FIRE FIGHTING
FIRE

In case of fire in the surroundings: use appropriate extinguishing media.
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. Store in an area without drain or sewer access.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Upon heating, toxic fumes are formed.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: skin absorption (H);
Carcinogen category: 2; Germ cell mutagen group: 3A
(DFG 2007).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and through the skin.

INHALATION RISK:
Evaporation at 20C 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: 480C
Melting point: 217C
Solubility in water:
none
Octanol/water partition coefficient as log Pow: 6.84
ENVIRONMENTAL
DATA
Environmental Hazard placard This substance may be hazardous to the environment; special attention should be given to air quality and water quality. Bioaccumulation of this chemical may occur in crustacea and in 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 environments containing benzo(k)fluoranthene should be evaluated in terms of the TLV-TWA for coal tar pitch volatile, as benzene soluble 0.2 mg/m. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
