FED-STD-791D
b. First Aid:Irrigate eyes with water. Wash contaminated areas of body with soap and
water. Supply oxygen, with use of intermittent positive pressure breathing
apparatus. Call a physician.
Spills:
Neutralize with dilute sulfuric acid. Wipe with mop or use water aspirator.
Drain into the sewer with sufficient water.
005 Ammonium nitrate NH4NO3
Synonyms: Nitric acid, Ammonium salt, Nitram.
Life Hazard: The oxides-of-nitrogen gases (except nitrous oxide - N2O) emitted on
decomposition of ammonium nitrate are extremely toxic. Any person
exposed to such fumes should receive immediate medical attention.
Hazardous reactions: ignites by heating its mixture with combustible
materials; ignites in the presence of zinc powder and water; explodes by
impacting its mixture with ammonium sulfate.
Flammability: Oxidizing agent; supports combustion and is capable of undergoing
detonation if heated under confinement or if subjected to strong shocks.
Melts at about 150C with slow decomposition; near 300C, the
decomposition accelerates with sudden rushes of light-brown to
orange-copper fumes, indicating that the decomposition may become
explosive. Self-ignition of mixtures of ammonium nitrate with easily
oxidizable organic materials or easily oxidizable, finely divided metals
may take place at moderately elevated temperatures.
Handling: Separate from all organic materials or other contaminating substances such as
flammable liquids, acids, corrosive liquids, organic chemicals, chlorates,
sulfur and finely divided metals or charcoal, coke, and sawdust. Wear rubber
gloves and chemical goggles.
Emergency: Treatment and Measures:
a. First Aid: When exposed to nitrogen oxides due to decomposition at high
temperatures, individuals should be promptly given treatment by physician.
b. Fire Precautions (In case of outbreak): Flood with sufficient amount of water.
Exercise extreme caution in application of water on fused or molten material to
avoid eruptive scattering and spread of fire.
Spills:
Sweep into a beaker. Dilute with sufficient water. Add soda ash. Mix and
neutralize with dilute acid. Drain into the sewer with abundant water.
006 Barium chloride BaCl2
2H2O
Synonyms: Barium chloride dihydrate.
