IMPORTANT DATA
Physical State; Appearance Routes of exposure
ODOURLESS, BLACK PELLETS OR EXTREMELY FINE The substance can be absorbed into the body by inhalation of its
POWDER. aerosol and by ingestion.
Physical dangers Inhalation risk
Dust clouds can be ignited on contact with intensely heated Evaporation at 20/C is negligible; a nuisance-causing
surfaces (above 500/C). concentration of airborne particles can, however, be reached
quickly.
Chemical dangers
Effects of long-term or repeated exposure
On combustion, forms highly toxic carbon monoxide (see ICSC
0023). Reacts with strong oxidants such as chlorates, bromates Lungs may be affected by repeated or prolonged exposure at very
and nitrates. high concentrations (see Notes).
Occupational exposure limits
TLV: 3.5 mg/m 3 as TWA; A4 (not classifiable as a human
carcinogen); (ACGIH 2004).
MAK: (Inhalable fraction) Carcinogen category: 3B; (DFG 2004).
PHYSICAL PROPERTIES
Melting point: ca. 3550/C Solubility in water: none
Relative density (water = 1): 1.8-2.1
ENVIRONMENTAL DATA
NOTES
Some carbon blacks may contain compounds which are carcinogenic and as organic extracts of these have been classified as possibly
carcinogenic to humans, special care should be taken to avoid exposure to such extracts.
Lung effects remain controversial and may be due to contaminants. It is probable that minor effects reported are non-specific effects
associated with exposure to nuisance dusts in general.
Polyaromatic hydrocarbons (PAH) are reportedly present in some carbon blacks. Depending on the process of manufacture, there are
variations in their chemical compositions.
Carbon blacks containing over 8% volatiles may pose an explosion hazard (see Physical Dangers). Carbon black of mineral origin has
no UN number and hazard classification.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
