           Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   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.	
EYE CONTACT
   Causes irritation, redness, and pain.	
SKIN CONTACT
   Causes skin irritation. Prolonged contact may cause skin burns.	
INGESTION
   Toxic. Can irritate the mouth, esophagus, stomach, etc. Excessive amounts
affect the blood and blood vessels. Signs and symptoms of nitrite poisoning
include intense cyanosis, nausea, dizziness, vomiting, collapse, spasms of
abdominal pain, rapid heart beat, irregular breathing, coma, convulsions, and
death due to circulatory collapse. Estimated lethal dose 1 to 2 grams.
SUMMARY OF CHRONIC HAZARDS
   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. 
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
   Individuals with pre-existing or chronic diseases of the eyes, skin and
   respiratory system may have increased susceptibility to excessive exposure.
=============================================================================
           Section 4 -- FIRST AID MEASURES
-----------------------------------------------------------------------------
   If INHALED:     If overcome by exposure, remove victim to fresh air 
                   immediately.  Give oxygen or artificial respiration as 
                   needed.  Obtain emergency medical attention.  Prompt action 
                   is essential.
   If on SKIN:     Wash with soap and water.  If irritation occurs, seek 
                   medical attention.
   If in EYES:     Immediately flush eyes with plenty of water for at least 15 
                   minutes, lifting upper and lower eyelids occasionally. Get
                   medical attention if irritation persists.
                   occasionally. Call a physician immediately. 
   If SWALLOWED:   If swallowed, call a physician or poison control   
                   immediately. Only induce vomiting at the instruction of 
                   a physician. Never give anything by mouth to an unconscious 
                   person.

   Note: Not combustible, but substance is a strong oxidizer and its heat of
   reaction with reducing agents or combustibles may cause ignition. Increases
   the flammability of any combustible material.
EXTINGUSING MEDIA
   Water or water spray in early stages of fire. Foam may also be used, but 
avoid the use of multi-purpose dry chemical fire extinguishers where contact 
with sodium nitrite may occur. Water streams may scatter molten material. 
SPECIAL FIRE FIGHTING PROCEDURES:  In the event of a fire, wear full protective 
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode.
Decomposition of potassium nitrite may leave a caustic residue. 
UNUSUAL FIRE AND EXPLOSION HAZARDS:  Contact with oxidizable substances may 
cause extremely violent combustion. May explode when heated to 537 C (1000 F) 
or on severe impact or on contact with cyanides, ammonium salts, cellulose, 
lithium, potassium plus ammonia, and sodium thiosulfate. 		

=============================================================================
           Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:  Remove all
sources of ignition. Wear appropriate personal protective equipment as
specified in Section 8.  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 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING:  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. 
OTHER PRECAUTIONS: Avoid prolonged or repeated contact with skin or clothing.
KEEP OUT OF REACH OF CHILDREN.
=============================================================================
           Section 8 -- EXPOSURE CONTROLS/PERSONAL PROTECTION
-----------------------------------------------------------------------------
RESPIRATORY PROTECTION (SPECIFY TYPE):  Normally none required. Use NIOSH/MSHA
approved particulate respirator for nuisance dust.
VENTILATION - LOCAL EXHAUST:  Acceptable
SPECIAL:  N/A
MECHANICAL (GENERAL):  Acceptable
OTHER:  N/A
PROTECTIVE GLOVES:  Natural rubber latex.
EYE PROTECTION:  Safety glasses (ANSI Z-87.1 or equivalent).  
OTHER PROTECTIVE CLOTHING OR EQUIPMENT:  Coveralls recommended. 
WORK/HYGIENIC PRACTICES:  Where use can result in skin contact, wash exposed
areas thoroughly before eating, drinking, smoking, or leaving work area. 
Launder contaminated clothing before reuse.
