Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
Exposure to human tissue will result in irritation and subsequent chemical
burns, bronchitis, pulmonary edema and chemical pneumonitus.
INHALATION
Respiratory and mucous membrane irritation, coughing, difficulty breathing.
EYE CONTACT
Corrosive, causes eye burns.
SKIN CONTACT
Causes skin irritation. Prolonged contact may cause skin burns.
INGESTION
Burns on mouth and lips, sour acrid taste, severe gastrointestinal
irritation, nausea, vomiting, bloody diarrhea, difficult swallowing, severe
abdominal pains, thirst, acidemia, difficult breathing, convulsions, collapse,
shock, possible death.
SUMMARY OF CHRONIC HAZARDS
Bronchitis, pulmonary edema and chemical burns, bronchitis and chemical
pneumonitus; possible death.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Skin disorders, eye problems, impaired liver and kidney, or
respiratory function.
=============================================================================
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: Immediately flush with large amounts of water; use soap if
available. Remove contaminated clothing.
If in EYES: Immediately flush eyes with gentle but large stream of
water for at least 15 minutes, lifting lower and upper
eyelids
occasionally. Call a physician immediately.
If SWALLOWED: If swallowed, call a physician immediately. Only induce
vomiting at the instruction of a physician. Never give
anything by mouth to an unconscious person.

FLASH POINT LEL UEL
None N/A N/A
EXTINGUSING MEDIA
Use agents appropriate for surrounding fires.
SPECIAL FIRE FIGHTING PROCEDURES: Wear self-contained breathing apparatus
(SCBA) and other protective clothing. Hazardous decomposition products
possible (see Section 10). Evacuate immediate area.
UNUSUAL FIRE AND EXPLOSION HAZARDS: May release sulfur dioxide (SO2), sulfur
trioxide (SO3), and ammonia gas (NH3) if involved in a fire.
=============================================================================
Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Sweep up spillage
and flush the area with large quantities of water. May be neutralized with
sodium bicarbonate mixed with water.
=============================================================================
Section 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING: Prevent from absorption of
moisture and possible caking. Should be stored in a cool and dry place. Do not
store with cyanides, sulfides, chlorine, hypochlorous acid, or hypochlorites.
OTHER PRECAUTIONS: Refrain from splashing product when pouring. Avoid all
contact with skin or clothing. Empty containers may contain residues and
vapors. KEEP OUT OF REACH OF CHILDREN.
=============================================================================
Section 8 -- EXPOSURE CONTROLS/PERSONAL PROTECTION
-----------------------------------------------------------------------------
RESPIRATORY PROTECTION (SPECIFY TYPE): In confined poorly ventilated areas,
use NIOSH/MSHA approved air purifying or supplied air purifying or supplied
air respirators.
VENTILATION - LOCAL EXHAUST: Acceptable
SPECIAL: N/A
MECHANICAL (GENERAL): Acceptable
OTHER: N/A
PROTECTIVE GLOVES: Wear acid resistant gloves (neoprene, PVC, butyl rubber).
EYE PROTECTION: Full-face shield and chemical splash goggles (ANSI Z-87.1 or
equivalent).
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Acid resistant vinyl or polyethylene
coated coveralls.
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.

=============================================================================
Section 10 -- STABILITY AND REACTIVITY
-----------------------------------------------------------------------------
STABILITY: Stable
CONDITIONS TO AVOID: Incompatables
INCOMPATIBILITY (MATERIALS TO AVOID): Hazardous reaction in aqueous solution
may occur with chlorine, hypochlorous acid, hypochlorites, cyanides, nitric
acid, or sulfides. An explosion occurred when chlorine was being passed at
room temperature into a reaction mixture which included sulfamic acid and
water. Itis suspected that nitrogen trichloride, a very sensitive explosive,
was formed. Fuming nitric acid combined with sulfamic acid causes violent
releases of nitrous oxide.
HAZARDOUS DECOMPOSITION PRODUCTS: Decomposes with heat (209C) to release
sulfur dioxide (SO2), sulfur trioxide (SO3), nitrogen (N2), water (H2O), and
ammonia gas (NH3).
HAZARDOUS POLYMERIZATION: Will not occur.
