**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed.Air sensitive.
Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis. May cause
permanent corneal opacification.
Skin:
Causes skin irritation. May be absorbed through the skin.
Ingestion:
Ingestion of large amounts may cause gastrointestinal irritation.
May cause vascular collapse and damage. May cause methemoglobinemia,
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), convulsions, and death. May be harmful if swallowed.
Inhalation:
Harmful if inhaled. May cause methemoglobinemia, cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood),
convulsions, tachycardia, dyspnea (labored breathing), and death.
May cause acute pulmonary edema, asphyxia, chemical pneumonitis, and
upper airway obstruction caused by edema.
Chronic:
May cause reproductive and fetal effects. Laboratory experiments
have resulted in mutagenic effects. Animal studies have reported the
development of tumors. Sodium nitrate may react with secondary or
tertiary amines to form nitrosamines (certain nitrosamines are
cancer suspect agents).
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician:
Absorption of this product into the body may cause cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive
measures: bed rest and oxygen inhalation. For methemoglobinemia,
administer oxygen alone or with Methylene Blue depending on the
methemoglobin concentration in the blood. Cleansing of the entire
contaminated area of the body is of utmost importance. If cyanosis
is severe, intravenous injection of Methylene Blue, 1mg/kg of body
weight may be of value.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool.
Extinguishing Media:
Use water only! Cool containers with flooding quantities of water
until well after fire is out. For large fires, flood fire area with
water from a distance. Do NOT use dry chemicals, CO2, Halon or
foams.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Absorb spill using
an absorbent, non-combustible material such as earth, sand, or
vermiculite. Do not use combustible materials such as sawdust.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Keep container tightly closed. Do not ingest or inhale.
Storage:
Keep away from heat, sparks, and flame. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits

Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
