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

EMERGENCY OVERVIEW
Causes severe burns.Corrosive.Hygroscopic.

Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
Causes skin burns. Continued contact can cause tissue necrosis.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause systemic toxicity with
acidosis.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract. Inhalation may be fatal as
a result of spasm, inflammation, edema of the larynx and bronchi,
chemical pneumonitis and pulmonary edema. Causes corrosive action on
the mucous membranes.
Chronic:
Prolonged or repeated inhalation may cause kidney and lung damage.
Prolonged or repeated skin contact may cause dermatitis. Prolonged or
repeated inhalation may cause nosebleeds, nasal congestion, erosion
of the teeth, perforation of the nasal septum, chest pain and
bronchitis. Prolonged or repeated eye contact may cause
conjunctivitis. May cause fetal effects. May cause cancer in humans.
Laboratory experiments have resulted in mutagenic effects. May cause
ischemic heart lesions.

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

Eyes:
Get medical aid immediately. Do NOT allow victim to rub 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
soap and 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 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:
Monitor arterial blood gases, chest x-ray, and pulmonary function
tests if respiratory tract irritation or respiratory depression is
evident. Treat dermal irritation or burns with standard topical
therapy. Effects may be delayed. Do NOT use sodium bicarbonate in an
attempt to neutralize the acid.
Antidote:
Do NOT use oils or ointments in eye.

**** 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. Wear appropriate protective clothing to prevent
contact with skin and eyes. Wear a self-contained breathing apparatus
(SCBA) to prevent contact with thermal decomposition products. Will
react with water to form toxic and corrosive fumes. Contact with
water can cause violent liberation of heat and splattering of the
material. Contact with metals may evolve flammable hydrogen gas.
Containers may explode when heated or if contaminated with water.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Use carbon dioxide or dry chemical. Do NOT
get water inside containers. Cool containers with flooding quantities
of water until well after fire is out. For large fires, flood fire
area with large quantities of water, while knocking down vapors with
water fog.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Provide ventilation. Use water spray to reduce
vapors, do not put water directly on leak, spill area or inside
container. Cover with dry earth, dry sand, or other non-combustible
material followed with plastic sheet to minimize spreading and
contact with water. Keep combustibles (wood, paper, oil, etc.,) away
from spilled material.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Keep
container tightly closed. Do not ingest or inhale. Do not allow
contact with water. Use only in a chemical fume hood. Discard
contaminated shoes. Keep from contact with moist air and steam.
Storage:
Do not store near combustible materials. Keep container closed when
not in use. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from water. Corrosives area. Do
not store near alkaline substances. Store protected from moisture.

**** 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 only under a
chemical fume hood.
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 a respirator's use.
