**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury. May
cause permanent corneal opacification. The severity of injury
depends on the concentration of the solution and the duration of
exposure.
Skin:
Causes skin burns. The severity of injury depends on the
concentration of the solution and the duration of exposure.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns.
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. Because its vapor
pressure is negligible, it exists in the air only as a mist or spray.
Chronic:
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. Effects may be delayed. Workers chronically exposed
to sulfuric acid mists may show various lesions of the skin,
tracheobronchitis, stomatitis, conjunctivitis, or gastritis.
Occupational exposure to strong inorganic acid mists containing
sulfuric acid is carcinogenic to humans.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
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. Use water spray to keep fire-exposed containers
cool. Substance is noncombustible. Contact with water can cause
violent liberation of heat and splattering of the material. Contact
with metals may evolve flammable hydrogen gas. Runoff from fire
control or dilution water may cause pollution. Strong dehydrating
agent, which may cause ignition of finely divided materials on
contact. Oxides of sulfur may be produced in fire.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Do NOT get water inside containers. If water is used, care should be
taken, since it can generate heat and cause spattering if applied
directly to sulfuric acid.
**** 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. Carefully scoop up and place into appropriate
disposal container. Provide ventilation. Do not expose spill to
water. 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 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 allow contact with water. Discard
contaminated shoes. Use only with adequate ventilation. Do not
breathe spray or mist.
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 adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

Wear appropriate protective gloves to prevent skin
exposure.

Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
