V. FIRE AW EXPLOSION HAZARD VATA
Flash Point (Method used): Below Ambient
Handle and store in accordance with NFPA procedure for Compressed Gas, Flammable.
Extinguishing Media: If gas has ignited, do not extinguish. Stop gas flow. Allow to burn out.
Special Fire Fighting Procedures: Stop flow of gas. Use water to keep fire-exposed containers cool and to protect personnel effecting the shutoff. If a leak or spill has not ignited, use water spray to disperse the gas or vapor and to protect personnel attempting to stop a leak.
Unusual Fire and Explosion Hazards: Highly flammable. Products of combustion may contain carbon monoxide, carbon dioxide and other toxic materials. Do not enter enclosed or confined space without proper protective equipment including respiratory protection.

Precautions To Be Taken In Handling And Storing: Product is Compressed Gas, Flammable per NFPA Code No. 30-1984. Store and handle accordingly.
Shipping Information: Not To Be Transported By Truck, Rail, Air or Water.
OSHA Label: DANGER, CONTAINS BENZENE, CANCER HAZARD.
Minimize exposure. Product contains hydrocarbons which may cause irritation to eyes, skin, and lungs after prolonged or repeated exposure. The product may also be toxic to the liver, kidney, blood, and blood-forming tissues. Aspiration into the lungs may cause pneumonia.
Vapors reduce oxygen available for breathing. The use in poorly ventilated areas may cause weakness, dizziness, confusion, or unconsciousness and may lead to asphyxiation. Contact with compressed or liquified product may cause frostbite. This product may contain hydrogen sulfide which is irritating at low concentrations to the eyes, skin, and lungs. At higher concentrations, loss of ability to smell hydrogen sulfide, respiratory paralysis, and death may occur.
FIRST AID: If swallowed, do not induce vomiting.
Avoid ignition sources.

VII. HEALTH HAZARD INFORMATION
Benzene: PEL TWA. 1 ppm; STEL. 5 ppm
TLV TWA. 10 ppm Du Pont AEL TWA. 10 ppm
Hydrogen Sulfide: PEL Ceiling of 20 ppm: IQ-minute maximum peak of 50 ppm TLV TWA. 10 ppm; STEL, 15 ppm
Du Pont AEL TWA. 10 ppm
Petroleum Distillates: PEL TWA. 500 ppm
Primary Route(s) of Entry: Inhalation.
Signs and Symptoms of Exposure/Medical Conditions Aggravated By Exposure:
Extreme exposure or aspiration into the lungs may cause pneumonia. Overexposure may cause weakness, headache, nausea, confusion, blurred vision, drowsiness, and other nervous system effects; greater exposure may cause dizziness, slurred speech, flushed face, unconsciousness, or convulsions. Large concentrations in ambient air can cause asphyxiation due to oxygen displacement. Contact with compressed or liquified gas may cause frostbite.
The product contains petroleum hydrocarbons which may cause irritation to the eyes, skin, and lungs after prolonged or repeated exposure. The product may contain low concentrations of ammonia and thus enhance the irritant properties of the product.
A few studies have indicated that workers exposed many years to high concentrations of benzene have a slightly higher incidence of leukemia. Benzene can also be toxic to the blood and blood-forming tissues.
Hydrogen sulfide can be irritating at low concentrations to the eyes, skin, and respiratory tract. At higher concentrations, loss of ability to smell hydrogen sulfide, respiratory paralysis, and death may occur.
Is Product Listed as Carcinogen or Potential Carcinogen by: NTP? No IARC? No OSHA? No

VIII. EMERGENCY AND FIRST AID PROCEDURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes and seek medical attention.
Skin: Remove contaminated clothing as soon as possible. Wash exposed skin thoroughly with soap and water. If irritation develops, consult a physician.
See Section X for Precautionary Measures.
Inhalation: Because hydrogen sulfide can cause death, rescuers must wear positive
pressure full facepiece, self-contained or supplied-air NIOSH approved
respirators before attempting the rescue, if hydrogen sulfide is present. Remove
victim to fresh air immediately.
If breathing stops, begin artificial
resuscitation. Keep victim warm and at rest. Seek medical attention.
Ingestion: If this material is swallowed, do not induce vomiting. If vomiting begins, lower victim's head in an effort to prevent vomitus from entering lungs. Seek medical attention. Never give anything by mouth to an unconscious person.
Note to Physician: Gastric lavage by qualified medical personnel may be considered, depending on quantity of material ingested.
IX. SPILL, LEAK AND DISPOSAL PROCEDURES
RCRA HAZARDOUS WASTE: Yes X
No
In Case Of Spill Or Leak: Evacuate all personnel downwind of release. If released indoors, evacuate building until vapors have been cleared. Extinguish all ignition sources. Use appropriate protective clothing, rubber gloves, safety goggles and respiratory apparatus (see Section X).
Waste Disposal Method: When feasible, vapors should be dispersed mechanically.
X. PRECAUTIONARY MEASURES
Respiratory Protection: Select appropriate NIOSH-approved respiratory protective equipment where atmospheric concentrations exceed permissible exposure limits.
Ventilation: Sufficient to maintain at conditions below permissible exposure limits.
Protective Gloves: None required.
Eye Protection: Use a full facepiece with the respirator when the atmospheric concentration of hydrogen sulfide exceeds the permissible exposure limit.
Other Protective Equipment: None required.
