  Sulfuric acid safety Firstaid Acute symptoms Types of exposure Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. Corrosive. Burning sensation. Sore throat. Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed . •Inhalation Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. Corrosive. Redness. Pain. Blisters. Serious skin burns. •Skin First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. Corrosive. Redness. Pain. Severe deep burns. •Eyes Rinse mouth. Do NOT induce vomiting. Refer for medical attention. Corrosive. Abdominal pain. Burning sensation. Shock or collapse. •Ingestion IN ALL CASES CONSULT A DOCTOR!

  Sulfuric acid safety FIREFIGHTING ACUTE HAZARDS TYPES OF HAZARD NO water. In case of fire in the surroundings: powder, foam, carbon dioxide Not combustible. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. FIRE In case of fire: keep drums, etc., cool by spraying with water but NO direct contact with water. Risk of fire and explosion on contact with base(s) , combustible substances , oxidants , reducing agents or water . EXPLOSION

  Sulfuric acid safety Packaging& labeling Storage Spillage disposal Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs. Note: B C symbol R: 35 S: 1/2-26-30-45 UN Hazard Class: 8 UN Packing Group: II Separated from combustible and reducing substances, strong oxidants, strong bases, food and feedstuffs , incompatible materials . See Chemical Dangers. May be stored in stainless steel containers. Store in an area having corrosion resistant concrete floor. Keep container tightly closed. Keep container in a cool, well ventilated area. Stop leak if without risk. Absorb with inert material. Do not get water inside container. Do not touch spilled material. Use water spray curtain to divert vapor drift. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Neutralize the residue with a dilute solution of sodium carbonate.

  Attention  Concretes madeof cement are highly alkaline with pH values normally above 12.5 and are not easily attacked by acidic solutions. As the pH of the solution decreases the equilibrium in the cement matrix is being disturbed, and the hydrated cement compounds are essentially altered by hydrolytic decomposition which leads to the severe degradation.  Taking sample from sulfuric truck to detect the iron in sulfuric sample, Rust is an iron oxide, usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture.
