Hazards
Identification

POISON ! DANGER! CORROSIVE.Liquid and mist cause severe burns to all body tissue. May be fatal if swallowed or contacted with skin. Harmful, if inhaled, water reactive.

Potential
Health Effects

  • Ingestion Corrosive, swallowing can cause severe burns of the mouth, throat and stomach.
  • Skin Contact Corrosive, symptoms of redness, paid and severe burn can occur.
  • Eye Contact Corrosive, contact can cause blurred vision, redness, pain and severe tissue burns.Can cause blindness.

First Aid

  • If the substance has got into eyes, immediately wash with plenty of water for at least 15 minutes.
  • Seek medical treatment.Keep patient at rest.
  • In case of skin contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.

Fire Fighting

  • Cannot catch fire
  • Contact with combustibles may cause fire
  • Explosive concentrations of hydrogen gas can accumulate inside metal tanks containing acid.
  • Care must be taken not to ignite hydrogen gas which may accumulate inside tank.

Fire Extinguishing
Media

Fires involving small amounts of combustible ignite by contact with Sulphuric Acid may be smothered by dry chemical, foam or carbon dioxide.

Accident Release
Measures

Ventilate area of leak or spill.Wear appropriate personal protective equipment. Isolate hazard area.Keep unnecessary and unprotected personnel form entering. Contain and recover liquid when possible. Neutralize with alkaline material (Soda Ash,lime), then absorb with an inert material (e.g. dry sand, earth) and place in a chemical waste container. Do not use combustible materials such as saw dust. Do not flush to sewer.

Handling and
Storage

  • Concentrated Sulphuric Acid can be stored in mild steel tanks.
  • Lead lined tanks are recommended for Sulphuric Acid upto 80% strength.
  • Smaller quantities of Sulphuric Acid are stored in metal drums, plastic jerrycans, glass carboys or bottles.
  • Store in a cool, dry, ventilated storage area with acid resistant floors and good drainage, protect from physical damage. Do not wash out container and use for other purposes when diluting, always add acid to water, never add water to acid. When opening metal
  • Containers: use non sparking tools because of possibility of hydrogen gas being present. Containers of this material may be hazardous when empty since they retain product residues (vapour, liquid); observe all warnings and precautions listed for the product.

Protective
Clothing

Workers employed in handling Sulphuric should wear suitable Acid proof personal protective equipment, including chemical clear goggles, face shield, PVC/ rubber hand gloves, neoprene PVC boots, acid resistant trousers, the legs of which should fall over the boots and be tucked into them.

Stability and
Reactivity

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

Hazardous
Polymerisation

Will not occur

Conditions to
Avoid

Heat, moisture, incompatibles

Incompatibilities

Water, potassium chlorate, potassium perchlorate, potassium permanganate, sodium, lithium basis, organic material, halogens, metal acetylides, oxides and hydrides, metals, strong oxidizing and reducing agents and many other reactive substances.

Disposal
Considerations

Whatever cannot be saved for recovery or recycling should be handled as hazardous waste and disposed off as per local regulations. Processing, use or contamination of this product may change the waste management options.

Transport
Information
