Exploded NiCd Batteries
While attempting a home-charge of a set of NiCd batteries, they were
left unattended and consequently exploded (relatively high current was flowing through them). The basement area in which the explosion took place is currently being ventilated overnight. Does anyone have any recommendations for further safety precautions or clean-up procedures? Thanks |

The chemicals you're dealing with in a typical Ni-Cad battery a Nickel & Nickel Hydroxide Cadmium & Cadmium Hydroxide Sodium Hydroxide Potassium Hydroxide Cobalt Hydroxide I would wear rubber gloves when cleaning this stuff up! Wipe down all surfaces and rinse with water. Dispose of all cleaning materials. The potassium hydroxide (35%) is the worst component in NiCd batteries. Rinse splattered areas with as much water as you can. |

Exploded NiCd Batteries
Thanks for the suggestions guys.
I especially like the "follow manufacturers instructions" part. Just need to overcome my "reading inhibitions". :-)ooo FWIW, this happened because I was doing a fast charge. I'm usually very careful to stop the process as soon as there is any heat. But this time I got called to dinner when I should have been watching the stew. Actually more like pop-corn! On a more serious note, I am reminded about how familiarity breeds contempt and can often lead to compromising safety. Anyway, cleaned up the mess. No real harm seems to have been done except I prolly blew up about $60.00 worth of nicad cells. DOC Have robots. Will travel. http://www.robot-one.ca Dr. Anton T.

Rinse splattered areas with as much water as you can. And, in times to come, it might be wise to follow the battery manufacturer's recommendations for charging procedures, especially the current level. If you're paranoid, you can rig a sort of "charging chamber" with some hollow-center cinder blocks. That will at least confine the damage if it happens again. I'm guessing no one was hurt.
