11. Toxicology and Health Hazards
Routes Of Overexposure: Eye, skin, inhalation, and oral
Acute Health Hazards:
• Overexposure of eye surface to toner may be mildly irritating
• Overexposure of skin to toner contact may cause irritation and in some people swelling and redness
• Intentional or accidental inhalation overexposure to toner may result in respiratory tract irritation
• Intentional or accidental oral ingestion may cause an upset stomach
Chronic Health Hazards:
Use of this product, as intended, does not result in inhalation of fugitive excessive dust. In an
inhalation study with rats chronically exposed to a typical developer, a mild to moderate degree
of lung fibrosis was observed in approximately 90% of rats in the high concentration exposure group
(16mg/cubic meter), and a minimal to mid degree of fibrosis was noted in approximately 20% of the
animal in the middle exposure group (4mg/cubic meter). But no pulmonary change was reported in
the lowest exposure group (1mg/cubic meter), the most relevant level to potential human
exposure.
Carcinogenicity:
With excessive exposure, carbon black has been listed as a possible human carcinogen.
However, as engineered within this toner cartridge, emissions to air of carbon black
during normal printing use have not been found. IARC, the International Agency for
Research on Cancer, has found printing toners to be not classifiable as human
carcinogens.
