EXPLOSION EXPOSURE AVOID ALL CONTACT!  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles, 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. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Provision to contain effluent from fire extinguishing. Well closed.

International Chemical Safety Cards BENZO(k)FLUORANTHENE ICSC: 0721 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: Upon heating, toxic fumes are formed. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and through the skin. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is possibly carcinogenic to humans. PHYSICAL PROPERTIES Boiling point: 480°C Melting point: 217°C Solubility in water: none Octanol/water partition coefficient as log Pow: 6.84 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to air and water. In the food chain important to humans, bioaccumulation takes place, specifically in crustacea and fish. N O T E S Benzo(k)fluoranthene is present as a component of polycyclic aromatic hydrocarbons (PAH) content in the environment usually resulting from the incomplete combustion or pyrolysis of organic matters, especially fossil fuels and tobacco. ACGIH recommends environment containing benzo(k)fluoranthene should be evaluated in terms of the TLV-TWA for coal tar pitch volatile, as benzene soluble 0.2 mg/m3. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. ADDITIONAL INFORMATION ICSC: 0721 BENZO(k)FLUORANTHENE (C) IPCS, CEC, 1994
