Special Fire Fighting Procedure: Evacuate area and fight fire from a safe distance or a protected loca- tion. Approach fire from upwind. Containers may explode in the heat of the fire. Use water in flooding quantities as a spray or fog to keep fire-exposed containers cool. Apply water, as an extinguishant or as a coolant from as far a distance as possible. Move containers away from fire area if it can be done without risk.avoid spraying water directly into the acid container. Do not direct water spray at source of leak. Use water spray or fog to reduce or direct vapors. Do not enter without wearing specialized protective equipment suitable for the situation. Firefighter's normal protective clothing (bunker gear) will not provide adequate protection. A full- body encapsulated chemical resistant suit with positive pressure self- contained breathing apparatus (msha/ niosh approved or equivalent) may be necessary. Trained personnel may neutralize spill. Fire And Explosion Hazards: Contact with most metals especially when sulfuric acid is diluted with water produces highly flammable hydrogen gas which may form explosive mixture in air. Fire may result from the heat generated by contact of concentrated sulfuric acid with combustible materials. Sulfuric acid reacts violently with water and organic materials with evolution of heat. During fire, irritating/toxic sulfur oxides may be generated. Containers may explode in the heat of a fire. Autoignition Temperature: NA TDG Flammability Classification: Not Flammable Toxic Combustion Gases: Oxides of sulfur Sensitivity To Mechanical Impact : None identified Sensitivity To Static Discharge: None identified ---------------------------------------------------------------------- Section 5 - Health Hazard Data ---------------------------------------------------------------------- Threshold Limit Value( TLV / TWA ):1 mg/m3 STEL / PEL : 1 mg/m3 LD 50 (Oral, Rat) mg/kg: 2140 (2) LC 50 (Mouse) mg/m3: 320 (2-Hour Exposure); 160 (Equivalent 4-Hour Exposure) (1) LC 50 (Rat) mg/m3 : 510 (2-Hour Exposure); 255 (Equivalent 4-Hour Exposure) (1) Carcinogenicity: Iarc Has Concluded There Is Sufficient Evidence That Occupational Exposure To Strong Inorganic Acid Mists Containing Sulfuric Acid Is Carcinogenic To Humans (Group 1)(6). Many studies have reported an excess of cancer of larynx, and to a lesser extent the lungs, in a wide variety of processes involving the use of strong inorganic acids including sulfuric acid. Throughout these studies,sulfuric acid mists were the most common exposure, and in two studies, the number of cancers increased as exposure increased (6). NTP: No IARC: No Z List: Yes OSHA Reg: Yes Teratogenicity And Embryotoxicity: NA (No Human Information Is Available). Mutagenicity: There was a significantly higher number of sister chromatoid exchanges, micronuclei and chromosomal aberations in cultured lymphocytes (white blood cells) from workers exposed to sulfur dioxide in a sulfuric acid factory (6). Reproductive Toxicity/Synergistic Effects: NA Primary Routes Of Entry: Eye contact, skin contact, inhalation of mist, and ingestion. Acute Effects Of Exposure: Inhalation: Sulfuric acid is corrosive and can cause severe irritation or corrosive damage if inhaled. The degree and severity of respiratory effects are influenced by factors such as the physical state and particle size of the aerosol or mist, deposition site, concentration and humidity. Sulfuric acid can cause severe lung damage with a life-threatening accumulation of fluid in the lungs (pulmonary edema). The symptoms of pulmonary edema such as coughing and short- ness of breath can be delayed for several hours or days after the exposure. These symptoms are aggravated by Physical exertion. Long term lung damage may result from a severe short term exposure (5).Asthma can be aggravated by exposure to sulfuric acid (5,12,13). Skin Contact: Can cause severe burns and irritation (redness,swelling, and pain) which may result in permanent scarring. Extensive acid burns can result in death. High mist or aerosol concentration may cause redness, irritation and burns to the skin if contact is prolonged. Eye Contact: Can cause severe irritation, burns and permanent damage including blindness. Ingestion: Sulfuric acid is corrosive and can cause burns to the mouth,throat,esophagus and stomach if ingested. Symptoms may include difficulty in swallowing, intense thirst, nausea,vomiting, diarrhea, and in severe cases,collapse and death. Small amounts of acid which enters the lungs during ingestion or vomiting (aspiration) can cause serious lung injury and death. Skin Absorption: Non Identified Chronic Effects Of Exposure: Dental Erosion: Exposure to high concentrations ( reportedly up to 16 mg / m3 ) cause dental erosion (10). etching of teeth may occur after a few weeks exposure, progressing to erosion after a few months exposure (5). Dental etch- ing and erosion occurred about 4 times as frequently in a high exposure group(over 0.3 mg/m3) compared to a low exposure group (below 0.07 mg/m3).(6) Skin Effects: Repeated exposure to low concentration of acid mists or aerosols can cause dermatitis (red, itchy, dry skin). Inhalation Effects: Repeated exposure to sulfuric acid mists or aerosol could cause symptoms of respiratory irritation such as bronchial hyperreactivity. Target Organs: Respiratory system, eyes, skin, teeth, and kidneys. Other Health Hazards: Medical Conditions Generally Aggravated By Exposure: Respiratory disease, and damaged skin. Emergency And First Aid Procedures: Ingestion: Never give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Have victim rinse mouth thoroughly with water. Do not induce vomiting. have victim drink 240-300 ml (8 to 10 oz.) of water. If milk is available it may be administered after the water has been given. If vomiting occurs naturally,have victim lean forward to reduce risk of aspiration. Repeat admin- istration of water.quickly,transport victim to an emergency facility. Inhalation: Take proper precautions to ensure your own safety before attempting rescue; e.g., wear appropriate protective equipment, use the " buddy " system. Remove source of contamination or move victim to fresh air. If breathing is difficult, oxygen may be beneficial if administered by a person trained in its use, preferably on a physician’s advice. Ensure victim is completely at rest, do not allow any physical exertion. Symptoms may be delayed up to 48 hours after exposure. Immediately transport victim to an emergency medical facility. Eye Contact: In case of eye contact, immediately flush the affected eye(s) with plenty of lukewarm water, gently flowing water for at least 20-30 minutes, by the clock, holding the eyelid(s) open. Neutral saline solution may be used as soon as it is available. Do not interrupt flushing. If necessary, keep emergency vehicle waiting. Take care not to rinse contaminated water into the non-affected eye. If irritation persists, repeat flushing. Quickly, transport victim to an emergency facility. Skin Contact: Immediately flush skin with lukewarm water for at least 20-30 minutes, by the clock. Under running water, remove contaminated clothing, shoes, and leatherwears (e.g., watchbands, belts). Do not interrupt flushing. If Necessary, keep emergency vehicle waiting. transport victim to an emergency care facility immediately. Com- pletely decontaminate clothing,shoes, and leatherwears before reuse or discard. --------------------------------------------------------------------- Section 6 - Reactivity Data --------------------------------------------------------------------- Stability: Stable under 340 Deg C Conditions To Avoid: Heat and water Hazardous Polymerization: Will not occur. Decomposition Products: Hydrogen and oxides of sulfur Incompatibles: Can react with most metals generating flammable hydrogen gas.React vigorously, violently or explosively with many organic and inorganic chemicals including water, acrylonirile, alkali solutions, carbides, chlorates, fulminates, nitrates, perchlorates, permangenates, picrates, metal acetylides or carbides, epichlorohydrin, aniline, ethylenediamine, alcohols with strong hydrogen peroxide, chlorosulfonic acid, cyclopentadiene, hydrofluoric acid,nitromethane, 4- nitrotoluene, phosphorous (iii) oxide, potassium, sodium, ethylene glycol,isoprene, styrene (15,17,18). Acetaldehyde and allyl chloride may polymerize violently in the presence of sulfuric acid (17). Hazardous gases such as hydrogen cyanide, hydrogen sulfide, and acetylene, are evolved on contact with chemicals such as cyanides, sulfides and carbides (16). References 15, 17, and 18 provide more complete lists of chemicals that may produce hazardous chemical reactions with sulfuric acid. Corrosivity To Metals: Very corrosive to most metals. Oxidizing Properties: Pure or concentrated sulfuric acid is a good oxidizing agent(23), while hot concentrated sulfuric acid is a strong oxidizing agent (24). Although the degree of oxidizing ability of sulfuric acid may vary from concentrated to dilute, or, from room temperature to hot, sulfuric acid is nevertheless an oxyacid with oxidizing ability. Effect On Plastics: Many plastics do not resist concentrated sulfuric acid of greater than 50-60%. Teflon is the only common plastic that resists at all concentrations (14). --------------------------------------------------------------------- Section 7- Spill And Disposal Procedure --------------------------------------------------------------------- Steps To Be Taken In The Event Of A Spill Or Discharge: Precautions: Restrict access to area until completion of cleanup. Ensure cleanup is conducted by fully-trained personnel only. wear adequate personal protective equipment. Remove or isolate flammable or incompatible materials. Ventilate area. Notify government occupational health and safety and environmental authorities. Clean-Up: Do not touch spilled material. Keep upwind and out of low areas. Avoid inhaling vapor. Stop or reduce leak if it can be done without risk. Prevent material from entering sewers, waterways, or confined spaces. Recover spilled acid if feasible. Contain spill with earth,sand, or absorbent material which does not react with spilled chemical. For small spills, contain and soak up spill with absorbent material which does not react with spilled chemical. Put material in suitable, covered, labeled container. Fush area with water. Do not get water inside containers. Contaminated absorbent material may pose the same hazards as the spilled product. For large spills, contact fire and emergency services and supplier for advice. Water fog or spray may be necessary to knock down vapors. Disposal Procedure: Dispose in accordance with all applicable federal, state, and local environmental regulations.
