This CHEMINFO record refers to common, commercial unleaded gasoline used
for automotive purposes, unless otherwise specified.
.
Gasoline is a complex mixture of petroleum hydrocarbons. The composition
of the hydrocarbons depends on factors such as the origin of the crude oil
used for refining and refining conditions. In general, the hydrocarbon
groups consist of chains containing 4 to 12 carbons, and are mostly
paraffins (alkanes), isoparaffins (isoalkanes), cycloparaffins
(cycloalkanes) and aromatics. n -Hexane (1.5-3.0%) and benzene (0.5-2.0%)
are normally present.
.
In addition, trace or small amounts of additives and blending agents such
as anti-knock compounds (MMT - methylcyclopentadienyl manganese
tricarbonyl), anti-icing agents, anti-rust agents and metal deactivators
can be found in gasoline.
.
The chemical and physical properties of gasoline are highly variable
depending on the specific product. As well, the ha zards of gasoline are
affected by the proportion of individual components. For example, gasoline
containing a significant proportion of n-hexane may have toxic effects
attributable to n- hexane. For information on specific components in
gasoline consult the manufacturer or the appropriate CHEMINFO record.
USES AND OCCURRENCES :
Fuel for motor vehicles; some use as diluent and solvent.

*** SECTION 3. HAZARDS IDENTIFICATION ***

** EMERGENCY OVERVIEW **

Colourless liquid with characteristic odour. May be dyed yellow.
EXTREMELY FLAMMABLE LIQUID AND VAPOUR. Liquid can accumulate static charge
by flow or agitation. Vapour is heavier than air and may spread long
distances. Distant ignition and flash back are possible. Liquid can float
on water and may spread to distant locations and/or spread fire. POSSIBLE
CANCER HAZARD. May cause cancer, based on animal data. Central nervous
system depressant. High vapour concentrati ons may cause headache, nausea,
dizziness, drowsiness, unconsciousness and death. Aspiration hazard.
Swallowing or vomiting of the liquid may result in aspiration into the
lungs.

** POTENTIAL HEALTH EFFECTS **


EFFECTS OF SHORT-TERM (ACUTE) EXPOSURE :
INHALATION :
Gasoline vapours can cause central nervous system (CNS) depression.(1) No
significant effects except eye and throat irritation were seen in
volunteers exposed for 30 minutes to concentrations as high as 1054 ppm, or
for 8 hours to concentrations around 150-270 ppm.(6,7) Mild dizziness was
experienced by volunteers exposed for 1 hour to 2600 ppm. Pronounced
dizziness was experienced by volunteers after about 5 minutes exposure to
about 1100 ppm.(6) Other CNS effects such as headache, lack of appetite,
drowsiness and incoordination can occur. In one case, exposure for a few
minutes to very high concentrations (above 5000 ppm) of aviation gasoline
caused unconsciousness, pulmonary edema (a life-threatening accumulation of
fluid in the lungs) and death.(15)
SKIN CONTACT :
When gasoline is NOT trapped against the skin and can freely evaporate, it
is probably only mildly irritating or not irritating. However, case
reports indicate that when gasoline is trapped against the skin (clothing
is soaked in gasoline, skin is in contact with a puddle) for a long period
(probably more than 30 minutes), serious burns and skin loss may occur.
Absorption through the skin occurs but is normally not significant.(1,8)
,
EYE CONTACT :
Irritation reported by volunteers exposed to vapour concentrations as low
as 164 ppm for 30 minutes.(7) The liquid may cause temporary pain if
splashed in the eye(s), but probably does not cause permanent damage. No
significant irritation was observed in studies with rabbits.
INGESTION :
Gasoline is moderately toxic if ingested. It may cause burning in the
mouth, throat and chest as well as stomach irritation, nausea, vomiting and


rjg> \\zinc\ehsrm_zn\public\sara title iii reports\msds for sara\gasolineunleaded2001.doc
Last printed 2/17/2001 2:30 PM
-3-


cyanosis (bluish discoloration of the fingertips, toes, lips and other
extremities). Central nervous symptom depression, such as unconsciousness
and coma, can occur. Inhalation of gasoline into the lungs (aspiration)
can occur while gasoline is in the mouth, being swallowed or during
vomiting. Aspiration often occurs when gasoline is siphoned by mouth. The
aspiration of even a small amount (less than an ounce) of gasoline into the
lungs is very hazardous and may cause death. Aspirate gasoline can cause
d
chemical pneumonitis (inflammation of the lungs) and/or pulmonary edema (a
life- threatening accumulation of fluid in the lungs).(1,11,12,13)
EFFECTS OF LONG-TERM (CHRONIC) EXPOSURE :
EFFECTS ON THE SKIN: Repeated or prolonge contact can dry the skin
d
(removes fat from skin) and cause cracking, irritation and dermatitis.
Allergic reactions (hypersensitivity) have been reported but these are rare
occurrences.(1,10)
.
EFFECTS ON THE BLOOD: There are reports of ef fects on the blood in
gasoline tanker crewmen and painters who were exposed to gasoline.(5)
These workers were probably exposed to other chemicals and therefore it is
not possible to establish a causal relationship. However, benzene is known
to cause harmful effects on the blood and may be present in gasoline in
small amounts.
.
EFFECTS ON THE PERIPHERAL NERVOUS SYSTEM: Gasoline is composed of
different paraffins (alkanes) such as n-hexane. Prolonged and/or repeated
exposure to n-hexane can cause irreversible damage to the peripheral
nervous system. Whether or not exposure to gasoline can cause this effect
depends on the presence of n- hexane and its concentration and on the
degree and duration of exposure.
.
EFFECTS ON THE NEUROLOGICAL SYSTEM: Abuse of gasoline by inhalation of the
vapours by so-called "sniffers" has resulted in many neurological effects.
Dizziness, tremor, visual and auditory hallucinations, and loss of memory
were symptoms reported in case studies of abusers who sniffed vapours
sometimes daily for years.(16,17,18) These situations are not relevant to
occupational exposures.
.
Effects on memory, intellectual capacity, psychomotor and learning ability
were seen in attendants exposed to gasoline vapours at gas stations. The
most significant effects were seen in attendants exposed for more than 5
years. Very little effect was seen in attendants with less than 1 year of
exposure.(26) The exposure concentrations wer not cited in the study.
e
Therefore, it is difficult to evaluate the results.
CARCINOGENICITY :
The available human information is inadequate for evaluation because there
is no detailed data concerning actual exposure to gasoline. Unleaded
gasoline caused kidney cancers in male rats and liver cancers in female
mice. The International Agency for Research on Cancer (IARC) concludes
that gasoline is possibly a human carcinogen (2B). Gasoline may contain
known carcinogens (e.g. benzene, ethylene dibromide).
TERATOGENICITY AND EMBRYOTOXICITY :
No human information available. No effect seen in one rat study.
REPRODUCTIVE TOXICITY :
No information suitable for evaluation. There is a Russian study of women
exposed to gasoline above the maximum permissible level which described
effects on menstrual cycle, and childbearing and lactation functions were
observed. Also, a number of newborns were malformed. The actual exposure
concentration and the length of exposure were not c ited and so this study
is not suitable for evaluation.(25)
MUTAGENICITY :
The bulk of the data indicate gasoline is not mutagenic or genotoxic.
There was a positive effect seen in one in-vivo and one in-vitro test.
TOXICOLOGICALLY SYNERGISTIC MATERIALS :
Methyl ethyl ketone or methyl isobutyl ketone enhance the action of
n-hexane. n-Hexane is one type of paraffin (alkane) found in gasoline.
POTENTIAL FOR ACCUMULATION :
Inadequate information for evaluation.

*** SECTION 4. FIRST AID MEASURES ***

INHALATION :
This product is flammable. Take proper precautions (e.g. remove any source


rjg> \\zinc\ehsrm_zn\public\sara title iii reports\msds for sara\gasolineunleaded2001.doc
Last printed 2/17/2001 2:30 PM

of ignition). 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 has stopped, trained personnel should begin artificial
respiration (AR), or, if the heart has stopped, cardiopulmonary
resuscitation (CPR) immediately. Immediately transport victim to an
emergency care facility.
SKIN CONTACT :
Avoid direct contact. Wear chemical protective clothing if necessary.
Quickly and gently blot or brush away excess chemical quickly. Wash gently
and thoroughly with water and non-abrasive soap for 5 minutes or until the
chemical is removed. Under running water, remove contaminated clothing,
shoes, and leather goods (e.g., watchbands, belts). If irritation
persists, repeat flushing. Obtain m edical advice immediately. Completely
decontaminated clothing, shoes and leather goods before re-use or discard.
EYE CONTACT :
Avoid direct contact. Wear chemical protective clothing if necessary.
Quickly and gently blot away chemical. Immediat ely flush the contaminated
eye(s) with lukewarm, gently flowing water for 5 minutes or until the
chemical is removed, while holding the eyelid(s) open. Obtain medical
advice immediately.
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 to 300 mL (8 to 10
oz.) of water. If vomiting occurs naturally, have victim lean forward to
reduce risk of aspiration. Repeat administration of water. If breathing
has stopped, trained personnel should begin artificial respiration (AR) or,
if the heart has stopped, cardiopulmonary resuscitation (CPR) immediate.
Quickly transport victim to an emergency care facility.
FIRST AID COMMENTS :
Provide general supportive measures (comfort, warmth, rest). Consult a
physician and/or the nearest Poison Control Centre for all exposures except
minor instances of inhalation or skin contact. All first aid procedures
should be periodically reviewed by a doctor familiar with the material and
its conditions of use in the workplace.

*** SECTION 5. FIRE FIGHTING MEASURES ***

FLASH POINT :
Approx. -43 deg C (-45 deg F) (19); -30 deg C (-22 deg F) (22)

257 deg C (495 deg F) (20); 280 de C (536 deg F) (22); 400 deg C (750 deg
g
F) (23)
EXPLOSION DATA - SENSITIVITY TO MECHANICAL IMPACT :
Probably not sensitive. Stable material.
EXPLOSION DATA - SENSITIVITY TO STATIC CHARGE :
Vapour can be readily ignited by static charge. Liquid can accumulate
static charge by flow or agitation.
COMBUSTION AND THERMAL DECOMPOSITION PRODUCTS :
Carbon monoxide, hydrocarbons, aromatics, oxides of nitrogen, lead and
other trace elements, phenols, polynuclear aromatic hydrocarbons.
FIRE HAZARD COMMENTS :
Extremely flammable. Material will readily ignite at room temperature.
Can release vapours that form explosive mixtures with air. Liquid can
accumulate static charge by flow or agitation. Vapour can be ignited by
static discharge. Vapour is heavier than air and may travel a considerable
distance to a source of ignition and flash back to a leak or open
container. Liquid can float on water and may travel to distant locations
and/or spread fire. During a fire, irritating/t oxic gases may be
generated. Can accumulate in confined spaces, resulting in a toxicity and
flammability hazard. Containers may explode in heat of fire.
EXTINGUISHING MEDIA :
Carbon dioxide, dry chemical, foam, water spray or fog. Water may be
ineffective, since it may not cool gasoline below its flash point.
FIRE FIGHTING INSTRUCTIONS :
Evacuate area and fight fire from a safe distance or a protected location.

Approach fire from upwind to avoid hazardous vapours and toxic
decomposition products. Stop leak before attempting to put out the fire.
If the leak cannot be stopped, and if there is no risk to the surrounding
area, let the fire burn itself out. If the flames are extinguished without
stopping the leak, vapours could form explosive mixtures with air and
reignite.
.
Isolate materials not yet involved in the fire and protect personnel.
Containers may explode in the heat of fire. Move containers from fire area
if this can be done without risk. Otherwise, keep cooling streams of water
on fire-exposed tanks or containers.
.
Water may be ineffective for fighting fires involving gasoline because of
its low flash point, unless used under favourable conditions by experienced
firefighters trained in fighting all types of flammable liquid fires.
However, water can be used on low flash point liquids when applied as a
spray to absorb heat and protect exposed material of structures. If a leak
or spill has not ignited, use water spray to disperse the vapours and to
protect personnel attempting to stop a leak. Solid streams of water may be
ineffective and spread material.
.
For a massive fire in a large area, use unmanned hose holder or monitor
nozzles. If this is not possible, wit hdraw from fire area and allow fire
to burn. Stay away from ends of tanks. Withdraw immediately in case of
rising sound from venting safety device or any discolouration of tank due
to fire.
.
Do not enter without wearing specialized protective equipment suitable for
the situation. Firefighter's normal protective clothing (Bunker Gear) will
not provide adequate protection. Chemical resistant clothing (e.g. chemical
splash suit) and positive pressure self-contained breathing apparatus
(MSHA/NIOSH approved or equivalent) may be necessary.

** NATIONAL FIRE PROTECTION ASSOCIATION (NFPA) HAZARD INDEX **

NFPA - HEALTH : 1 - Slightly hazardous to health.
NFPA - FLAMMABILITY : 3 - Can be ignited under almost all normal
temperature conditions.
NFPA - REACTIVITY : 0 - Normally stable.
NFPA - COMMENTS :
The hazard identification ratings and definitions presented here are based
on the 1985 edition of NFPA Code 704. NFPA is currently updating these
hazard ratings based on the 1990 edition of NFPA Code 704.

*** SECTION 6. ACCIDENTAL RELEASE MEASURES ***

PRECAUTIONS :
Restrict access to area. Extinguish or remove all ignition sources.
Ensure clean-up is conducted by trained personnel only. Wear adequate
personnel protective equipment. Ventilate area. Notify government
occupational health and safety and environmental authorities.
CLEAN-UP :
Do not touch spilled material. Prevent material from entering sewers,
waterways or confined spaces. Stop or reduce leak if it can be done
safely.
.
Small spills: Contain spill with earth, sand, or absorbent material which
does not react with spilled material. Do not use combustible materials
such as sawdust. Shovel into clean, dry, labelled containers and cover.
Flush area with water. Contaminated absorbent may pose the same hazards as
the spilled product.
.
Large spills: Contact fire and emergen cy services and supplier for advice.

*** SECTION 7. HANDLING AND STORAGE ***

HANDLING :
This material is an EXTREMELY FLAMMABLE LIQUID and a SUSPECTED CANCE HAZARD. Before handling it is very important that engineering contro are
ls
operated and that protective equipment requirements are being followed.
People working with this chemical should be properly trained regarding its


rjg> \\zinc\ehsrm_zn\public\sara title iii reports\msds for sara\gasolineunleaded2001.doc
Last printed 2/17/2001 2:30 PM
-6-


hazards and its safe use.
.
Eliminate all ignition sources (e.g. sparks, open flames, h surfaces).
ot
Keep away from heat. Post "NO-SMOKING" signs. It is very important to keep
areas where this material is used clear of other materials which can burn.
Use non-sparking ventilation systems, approved explosion-proof equipment
and intrinsically safe electrical systems in areas of use. Keep aisles and
exits free of obstruction. Immediately report leaks, spills or ventilation
failures. Ground all drums, transfer vessels, hoses and piping. Ground
clips must contact bare metal. When dispensing in other than a closed
system, ensure dispensing container is bonded to receiving transfer
equipment and container. Liquid can accumulate charge. In large scale
operations, increase conductivity with additive designed for tha purpose,
t
reduce flowrate in transfer operations, increase time the liquid remains in
transfer piping and/or handle at lower temperature. To prevent sparking,
generously wet hard surfaces before they are chipped, ground, etc, in
potentially hazardous areas. Never perform any welding, cutting,
soldering, drilling or other hot work onan empty vessel, container or
piping until all liquid and vapours have been cleared. Have suitable
emergency equipment for fir es, spills and leaks readily available. For
large scale operations, consider the installation of leak and fire
detection equipment along with a suitable, automatic fire suppression
system.
.
Use in smallest possible amounts in a well ventilated area separate from
the storage area. Avoid generating vapours or mists. Prevent the release
of vapours and mists into the workplace air. Do not use with incompatible
materials such as strong oxidizing agents (e.g. peroxides, nitric acid and
perchlorates). These can increase the risk of fire and explosion. Avoid
generating vapours or mists. Do not dispense in storage area unless
dispensing area is segregated by fire resistant construction. Only use
-
portable containers and dispensing equipment (faucet, pump, drip can)
approved for flammable liquids. Do not siphon by mouth. Never return
contaminated material to its original container. Label containers. Keep
containers closed when not in use. Avoid damaging containers. Empty
containers may contain hazardous residues.
.
Follow handling precautions on Material Safety Data Sheet. Practice good
housekeeping. Maintain handling equipment. Comply with applicable
regulations.
STORAGE :
Storage area should be clearly identified, well-illuminated, clear of
obstruction and accessible only to trained and authorized personnel. Store
in a cool, dry, well-ventilated area out of direct sunlight. Store away
from incompatible materials such as strong oxidizing agents (e.g.
peroxides). Follow any special instructions for storage on
supplier/manufacturer Material Safety Data Sheet (e.g. maximum storage
quantities and temperature requirements).
.
Inspect all incoming containers before storing to ensure they are undamaged
and properly labelled. Whenever possible store in original container.
Otherwise, store in sturdy containers made of compatible materials. Keep
containers tightly closed and protect from damage. Avoid stacking
containers on each other. Keep empty containers in separate area. Empty
containers can be hazardous due to residual material. Keep closed.
Provide raised sills or ramps at doorways or create a trench which drains
to a safe location. Consider leak detection and alarm equip ment for
storage area. Keep absorbents for leaks and spills readily available.
.
Store away from all heat and ignition sources. Use non -sparking
ventilation systems, approved explosion-proof equipment and intrinsically
safe electrical systems. Store according to applicable regulations for
flammable materials for storage tanks, containers, buildings, rooms,
cabinets, allowable quantities and minimum separation distances. Keep
quantity stored as small as possible. Store away from process and
production areas, away from elevators, building and room exits or main
aisles leading to exits. Keep storage area clear of other materials which
can burn. Have appropriate extinguishing capability in storage area (e.g.
sprinkler system, portable fire extinguishers).
.
Use approved explosion-proof refrigerator when storing small quantities.

Bond and ground metal containers in storage area. Avoid bulk storage
indoors. Equip storage tank vents with a flame arrestor. Stor age tanks
should be above ground over an area sealed on the bottom and diked to hold
entire contents. Store separate from work areas, eating areas and
protective equipment storage. Inspect containers and contents regularly
for leakage or expired shelf life. Eliminate all defective containers.
Have replacement containers and labels on hand. Floors should be sealed to
prevent absorbtion of this chemical.

*** SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION ***

NOTE : Exposure to this material can be controlled in many
ways. The measures appropriate for a particular
worksite depend on how this material is used and on
the extent of exposure. This general information can
be used to help develop specific control measures.
Ensure that control systems are properly designed and
maintained. Comply with occupational, environmental,
fire, and other applicable regulations.

SAMPLING AND ANALYSIS :
Use appropriate instrumentation and sampling strategy (location, timing,
duration, frequency and number of samples). Interpretation of the sampling
results is related to these variables and the analytical method. Sampling
should be performed by trained personnel.

ENGINEERING CONTROLS :
Engineering methods to control hazardous exposures are preferred. Methods
include mechanical ventilation (dilution and local exhaust), process or
personnel enclosure, control of process conditions, and process
modification (e.g., substitution of a less hazardous material).
Administrative controls and personal protective equipment may also be
required.
.
Because of the high potential fire hazard associated with this substance,
stringent control measures such as enclosure or isolation may be necessary.
Use an explosion-proof, non- sparking, grounded ventilation system separate
from other exhaust ventilation systems. Exhaust directly to the outside,
taking necessary precautions for environmental protection. Air c leaning
devices may be required. Provide sufficient local exhaust and general
(dilution) ventilation. Supply sufficient replacement air to make up for
air removed by exhaust systems.
PERSONAL PROTECTIVE EQUIPMENT :

If engineering controls and work practices are not effective in controlling
exposure to this material, then wear suitable personal protective equipment
including approved respiratory protection. Have appropriate equipment
available for use in emergencies such as spills or fire.
.
If respiratory protection is required, institute a complete respiratory
protection program including selection, fit testing, training, maintenance
and inspection. Refer to the CSA Standard Z94.4 -93, "Selection, Use and
Care of Respirators," available from the Canadian Standards Association,
