Lifetime skin painting studies in animals with products similar to Heavy catalytic cracked distillate, No. 6 fuel oil and/or its
components have produced tumors in animals following prolonged and repeated skin contact. Repeated dermal
application has produced severe irritation and systemic toxicity in subacute toxicity studies.
Summary of health effect data on residual fuel oil components:
This product contains diesel fuel (middle distillate) at a level of >1.0% Lifetime skin painting studies in animals with
similar distillate fuels have produced weak to moderate carcinogenic activity following prolonged and repeated exposure.
Similar middle distillates, when tested at nonirritating dose levels, did not show any significant carcinogenic activity
indicating that this tumorigenic response is likely related to chronic irritation and not to dose. Repeated dermal application
has produced severe irritation and systemic toxicity in subacute toxicity studies.
This product may contain >0.1% naphthalene. Exposure to naphthalene at 30 ppm for two years caused lung tumors in
female mice. Male mice with the same exposure did not develop tumors. Exposure to 10-60 ppm naphthalene for 2 years
caused tumors in the tissue lining of the nose and respiratory tract in male and female rats. Certain groups or
individuals, i.e., infants, Semites, Arabs, Asians and Blacks, with a certain blood enzyme deficiency (glucose-6-phosphate
dehydrogenase) are particularly susceptible to hemolytic agents and can rapidly develop hemolytic anemia and systemic
poisoning from ingestion or inhalation of naphthalene.
Catalytic cracked clarified oil (CCCO) may be present in concentrations up to 100% in this product. Lifetime skin painting
studies in animals with CCCO have produced tumors in animals following prolonged and repeated skin contact.
Repeated dermal application of CCCO (30 mg/kg/day for 13 weeks) in rats resulted in anemia, liver degeneration and
injury to bone marrow and lymphoid tissues. 100% mortality was observed at 2,000 mg/kg/day within three weeks.
Repeated dermal application (30 mg/kg/day) of CCCO to pregnant rats during gestation produced maternal and fetal
toxicity, some deaths and systemic toxicity (liver, thymus and blood). The number of viable offspring decreased at doses
of 30 mg/kg/day and above. Many of the developmental effects (anomalies, resorptions and growth inhibition) were
observed at doses which produced maternal toxicity. In a separate developmental study CCCO produced decreases in
body weights and food consumption at doses from 10-250 mg/kg/day. Although fertility and reproductive function were
not affected, the no observable adverse effect level for CCCO administered dermally was 1 mg/kg/day.
This product contains >0.1% 3-7 ring polynuclear aromatic hydrocarbons (PAC's). Some PAH's such as
benzo(a)phenanthrene and 5-methylchrysene have been shown to be carcinogenic in experimental animals. An
increased risk of cancer has been observed in workers employed in the aluminum production, coal gasification, coal-tar
pitch, coke production and iron and steel industries that had been occupationally exposed to polynuclear aromatic
hydrocarbons (PAC). Since these kinds of PACs have been measured at high levels in air samples taken in these
idustries, IARC has concluded that these PACs are probably carcinogenic to humans.
Hydrogen sulfide gas (H2S) is toxic by inhalation. Prolonged breathing of 50-100 ppm H2S vapors can produce eye and
respiratory tract irritation. Higher concentrations (250-600 ppm) for 15-30 minutes can produce headache, dizziness,
nervousness, nausea and pulmonary edema or bronchial pneumonia. Concentrations of >1000 ppm will cause immediate
unconsciousness and death through respiratory paralysis. Rats and mice exposed to 80 ppm H2S, 6 hrs/day, 5
days/week for 10 weeks, did not produce any toxicity except for irritation of nasal passages. H2S did not affect
reproduction and development (birth defects or neurotoxicity) in rats exposed to concentrations of 75-80 ppm or 150 ppm
H2S, respectively. Over the years a number of acute cases of H2S poisonings have been reported. Complete and rapid
recovery is the general rule. However, if the exposure was sufficiently intense and sustained causing cerebral hypoxia
(lack of oxygen to the brain), neurologic effects such as amnesia, intention tremors or brain damage are possible.
12. ECOLOGICAL INFORMATION
Ecotoxicity effects: Product can be toxic to fish and aquatic life. The 24 hour TLM of the water soluble

Additional Information: The pronounced and easily-recognized rotten egg odor of hydrogen sulfide gas
(H2S) can be detected at concentrations as low as 0.003-0.13 ppm. Since higher
H2S concentrations (100-200 ppm) cause olfactory fatigue and other hydrocarbon
odors can "mask" H2S, the sense of smell cannot be used as a reliable indicator of
H2S exposure.
