Should dry powder or carbon dioxide be used in the distribution room

The selection of dry powder fire extinguishers or carbon dioxide fire extinguishers for extinguishing fires in the distribution room depends on the specific scenario. Dry powder fire extinguishers are suitable for extinguishing various types of fire sources, while carbon dioxide fire extinguishers are more suitable for electrical equipment fires.

Dry powder fire extinguishers have a wide range of applications and can effectively extinguish fires caused by solid, liquid, gas, and electrical equipment. Dry powder fire extinguishing agents mainly interrupt the combustion chain reaction through chemical inhibition, and the residue after extinguishing may cause pollution to precision equipment. Dry powder fire extinguishers are easy to operate and have a long spraying distance, making them suitable for mixed fires that may occur in power distribution rooms. After use, it is necessary to clean the site in a timely manner to avoid dust accumulation that may affect the operation of the equipment. Carbon dioxide fire extinguishers extinguish fires by reducing oxygen concentration and cooling, leaving no residue after extinguishing, making them particularly suitable for protecting valuable electrical equipment. The use of carbon dioxide in confined spaces may pose a risk of suffocation, and ventilation conditions should be taken into account during operation. Carbon dioxide fire extinguishers have limited effectiveness in extinguishing deep fires and are more suitable for extinguishing surface fires. When equipping fire extinguishers in the power distribution room, consideration should be given to the type of fire, equipment value, and environmental conditions. The pressure and expiration date of the extinguishers should be regularly checked, and employees should be organized to conduct fire drills. It is recommended to post operating instructions in a prominent location in the power distribution room, keep the fire escape clear, and install smoke alarms and automatic fire suppression systems as supplementary protective measures.
