IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS TO YELLOW - BROWN FLUORESCENT FLAKES OR The substance can be absorbed into the body by inhalation, through the
POWDER. skin and by ingestion.
Physical dangers Inhalation risk
Dust explosion possible if in powder or granular form, mixed with air. Evaporation at 20/C is negligible; a harmful concentration of airborne
particles can, however, be reached quickly.
Occupational exposure limits
TLV: A2 (suspected human carcinogen); (ACGIH 2004). Effects of long-term or repeated exposure
MAK: Carcinogen category: 2 (as pyrolysis product of organic materials) This substance is probably carcinogenic to humans.
(DFG 2005).
PHYSICAL PROPERTIES
Sublimation point: 435/C Solubility in water: none
Melting point: 162/C Vapour pressure, Pa at 20/C: 292
Relative density (water = 1): 1.274 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 and August 2006: see sections Occupational Exposure Limits, EU classification.
