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.

Section 5. Health Hazard Data

Route(s) of Entry : Inhalation? Skin? Ingestion?
Yes No Possible but very unusual.
Health Hazards : Acute oral toxicity—LD50 of this toner is over 2,000m /k .
Mutagenicity—The result of Ames test is negative.
Carcinogenicity : In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen (possi-
ble human 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 carcinogenic-
ity. The classification is based upon the development of lung tumors in rats receiving chronic
inhalation exposures 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.
Chronic Effect : 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 con centration
(16m /m3) exposure group, and a minimal to mild degree of fibrosis was noted in 22% of the
animals in the middle (4m /m3) exposure group, but no pulmonary change was reported i n
the lowest (1m /m3) exposure group, the most relevant level to potential human exposures.
Signs and Symptoms of Exposure : Minimal irritation to respiratory tract may occur as with exposure
to any non-toxic dust.
Medical Conditions Generally Aggravated by Exposure : None
