Shredding batteries - GIF

Just a little fire hazzard.

If they are lithium batteries then the fire hazard is of the order of 4000 degrees C, and my understanding is that the only way to put it out is to wait for it to burn out.

That's a really really really! bad idea.

I Just finished some training on lithium battery safety last week.

First thing you do is evacuation, next call 911, then stay upwind and as far away as possible. Let the fire department deal with it.

For lithium metal batteries like these, a powdered copper filled extinguisher is recommended. (or graphite powder filled )
The powder starves it from oxygen, the heavy copper sucks heat up to cool it down.
Then let a professional do the cleanup.

Lithium Ion batteries are somewhat safer, but still, let professionals do the cleanup.

I know nothing of the professional opinion of extinguishing lithium fires, but as they found out at Chernobyl, ya'all cant extinguish a graphite fire.

Types of Fire Extinguishers DRY POWDER D Combustible Metals • Class “D” fires. • Sodium chloride, copper, or graphite based. Some handle multiple types of metals, others will not. 6 -8 ft. maximum effective range. Low velocity nozzles or discharge wands apply gently to avoid disrupting finely divided burning materials. • • Extinguishes by cooling and smothering. Powder will act as a heat sink, while forming a crust that cuts off oxygen supply.

Apparently Graphite fire extinguisher work better on magnesium fires than lithium, but still do some good depending on the battery chemistry.
