Finely divided barium is susceptible to rapid, violent combination with atmospheric oxygen. Therefore, in powdered form it must be considered pyrophoric and very dangerous to handle in the presence of air or other oxidising gases. Barium powder must be stored under dry argon or helium to avoid the possibihty of violent explosions. Massive pieces of barium, however, oxidize relatively slowly and present no explosion hazard if kept dry. [Pg.472]

Hazard Flammable (pyrophoric) at room temperature in powder form store under inert gas, petroleum, or other oxygen-free liquid. When heated to approximately 200C in hydrogen, bariumreacts violently, forming BaH2. TLV for all soluble barium compounds, 0.5 mg/m3 (as barium). [Pg.121]

ARTIC (74-87-3) Flammable gas (flash point <32°F/<0 C). Moisture causes decomposition. Violent reaction with strong oxidizers, acetylene, anhydrous ammonia, amines, fluorine, interhalogens, magnesium, potassium, sodium, zinc, and their alloys. Reacts with barium, lithium, titanium. Contact with powdered aluminum or aluminum chloride forms pyrophoric trimethylaluminum may cau.se ignition or explosion. Attacks plastics, rubber, and coatings. [Pg.138]

BENSULFOID (7704-34-9) Combustible solid (flash point 405°F/207°C). Finely divided dry materia forms explosive mixture with air. The vapor reacts violently with lithium carbide.
