Section III – Hazard Identification
Potential Acute Health Effects: Eyes and Skin: Inhalation: Ingestion: Potential Chronic Health Effects: CARCINOGENICITY LISTS

Can cause severe burns or irritation. Liquid contact can cause irritation, corneal burns, and conjunctivitis. Blindness, severe or permanent injury may result. Mist contact may irritate or burn. Can cause severe burns or irritation. Avoid all contact with skin. Inhalation of fumes or acid mist can cause irritation or corrosive burns to the upper respiratory system, including nose, mouth, and throat. Lung irritation and pulmonary edema can also occur. Can cause irritation and corrosive burns to mouth, throat and stomach. Can be fatal if swallowed. (1) Erosion of Teeth, (2) Lesions of the skin (3) Tracheo-Bronchitis, (4) Mouth inflammation (5) Conjunctivitis, (6) Gastritis, Ref. (A) OSHA Standard at 29 CFR 1910.1000 (1989)
IARC Monograph: Yes






"Included based on liquid sulfuric acid concentration, however, basis of carcinogenicity listing is sulfuric acid mist."

Section IV – First Aid Measures
Eyes: Skin: Ingestion: Inhalation: Immediately flush with plenty of water continuing for at least 20 minutes. Remove contaminated clothing. Continue flushing until medical attention is available. Immediately flush with plenty of water continuing for at least 15 minutes. Remove contaminated clothing. Continue flushing until medical attention is available. Drink large amounts of water (or milk if available) to dilute the acid. Do not induce vomiting. Get medical attention immediately. Remove to fresh air. Observe for possible delayed reaction. If breathing has stopped, give artificial respiration. If breathing with difficulty, give oxygen.

Section V – Fire Fighting Measures
Flash Point: Lower Explosive Limit: Unusual Fire and Explosion Hazards: Non-flammable Not Applicable Autoignition Temperature: Upper Explosive Limit: Not Applicable Not Applicable

Flammable and potentially explosive hydrogen gas can be generated inside metal drums and storage tanks. Concentrated acid (as sold) can ignite combustible materials on contact. Fire extinguishing agents RECOMMENDED: Use water spray or other suitable agent for fires adjacent to non-leaking tanks or other containers of sulfuric acid. Fire extinguishing agents to AVOID: Do not use solid water streams near ruptured tanks or spills of sulfuric acid. Acid reacts violently with water and can splatter acid on to personnel. At high temperatures, sulfuric acid mist or sulfur trioxide gas can be released from vented or ruptured containers. If water is added to concentrated sulfuric acid, violent splattering can occur, and considerable heat may be generated. Cool non-leaking fire-exposed containers with water spray.

Special Firefighting Procedures and Equipment:

Section VI – Accidental Release Measures
Small Spill: Large Spill: Dilute “small spills” or leaks cautiously with plenty of water. Neutralize residue with alkali such as soda ash or lime. Adequate ventilation is required for soda ash due to release of carbon dioxide gas. No smoking in spill area. For major spills keep unprotected persons away. Protected persons should contain the acid by diking the spill with soil or clay. Recover the acid if possible. If spill could potentially enter any waterway, including intermittent dry creeks, contact the local authorities. If in the U.S., contact the US COAST GUARD NATIONAL RESPONSE CENTER toll free number 800-424-8802. In case of accident or road spill notify: CHEMTREC IN USA at 800-424-9300; CANUTEC in Canada at 613-996-6666 CHEMTREC in other countries at (International code)+1-703-527-3887. See Section XIII for disposal information and Section XV for regulatory requirements. Large and small spills may have a broad definition depending on the user's handling system. Therefore, the spill category must be defined at the point of release by technically qualified personnel.

Release Notes:


Section VII – Handling and Storage
Ventilation: Handling: Sufficient to reduce vapor and acid mists to permissible levels. Keep sources of ignition away. Do not get in eyes, on skin or on clothing. Do not breathe vapor or mist. Use with adequate ventilation and use protective equipment as outlined. Do not add water to acid. When diluting, always add acid to water, using caution and proper agitation. Causes Severe burns. Store in cool, well-ventilated area away from combustibles and reactive chemicals. Vent metal containers weekly or more frequently in hot weather to prevent hydrogen gas buildup. Diking of storage tanks is recommended. Vapor may contain explosive hydrogen. To prevent ignition of this if present, smoking, flames and sparks should not be permited in storage areas.


Section VIII – Exposure Controls/ Personal Protection
Engineering Controls: Packaging and unloading areas and open processing equipment may require mechanical exhaust systems. Corrosion-proof construction recommended At a minimum, wear hard hat, chemical safety goggles, and full-face plastic shield. Do not wear contact lenses. For increased protection, use supplied-air acid hood. At a minimum, wear acid-resistant apron, protective clothing, boots and gauntlet gloves for routine product use. For increased protection, include acid-resistant trousers and jacket. Where required, use a respirator approved by NIOSH for sulfuric acid or mists, as applicable. Some exposures may require a self-contained breathing apparatus with full face piece or supplied air-respirator with a full face piece, helmet or hood. Eyewash and quick-drench shower facilities, protected from freezing, should be available wherever Oleum is stored or handled.

Section X – Stability and Reactivity
Stability: Hazardous Polymerization: Conditions to Avoid: This product is stable under normal ambient conditions of temperature and pressure. Will not occur Elevated temperature yields sulfur trioxide gas which is toxic, corrosive and an oxidizer. Nitro compounds, carbides, dienes, alcohols (when heated); cause explosions, oxidizing agents, such as chlorates and permanganates: Cause fires and possibly explosions. Incompatibility – alkyl compounds and aldehydes: Undergo polymerization, possibly violent. Alkalis, amines, water, hydrated salts, carbozylic acid anhydrides, nitriles, olefinic organics, glycols, aqueous acids: Cause strong exothermic reactions. Carbonates, cyanides, sulfides, sulfites, metals such as copper: Yield toxic gases. Also for metals see hydrogen generation. Sulfur trioxide gas: See above. Also this is a fire risk in contact with organic materials.

Special Remarks on Chronic Effects on Humans

The International Agency for Research on Cancer (IARC) classified "strong inorganic acid mists containing sulfuric acid" as a Category 1 carcinogen, a substance that is "carcinogenic to humans". The National Toxicity Program classified "strong inorganic acid mists containing sulfuric acid" as a "known human carcinogen". These classifications are for strong inorganic acid mists only and do not apply to sulfuric acid or sulfuric acid solutions. The basis for the classifications rest on several epidemiology studies which have several deficiencies. These studies did not account for exposure to other substances, some known to be animal or potential human carcinogens, social influences (smoking, etc.) and included small numbers of subjects. Based on the overall weight of evidence from all human and chronic animal studies, no definitive casual relationship between sulfuric acid mist exposure and respiratory tract tumors has been shown. When handling this material avoid the creation of mist. High concentrations can irritate skin and mucous membranes and cause eye damage. Inhalation at high concentrations for longer periods may cause respiratory infection and digestive tract disturbances.
