The response to lithium battery fires mainly includes two aspects: rapid fire extinguishing and efficient cooling. Rapid fire extinguishing is to significantly reduce the thermal damage caused by flames to adjacent batteries and other equipment; efficient cooling is to suppress the chain decomposition reaction inside the battery, prevent the battery from re-igniting and thermal runaway, and can also effectively reduce the impact on adjacent batteries. Among the fire extinguishing agents, perfluorohexanone has shown the ability to quickly extinguish open flames outside the battery. It has a high safety margin and is friendly to the environment. After eruption, it can quickly vaporize, quickly absorb a large amount of heat, and isolate oxygen in the air, to achieve suffocation and fire extinguishing. The inadvisability of water firefighting is determined by the characteristics of lithium batteries. When a fire breaks out in a lithium battery, moisture may cause the battery to short-circuit, thereby exacerbating the fire. In addition, water reacts violently with the positive and negative electrode materials and electrolyte of lithium batteries, and the gas and heat generated may cause explosions and aggravate fire accidents. Some people also believe that water can be an effective means to extinguish fires and suppress re-ignition. Regarding the cause of the lithium battery explosion, the industry insider pointed out that the safety of the lithium battery itself has been verified in many aspects, and this incident may be affected by many factors such as the external environment. The specific cause needs to wait for the investigation results.
According to Singapore’s Lianhe Zaobao, the data center is located on Luoyang Avenue and is owned by Digital Realty, an American data center real estate investment trust.
