Contains benzene. If exposure concentrations exceed the 0.5 ppm action level, OSHA requirements forpersonal protective equipment, exposure monitoring, and training may apply (29CFR1910.1028). Also see Section 4.
Potential Health Effects:
Eye: Contact may cause mild eye irritation including stinging, watering, and redness.
Skin: Skin irritant. Contact may cause redness, itching, burning, and skin damage. Prolonged or repeatedcontact can worsen irritation by causing drying and cracking of the skin, leading to dermatitis(inflammation). Not acutely toxic by skin absorption, but prolonged or repeated skin contact may beharmful (see Section 11).
Inhalation (Breathing): Low to moderate degree of toxicity by inhalation.
Ingestion (Swallowing): Low degree of toxicity by ingestion. ASPIRATION HAZARD - This material can enter lungs during swallowing or vomiting and cause lung inflammation and damage.
Signs and Symptoms: Effects of overexposure may include nausea, vomiting, flushing,transient excitation followed by signs of nervous system depression (e.g., headache, drowsiness,dizziness, loss of coordination, disorientation and fatigue), blurred vision, tremors, respiratoryfailure, unconsciousness, convulsions and death.
Cancer: Possible cancer hazard (see Sections 11 and 15).
Target Organs: Inadequate evidence available for this material. See Section 11 for target-organ toxicity information of individual components, if any.
Developmental: No harm to the fetus was observed in laboratory animal studies.
Other Comments: Reports have associated repeated and prolonged occupational overexposureto solvents with permanent brain and nervous system damage (sometimes referred to as Solvent or Painters'Syndrome). Intentional misuse by deliberately concentrating and inhaling this material may be harmful orfatal.
Pre-Existing Medical Conditions: Conditions aggravated by exposure may include skindisorders and respiratory (asthma-like) disorders.
Exposure to high concentrations of this material may increase the sensitivity of the heart to certaindrugs. Persons with pre-existing heart disorders may be more susceptible to this effect (see Section 4 Note to Physicians).
Eye: If irritation or redness develops, move victim away from exposure and into fresh air. Flush eyeswith clean water. If symptoms persist, seek medical attention.
Skin: Remove contaminated shoes and clothing, and flush affected area(s) with large amounts of water. If skin surface is damaged, apply a clean dressing and seek medical attention. If skin surface is notdamaged, cleanse affected area(s) thoroughly by washing with mild soap and water. If irritation or redness develops, seek medical attention.
Inhalation (Breathing): If respiratory symptoms or other symptoms of exposure develop, move victim away fromsource of exposure and into fresh air. If symptoms persist, seek immediate medical attention. If victim is notbreathing, clear airway and immediately begin artificial respiration. If breathing difficulties develop, oxygenshould be administered by qualified personnel. Seek immediate medical attention.
Ingestion (Swallowing): Aspiration hazard: Do not induce vomiting or give anything by mouth because thismaterial can enter the lungs and cause severe lung damage. If victim is drowsy or unconscious andvomiting, place on the left side with the head down. If possible, do not leave victim unattended and observeclosely for adequacy of breathing. Seek medical attention.
Note To Physicians: Epinephrine and other sympathomimetic drugs may initiate cardiacarrhythmias in persons exposed to high concentrations of hydrocarbon solvents (e.g., in enclosedspaces or with deliberate abuse). The use of other drugs with less arrhythmogenic potential shouldbe considered. If sympathomimetic drugs are administered, observe for the development of cardiacarrhythmias.
Federal regulations (29 CFR 1910.1028) specify medical surveillance programs for certain exposuresto benzene above the action level or PEL (specified in Section (i)(1)(i) of the Standard). In addition, employees exposed in an emergency situation shall, as described in Section (i)(4)(i), provide a urine sample at the end of the shift for measurement of urine phenol.
Flammable Properties: Flash Point: -49°F/-45°C OSHA Flammability Class: Flammable Liquid LEL%: 1.4 / UEL%: 7.6Autoignition Temperature: 833°F/444°C
Unusual Fire & Explosion Hazards: This material is extremely flammable and can be ignited by heat, sparks,flames, or other sources of ignition (e.g., static electricity, pilot lights, mechanical/electrical equipment, andelectronic devices such as cell phones, computers, calculators, and pagers which have not been certified asintrinsically safe). Vapors may travel considerable distances to a source of ignition where they can ignite, flashback, or explode. May create vapor/air explosion hazard indoors, in confined spaces, outdoors, or in sewers.Vapors are heavier than air and can accumulate in low areas. If container is not properly cooled, it can rupture inthe heat of a fire.
Extinguishing Media: Dry chemical, carbon dioxide, or foam is recommended. Water spray is recommended tocool or protect exposed materials or structures. Carbon dioxide can displace oxygen. Use caution when applyingcarbon dioxide in confined spaces. Water may be ineffective for extinguishment, unless used under favorableconditions by experienced fire fighters.
Fire Fighting Instructions: For fires beyond the incipient stage, emergency responders in the immediate hazardarea should wear bunker gear. When the potential chemical hazard is unknown, in enclosed or confined spaces, orwhen explicitly required by DOT, a self contained breathing apparatus should be worn. In addition, wear other appropriate protective equipment as conditions warrant (see Section 8).
Isolate immediate hazard area, keep unauthorized personnel out. Stop spill/release if it can be done with minimalrisk. Move undamaged containers from immediate hazard area if it can be done with minimal risk.
Water spray may be useful in minimizing or dispersing vapors and to protect personnel. Cool equipment exposed tofire with water, if it can be done with minimal risk. Avoid spreading burning liquid with water used for cooling purposes.
Extremely flammable. Keep all sources of ignition and hot metal surfaces away from spill/release. The use of explosion-proof equipment is recommended.
Stay upwind and away from spill/release. Notify persons down wind of the spill/release, isolate immediate hazardarea and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Wear appropriate protective equipment including respiratory protection as conditions warrant (see Section 8).
Prevent spilled material from entering sewers, storm drains, other unauthorized drainage systems, and natural waterways. Dike far ahead of spill for later recovery or disposal. Use foam on spills to minimize vapors (seeSection 5). Spilled material may be absorbed into an appropriate absorbent material.
Notify fire authorities and appropriate federal, state, and local agencies. Immediate cleanup of any spill isrecommended. If spill of any amount is made into or upon navigable waters, the contiguous zone, or adjoiningshorelines, notify the National Response Center (phone number 800-424-8802).
Handling: Open container slowly to relieve any pressure. Bond and ground all equipment whentransferring from one vessel to another. Can accumulate static charge by flow or agitation. Can be ignitedby static discharge. The use of explosion-proof equipment is recommended and may be required (seeappropriate fire codes). Refer to NFPA-704 and/or API RP 2003 for specific bonding/grounding requirements.
Do not enter confined spaces such as tanks or pits without following proper entry procedures such as ASTMD-4276 and 29CFR 1910.146. The use of appropriate respiratory protection is advised when concentrationsexceed any established exposure limits (see Sections 2 and 8).
Wash thoroughly after handling. Do not wear contaminated clothing or shoes. Keep contaminated clothingaway from sources of ignition such as sparks or open flames. Use good personal hygiene practices.
High pressure injection of hydrocarbon fuels, hydraulic oils or greases under the skin may have seriousconsequences even though no symptoms or injury may be apparent. This can happen accidentally when usinghigh pressure equipment such as high pressure grease guns, fuel injection apparatus or from pinhole leaks intubing of high pressure hydraulic oil equipment.
"Empty" containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill,grind, or expose such containers to heat, flame, sparks, or other sources of ignition. They may explode andcause injury or death. "Empty" drums should be completely drained, properly bunged, and promptly shipped tothe supplier or a drum reconditioner. All containers should be disposed of in an environmentally safemanner and in accordance with governmental regulations.
Before working on or in tanks which contain or have contained this material, refer to OSHA regulations, ANSIZ49.1 and other references pertaining to cleaning, repairing, welding, or other contemplated operations.
Storage: Keep container(s) tightly closed. Use and store this material in cool, dry, well-ventilatedareas away from heat, direct sunlight, hot metal surfaces, and all sources of ignition. Post area "No Smoking or Open Flame." Store only in approved containers. Keep away from any incompatible material (seeSection 10). Protect container(s) against physical damage. Outdoor or detached storage is preferred.Indoor storage should meet OSHA standards and appropriate fire codes.
Portable Containers: Static electricity may ignite gasoline vapors when filling portable containers. To avoid static buildup donot use a nozzle lock open device. Use only approved containers for the storage of gasoline. Place the container on the ground before filling. Keep the nozzle in contact with the container during filling.
Do not fill any portable container in or on a vehicle or marine craft.
Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations belowthe established exposure limits (see Section 2), additional engineering controls may be required. Where explosivemixtures may be present, electrical systems safe for such locations must be used (see appropriate electricalcodes).
Personal Protective Equipment (PPE):
Respiratory: A NIOSH certified air purifying respirator with an organic vapor cartridge maybe used under conditions where airborne concentrations are expected to exceed exposurelimits (see Section 2).
Protection provided by air purifying respirators is limited (see manufacturer's respiratorselection guide). Use a NIOSH approved self-contained breathing apparatus (SCBA) orequivalent operated in a pressure demand or other positive pressure mode if there ispotential for an uncontrolled release, exposure levels are not known, or any othercircumstances where air purifying respirators may not provide adequate protection.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2requirements must be followed whenever workplace conditions warrant a respirator's use.
Skin: The use of gloves impervious to the specific material handled is advised to prevent skincontact, possible irritation, and skin damage. Examples of approved materials arenitrile, or Viton® (see glove manufacturer literature for information on permeability).
Depending on conditions of use, apron and/or arm covers may be necessary.
Eye/Face: Approved eye protection to safeguard against potential eye contact, irritation, orinjury is recommended. Depending on conditions of use, a face shield may be necessary.
Other Protective Equipment: A source of clean water should be available in the work area for flushing eyes and skin. Impervious clothing should be worn as needed.
Suggestions for the use of specific protective materials are based on readily available publisheddata. Users should check with specific manufacturers to confirm the performance of their products.

Conditions To Avoid: Avoid all possible sources of ignition (see Sections 5 and 7).Materials to Avoid (Incompatible Materials): Contact with strong oxidizingagents such as chlorine, dichromates, or permanganates can cause fire or explosion. Hazardous Decomposition Products: The use of hydrocarbon fuel in an area withoutadequate ventilation may result in hazardous levels of combustion products (e.g., oxides of carbon, sulfur andnitrogen, benzene and other hydrocarbons) and/or dangerously low oxygen levels. See Section 11 for additional information on hazards of engine exhaust, if any.
Hazardous Polymerization: Will not occur.
Carcinogenicity: Two year inhalation studies of wholly vaporized unleaded gasoline produced increased incidences of kidney tumors in male rats and liver tumors in female mice. Follow-up studies suggest that occurrence of the kidney tumors may be linked to alpha-2-u-globulin nephropathy, and most likely unique to the male rat. Epidemiology data collected from a study of more than 18,000 petroleum marketing and distribution workers showed no increased risk of leukemia, multiple myeloma, or kidney cancer from gasoline exposure. Unleaded gasoline has been identified as a possible carcinogen by IARC.
Because solvent extracts of gasoline exhaust particulates caused skin cancer in laboratory animals, IARC has categorized gasoline engine exhaust as a possible human cancer hazard.
Target Organ(s): A two year inhalation study of wholly vaporized unleaded gasoline producednephropathy in male rats, characterized by the accumulation of alpha-2-u- globulin in epithelial cells ofthe proximal tubules, and necrosis and hyperplasia of surrounding cells. Follow-up studies havedemonstrated that these changes are unique to the male rat.Although prolonged exposure to n-hexane, a component of gasoline, has resulted in adverse malereproductive effects in experimental animal studies, no adverse male reproductive effects were found instudies conducted with gasoline.
Developmental: No evidence of developmental toxicity was found in pregnant laboratory animals(rats and mice) exposed to up to 9,000 ppm vapor of unleaded gasoline via inhalation.
Target Organ(s): A six week inhalation study with xylene produced hearing loss in rats.
Developmental: Both mixed xylenes and the individual isomers produced limited evidence ofdevelopmental toxicity in laboratory animals. Inhalation and oral administration of xylene resulted indecreased fetal weight, increased incidences of delayed ossification, skeletal variations and resorptions.
Target Organ(s): Epidemiology studies suggest that chronic occupational overexposure totoluene may damage color vision. Subchronic and chronic inhalation studies with toluene produced kidneyand liver damage, hearing loss and central nervous system (brain) damage in laboratory animals.Intentional misuse by deliberate inhalation of high concentrations of toluene has been shown to causeliver, kidney, and central nervous system damage, including hearing loss and visual disturbances.
Developmental: Exposure to toluene during pregnancy has demonstrated limited evidence ofdevelopmental toxicity in laboratory animals. The effects seen include decreased fetal body weight andincreased skeletal variations in both inhalation and oral studies.
Carcinogenicity: Benzene is an animal carcinogen and is known to produce acute myelogenous leukemia (a form of cancer) in humans. Benzene has been identified as a human carcinogen by NTP, IARC and OSHA.
Target Organ(s): Prolonged or repeated exposures to benzene vapors has been linked to bone marrow toxicity which can result in blood disorders such as leukopenia, thrombocytopenia, and aplastic anemia. All of these diseases can be fatal.
Developmental: Exposure to benzene during pregnancy demonstrated limited evidence ofdevelopmental toxicity in laboratory animals. The effects seen include decreased body weight andincreased skeletal variations in rodents. Alterations in hematopoeisis have been observed in the fetusesand offspring of pregnant mice.
Mutagenicity: Benzene exposure has resulted in chromosomal aberrations in human lymphocytes andanimal bone marrow cells, and DNA damage in mammalian cells in vitro.
Carcinogenicity: Rats and mice exposed to 0, 75, 250, or 750 ppm ethyl benzene in a two year inhalation study demonstrated limited evidence of kidney, liver, and lung cancer. Ethyl benzene has been listed as a possible human carcinogen by IARC. Ethyl benzene has not been listed as a carcinogen by NTP, or OSHA.
Target Organ(s): In rats and mice exposed to 0, 75, 250, or 750 ppm ethyl benzene in a twoyear inhalation study there was mild damage to the kidney (tubular hyperplasia), liver (eosinophilio foci,hypertrophy, necrosis), thyroid (hyperplasia) and pituitary (hyperplasia).
Target Organ(s): Excessive exposure to n-hexane can result in peripheral neuropathies. The initial symptoms are symmetrical sensory numbness and paresthesias of distal portions of the extremities.Motor weakness is typically observed in muscles of the toes and fingers but may also involve muscles ofthe arms, thighs and forearms. The onset of these symptoms may be delayed for several months to a yearafter the beginning of exposure. The neurotoxic properties of n-hexane are potentiated by exposure tomethyl ethyl ketone and methyl isobutyl ketone.
Prolonged exposure to high concentrations of n-hexane (>1,000 ppm) has resulted in decreased sperm countand degenerative changes in the testes of rats but not those of mice.

Spilling of gasoline can result in environmental damage.
Gasoline floats on water and evaporates rapidly from water or soil surfaces. However, spilled gasoline may penetrate soil and could contaminate groundwater.
Gasoline is biodegradable but in situations of low oxygen, such as in soil below grade or in groundwater, may persist for many years.
Gasoline does not readily dissolve in water but will be adsorbed to soils. Gasoline in the environment can be toxic to plants and animals.
This material, if discarded as produced, would be a RCRA "characteristic" hazardous waste due to the characteristic(s) of ignitability (D001) and benzene (D018). If the spilled or released material impacts soil, water, or other media, characteristic testing of the contaminated materials may be required prior to their disposal. Further, this material, once it becomes a waste, is subject to the land disposal restrictions in 40 CFR 268.40 and may require treatment prior to disposal to meet specific standards. Consult state and local regulations to determine whether they are more stringent than the federal requirements.
Container contents should be completely used and containers should be emptied prior to discard. Container rinsate could be considered a RCRA hazardous waste and must be disposed of with care and in full compliancewith federal, state and local regulations. Larger empty containers, such as drums, should be returned to thedistributor or to a drum reconditioner. To assure proper disposal of smaller empty containers, consult withstate and local regulations and disposal authorities.
