SECTION 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Bronze to amber colored liquid, extremely flammable, potentially hazardous vapors. Can cause eye and skin irritation upon contact. Inhalation
of vapors can cause anesthetic effect leading to death in poorly ventilated areas. Danger Poison! Harmful if swallowed and/or aspirated into the
lungs. Hazard symbols for this product - F, XI, XN Risk Phrases - R11 20 36 38.
POTENTIAL HEALTH EFFECTS
INHALATION: High concentrations are irritating to the respiratory tract; may cause headache, dizziness, nausea, vomiting and malaise. Xylene
causes central nervous system effects, anemia, liver and kidney effects, and eye damage after repeated or prolonged exposure to high
concentrations.
SKIN: Brief contact may cause slight irritation; prolonged contact may cause moderate irritation or dermatitis. Xylene causes central nervous
system effects, anemia, liver and kidney effects, and eye damage after repeated or prolonged exposure to high concentrations.
EYES: High vapor concentration or contact may cause irritation and discomfort.
INGESTION: May result in vomiting; aspiration of vomitus into the lungs must be avoided; DO NOT induce vomiting. Minute amounts aspirated
into the lungs can produce severe lung injury, chemical pneumonitis, pulmonary edema or death.
CARCINOGENICITY Yes Yes Yes
NTP? IARC MONOGRAPHS? OSHA REGULATED?
Gasoline has been classified as a Group 2B carcinogen (possibly carcinogenic to humans) by the International Agency for Research on Cancer
(IARC). Contains chemical(s) known to the State of California to cause cancer. Contains benzene, which has been classified as a carcinogen
by the National Toxicology Program (NTP), and a Group 1 carcinogen (carcinogenic to humans) by the International Agency for Research on
Cancer (IARC). Contains ethylbenzene which has been classified as a Group 2B carcinogen (possibly carcinogenic to humans) by the
International Agency for Research on Cancer (IARC).
SECTION 4 - FIRST AID MEASURES
INHALATION: Remove affected person to fresh air; provide oxygen if breathing is difficult; if affected person is not breathing, administer CPR
and seek immediate emergency medical attention.
SKIN: Remove contaminated clothing; wash affected area with soap and water; launder contaminated clothing before reuse; if irritation persists,
seek medical attention.
EYES: Remove contact lenses. Flush eyes with clear running water for 15 minutes while holding eyelids open; if irritation persists, seek medical
attention.
INGESTION: DO NOT induce vomiting; if vomiting occurs spontaneously, keep head below hips to prevent aspiration of liquid into lungs; seek
immediate medical attention. Vomiting may be induced only under the supervision of a physician.
SECTION 5 - FIRE FIGHTING MEASURES
FLAMMABLE LIMITS LEL: 1.3% UEL: 7.6%
FLASH POINT (METHOD USED)
AUTOIGNITION TEMPERATURE: 495?F (257?C) NFPA CLASS:
-45?F ( -42.7?C) TCC IA
GENERAL HAZARDS: This product presents an extreme fire hazard. Liquid evaporates very quickly, even at low temperatures, and forms
vapor (fumes) which can catch fire and burn with explosive violence. Invisible vapor spreads easily and can be set on fire by many sources such
as pilot lights, welding equipment, and electrical motors and switches.
EXTINGUISHING MEDIA
Carbon dioxide, water fog, dry chemical, chemical foam
FIRE FIGHTING PROCEDURES
Firefighters must wear full facepiece self - contained breathing apparatus in positive pressure mode. Do not use solid stream of water since
stream will scatter and spread fire. Fine water spray can be used to keep fire - exposed containers cool.
UNUSUAL FIRE AND EXPLOSION HAZARDS
Closed containers can explode due to buildup of pressure when exposed to extreme heat. Do not use direct stream of water on pool fires as
product may reignite on water surface. Caution - Material is extremely flammable!
HAZARDOUS COMBUSTION PRODUCTS
Smoke, fumes, oxides of carbon

SECTION 6 - ENVIRONMENTAL RELEASE MEASURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: CAUTION - EXTREMELY FLAMMABLE - Evacuate and ventilate
area; confine and absorb into absorbent; place material into approved containers for disposal; for spills in excess of allowable limits (RQ) notify
the National Response Center (800) 424 - 8802; refer to CERCLA 40 CFR 302 and SARA Title III, Section 313 40 CFR 372 for detailed
instructions concerning reporting requirements.
SECTION 7 - HANDLING AND STORAGE
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Keep container closed when not in use; protect containers from abuse;
protect from extreme temperatures. CAUTION - EXTREMELY FLAMMABLE - keep away from all sources of ignition. "Empty" containers may
contain residue which may form explosive vapors. Do not weld or cut near empty container that has not been professionally reconditioned. Use
non-sparking tools when opening and closing containers. Maintain well ventilated work areas to minimize exposure when handling this material.
Review all operations which have the potential of generating an accumulation of electrostatic charge and/or a flammable atmosphere (including
tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations)
and use appropriate mitigating procedures. Improper filling of portable gasoline containers creates danger of fire. Only dispense gasoline into
approved and properly labeled gasoline containers. Always place portable containers on the ground. Be sure pump nozzle is in contact with the
container while filling. Do not use a nozzle's lock-open device. Do not fill portable containers that are inside a vehicle or truck/trailer bed.
SECTION 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTR0LS
The use of local exhaust ventilation is recommended to control emissions near the source. Provide mechanical ventilation of confined spaces.
Use explosion-proof ventilation equipment. See Section 2 for Component Exposure Guidelines.
PERSONAL PROTECTION:
RESPIRATORY PROTECTION (SPECIFY TYPE): None required while threshold limits (Section 2) are kept below maximum allowable
concentrations; if TWA exceeds limits, NIOSH approved respirator must be worn. Refer to 29 CFR 1910.134 or European Standard EN 149 for
complete regulations.
PROTECTIVE GLOVES: Neoprene or nitrile rubber gloves with cuffs.
EYE PROTECTION: Safety goggles with side shields
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Safety eyewash nearby
WORK / HYGIENIC PRACTICES: Practice safe workplace habits. Minimize body contact with this, as well as all chemicals in general.

SECTION 12 - ECOLOGICAL INFORMATION
No data are available on the adverse effects of this material on the environment. Neither COD nor BOD data are available. Based on the
chemical composition of this product it is assumed that the mixture can be treated in an acclimatized biological waste treatment plant system in
limited quantities. However, such treatment should be evaluated and approved for each specific biological system. None of the ingredients in
this mixture are classified as a Marine Pollutant. In general, non-oxygenated gasoline exhibits some short-term toxicity to freshwater and marine
organisms, especially under closed vessel or flow-through exposure conditions in the laboratory. The components which are the most prominent
in the water soluble fraction and cause aquatic toxicity, are also highly volatile and can be readily biodegraded by microorganisms.
SECTION 13 - DISPOSAL CONSIDERATIONS
WASTE DISPOSAL METHOD: Dispose of in accordance with Local, State, and Federal Regulations. This product may produce concentrated
hazardous vapors or fumes in a disposal container creating a dangerous environment. Refer to "40 CFR Protection of Environment Parts 260 -
299" for complete waste disposal regulations for ignitable materials. Consult your local, state, or Federal Environmental Protection Agency
before disposing of any chemicals. Do not flush to sanitary sewer or waterway.
