Composition, Information on Ingredients
Risk Phrases: 34
Section 3 - Hazards
Appearance: colorless to slight yellow. Danger! Corrosive.
Causes eye and skin burns. May cause severe respiratory tract irritation with
possible burns. May cause severe digestive tract irritation with possible burns.
May cause fetal effects based upon animal studies. Possible sensitizer. May be
harmful if swallowed. Hygroscopic.
Target Organs: Teeth,
Eye: May cause irreversible eye
injury. Vapor or mist may cause irritation and severe burns. Contact with liquid
is corrosive to the eyes and causes severe burns. May cause painful
sensitization to light.
Skin: May be absorbed through the
skin in harmful amounts. May cause skin sensitization, an allergic reaction,
which becomes evident upon re-exposure to this material. Contact with liquid is
corrosive and causes severe burns and ulceration.
Ingestion: May cause circulatory system failure. Causes
severe digestive tract burns with abdominal pain, vomiting, and possible death.
May cause corrosion and permanent tissue destruction of the esophagus and
digestive tract. May be harmful if swallowed.
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. Exposure to the mist and vapor may erode exposed teeth.
Causes corrosive action on the mucous membranes.
Prolonged or repeated skin contact may cause dermatitis. Repeated exposure may
cause erosion of teeth. May cause fetal effects. Laboratory experiments have
resulted in mutagenic effects. Prolonged exposure may cause conjunctivitis,
photosensitization, and possible blindness.
Section 4 - First Aid
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). SPEEDY ACTION IS CRITICAL!
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
Notes to Physician: Do NOT use sodium bicarbonate in
an attempt to neutralize the acid.
Antidote: Do NOT use
oils or ointments in eye.
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. Water runoff can cause environmental damage. Dike and collect water used
to fight fire. During a fire, irritating and highly toxic gases may be generated
by thermal decomposition or combustion. Not flammable, but reacts with most
metals to form flammable hydrogen gas. Use water spray to keep fire-exposed
containers cool. Vapors may be heavier than air. They can spread along the
ground and collect in low or confined areas. Reaction with water may generate
much heat which will increase the concentration of fumes in the air. Containers
may explode when heated.
Extinguishing Media: For large
fires, use water spray, fog, or alcohol-resistant foam. Substance is
noncombustible; use agent most appropriate to extinguish surrounding fire. Do
NOT get water inside containers. Do NOT use straight streams of water. Most
foams will react with the material and release corrosive/toxic gases. Cool
containers with flooding quantities of water until well after fire is out. For
small fires, use carbon dioxide (except for cyanides), dry chemical, dry sand,
and alcohol-resistant foam.
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
Spills/Leaks: Large spills may be neutralized
with dilute alkaline solutions of soda ash, or lime. Avoid runoff into storm
sewers and ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all sources of
ignition. Provide ventilation. Do not get water inside containers. A vapor
suppressing foam may be used to reduce vapors. Cover with dry earth, dry sand,
or other non-combustible material followed with plastic sheet to minimize
spreading and contact with water.
Section 7 - Handling
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Use only in a well-ventilated area.
Contents may develop pressure upon prolonged storage. Do not breathe dust,
vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Do not ingest or inhale. Discard contaminated shoes. Use caution
when opening. Keep from contact with moist air and steam.
Storage: Do not store in direct sunlight. Store in a
tightly closed container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Corrosives area. Do not store in metal containers.
Store protected from moisture. Do not store near flammable or oxidizing
substances (especially nitric acid or chlorates).
