Storage and handling
Carbon black should be stored in a clean, dry, uncontaminated area away from exposure to high temperatures, open flame sources and strong oxidizers (e.g., chlorates, bromates, and nitrates). Since carbon black will adsorb moisture and chemical vapors, it should be stored in closed containers.
Spill clean-up and general housekeeping are very important for controlling carbon black exposures. Carbon black dust spreads easily in air through virtually any air current or movement. Additionally, because carbon black is a pigment, it may stain exposed surfaces. Housekeeping procedures that avoid the production of dust or generation of fugitive emissions in the process are highly recommended. Dry vacuuming, with appropriate filtration, is the preferred method for removing surface dust and cleaning spills. Dry sweeping should be avoided. Bulk carbon black should always be covered or contained. Care should be taken to avoid generating conditions that may result in unnecessary exposure.
Acute First Aid
There is no evidence to suggest that acute exposure to carbon black may result in life threatening injury or illness. Carbon black is not a respiratory irritant, as defined by the Occupational Safety and Health Administration (OSHA), and does not produce respiratory or dermal sensitization. Ingestion is an unlikely method of accidental exposure. Like many dusts, inhalation may initiate a bronchial response among individuals with pre-existing lung conditions.
Inhalation: Short-term exposures to elevated concentrations may produce temporary discomfort to the upper respiratory tract, which may result in coughing and wheezing. Removal from carbon black exposure is normally sufficient to cause symptoms to subside without lasting effects.
Skin: Carbon black dust or powder may cause drying of the skin with repeated and prolonged contact. Skin drying may also result from frequent washing of carbon black contaminated skin. Carbon black may be washed from the skin using mild soap and water along with gentle scrubbing action. A waterless skin cleaner may also be used. Repeat washing may be necessary to remove carbon black. A protective barrier cream on exposed skin surfaces may also be an effective method for minimizing dermal exposure.
Ingestion: No adverse effects are expected from carbon black ingestion. Do not induce vomiting.
Eye: Carbon black is not a chemical irritant. Treat symptomatically for mechanical irritation. Rinse eyes thoroughly with water to remove dust. If irritation persists or symptoms develop, seek medical attention.
