OSHA HCS Classification

According to the criteria in OSHA HCS (2012) 29 CFR 1910.1200 for classifying hazardous sub- stances, Carbon Black is not classified for any toxicological or eco-toxicological endpoint. As a combustible dust it is designated by OSHA as a hazardous chemical. Not a dangerous substance or mixture according to the Globally Harmonised System (GHS). According to the criteria in GHS (UN) for classifying hazardous substances, Carbon Black is not classified for any physico-chemical, toxicological or eco-toxicological endpoint.

Warning

Precautionary statements

May form explosible dust-air mixture if dispersed. Keep away from all ignition sources including heat, sparks and flame. Prevent dust accumulations to minimize explosion hazard. Control dust exposures to below applicable occupational expo- sure limits.

2.3 Other hazards

A solid, black, odourless, insoluble, substance that can burn or smoulder at temperatures greater than 752ºF (400ºC, VDI 2263). Hazardous products of decomposition can include carbon monoxide, carbon dioxide, and oxides of sulphur. May cause reversible mechanical irritation to the eyes and respiratory tract, especially at concen- trations above the occupational exposure limit. Some grades of carbon black are sufficiently electrically non-conductive to allow a build-up of static charge during handling. Take measures to prevent the build-up of electrostatic charge. Inhalation Temporary discomfort to upper respiratory tract may occur due to mechanical irritation when ex- posures are above the occupational exposure limit. Skin contact May cause mechanical irritation, soiling, and skin drying. No cases of sensitization in humans have been reported. Eye contact High dust concentrations may cause mechanical irritation to eye. . Long-term exposure below the current occupational exposure limit of 3.5 mg/m3 (when measured as traditional total dust) may result in a small loss in one aspect of lung function (FEV1) over a working life-time. IARC listed: Group 2B (possibly carcinogenic to humans). Not listed as a carcinogen by NTP, ACGIH, OSHA, or the European Union. See Section 11. However, the manufacturers of carbon black state that epidemiologic studies of workers in the carbon black industry in the U.S. and W. Europe show no significant adverse health effects due to occupational exposure. This product contains one or more ingredients that have been shown to produce mutagenic effects in in vitro testing. Some studies have linked exposure of carbon black dust to lung effects. . Most carbon blacks contain trace quantities of PAHs present at levels less than 0.1% unless oth- erwise specified by the supplier. There are no known human carcinogenic effects related to the PAH content of carbon blacks. Recent research has shown that the PAH content of carbon blacks is not released in biological fluids and thus not available for biological activity. See Section 16.
