barium nitrate
Ba(NO₂)₃    fw=261.36

Hazards

Poisonous! Avoid contact.

Ingestion may cause excessive salivation, vomiting, violent diarrhea, convulsive tremors, increased blood pressure, hemorrhages in G.I. tract and kidneys, and muscular paralysis. (21)

Emergency Procedures

If contact with skin occurs, wash for at least 15 minutes with water.
If ingestion occurs, provide gastric lavage followed by saline catharsis. Call physician. (21)

Toxicity

Exposure limits, acute, cancer and reproductive effects:
The threshold limit value for barium nitrate is 0.5 mg/cu meter of air as barium. (21)

Contact MLD (rabbit) 500 mg/kg (3)
Inhalation ()
Ingestion LD50 (rat) 355 mg/kg (21)

Flammability and Explosion Hazard

Warning! Nitrate furnishes oxygen for other combustibles. (21)
Keep nitrates away from other combustibles. Mixtures with finely divided aluminum-magnisium alloys are easily ignitable and extremely sensitive to impact. (21, 3 )
