FIRE FIGHTING
FIRE Combustible.
NO open flames.
Water spray. Dry powder. 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.

EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED 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 goggles
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.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: P3 filter respirator for toxic particles. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Separated from strong oxidants, Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in seafood. It is strongly advised that this substance does not enter the environment.
N O T E S
Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. This substance does not usually occur as a pure substance but as a component of polyaromatic hydrocarbon (PAH) mixtures. Human population studies have associated PAH's exposure with cancer and cardiovascular diseases.
