ADDITIONAL INFORMATION
MIXTURES OF SODIUM NITRATE WITH POWDERED ALUMINUM AND AN OXIDANT CAN RE-
SULT IN A LOW-TEMPERATURE EXOTHERMIC REACTION AT 705 C IN THE PRESENCE
OF MOISTURE. INTERACTION OF MOLTEN SODIUM NITRATE AND
MAGNESIUM RESULTS IN IGNITION. MIXING SODIUM NITRATE WITH SODIUM
RESULTS IN THE FORMATION OF THE EXPLOSIVE SODIUM NITROXYLATE. A
MIXTURE OF SODIUM NITRATE, ARSENIC TRIOXIDE, IRON (II) SULFATE
SPONTANEOUSLY IGNITES. SODIUM NITRATE IN CONTACT WITH JUTE, WOOD AND
CELLULOSE MATERIALS WILL IGNITE THEM AT 240 C BUT IN THE PRESENCE OF
UP TO 16% MAGNESIUM CHLORIDE IGNITION OCCURS AT 130 C. HEATING SODIUM
NITRATE WITH: SODIUM PHOSPHINATE, SODIUM THIOSULFATE, SULFAMATES,
POWDERED ANTIMONY, BORON PHOSPHIDE, POWDERED CHARCOAL, PEROXYFORMIC
ACID, BARIUM THIOCYANATE, METAL CYANIDES RESULTS IN EXPLOSIONS. WHEN
PHENOL WAS ADDED TO TRIFLUOROACETIC ACID/SODIUM NITRATE, A HAZARDOUS
RAPID EXOTHERMIC REACTION OCCURRED.
SECTION 8. - - - - - - EXPOSURE CONTROLS/PERSONAL PROTECTION- - - - - -
WEAR APPROPRIATE NIOSH/MSHA-APPROVED RESPIRATOR, CHEMICAL-RESISTANT
GLOVES, SAFETY GOGGLES, OTHER PROTECTIVE CLOTHING.
USE ONLY IN A CHEMICAL FUME HOOD.
SAFETY SHOWER AND EYE BATH.
AVOID BREATHING DUST.
DO NOT GET IN EYES, ON SKIN, ON CLOTHING.
AVOID PROLONGED OR REPEATED EXPOSURE.
WASH THOROUGHLY AFTER HANDLING.
KEEP TIGHTLY CLOSED.
KEEP AWAY FROM COMBUSTIBLE MATERIALS, HEAT, SPARKS, AND OPEN FLAME.
STORE IN A COOL DRY PLACE.
