CHLORFENVINPHOS ICSC: 1305
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
ORANGE TO BROWN LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic and corrosive fumes of hydrogen chloride, see - ICSC0163 and phosphorus oxides. Attacks tin, brass, iron and steel.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the the nervous system, resulting in convulsions and respiratory failure. Cholinesterase inhibitor. Exposure may result in unconsciousness and death. The effects may be delayed (see Notes). Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
PHYSICAL PROPERTIES
Boiling point at 0.07kPa: 167-170C
Melting point: -19 to -23C
Relative density (water = 1): 1.36
Solubility in water: none
Vapour pressure, Pa at 20C: <0.001 (0.53 mPa)
Octanol/water partition coefficient as log Pow: 3.82
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of acute intoxication do not become manifest until 30 minutes to 6-12 hours. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Birlane, Dermaton, Sapecron, Steladone, Supona are trade names.
Card has been partly updated in April 2005. See section Emergency Response.
