International Chemical Safety Cards BENZO(g,h,i)FLUORANTHENE ICSC: 0527 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes. 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: EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: See Notes. PHYSICAL PROPERTIES Melting point: 149°C Solubility in water: none Vapour pressure, Pa at 20°C: <10 Relative vapour density (air = 1): 7.8 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Octanol/water partition coefficient as log Pow: 7.23 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to the total environment. In the food chain important to humans, bioaccumulation takes place, specifically in oils and fats. N O T E S Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Also consult ICSC #0720 and 0721.
