Section 4. Hazardous Identification (Emergency Overview)

Developer is a black powder containing small amounts of toner, and possessing no immediate hazard. There are no anticipated carcinogenic effects from exposure based on animal tests performed using toner.

Section 5. Health Hazard Data

Route(s) of Entry:	Inhalation?	Skin?	Ingestion?
	No	No	Possible but very unusual.
Health Hazards:	Acute oral toxicity ------------ LDL0 of this toner which is included in this developer is over
		2,000mg/kg.
	Mutagenicity ------------------ The toner, which is included in this developer, has been tested on
		Ames test. The result 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.

While there have been no studies to date using developer, a two-year cancer bioassay using a typical toner preparation containing carbon black (a small amount of toner is included in the developer mixture) demonstrated no association between toner exposure and tumor development in rats.

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.
