International Chemical Safety Cards CARBON BLACK ICSC: 0471 CARBON BLACK C Atomic mass: 12.01 CAS # 1333-86-4 RTECS # FF5800000 ICSC # 0471 UN # 1361 (carbon, animal or vegetable origin) TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. NO contact with hot surfaces. Powder, water spray, foam, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention. SKIN Protective gloves. Rinse and then wash skin with water and soap. EYES Safety goggles or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Rest. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from strong oxidants. UN Hazard Class: 4.2 SEE IMPORTANT INFORMATION ON BACK ICSC: 0471 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities © IPCS CEC 1993

International Chemical Safety Cards CARBON BLACK ICSC: 0471 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS, BLACK PELLETS OR EXTREMELY FINE POWDER. PHYSICAL DANGERS: Dust clouds can be ignited on contact with intensely heated surfaces (above 500°C). CHEMICAL DANGERS: On combustion, forms highly toxic carbon monoxide (see ICSC # 0023). Reacts with strong oxidizers such as chlorates, bromates and nitrates. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 3.5 mg/m3 (ACGIH 1994-1995). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure at very high concentrations (see Notes). PHYSICAL PROPERTIES Melting point: ca. 3550°C Relative density (water = 1): 1.8-2.1 Solubility in water: none

ENVIRONMENTAL DATA
N O T E S
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.
