Thread Content

The comprehensive judgment rule of this article of "Major Fire Hazard Determination Rules GB35181-2025" says this: "6.4.5 The automatic fire alarm system is not set up in accordance with the provisions of fire protection technical standards, or it cannot be used normally. ”The automatic fire alarm system has the function of detecting fire information early, issuing fire alarms early, notifying personnel to evacuate, extinguish fires, or linking relevant fire protection facilities. Places or buildings with a large amount of combustibles, rapid fire spread, difficulty in putting out fires, or a large number of people staying at the same time are the basic areas where automatic fire alarm systems should be installed in industrial and civil buildings. One of the reasons for the particularly serious fire accident in Anyang Kaixinda was that the automatic fire alarm facilities and automatic fire sprinkler systems were not installed on the first floor, which caused a large amount of high-temperature and toxic smoke to spread rapidly along the stairs to the second floor. By the time the danger was discovered, the smoke had quickly filled the entire area, putting people on the second floor at risk.
