SECTION 3 HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance & Odor: Colorless liquid. Hydrocarbon odor.
Health Hazards: Can cause severe lung damage and may be fatal if swallowed. May cause CNS depression.
Physical Hazards: EXTREMELY FLAMMABLE. Vapors are heavier than air. Vapors may travel across the
ground and reach remote ignition sources causing a flashback fire danger.
Inhalation:
Breathing of high vapor concentrations may cause central nervous system (CNS) depression resulting in
dizziness, light-headedness, headache, nausea and loss of coordination. Continued inhalation may result in
unconsciousness and death. Vapors expected to be slightly irritating. Prolonged and repeated exposures to high
concentrations may cause hearing loss (see section 11). Chronic hydrocarbon abuse (for example, sniffing glue
or light hydrocarbons such as contained in this material) has been associated with irregular heart rhythms and
potential cardiac arrest.
Eye Contact:
May cause temporary discomfort or irritation to the eye.
Skin Contact:
May be slightly irritating to the skin. Prolonged or repeated skin contact can cause defatting and drying of the skin
which may result in a burning sensation and a dried, cracked appearance.

Ingestion:
Liquid can directly enter the lungs (aspiration) when swallowed or vomited. Serious lung damage and possibly
fatal chemical pneumonia (chemical pneumonitis) can develop if this occurs.
Primary Target Organs:
The following organs and/or organ systems may be damaged by overexposure to this material.
Heart, Auditory System
SECTION 4 FIRST AID MEASURES
Inhalation:
Move victim to fresh air. If the victim has difficulty breathing or tightness of the chest, is dizzy, vomiting or
unresponsive, give 100% oxygen with rescue breathing or CPR as required and transport to the nearest medical
facility.
Skin:
Wipe off excess material from exposed area. Flush exposed area with water and follow by washing with soap if
available. If redness, swelling, pain and/or blisters occur, transport to the nearest medical facility for additional
treatment.
Eye:
Flush eyes with water while holding eyelids open. Rest eyes for 30 minutes. If redness, burning, blurred vision or
swelling persist, consult a physician.
Ingestion:
DO NOT induce vomiting. Have victim rinse mouth out with water, then drink sips of water to remove taste from
mouth. In general no treatment is necessary unless large quantities are swallowed, however, get medical
advice. If the victim is coughing, choking, has shortness of breath, or difficulty breathing, transport to the nearest
medical facility for additional treatment. If any of the following delayed signs and symptoms appear within the
next 6 hours, transport to the nearest medical facility: fever greater than 101潞 F, shortness of breath, chest
congestion or continued coughing or wheezing. If vomiting occurs spontaneously, keep head below hips to
prevent aspiration.
Note to Physician:
Light hydrocarbons like this one have been associated with cardiac sensitization in abuse situations. Hypoxia or
the injection of adrenaline-like substances enhances these effects.
SECTION 5 FIRE FIGHTING MEASURES
Flash Point [Method]: <10 潞F/< -12.22 潞C [ Tagliabue Closed Cup]
Autoignition Temperature: 500 潞F/260 潞C
Flammability in Air: 1 - 8 %volume
Extinguishing Media:
Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames. Do not use a direct stream of
water. Material will float and can be re-ignited on surface of water.
Fire Fighting Instructions:
EXTREMELY FLAMMABLE. Clear fire area of all non-emergency personnel. Do not enter confined fire space
without full bunker gear (helmet with face shield, bunker coats, gloves and rubber boots), including a positive
pressure, NIOSH approved, self-contained breathing apparatus. Containers exposed to intense heat from fires
should be cooled with large quantities of water to prevent weakening of container structure which could result in
container rupture.
Unusual Fire Hazards:
Vapors are flammable and heavier than air. Vapors may travel across the ground and reach remote ignition

sources causing a flashback fire danger.
SECTION 6 ACCIDENTAL RELEASE MEASURES
EXTREMELY FLAMMABLE. Vapors are flammable and heavier than air. Vapors may travel across the ground
and reach remote ignition sources causing a flashback fire danger.
Protective Measures:
Isolate hazard area and deny entry to unnecessary or unprotected personnel. Eliminate potential sources of
ignition (no smoking, flares, sparks or flames in immediate area). Stay upwind and keep out of low
areas. Handling equipment must be bonded and grounded to prevent sparking.
Wear appropriate personal protective equipment when responding to spills. Refer to Section 8.
Spill Management:
Shut off source of leak if safe to do so. Dike and contain spill. Use water spray (fog) to reduce vapors or divert
vapor cloud drift. If vapor cloud forms, use water fog to suppress or blanket spill area with foam. Remove with
vacuum trucks or pump to storage/salvage vessels. Soak up residue with an absorbent such as clay, sand or
other suitable material and dispose of properly. Flush area with water to remove trace residue. Contain run-off
from residue flush and dispose of properly. Prevent entry into waterways, sewer, basements or confined
areas. Remove contaminated soil to remove contaminated trace residues. Dispose of in same manner as
material. For small spills: Soak up residue with an absorbent such as clay, sand or other suitable material. Place
in non-leaking container and seal tightly for proper disposal.
Proper disposal should be evaluated based on regulatory status of this material (see Section 15), potential
contamination from subsequent use and spillage, and regulations governing disposal in the local area.
Reporting:
This material is covered by EPA's Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA) Petroleum Exclusion. Therefore, releases to the environment may not be reportable under
CERCLA. Notify authorities if any exposures to the general public or environment occurs or is likely to occur.
SECTION 7 HANDLING AND STORAGE
Avoid contact with eyes, skin and clothing. Avoid prolonged or repeated contact with eyes, skin and
clothing. Wash thoroughly after handling.
Handling:
Surfaces that are sufficiently hot may ignite liquid material. Vapors are flammable and heavier than air. Vapors
may travel across the ground and reach remote ignition sources causing a flashback fire danger.
Keep away from heat, sparks and flame. Extinguish pilot lights, cigarettes and turn off other sources of ignition
prior to use and until all vapors have dissipated. Use explosion-proof ventilation to prevent vapor accumulation
while in use. Properly dispose of any contaminated rags or cleaning materials in order to prevent fires. Wash
with soap and water before eating, drinking, smoking, applying cosmetics, or using toilet facilities. Launder
contaminated clothing before reuse. Air-dry contaminated clothing in a well-ventilated area before
laundering. Bond and ground handling equipment and transfer containers to prevent sparking.
Storage:
Keep containers closed when not in use.
Container Warnings:
Containers, even those that have been emptied, can contain explosive vapors. Do not cut, drill, grind, weld or
perform similar operations on or near containers.

SECTION 11 TOXICOLOGICAL INFORMATION
Acute Toxicity
Hydrocarbon Solvent Inhalation - LC50 15,000 ppm (v) (Rat) 4 hour(s)
Solvent Naphtha, Light Aliphatic Dermal - LD50 >2.84 g/kg (Rat)
Solvent Naphtha, Light Aliphatic Oral - LD50 >7.1 g/kg (Rat)
Eye Irritation:
minimal irritation [Rabbit] Material Tested - Solvent Naphtha, Light Aliphatic
Skin Irritation:
slight irritation [Rabbit, 24 hour(s)] Material Tested - Solvent Naphtha, Light Aliphatic
Subchronic Testing:
While there is no evidence that industrially acceptable levels of light hydrocarbon vapors (e.g., the occupational
exposure limit) have produced cardiac effects in humans, animal studies have shown that inhalation of high levels
produced cardiac sensitization. Such sensitization may cause fatal changes in heart rhythms, which was shown
to be enhanced by hypoxia or the injection of adrenaline-like substances.
Neurotoxicity:
Prolonged and repeated exposures to high concentrations of some volatile hydrocarbon solvents have resulted in
hearing loss in rats. Solvent abusers and noise interaction with these solvents in the work environment may
cause symptoms of hearing loss.
Other Testing:
Kidney effects in male rats were observed in laboratory animals exposed to a similar material. Effects were
consistent with male rat hyaline droplet nephropathy which is of questionable significance to human health.
Mutagenicity:
Some effects to chromosomes but no mutagenic effects were observed in genotoxicity studies conducted for
similar hydrocarbon solvent mixtures. The biological significance of the chromosomal findings is unknown.
