MATERIAL SAFETY DOCUMENT STANDARD (MSDS) Sulfuric Acid (H2SO4) Section 1. Product Information 1) TRADE NAME: Sulfuric Acid 2) COMMON NAME: Oil Of Vitriol, 3) HMIS RATING: Health Hazard-2 Fire Hazard-1 Reactivity Hazard-3 Specific Hazard-Use No Water 4) C.A.S. NUMBER: 7664-93-9 5) CHEMICAL FAMILY: Inorganic Acids Section 2. Ingredients 1) FORMULA: H2SO4 2) COMPOSITION: Sulfuric Acid (93.0 ~ 98.0 %) Water (2.0 %) Section 3. Hazard Identification 1) CLASSIFICATION: Corrosive ID No. 1830 2) EMERGENCY CONCERNS: None Established 3) PRECAUTIONARY MEASURE Avoid breathing mist or vapors. The International Agency for Research for Cancer ("IARC") Monographs on the Evaluation of Carcinogen risk to Humans at 106 (Vol. 54, 1992) lists strong inorganic acid mists containing sulfuric acid as a suspected carcinogen. The National Toxicology Program ("NTP") lists strong inorganic acid mists containing sulfuric acid as a known carcinogen in the 9th Report on Carcinogens (9th RoC, May 15, 2000). This applies to inorganic acid mists containing sulfuric acid and does not apply to sulfuric acid or sulfuric acid solutions. Avoid Ingestion Avoid Contact with eyes or skin Wash thoroughly after handling Use in adequate ventilation 4) OVEREXPOSURE CONDITIONS: Acute: Contact with the body results in rapid destruction of tissue, causing severe burns. Mist or vapor also causes severe irritation to the lungs, nose and throat. If swallowed, it can cause severe damage to the throat and stomach. Chronic: Repeated contact with dilute solutions can cause dermatitis and prolonged exposure to vapor mist can cause inflammation of the upper respiratory tract leading to chronic bronchitis. Erosion of the teeth may also occur upon exposure. Pre-existing respiratory diseases, including asthma and emphysema, skin disorders and eye problems may also be aggravated. Section 4. First Aid Measures 1) IMMEDIATE TREATMENT: If in eyes: Immediately flush with plenty of water for at least 15 minutes. Get medical attention immediately. If on skin: Immediately flush with plenty of water. Remove contaminated clothing. Discard contaminated clothing properly. If inhaled: Move to fresh air. Treat symptomatically. Get medical attention promptly. If ingested: Give large quantities of water to patient if conscious. Do Not induce vomiting. Seek medical attention as soon as possible. 2) FIRST AID TREATMENT: Same as above 3) A NOTE TO PHYSICIAN: Not applicable Section 5. Fire Fighting Measures 1) FLASH POINT: Not applicable. 2) FIRE FIGHTING HAZARDS: It is a strong oxidant and in contact with some organic materials may cause fires and explosions. Will react with water or steam. May generate hydrogen gas when in contact with some metals. 3) APPROPRIATE EXTINGUISHING MEDIA: Small fires: Water spray, dry chemical or CO2 Large fires: Water spray, dry chemical or CO2 4) SPECIFIC PROTECTIVE EQUIPMENT: Wear self-contained breathing apparatus with full protective clothing. Section 6. Accidental Release Measures 1) CONTROLLING SPILLS: Small spills: Contain spill and stop leak if it can be done without risk. use sand or noncumbistible absorbent material to soak up material. Place in container and dispose of properly. Large spills: Use same procedure as above. Prevent discharge into waterways and sewers. Material may be neutralized with sodium carbonate or a mixture of soda ash and slaked lime. Sulfuric Acid and soda ash or lime reacts vigorously. Add slowly and be careful of spattering. Contact proper local, state, or federal regulatory agency (ies) to ascertain proper disposal techniques and procedures. 2) PPE: Respiratory Protection: Use full-face respirator, certified for acid, acid mist or vapor if TLV is exceeded. Skin Protection: Acid proof gloves, head gear, and clothing should be worn to prevent contact. Eye Protection: Splash proof goggles and full face shield should be worn at all times. 3) ENGINEERING CONTROLS: Eye wash and shower stations should be available in areas where acid is being handled. Section 7. Handling And Storage 1) STORAGE CONDITIONS: None established. 2) HANDLING PROCEDURES: Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling. Maintain proper hygiene practices when handling this product. Section 8. Exposure Controls/PPE 1) EXPOSURE LIMITS: OSHA Permissible Exposure Limits (PEL): 1 mg/m3 ACGIH Threshold Limit Value (TLV): 1 mg/m3 2) PPE: Respiratory Protection: Use full-face respirator, certified for acid, acid mist or vapor if TLV is exceeded. Skin Protection: Acid proof gloves, head gear, and clothing should be worn to prevent contact. Eye Protection: Splash proof goggles and full face shield should be worn at all times. 3) ENGINEERING CONTROLS: Eye wash and shower stations should be available in areas where acid is being handled.
