in the design position. Automatically controlled solenoid valve failure or failure.
6. The fire door group does not have a closed-door sequencer or is damaged.
