  • Sulfuric acid is the largest-volume industrial chemical produced in the
    world and is the most commonly used as a strong acid.
  • Sulfuric acid is used in:
    -Metal processing and refining.
    -Electroplating baths.
    -Water treatment, to adjust pH and to control corrosion and scaling.
    -Petroleum refining (alkylation) of high-quality, high-octane gasoline
    -Pickling (cleaning) iron and steel before plating with tin or zinc.
  • Sulfuric acid is also used as a drying agent to chemically remove water
    from many compounds, such as wood, cotton, sugar, and paper.
  • Sulfuric acid is used in the production of:

   Safety & First aid

Inhalation produces damaging effects on the mucous membranes and upper
respiratory tract. Symptoms may include irritation of the nose and throat,
and labored breathing. May cause lung edema, a medical emergency.

Corrosive. Swallowing can cause severe burns of the mouth, throat, and stomach, leading to death. Can cause sore throat, vomiting, diarrhea. Circulatory collapse with clammy skin, weak and rapid pulse, shallow respirations, and scanty urine may follow ingestion or skin contact.

Skin Contact:
Corrosive. Symptoms of redness, pain, and severe burn can occur. Circulatory
collapse with clammy skin, weak and rapid pulse, shallow respirations,
and scanty urine may follow skin contact or ingestion.

Eye Contact:
Corrosive. Contact can cause blurred vision, redness, pain and severe tissue burns. Can cause blindness.

Chronic Exposure:
Long-term exposure to mist or vapors may cause damage to teeth.
Chronic exposure to mists containing sulfuric acid is a cancer hazard.

Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired
respiratory function may be more susceptible to the effects of the substance.


First Aid

Remove to fresh air. If not breathing, give artificial respiration. If breathing
is difficult, give oxygen. Call a physician immediately.

DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Call a physician immediately.

Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least
15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Excess acid on skin can be neutralized with a 2% solution of bicarbonate of soda. Call a physician immediately.

Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Call a physician immediately.

Fire Fighting Measures

Concentrated material is a strong dehydrating agent. Reacts with organic materials and may cause ignition of finely divided materials on contact.

Contact with most metals causes formation of flammable and explosive
hydrogen gas.

Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Do not use water on material. However,
water spray may be used to keep fire exposed containers cool.

Special Information:
In the event of a fire, wear full protective clothing and self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. Structural firefighter’s protective clothing is ineffective for fires involving this material. Stay away from sealed containers.


    Special Features

Stable under ordinary conditions of use and storage. Concentrated solutions react violently with water, spattering and liberating heat.

Hazardous Decomposition Products:
Toxic fumes of oxides of sulfur when heated to decomposition.
Will react with water or steam to produce toxic and corrosive fumes.
It reacts with carbonates to generate carbon dioxide gas, and with cyanides and sulfides to form poisonous hydrogen cyanide and hydrogen
sulfide respectively.

Hazardous Polymerization:
Will not occur.

Water, potassium chlorate, potassium perchlorate,
potassium permanganate, sodium, lithium, bases,
organic material, halogens, metal acetylides, oxides and hydrides, metals
(yields hydrogen gas), strong oxidizing and reducing agents and many other reactive substances.

Conditions to Avoid:
Avoid exposure to heat, moisture, incompatibles.
