Extinguishing Media:
Water, foam or dry chemical.
Special Fire Fighting Procedures:
Fight fire from upwind
position. Avoid inhalation of smoke or gases. Wear
self-contained breathing apparatus. Cool the container with
water spray.
Hazardous Combustion Products:

Also produces carbon dioxide.
Toxicological Properties _________________
Routes of Entry:
Inhalation, Ingestion, Eyes, Skin.
Effects of Acute Exposure:
Not available.
Effects of Chronic Exposure:
Not available.
In a study in rats of chronic inhalation exposure to a typical
toner, a mild to moderate degree of lung fibrosis was
observed in 92% of the rats in the high concentration
(16 mg/m
3
) exposure group. A minimal to mild degree of
lung fibrosis was observed in 22% of the rats in the middle
(4 mg/m
3
) exposure group. No pulmonary change was
reported in the lowest (1 mg/m
3
) exposure group, the most
relevant level to potential human exposures.
Exposure Limits (
ACGIH TLV
):
Inhalable Particulates: 10 mg/m
3
Respirable Particulates: 3 mg/m

Irritancy:
Not available.
Sensitivity:
Not available.
Carcinogenicity
IARC
Carbon Black:
Group 2B “Possible Carcinogen.”
This classification is given to chemicals for which there
is inadequate human evidence, but sufficient animal
evidence on which to base an opinion of
carcinogenicity. The classification is based upon the
development of lung tumors in rats receiving chronic
inhalation exposure to free carbon black at levels that
induce particle overload of the lung. Studies
performed in animal models other than rats did not
show any association between carbon black and lung
tumors. Moreover, a two-year cancer bioassay using a
typical toner preparation containing carbon black
demonstrated no association between toner exposure
and tumor development in rats.
NTP: No components are listed.
OSHA: Carbon black is designated hazardous according to
OSHA 29 CFR 1910.1200.
