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 ------- LDL0 of this toner is over 2,000mg/kg.
	Mutagenicity ------------- The result of Ames test is negative.
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 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
	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 concentration (16mg/m3) exposure

group, and a minimal to mild degree of fibrosis was noted in 22% of the animals in the middle (4mg/m3) exposure group, but no pulmonary change was reported in the lowest (1mg/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

Emergency and First Aid Procedures:

Inhalation;	Remove to fresh air. If effects occur, consult medical personnel.
Eye;	In case of contact, immediately flush eyes with water for 15 minutes.
