2. Composition Information
Toner is a moist powdered formulation
3. Hazard Identification
3.1 Emergency Overview: Toner is a moist yellow powder that may cause eye irritation. Avoid contact with
eyes or clothing. In the case of skin contact, wash with soap and water. Keep out of reach
of children.
3.2 Potential Health Effects:
Eyes: Toner contact with eye may be mildly irritating. See Section 11 for Toxicology.
Skin: Toner contact with skin may cause irritation, swelling, or redness. It is not expected to cause an allergic skin
reaction. See Section 11 for Toxicology.

Inhalation: Intentional exposure to toner may cause respiratory irritation. See Section 11 for Toxicology.
Ingestion: May cause upset stomach. See Section 11 for Toxicology.
4. First Aid Measures
4.1 Eyes: Immediately flush with room temperature, low pressure, clean water for at least 15 minutes. Seek medical
attention if eye irritation continues.
4.2 Skin: Wash surface areas with soap and water. Wash soiled clothing before re-wearing. Seek medical attention if
irritation continues.
4.3 Inhalation: Remove subject to ventilated fresh air and rinse mouth. Consult physician if necessary or if cough
develops.
4.4 Ingestion: Rinse mouth with water. Seek medical attention if stomach continues to be upset.
5. Fire Fighting Measures
Flammability: Flash point is greater than 230 deg. F / 110 deg. C (closed cup in accordance with ASTM D3278)
Extinguishing Media: Dry chemical or carbon dioxide
Fire Fighting Instructions: Breathing apparatus required. No special explosive hazards are known.
6. Accidental Release Measures
Shut off ignition sources. If a spill occurs, use sponges to wipe-up toner, then rinse area with damp cloth. Place
waste in closed container for disposal. Use proper ventilation. Do not dispose of waste to the sewer. No eye or skin
protection required during clean-up. Wash hands with soap and water.
7. Precautions for Safe Handling and Use
Keep out of reach of children and do not dismantle or incinerate cartridge. Keep cartridge in dark, cool, dry, and well
ventilated are. Do not store cartridges with oxidizing agents. Make sure cartridge is dry before insertion into printer
housing. Avoid dispersing toner.

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 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 has not been found. IARC, the
International Agency for Research on Cancer, has found printing toners to be not
classifiable as human carcinogens.
Titanium dioxide is classified as “possibly carcinogenic to humans” (Group 2B). In
animal chronic inhalation studies, the tumor formulation observed in only rats with
animal chronic inhalation 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 not result in inhalation of excessive dust.
Epidemiological studies to date have not revealed any evidence of the relation
between exposure to titanium dioxide and diseases of the respiratory tract beyond
the general effects of dust.
