Section 4 - Fire And Explosion Hazard Data
Flash Point: Flammable Limits: LEL: UEL:
Not flammable N/A N/A N/A
Extinguishing Media: For fires in the area, use approved extinguishing media such as water, CO虏 or dry chemical.
Use water spray or fog to knock down corrosive vapor cloud.
Special Firefighting Procedures:
Product is non-flammable, but high temperature of surrounding fire may generate corrosive and toxic sulfur trioxide
gases. Use NIOSH/OSHA approved self contained breathing apparatus and full protective clothing. Cool containers
that are exposed to flames with streams of water until fire is out. Caution: water applied directly to product results in
evolution of heat and causes spattering.When heated, product will emit highly toxic fumes.
Unusual Fire And Explosion Hazards:
Product may react violently with water creating heat and steam and dangerous spattering. Contact with some
materials will release hydrogen gas, creating additional potential fire and explosion hazard.

Section 5 - Reactivity Data
Avoid temperatures greater than 300潞C. Yields toxic and corrosive
Stability: Conditions To Avoid:
Stable
sulfur trioxide gases. Do NOT add water. Do not mix with caustic or
alkali.
Incompatability Organics, chlorates, carbides, fulminates, picrates, metals, acids. Reacts readily with many
(Materials To Avoid): chemicals -- DO NOT mix with any other chemical. Product will destroy most organic materials.
Hazardous Decomposition: Sulfur trioxide gas, sulfuric acid mist, sulfur dioxide at elevated temperatures.
Hazardous Polymerization: Will Not Occur
Section 6 - Health Hazard Data
Inhalation? Yes Yes Ingestion? Yes
Routes of Entry: Skin?
Health Hazards:
CORROSIVE TO ALL BODY TISSUES. EYES: Mist or solution rapidly causes severe irritation of the eyes and
eyelids if not removed by prompt and thorough irrigation with water. Liquid can cause irritation, corneal burns, and
NO
conjunctivitis leading to severe or permanent injury and/or loss of sight. SKIN: Contact with liquid causes severe
burns unless immediately and thoroughly washed off. Exposure to concentrated mist may cause burns or
dermatitis. INGESTION: If swallowed, will cause serious burns to mucous membranes of the mouth, throat, and
stomach, or perforation of the esophagus and/or stomach. Ingestion can be fatal. INHALATION: Mist causes
irritation or corrosive burns to respiratory system, including nose, mouth, throat and esophagus, with immediate
pain and difficulty in swallowing. Lung irritation as well as laryngeal, tracheobronchial, and pulmonary edema can
also occur. Inhalation may be fatal.
Carcinogenicity: NTP? NO IARC? NO OSHA Regulated?
NOTE: Sulfuric acid mist is listed as a known carcinogen by both the NTP and IARC.
Signs And Symptoms of Exposure:
See "Health Hazards" above. Repeated or prolonged exposure to low concentrations have been reported to cause;
erosion of teeth, irritation and lesion of skin, tracheobronchitis, mouth inflammation, conjunctivitis, and frequent
respiratory infections, emphysema, and digestive disorders.
Medical Conditions Generally Aggravated By Exposure:
Chronic respiratory diseases or conditions including asthma, bronchitis, emphysema, nervous system diseases, eye
and skin disorders and conditions.
Emergency And First Aid Procedures:
EYES: Flush with plenty of gently running water for at least 15 minutes. Forcibly hold eyelids apart to ensure flushing
of all eye and eyelid tissue (Washing eyes within 1 minute is essential to achieve maximum effectiveness. Get
immediate medical attention, but do not transport unless flushing is completed or can be continued in transit. SKIN:
Flush contaminated areas thoroughly with plenty of water for at least 15 minutes. Remove contaminated clothing. If
large areas of the body are contaminated or clothing is penetrated, immediately use safety shower. Remove
contaminated clothing and footwear. After washing skin cover affected area with moist milk of magnesia or baking
soda. GET IMMEDITE MEDICL ATTENTION, but complete flushing prior to transport. Wash and decontaminate
clothing/footwear. INHALATION: Remove to fresh air. CALL EMERGENCY MEDICAL CARE. IF breathing has
stopped, use artificial respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen. INGESTION: Do
NOT induce vomiting. Give large amounts of water or milk and immediately call EMERGENCY MEDICAL CARE. Do
not give carbonates. If vomiting occurs, keep airways clear. NEVER GIVE ANYTHING BY MOUTH TO AN
UNCONSCIOUS PERSON. NOTE TO PHYSICIANS: This material is extremely corrosive to all body tissues. IF
swallowed, gastric lavage should be used only with extreme caution.

Section 7 - Precautions For Safe Handling And Use:
Steps To Be Taken In Case Material Is Released Or Spilled:
SMALL SPILLS: Do not allow any contact with acid, mist, or vapors. Dilute spill with copious amounts of water, If
practical and safe flush to sewer. Neutralize remaining mat'l with baking soda. If flushing to sewer is not safe, contain
diluted spill with any inert absorbent then neutralize with baking soda (sodium bicarbonate). FOR LARGER SPILLS:
Use NIOSH/OSHA respirator and full protective clothing. No skin surface should be exposed. Notify fire/health
authorities. Neutralize with lime or soda ash. If applicable due to runoff, notify pollution authorities.
Waste Disposal Method:
Materials resulting from cleanup may be hazardous. Package, store, transport and dispose of in accordance with
appropriate Federal, State and Local regulations. Be sure that all responsible agencies are informed of disposal.
Precautions To Be Taken In Handling And Storing:
Handle with extreme care. Store containers upright during transportation, storage and handling. Have applicable first
aid equipment and running water available. NEVER add cold water to product in container. Do not use or mix with any
other chemical -- a violent eruption of hot corrosive acid can occur. Store in upright position at floor level only
Other Precautions:
Store in cool dry place. Keep separate from alkalis, metal explosives and easily ignitable material.
