Section 4. Hazardous Identification (Emergency Overview)
Toner is a fine, black powder possessing no immediate hazard. There are no anticipated carcinogenic effects
from exposure based on animal tests performed using toner. When used as intended according to instructions,
studies do not indicate any symptoms of fibrosis will occur.

Carcinogenicity : In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen (possible human carcinogen).
This classification is given to chemicals for which there is inadequate humanevidence, but sufficient ani-
mal evidence on which to base an opinion of carcinogenicity. Theclassification is based upon the devel-
opment of lung tumors in rats receiving chronic inhalationexposures to free carbon black at levels that
induce particle overload of the lung. Studiesperformed 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.
Chronic Effect : Prolonged inhalation of excessive dust may cause lung damage. It is attributed to “lung overloading”, a
generic response to excessive amounts of any dust retained in the lungs for a prolonged interval. Use of
this product as intended does result in inhalation of excessive dust. In a study in rats by chronic inhala-
tion exposure to a typical toner, a mild to moderate degree of lung fibrosis was observed in 92% of rats
in the high concentration (16mg/m
3
) exposure group, and a minimal to mild degree of fibrosis was
noted in 22% of the animals in the middle (4mg/m
3
) exposure group. But no pulmonary change was
reported in the lowest (1mg/m
3
) exposure group, the most relevant level to potential human exposures.
