SECTION 2: Hazards identification

Emergency Overview: Black powder with a slight odor. Carbon black has been classified as an IARC 2B (possible human) carcinogen. May cause respiratory tract or skin irritation. May form flammable or explosive dust-air mixtures. Avoid chronic pulmonary exposures to dust. Avoid exposure to eyes, skin or clothing (will stain). Keep container closed. Use with adequate ventilation. Physical Description: Sealed cartridge contains black powdery solid material, with slight odor.

Physical hazards

As with most finely divided dusts, an explosion in possible when an extremely high concentration of dust and an ignition source are present. Not a hazard under normal conditions of use.

Principle Routes of Exposure

Inhalation of dust, skin contact

Potential health effects

Skin: Short Term Exposure: Testing and/or information on this or similar toners, or on the constituents of this toner indicate this toner is not a skin irritant and is of low dermal toxicity. Toner is not a dermal sensitizer. Long Term Exposure: Rare individuals may note skin rash with repeated contact. Exposure is not probable with intended use. Eye: Short Term Exposure: Toner may act as a mechanical irritant. Long Term Exposure: No adverse chronic effects known. Exposure is not probable with intended use. Inhalation: Short Term Exposure: Testing and/or information on this or similar toners, or on the constituents of this toner indicate low inhalation toxicity. As with exposure to high concentrations of any dust, minimal respiratory tract irritation may occur if excessive amounts of toner dust are inhaled. Exposure is not probable with intended use. Long Term Exposure: No adverse chronic effects known at intended level of use. Respirable size particles may collect in lungs and show up on X- rays (iron oxide). No adverse changes in the lungs result from this accumulation. Exposure is not probable with intended use. Ingestion: Short Term Exposure: Testing and/or information on this or similar toners, or on the constituents of this toner indicate low oral toxicity. Exposure is not probable with intended use. Long Term Exposure: No adverse chronic effects known. Exposure is not probable with intended use. Conditions Aggravated by Exposure: None known at intended levels of use. Signs and Symptoms of Exposure: Large amounts of toner on skin or mucous membranes (mouth, eyes, or nose) may cause discomfort. Carcinogen Status: OSHA: N IARC: Y (Carbon black) NTP: N ACGIH: N
