FIREFIGHTING
Protective Equipment: Wear self-contained breathing apparatus
and protective clothing to prevent contact with skin and eyes.
Specific Hazard(s): Emits toxic fumes under fire conditions.
Contact with other material may cause fire. May accelerate
combustion.
Section 6 - Accidental Release Measures
PROCEDURE TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Sweep up, place in a bag and hold for waste disposal. Avoid
raising dust. Ventilate area and wash spill site after material
pickup is complete.
Section 7 - Handling and Storage
HANDLING
User Exposure: Do not breathe dust. Do not get in eyes, on skin,
on clothing. Avoid prolonged or repeated exposure.
STORAGE
Suitable: Keep tightly closed. Keep away from combustible
materials, heat, sparks, and open flame.
Section 8 - Exposure Controls / PPE
ENGINEERING CONTROLS
Use only in a chemical fume hood. Safety shower and eye bath.
SIAL - S8170 www.wpiinc.com Page 2
PERSONAL PROTECTIVE EQUIPMENT
Respiratory: Use respirators and components tested and approved
under appropriate government standards such as NIOSH (US) or CEN
(EU). Where risk assessment shows air-purifying respirators are
appropriate use a full-face particle respirator type N100 (US) or
type P3 (EN 143) respirator cartridges as a backup to engineering
controls. If the respirator is the sole means of protection, use a
full-face supplied air respirator.
Hand: Compatible chemical-resistant gloves.
Eye: Chemical safety goggles.
GENERAL HYGIENE MEASURES
Wash thoroughly after handling. Remove and wash contaminated
clothing promptly. Discard contaminated shoes.

Section 10 - Stability and Reactivity
STABILITY
Stable: Stable.
Conditions to Avoid: Mixtures of sodium nitrate with powdered
aluminum and an oxidant can result in a low-temperature exothermic
reaction at 705掳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
SIAL - S8170 www.wpiinc.com Page 3
trioxide, iron (II) sulfate spontaneously ignites. Sodium nitrate
in contact with jute, wood and cellulose materials will ignite
them at 240掳C but in the presence of up to 16% magnesium chloride
ignition occurs at 130掳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
Materials to Avoid: Strong reducing agents, Finely powdered
metals, Strong acids, Organic materials.
HAZARDOUS DECOMPOSITION PRODUCTS
Hazardous Decomposition Products: Nitrogen oxides.
HAZARDOUS POLYMERIZATION
Hazardous Polymerization: Will not occur
