Emergency Information (US and Canada only): call
1-800-654-3282.
Emergency First Aid Procedures
Toner swallowed (ingested).
Rinse out mouth with water and give several glasses of
water to drink. Seek medical attention.
Toner inhaled.
Remove person to fresh air. Rinse mouth with water.
Toner gets in the eyes.
Flush eyes with large quantities of cool water for 15
minutes, keeping the eyelids open with fingers. Seek
medical attention.
Toner gets on the skin.
Wash toner off the skin with plenty of cool water and soap.
Note: Small amounts of toner on skin or clothing can
easily be removed with soap and cold water.
Hot water makes toner harder to remove.

Special Fire Fighting Procedures: In case of fire, use
extinguishing media. When mounted in the printer, treat as
an electrical fire.
Hazardous Combustion Products: Not applicable
Toxicological Properties
Routes of Entry: Inhalation, Ingestion, Eyes, Skin
Effects of Acute Exposure (based on toxicity data for
similar materials and ingredients):
Swallowed LD50 (rat): > 5.0 g/kg
Skin LD50 (rabbit): > 5.0 g/kg
Inhaled LC50 (rat): > 5 mg/L/4hr
Effects of Chronic Exposure (based on toxicity data for
similar materials and ingredients): The results obtained
from a sponsored, Chronic Toner Inhalation Study,
demonstrated no lung change in rats for the lowest (1 mg/
m3) exposure level (i.e. the level most relevant to
potential human exposure).
A very slight degree of fibrosis was noted in 25% of the
animals at the middle (4 mg/m3) exposure level, while a
slight degree of fibrosis was noted in all the animals at the
highest (16 mg/m3) exposure level.
These findings are attributed to "lung overloading," a
generic response to excessive amounts of any dust
retained in the lungs for a prolonged period. This study
was conducted using a special test toner to comply with
EPA testing protocol. The test toner was ten times more
respirable than commercially available Oki toner, and
would not be functionally suitable for Oki equipment.
Exposure Limits, ACGIH TLV†:
Total: 10 mg/m3
Respirable: 3 mg/m3
Irritancy: Not an irritant.†
Sensitization (skin, guinea pig): Not a sensitizer.†
Carcinogenicity: Not classified as “Carcinogens”

IARC: Refer to IARC Monographs on the Evaluation
Carcinogenic Risks to Humans (WHO International
Agency for Research on cancer).
NTP: Refer to National Toxicology Program (NTP)
Report on Carcinogens (NTP).
