Section 3 - Hazards Identification

Appearance: colorless. Caution! Corrosive. May cause eye irritation and possible burns.
Target Organs: None known.


Potential Health Effects
Eye: May cause irritation, pain, blurred vision, possible burns, and conjunctivitis. Direct contact may cause corneal and episcleral damage.
Skin: Exposure of the skin to the liquid or concentrated vapor produces sever and penetrating burns. Penetration may continue for several days.
Ingestion: Ingestion will cause irritation to mucous membranes, gastrointestinal tract. Severe abdominal pain, coma and death are possible. Perforation of gastrointestinal tract can occur, even after several days.
Inhalation: Inhalation may cause sore throat, coughing, irritation to respiratory tract.
Chronic: Prolonged or repeated skin contact may cause dermatitis. Repeated or prolonged exposure may cause irritation to respiratory tract. Repeated or prolonged contact may cause conjunctivitis, corneal burns. Repeated ingestion may cause irritation and burning to gastrointestinal tract.

Section 4 - First Aid Measures

Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until no evidence of chemical remains. Get medical aid at once. Cover burns with loose sterile non-medicated bandages.
Skin: Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Remove contaminated clothing and shoes. Cover burns with a dry sterile bandage (secure, not tight).
Ingestion: Do NOT induce vomiting. Get medical aid at once. If victim is conscious, give 2-4 glasses of water to dilute alkali.
Inhalation: Give artificial respiration if necessary. Get medical aid. Keep victim warm, at rest. Move victim to fresh air.
Notes to Physician: Treat symptomatically.

Section 5 - Firefighting Measures

General Information: Negligible fire and explosion hazard when exposed to heat or flame. Move container if possible, cool with flooding amounts of water.
Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Neutralize spill with a weak acid such as vinegar or acetic acid. For soil spills, dig holding pit to contain spill and dike surface flow with barrier of soil, sandbags, or foamed concrete. Absorb liquid with fly ash or cement powder. For water spills, neutralize with dilute acid. For occupational spills, do not touch spilled material. Keep people away and isolate area. Stop leak if possible. Small spills can be absorbed with sand or other absorbent materials. Scoop up and place in suitable containers for proper disposal.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Avoid breathing dust, vapor, mist, or gas. Avoid contact with eyes, skin, and clothing.
Storage: Store at room temperature. Protect from heat and water reactive substance (sodium, oleum).

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Provide local exhaust or general dilution ventilation.
