SECTION II - HAZARD IDENTIFICATION
Emergency Overview: DANGER! STRONG OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE.
HARMFUL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN. CAUSES
IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT.
Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath.
Ingestion: Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and
diarrhea. May cause gastroenteritis and abdominal pains. Purging and diuresis can be
expected. Rare cases of nitrates being converted to the more toxic nitrites have been reported,
mostly with infants.
Skin: Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact: Causes irritation, redness, and pain.
Chronic Exposure: Under some circumstances methemoglobinemia occurs in individuals when the nitrate is
converted by bacteria in the stomach to nitrite. Nausea, vomiting, dizziness, rapid heart beat,
irregular breathing, convulsions, coma, and death can occur should this conversion take place.
Chronic exposure to nitrites may cause anemia and adverse effects to kidney.
Aggravated by Exposure: No Information Found.
SECTION III - COMPOSITION / INFORMATION ON INGREDIENTS
CAS #: CHEMICAL NAME
7757-79-1 Potassium Nitrate 100%
SECTION IV - FIRST AID MEASURES
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to
an unconscious person. Get medical attention.
Skin: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes
before reuse.
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.
SECTION V - FIRE FIGHTING MEASURES
Fire: Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents
or combustibles may cause ignition.
Explosion: Some nitrates may explode when shocked, exposed to heat or flame, or by spontaneous
chemical reaction. Sealed containers may rupture when heated. Sensitive to mechanical impact.
Fire Extinguishing Media: Dry chemical, carbon dioxide, Halon, water spray, or fog. If water is used, apply from as far a
distance as possible. Water spray may be used to keep fire exposed containers cool. Do not
allow water runoff to enter sewers or waterways.
Wear full protective clothing and breathing equipment for high-intensity fire or potential explosion
Special Information:
conditions. This oxidizing material can increase the flammability of adjacent combustible
materials.
SECTION VI - ACCIDENTAL RELEASE MEASURES
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not

disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and
prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a
closed container.
SECTION VII - HANDLING AND STORAGE
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical
damage and moisture. Isolate from any source of heat or ignition. Avoid storage on wood floors.
Separate from incompatibles, combustibles, organic or other readily oxidizable materials.
Containers of this material may be hazardous when empty since they retain product residues
(dust, solids); observe all warnings and precautions listed for the product.
SECTION VIII - EXPOSURE CONTROL / PERSONAL PROTECTION
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low
as possible. Local exhaust ventilation is generally preferred because it can control the emissions
of the contaminant at its source, preventing dispersion of it into the general work area.
Airborne Exposure Limits: None Established.
Personal Respirators: For conditions of use where exposure to dust or mist is apparent and engineering controls are
(NIOSH APPROVED) not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P
filter. For emergencies or instances where the exposure levels are not known, use a full-face
positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect
workers in oxygen-deficient atmospheres.
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as
