Fire hazards are a big concern in city residential buildings. Many buildings have overloaded electrical circuits, which can lead to fires. Sometimes, heating systems aren't properly maintained, increasing the risk. Also, not all buildings have enough fire extinguishers or smoke detectors. Fire exits and stairwells can be blocked, making evacuation difficult. Plus, many residents don't know the fire evacuation procedures, which is risky.
火灾隐患在城市住宅楼中是一个大问题。许多建筑物的电路过载,可能引发火灾。有时,供暖系统维护不当,增加了风险。此外,并非所有建筑都有足够的灭火器或烟雾探测器。消防出口和楼梯间可能被堵塞,导致疏散困难。而且,许多居民不了解火灾疏散程序,这非常危险。
