Wear rubber gloves, face shield and laboratory coat. Have an all purpose canister respirator available.
SPILLS: A liquid solution - absorb on paper. Evaporate in an iron pan in a flame proof fume hood then burn the paper.
A solid - sweep on to paper and place in an iron pan in a fume hood. Burn the paper and compound.
