Section 3 - Hazards Identification 

EMERGENCY OVERVIEW 

Appearance: Dark Bluish Green Liquid. 

Danger! Causes eye and skin burns. Causes digestive and respiratory tract burns. May be 

fatal if mist inhaled. Strong inorganic acid mists containing sulfuric acid may cause cancer. 

Concentrated sulfuric acid reacts violently with water and many other substances under 

certain conditions. May cause lung damage. Hygroscopic (absorbs moisture from the air). 

Corrosive to metal. 

Target Organs: Lungs, teeth, eyes, skin.

Potential Health Effects 

Eye: Causes severe eye burns. May cause irreversible eye injury. May cause blindness. May 

cause permanent corneal opacification. The severity of injury depends on the concentration 

of the solution and the duration of exposure. 

Skin: Causes skin burns. The severity of injury depends on the concentration of the solution 

and the duration of exposure. 

Ingestion: May cause severe and permanent damage to the digestive tract. Causes 

gastrointestinal tract burns. 

Inhalation: May cause irritation of the respiratory tract with burning pain in the nose and 

throat, coughing, wheezing, shortness of breath and pulmonary edema. Causes chemical 

burns to the respiratory tract. Inhalation may be fatal as a result of spasm, inflammation, 

edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Because its 

vapor pressure is negligible, it exists in the air only as a mist or spray. Exposure may impair 

lung function and cause mucostasis (reduced mucous clearance). 

Chronic: Prolonged or repeated skin contact may cause dermatitis. Prolonged or repeated 

inhalation may cause nosebleeds, nasal congestion, erosion of the teeth, perforation of the 

nasal septum, chest pain and bronchitis. Prolonged or repeated eye contact may cause 

conjunctivitis. Effects may be delayed. Workers chronically exposed to sulfuric acid mists 

may show various lesions of the skin, tracheobronchitis, stomatitis, conjunctivitis, or 

gastritis. Occupational exposure to strong inorganic acid mists containing sulfuric acid is 

carcinogenic to humans. 

Section 4 - First Aid Measures 

Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 

minutes. Get medical aid immediately. 

Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes 

while removing contaminated clothing and shoes. Get medical aid immediately. Wash 

clothing before reuse. 

Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is 

fully conscious, give a cupful of water. Never give anything by mouth to an unconscious 

person. 

Inhalation: POISON material. If inhaled, get medical aid immediately. Remove victim to 

fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. 

Notes to Physician: Monitor arterial blood gases, chest x-ray, and pulmonary function 

tests if respiratory tract irritation or respiratory depression is evident. Treat dermal irritation 

or burns with standard topical therapy. Effects may be delayed. Do NOT use sodium 

bicarbonate in an attempt to neutralize the acid. 

Section 5 - Fire Fighting Measures 

General Information: As in any fire, wear a self-contained breathing apparatus in 

pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use

water spray to keep fire-exposed containers cool. Substance is noncombustible. Contact 

with water can cause violent liberation of heat and splattering of the material. Contact with 

metals may evolve flammable hydrogen gas. Runoff from fire control or dilution water may 

cause pollution. Approach fire from upwind to avoid hazardous vapors and toxic 

decomposition products. Strong dehydrating agent, which may cause ignition of finely 

divided materials on contact. Oxides of sulfur may be produced in fire. 

Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. 

Do NOT get water inside containers. If water is used, care should be taken, since it can 

generate heat and cause spattering if applied directly to sulfuric acid. 

Flash Point: Not applicable. 

Autoignition Temperature: Not available. 

Explosion Limits, Lower: Not available. 

Upper: Not available. 

NFPA Rating: (estimated) Health: 3; Flammability: 0; Instability: 2; Special Hazard: -W- 

Section 6 - Accidental Release Measures 

General Information: Use proper personal protective equipment as indicated in Section 8. 

Spills/Leaks: Avoid runoff into storm sewers and ditches which lead to waterways. Clean 

up spills immediately, observing precautions in the Protective Equipment section. Carefully 

scoop up and place into appropriate disposal container. Provide ventilation. Do not get water 

inside containers. Cover with dry earth, dry sand, or other non-combustible material 

followed with plastic sheet to minimize spreading and contact with water. 

Section 7 - Handling and Storage 

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before 

reuse. Do not allow water to get into the container because of violent reaction. Do not get in 

eyes, on skin, or on clothing. Keep container tightly closed. Discard contaminated shoes. 

Use only with adequate ventilation. Do not breathe spray or mist. Do not use with metal 

spatula or other metal items. Inform laundry personnel of contaminant's hazards. 

Storage: Do not store near combustible materials. Keep container closed when not in use. 

Store in a cool, dry, well-ventilated area away from incompatible substances. Do not store 

near alkaline substances. Store protected from moisture. Ideally, sulfuric acid should be 

stored in isolation from all other chemicals in an approved acid or corrosives safety cabinet. 

Section 8 - Exposure Controls, Personal Protection 

Engineering Controls: Facilities storing or utilizing this material should be equipped with 

an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation

to keep airborne concentrations below the permissible exposure limits. Use a corrosionresistant 

ventilation system.

Personal Protective Equipment 

Eyes: Wear chemical splash goggles and face shield. 

Skin: Wear neoprene gloves, apron, and/or clothing. Viton gloves are recommended.

Carcinogenicity: 

CAS# 7664-93-9: 

• ACGIH: A2 - Suspected Human Carcinogen (contained in strong inorganic acid 

mists) 

• California: carcinogen, initial date 3/14/03 (listed as Strong inorganic acid mists 

containing sulfuric acid). 

• NTP: Known carcinogen (listed as Strong inorganic acid mists containing s). 

• IARC: Group 1 carcinogen 

Epidemiology: Workers exposed to industrial sulfuric acid mist showed a statistical 

increase in laryngeal cancer. This suggests a possible relationship between carcinogenesis 

and inhalation of sulfuric acid mist. 

Teratogenicity: Sulfuric acid was not teratogenic in mice and rabbits, but was slightly 

embryotoxic in rabbits (a minor, rare skeletal variation). The animals were exposed to 5 and 

20 mg/m3 for 7 hr/day throughout pregnancy. Slight maternal toxicity was present at the 

highest dose in both species. 

Reproductive Effects: No information found 

Mutagenicity: There are no mutagenicity studies specifically of sulfuric acid. However, 

there are established effects of reduced pH in mutagenicity testing, as would be caused by 

sulfuric acid. These effects are an artifact of low pH and are not necessarily due to biological 

effects of sulfuric acid itself. 

Neurotoxicity: No information found 

Other Studies:

Section 12 - Ecological Information 

Ecotoxicity: Fish: Bluegill/Sunfish: 49 mg/L; 48Hr; TLm (tap water @ 20C) 

Fish: Bluegill/Sunfish: 24.5 ppm; 48Hr; TLm (fresh water)
