If the fire extinguisher is placed in the fire box, we must follow the guidance of professional personnel during operation, and strictly follow the rules for removal and placement to protect the rights and interests of users. The ambient temperature of the set location will have a significant impact on the spraying performance and safety performance of the fire extinguisher. If the ambient temperature is too low, the spraying performance of the fire extinguisher will decrease, and the extinguishing efficiency will also be affected. If the ambient temperature is too high, the internal pressure of the fire extinguisher will increase, posing a risk of explosion and personal injury. Therefore, the ambient temperature of the fire extinguisher setting point should be within the operating temperature range of the fire extinguisher.
The higher the fire hazard level, the smaller the protection area of the unit dose fire extinguisher. In order to facilitate and effectively extinguish initial fires, higher level fire extinguishers should be selected. For example, large wheeled fire extinguishers can be used in storage yards and garages. Jinan Fireproof Box Factory suggests that for places with low fire risk, such as office buildings and teaching buildings, fire extinguishers with low fire risk can be selected to avoid unnecessary waste.
Compared with the same fire extinguishing, Jinan Fire Equipment Factory said that the fire extinguishing effects of different fire extinguishers were very different: the amount of carbon dioxide and foam extinguishing agent was large, and the fire extinguishing time was long. The amount of dry powder extinguishing agent used is small, and the extinguishing time is short. According to the importance of the site, the requirements for fire extinguishing speed can be comprehensively considered.
Water, foam and dry powder extinguishers will cause raw water damage, foam pollution and dust pollution to varying degrees after spraying. For valuable equipment, instruments, cultural relics, and good electrical equipment, clean fire extinguishers such as carbon dioxide should be used, and low efficiency and obvious scaling effects should not be equipped. For projects with lower value, the impact of fire extinguishing agent pollution does not need to be considered too much.
