Hazards and handlingac of lithium battery

Due to a large amount of energy inside a lithium battery, potentially dangerous situations can occur. The main cause of this danger is the internal or external overheating of the sealed battery (short circuit inside or outside the battery). Overheating will cause the dielectric fluid to expand beyond its capacity, increase the hydrostatic pressure in the tank, and eventually cause the battery to explode. If the battery has caught fire or exploded, take the following measures:

1) On-site personnel hold their breath and do not directly touch the liquid with their hands.
2) Wear safety clothing (full body suit, rubber gloves, boots, gas mask, and face shield (good enough to cover the goggles)).
3) Do not use water, damp sand, carbon dioxide, or soda powder fire extinguisher to put out the flame, but use one (D-grade graphite fire extinguisher).
4) Keep all irrelevant personnel away from the device. And try to work outdoors as much as possible.

Lithium battery fire or explosion health hazard data

1) The main way of harm: inhalation
2) Health hazards: its steam has strong irritation to the skin, eyes, and mucous membranes, and the symptoms: the eyes and mucous membranes are irritated.
3) Regarding eye treatment: flush eyes with running water for at least 15 minutes; pull eyelids away from eyeballs; seek medical attention immediately.
4) Regarding skin treatment: rinse with plenty of running water. If skin burns, seek immediate medical attention.
5) On inhalation: Remove to fresh air. If breathing is difficult, use an oxygen cylinder and seek medical attention.
6) If ingested: seek medical attention.

Manufacture and dismantle battery nipples in the workshop and on-site

1) Lithium batteries are not rechargeable, and it is dangerous to apply opposite voltages to them.
2) When making battery nipples on-site and in the workshop, please carefully check the polarity of each battery nipple to ensure that the battery is connected to the upper and lower connectors of the battery correctly.
3) If it is found that the temperature of the battery unit or the short section is very high, overheated, or damaged during the normal assembly of the battery or in the case of unknown reasons, it must be stopped immediately. Immediately put on safety clothing, rubber gloves, and place the battery nipple outdoors in plenty of water or flush it under a tap for at least 24 hours. This is the best and safest way to dispose of batteries.
4) If the battery short section has been scrapped, it should be handed over to the relevant personnel in time to fully discharge it, and the on-site personnel should transport it back to the warehouse in time. It should be noted that the battery cannot be 100% discharged. Therefore, care must be taken in the subsequent processing steps.
5) In the process of underground work, when the battery nipple has broken or overflowed, it is possible that one or more battery cells have been damaged. After taking out, flush the battery with water to completely complete any chemical reaction and reduce the temperature, so that it can be disposed of safely. Short battery. Never try to disassemble any battery cells, or apply too much mechanical stress when handling the lithium battery cells or short sections.

When handling damaged or overheated battery shorts, the following steps should be followed:

1) Keep all irrelevant personnel away from the device.
2) Work outdoors.
3) Use the correct fire extinguishing materials (sodium carbonate and LITH-X graphite powder for Class D fires)
4) Wear safety clothing (full-body protective clothing, rubber gloves, and boots, gas mask, and face shield (preferably covering goggles))
5) Rinse the broken sub joint with water until the chemical reaction is completely completed and the sub joint has cooled down.
6) Disassemble the pool nipple, insulate the damaged nipple, and dispose of it with the correct method.
