Hazards and Protection.
Keep in a cool, dry location. Keep container tightly closed.
Handle in a controlled, inert atmosphere.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stable at normal temperatures and pressures if kept in a tightly sealed container.
Water, steam, moisture and air.
Ammonia gas, barium and oxides of barium.
USE: Class D or other metal extinguishing agent. DO NOT USE WATER. Wear a full face self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Barium nitride reacts violently with air or water. Dangerous: explodes upon heating and by spontaneous chemical reaction with water liberating ammonia vapors which can form explosive mixtures with air.
Fire may produce irritating, corrosive and/or toxic gases.
May cause gastrointestinal disturbances, muscular spasms and acute barium poisoning. Ammonia gas may cause nausea, vomiting and burns.
May cause irritation to the upper respiratory tract, a slow pulse, extrsystoles, hypokalemia and acute barium poisoning. Ammonia gas may cause irritation to the nose and throat, dyspnea, bronchial spasms, chest pain, pulmonary edema and pink frothy sputum.
May be an irritant and possibly corrosive. Ammonia gas may cause irritation and chemical burns.
May be an irritant and possibly corrosive. Ammonia gas may cause severe irritation and chemical burns.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
