TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible.

Water spray, powder. In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

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, face shield or eye protection in combination with breathing protection.
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.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: complete protective clothing including self-contained breathing apparatus.

BENZ(a)ANTHRACENE ICSC: 0385
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW-BROWN FLUORESCENT FLAKES OR POWDER.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: A2 (suspected human carcinogen); (ACGIH 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is probably carcinogenic to humans.
PHYSICAL PROPERTIES
Sublimation point: 435C
Melting point: 162C
Relative density (water = 1): 1.274
Solubility in water: none
Vapour pressure, Pa at 20C: 292
Octanol/water partition coefficient as log Pow: 5.61
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur in seafood.
NOTES
This substance is one of many polycyclic aromatic hydrocarbons - standards are usually established for them as mixtures, e.g., coal tar pitch volatiles. However, it may be encountered as a laboratory chemical in its pure form. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Do NOT take working clothes home. Tetraphene is a common name. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification.
