Brandon;
We have found lime to be a good extinguishing agent for such materials.  It is kept in a 2 or 5 gallon plastic bucket in the lab with a lid.  A large plastic scoop is used to apply the material to a fire.

DCHAS,

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.

Regards,
