**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns.Corrosive.Hygroscopic (absorbs moisture from the
air).
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
Causes skin burns. Continued contact can cause tissue necrosis. May
cause skin rash (in milder cases), and cold and clammy skin with
cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause systemic toxicity with
acidosis.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary 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.
Chronic inhalation or ingestion of silver salts may cause argyria
characterized by a permanent blue-gray discoloration of the eyes,
skin, mucous membranes, and internal organs. This malady results
from the accumulation of silver in the body. 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 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:
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. Combustion generates toxic fumes. Strong oxidizer.
Contact with other material may cause fire. 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. For small fires, use water spray,
dry chemical, carbon dioxide or chemical foam. 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. Do not store in direct
sunlight. Keep container closed when not in use. Keep from contact
with oxidizing materials. 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 adequate
ventilation to keep airborne concentrations low. Use only under a
chemical fume hood.
