Chemical Safety
0585 TRICHLORPHON
IMPORTANT DATA
Physical State; Appearance Routes of exposure
WHITE CRYSTALS The substance can be absorbed into the body by inhalation of its
aerosol, through the skin and by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on heating and on contact with acids
and bases producing toxic fumes. Attacks many metals. Evaporation at 20/C is negligible; a harmful concentration of
airborne particles can, however, be reached quickly on dust
Occupational exposure limits forming.
TLV: (Inhalable fraction) 1 mg/m 3 as TWA; A4 (not classifiable as
Effects of short-term exposure
a human carcinogen); BEI issued; (ACGIH 2004).
MAK not established. The substance may cause effects on the nervous system by a
cholinesterase inhibiting effect, resulting in convulsions,
respiratory failure, and death. Cholinesterase inhibitor. Exposure
at high level may result in death. The effects may be delayed.
Medical observation is indicated.
Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The
substance may have effects on the nervous system.
Cholinesterase inhibitor; cumulative effect is possible: see acute
hazards/symptoms.
PHYSICAL PROPERTIES
Melting point: 83-84/C Vapour pressure, Pa at 20/C: < 0.01
Relative density (water = 1): 1.73 Octanol/water partition coefficient as log Pow: 0.48
Solubility in water, g/100 ml at 25/C: 15.4
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance may be hazardous in the environment; special attention should be
given to honey bees and fish.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of acute intoxication do not become manifest until some hours have passed.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The recommendations on this card apply to the pure form. Commercial formulations are often mixtures including impurities, solvent or
other agents which modify toxic and physicochemical properties.
Acrol, DEP, DANEX, DIMETOX are trade names.
Card has been partly updated in October 2004 and 2005. See sections Occupational Exposure Limits, EU classification, Emergency
Response.
