2016 Building Fire Extinguisher Configuration Design Specification

This article introduces you to the configuration options for building fire extinguisher configuration design specifications.

A civil building can be divided into two categories: public building and residential building. It is more complicated than industrial building in the classification of fire hazard level, but it should mainly be based on the nature of the fire extinguisher configuration, the intensity of personnel, and the amount of electricity used. The risk level is divided by factors such as the amount of combustibles, the speed of fire spread, and the difficulty of fighting.

Building Fire Extinguisher Configuration Design Specification - Configuration Options

It is generally recommended to select the fire extinguisher of the applicable type, specification and type according to the following six factors:

1. According to the type of fire in the place where the fire extinguisher is installed, it can be determined which type of fire extinguisher should be selected. If you choose an unsuitable fire extinguisher, it may not only extinguish the fire, but it may also cause a chemical reaction to the combustion of the fire extinguishing agent, and even an explosion and injury.

2. According to the hazard level of the fire extinguisher configuration site and the type of fire, the protection distance and configuration reference of the fire extinguisher can be determined. This is the first step in designing and calculating the fire extinguisher configuration.

3. The fire extinguishing effectiveness and versatility of the fire extinguisher should be considered when selecting a building fire extinguisher.

4. In order to protect valuable materials and equipment from unnecessary stains, the choice of building fire extinguisher configuration design specifications should consider the degree of fouling of the protected items. Water-type fire extinguishers and foam fire extinguishers also have similar fouling effects. The use of gas fire extinguishers to extinguish fires, not only does not have any remnants after fire extinguishing, but also has no fouling or corrosive effects on valuable and precision equipment.

5. The ambient temperature at the set point of the fire extinguisher has a significant impact on the fire performance and safety performance of the fire extinguisher. If the ambient temperature is too low, the fire-extinguishing performance of the fire extinguisher will be significantly reduced. If the ambient temperature is too high, the internal pressure of the fire extinguisher will increase sharply, and the fire extinguisher will be in danger of blasting and injuring people. This paragraph requires the ambient temperature of the fire extinguisher set point to be within the fire extinguisher operating temperature range.

6. The fire extinguisher is operated by humans. The design specification of the building fire extinguisher is especially important. The physical fitness of the personnel in the site should be analyzed, and then the type, specification and type of the fire extinguisher should be correctly selected. Generally, in different civil construction sites, medium and small portable fire extinguishers are widely used. In the large workshops of industrial construction sites and the halls of ancient construction sites, large and medium-sized portable fire extinguishers or pushers may be considered. Car fire extinguisher.

The correct selection of building fire extinguishers is the key to building fire extinguisher configuration design specifications. We must strictly follow the relevant provisions of international standards and foreign standards, and determine it based on decades of domestic firefighting experience and experimental verification. The new building fire extinguisher shall be designed and calculated according to the principle of equivalent replacement and the provisions of this code. Portable fire extinguishers and stroller fire extinguishers can also be selected in the same place when conditions permit.
