**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Toxic if swallowed. Causes burns. May cause cancer. Very toxic to
aquatic organisms, may cause long-term adverse effects in the
aquatic environment.

Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May cause deep, penetrating ulcers of the skin.
May cause skin rash (in milder cases), and cold and clammy skin with
cyanosis or pale color. Concentrated nitric acid dyes human skin
yellow on contact.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May cause systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects.
Chronic:
Arsenic trioxide can cause cancer in humans. Other long term effects
include: anemia, liver and kidney damage. Exposure to high
concentrations of nitric acid vapor may cause pneuomonitis and
pulmonary edema which may be fatal. Symptoms may or may not be
delayed. Continued exposure to the vapor & mist of nitric acid may
result in a chronic bronchitis, & more severe exposure results in a
chemical pneumonitis. The vapor & mists of nitric acid may erode the
teeth, particularly affecting the canines & incisors. Inorganic
arsenic compounds may cause skin and lung cancers in humans.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. 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:

**** 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. May react with metal
surfaces to form flammable and explosive hydrogen gas. Approach fire
from upwind to avoid hazardous vapors and toxic decomposition
products. Concentrated nitric acid is a strong oxidizer and contact
with other material may cause fire.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill using an absorbent, non-combustible material such as
earth, sand, or vermiculite. Do not use combustible materials such
as sawdust. Provide ventilation. Approach spill from upwind.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not get in eyes,
on skin, or on clothing. Keep container tightly closed. Do not ingest
or inhale. Discard contaminated shoes. Do not use with metal spatula
or other metal items.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from metals. Store away from alkalies.

**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits. See 29CFR 1910.1018 for regulatory
requirements pertaining to all occupational exposures to inorganic
arsenic.
