Section 11: Toxicological Information
Toxicology Information
Oral toxicity: Almost non-toxic. LD 50: > 2000 mg/kg (species: rats)
Dermal toxicity: Almost non-toxic. LD 50: > 2000 mg/kg (species: rabbits)
Inhalation toxicity: Almost non-toxic. LD 50: > 5 mg/l (species: rats)
Eye irritation: Almost non-irritating. Draize score: > 6 and < 15 (species: rabbits)
Skin irritation: Irritant. Primary irritation index: > 3 and < 5 (species: rabbits)
Other data: Inhalation of high concentrations of vapors or mists may cause
respiratory system irritation and damage. It may also result in the
damage and depression of the central nervous system and may
cause death. Prolonged contact with the material may cause
severe skin irritation.
Subchronic toxicity: Dermal studies resulted in significant irritation but not systematic
toxicity (species: rabbits). Inhalation exposures (90 day,
approximately 1500 ppm vapor) produced light hydrocarbon
nephropathy but no significant systemic toxicity (species: rats).
Neurotoxicity: Repeated and prolonged exposures to high concentrations of
vapor has been reported to result in central nervous system
damage and eventually, death. In a study in which ten human
volunteers were exposed for 30 minutes to approximately 200,
500 or 1000 ppm concentrations of gasoline vapor, irritation of the
eyes was the only significant effect observed, based on both
subjective and objective assessments.
However, no persistent neurotoxic effects were observed in
subchronic inhalation studies of gasoline.
Reproductive toxicity: An inhalation study with rats exposed to 0, 400 and 1600 ppm of
wholly vaporized unleaded gasoline, 6 hours per day on day 6
through 16 of gestation, showed no teratogenic effects nor
indication of toxicity to either the mother or the fetus. Another
inhalation study in rats exposed to 3000, 6000, or 9000 ppm of
gasoline vapor, 6 hours per day on day 6 through 20 of gestation,
also showed no teratogenic effects nor indications of toxicity to
either the mother or the fetus.
Chronic toxicity: A lifetime mouse skin painting study of unleaded gasoline applied
at 50 microliters, three time weekly, resulted in some severe skin
irritation and changes, but no statistically significant increase in
skin cancer or cancer to any other organ. Lifetime inhalation of
wholly vaporized unleaded gasoline over 2000 ppm has caused
increased liver tumors in female mice and increased kidney
tumors in male rats. The EPA has concluded that mechanism by
which wholly vaporzied unleaded gasoline causes kidney damage
is unque to the male rat. The effects in that species (kidney
damage and cancer) should not be used in human risk

on humans Very hazardous in case of eye contact.
Hazardous in case of skin contact.
Slightly hazardous in case of inhalation.
Carcinogenic effects: Contains material that may cause cancer depending on the level
and duration of exposure.
Target organs: Contains material that may cause damage to humans organs such
as (but not limited to) blood, kidneys, lungs, liver, eye, skin,
nervous system and upper respiratory tract.
Section 12: Ecological Information
Ecotoxicity: This material may be toxic to aquatic organisms such as algae
and daphnia. It has also shown to be toxic to fish.
Environmental fate: The material is expected to be readily biodegradable. When
released into the environment, some of the constituents of
gasoline will volatilize and be photo degraded in the atmosphere.
Following spillage, the more volatile components of gasoline will
be rapidly lost, with concurrent dissolution of these and other
constituents into the water. Factors such as local environmental
conditions, photo-oxidation, biodegradation and adsorption onto
suspended sediments, can contribute to the weathering of spilled
Section 13: Disposal Considerations
Waste disposal: Avoid disposal of spilled material and runoff and contact with soil,
waterways, drains and sewers. Disposal of this product and any of
its by products should always comply with the requirements of
environmental protection and waste disposal legislation and any
local authority requirements.
This material would likely be identified as a federally regulated
RCRA hazardous waste. See sections 7 and 8 for further
information on handling, storage and personal protection. See
