SECTION 3 HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance & Odor: Light colored liquid. Aromatic hydrocarbon odor.
Health Hazards: Can cause severe lung damage and may be fatal if swallowed. May be harmful if
swallowed. May cause CNS depression.
Physical Hazards: COMBUSTIBLE. Vapors are heavier than air. Vapors may travel across the ground and
reach remote ignition sources causing a flashback fire danger.
Health Effects
Inhalation:
Irritating to respiratory system. 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. Prolonged and repeated exposures to high concentrations
may cause hearing loss (refer to 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:
May be harmful if swallowed. 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.
Eye:
Flush eyes with water while holding eyelids open. Rest eyes for 30 minutes. If redness, burning, blurred vision or
swelling persist, transport to nearest medical facility for additional treatment.
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.
Ingestion:
DO NOT induce vomiting. Have victim rinse mouth out with water, then drink sips of water to remove taste from
mouth. DO NOT GIVE LIQUIDS TO A DROWSY, CONVULSING OR UNCONSCIOUS PERSON. If vomiting
occurs spontaneously, keep head below hips to prevent aspiration. Transport to nearest medical facility for
additional treatment.
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. Refer to Section 3.

Flash Point: 111掳F / 43.89掳C
Autoignition Temperature: 864掳F / 462.22掳C
Flammability in Air: 1 - 7 %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:
COMBUSTIBLE. 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

Vapors are heavier than air. Vapors may travel across the ground and reach remote ignition sources causing a
flashback fire danger.
SECTION 6 ACCIDENTAL RELEASE MEASURES
COMBUSTIBLE. Vapors are heavier than air. Vapors may travel across the ground and reach remote ignition
sources causing a flashback fire danger.
Protective Measures:
Eliminate potential sources of ignition (no smoking, flares, sparks or flames in immediate area). Stay upwind and
keep out of low areas.
Wear appropriate personal protective equipment (refer to Section 8) when responding to spills.
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. 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.
Disposal:
Proper disposal should be evaluated based on regulatory status of this material (refer to Section 13), 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
Do not taste or swallow. 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 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. 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. Static electricity may accumulate and create a fire hazard. Bond and ground handling
equipment and transfer containers to prevent sparking.
Storage:
Keep containers closed when not in use.
Ground fixed equipment.

Skin Irritation:
Slight to moderate irritation Material Tested - Solvent Naphtha (Petroleum), Light Aromatic
Repeat Dose 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.
Carcinogenicity:
The National Toxicology Program [NTP] has reported a chronic inhalation study in rats of naphthalene, a minor
component of this product. Naphthalene caused severe inflammation and an increase in tumors of the nasal
epithelium in both sexes. NTP considered this to be clear evidence of carcinogenic activity of naphthalene in
rats. The relevance to the inhalation toxicity of this product in humans is unknown.
Reproductive and Developmental Toxicity:
Animal testing with light aromatic solvents demonstrated embryo/fetal effects but not malformations at
concentrations producing maternal toxicity.
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. Short term repeated inhalation exposure of humans to m-xylene (200 ppm or
greater) was reported to produce slight impairment of vestibular and visual function and reaction time. In these
studies, there was no evidence of cumulative effects but some evidence of tolerance or adaptation. Repeated
inhalation studies with some similar solvents or components in animals have reported decreased activity typical of
central nervous system depression, but no irreversible effects.
Other Information:
Animal data suggest that slight anemia, adaptive liver changes, and kidney toxicity (male rat nephropathy) may
be caused by repeated over exposure to some similar solvents. The significance of this to humans is unknown.
