**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Reacts violently with water. Very toxic by inhalation. Causes severe
burns.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
May be fatal if inhaled. May cause severe irritation of the
respiratory tract with sore throat, coughing, shortness of breath
and delayed lung edema. Exposure may impair lung function and cause
mucostasis (reduced mucous clearance).
Chronic:
Repeated exposure may cause erosion of teeth. Inhalation of product
may aggravate existing chronic repiratory problems such as asthma,
emphysema or bronchitis. 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:
Treat symptomatically and supportively. 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.
**** 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. Water Reactive. Material will react with water and
may release a flammable and/or toxic gas. Use water spray to keep
fire-exposed containers cool. Contact with water can cause violent
liberation of heat and splattering of the material. Containers may
explode when heated or if contaminated with water. Reacts with most
metals in the presence of moisture, liberating extremely flammable
hydrogen gas. Runoff from fire control or dilution water may cause
pollution. Approach fire from upwind to avoid hazardous vapors and
toxic decomposition products. Strong dehydrating agent, which may
cause ignition of finely divided materials on contact. Oxides of
sulfur may be produced in fire. SO3 chars many organic substances
due to its avidity for water. On contact with wood shavings, the
heat produced by dehydration is sufficient to cause fire.
Extinguishing Media:
Use dry sand or earth to smother fire. 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. 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.
Carefully scoop up and place into appropriate disposal container.
Provide ventilation. Do not get water inside containers. 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.
Evacuate unnecessary personnel. Approach spill from upwind.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not allow water to get into the container
because of violent reaction. 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. Discard contaminated shoes. Keep from
contact with moist air and steam. Store absolutely dry. Do not use
with metal spatula or other metal items. Inform laundry personnel of
contaminant's hazards. Use only with adequate ventilation or
respiratory protection.
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 in metal containers. Do not store near alkaline
substances. Store protected from moisture. Ideally, sulfuric acid
should be stored in isolation from all other chemicals in an
approved acid or corrosives safety cabinet.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. 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. Use a corrosion-resistant ventilation system.
