(2) For fire not caused by batteries. • If the fire is s mall and has not spread to the high-voltage battery yet, use CO2 or ABC dry powder fire extinguisher to put out the fire. (3) For battery-related fire. • If the high -voltage battery is bent or damaged in the fire, or if a battery-related problem probably occurs, use a large amount of water to put out the fire. • It may need 24 hours to completely put out a fire in batteries, and with a thermal imaging camera, it can ensure that the high-voltage battery is completely cooled before the accident comes to an end. If no thermal imaging camera is available, it is necessary to monitor the batteries for re-ignition.
If there is smoke, it indicates that the battery is still hot, and in this case, the monitoring shall be maintained until at least one hour after the battery no longer smokes. • To avoid hidden danger caused by re -ignition of the batteries, it is recommended to place the battery in an open area. (c) Precautions against electric shock. (1) Suppose that all high-voltage components are energized all the time! (2) To avoid electric shock, do not directly contact any part of the vehicle, and always use insulating tools. (3) Cutting, crushing or touching high-voltage components can cause serious electric shock or a short circuit. (d) Other precautions.
(1) The battery may release toxic gas when it catches a fire, thus unrelated personnel must be evacuated. (2) You must have an awareness of self-protection, wear protective equipment, and do not inhale toxic fumes. (3) Inflatable bottles for storing gases, gas pillars and other components can have an extreme temperature that may exist when boiling liquid becomes steam and explodes. Before the "hot zone" of the accident is inspected, disassembly must be implemented appropriately with protections provided. (4) Do not use CO 2 extinguisher to put out the fire on a person, as there is a danger of suffocation. 5.
Precautions for faulty vehicle (a) Employees wearing auxiliary electronic medical devices shall not get close to the faulty vehicle. When the motor or the high-voltage system is in operation, the following auxiliary electronic medical devices may be negatively affected. • Analgesic pump in human body. • Implanted defibrillator. • Pacemaker. • Insulin pump. • Hearing aids. 2
