For lab scale use 1-2 kilos of sodium bicarbonate in the hood is adequate. Only use large equipment for large scale operations.

Many years ago I worked at a facility where a process using several kg of molten Li was being developed. A lot of graphite dispersed in a light oil was used as an extinguishing agent, although I never observed it in use. I was told at the time that the reaction Li(liquid)+C is endothermic.
I am looking into the advantages and disadvantages of using Met-L-X or Lith-X scoopable dry powder extinguishing agent versus outfitting labs with the extremely large dry powder extinguishers that this material traditionally comes in. I am hoping for a solution for the usual pyrophoric and reactive metal suspects; alkyllithiums, trimethyl aluminum, diethyl zinc, potassium, sodium, magnesium, etc.
If anyone has an experience with using or training with this extinguishing, I would appreciate any insight that you might have. I have already contacted Ansul and am awaiting their response.
