Emergency Overview
This product is a clear, colorless liquid. This product is an oxidizer. This product is irritating to the eyes and skin.
Inhalation of mists or sprays of this product has potential for moderate irritation of mucous membranes. This
product may react with combustible materials to cause ignition.
Potential Health Effects: Eyes
Contact with the eyes can cause moderate irritation. Symptoms may include discomfort or pain and redness.
Severe overexposure can result in swelling of the conjunctiva along with tissue damage.
Potential Health Effects: Skin
This product is moderately irritating to the skin and other contaminated tissue. Depending on the duration of
contact, symptoms will include reddening, discomfort, irritation, and possible tissue damage. Prolonged and/or
repeated skin contact with this product may cause irritation/dermatitis. No components in this product are known
to be absorbed through the skin.
Potential Health Effects: Ingestion
Ingestion of this product can be harmful or fatal. Immediately upon contact, this product will cause irritation and
burns of the mouth, throat, esophagus, and other tissues of the digestive system. Overexposure symptoms
include: nausea, abdominal pain, vomiting, and diarrhea. Severe ingestion overexposures can result in
convulsions and collapse. The nitrate component of this product may damage the oxygen transport system of the
blood. Severe ingestion exposures can be fatal. Repeated ingestion of small amounts of this product may cause
weakness, depression, headaches, and mental impairment.
Potential Health Effects: Inhalation
Inhalation of vapors, mists, or sprays of this product may irritate the nose, throat, and lungs. Symptoms may
include: sneezing, coughing and difficulty breathing. Most symptoms are alleviated, when the overexposure ends.
HMIS Ratings: Health: 2 Fire: 0 Physical Hazard: 0

General Fire Hazards
This product is an aqueous mixture, which will not burn. If evaporated to dryness, the solid residue may pose a
slight fire hazard. This product is an oxidizing agent, which may cause spontaneous ignition of combustible
materials.
Hazardous Combustion Products
Decomposition of this product may produce acrid vapors, sodium compounds, and oxides of nitrogen.
Extinguishing Media
Use any media suitable for the surrounding fires.
Fire Fighting Equipment/Instructions
Fire fighters should wear full-face, self-contained breathing apparatus and impervious protective clothing. Fire
fighters should avoid inhaling any combustion products.
NFPA Ratings: Health: 2 Fire: 0 Reactivity: 0

* * * Section 6 - Accidental Release Measures * * *
Containment Procedures
Stop the flow of material, if this is without risk. Wear appropriate protective equipment and clothing during clean
up. Contain the discharged material and dike the spilled material where possible. Prevent entry into sewers,
drains, underground or confined spaces, water intakes and waterways. Avoid contact with combustible materials.
Clean-Up Procedures
Absorb spill with inert material. Shovel material into appropriate container for disposal.
Evacuation Procedures
Isolate area. Keep unnecessary personnel away.
Special Procedures
Follow all Local, State, Federal and Provincial regulations for disposal.

* * * Section 7 - Handling and Storage * * *
Handling Procedures
Do not get this material in your eyes, on your skin, or on your clothing. Avoid breathing vapors or mists of this
product. Wash thoroughly after handling. Do not eat, drink or use tobacco products when handling this material.
Use this product with adequate ventilation. Launder work clothes frequently. See Section 8 for appropriate
protective clothing, equipment and air monitoring procedures.
Open containers slowly, on a stable surface. Containers of this product must be properly labeled. Empty
containers may contain residual liquid or vapors. Empty containers should be handled with care.
Storage Procedures
Store containers in a cool, dry location, away from direct sunlight, sources of intense heat, or where freezing is
possible. Store away from incompatible materials (see SECTION 10: Stability and Reactivity). Material should be
stored in secondary containers, or in a diked area, as appropriate. Keep container tightly closed when not in use.
Inspect all incoming containers before storage, to ensure containers are properly labeled and not damaged.
