When a lithium-ion battery ignites, it is essential to promptly and effectively implement extinguishing measures to ensure safety. Firstly, swiftly identify the fire's origin and endeavor to relocate the burning battery to a secure area, away from flammable materials and crowded spaces, in order to prevent the fire from spreading and causing harm. Exercise extreme caution during the relocation process to avoid impacting or compressing the battery, as this could exacerbate the fire.
It is imperative to note that water should not be directly used for extinguishing a lithium-ion battery fire due to its potential for inducing internal short-circuiting within the battery, leading to an intensified fire or even an explosion. Instead, select an appropriate fire extinguisher. Dry powder and carbon dioxide extinguishers are two common options capable of effectively cutting off oxygen supply and quenching flames. When using them, aim directly at the base of the fire and continue spraying until all flames are completely subdued.
Throughout the extinguishing process, maintain a safe distance and wear protective gear such as flame-resistant clothing, gloves, and a mask in order to mitigate exposure risks from the extinguishing agent. Concurrently monitor closely for any changes in the fire's behavior. If it becomes unmanageable or poses other safety hazards, evacuate immediately and seek professional assistance from firefighting services.
Furthermore, after successfully putting out a lithium-ion battery fire through proper means of extinction methods with selected equipment mentioned above; continuous monitoring of its condition is necessary in order to prevent re-ignition risk. Use water-based extinguishers or ample water resources for cooling down until complete cessation of heat generation occurs within affected batteries. Additionally conduct thorough cleaning at scene location post-extinguishment activities aimed at eliminating residual ignition sources while ensuring overall safety standards are met.
In conclusion: when dealing with a lithium-ion battery ignition event - adhere strictly towards correct implementation of designated extinction procedures; selection & use of suitable firefighting equipment; maintaining safe distances throughout operations whilst wearing prescribed protective gear; prompt evacuation if situation escalates beyond control followed by seeking professional help.
