PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS.
CHEMICAL DANGERS:
The substance decomposes
on heating or
on burning
producing toxic and irritating fumes including nitrogen oxides, phosphorous oxides, sulfur oxides.
Attacks copper.
OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
|
ROUTES OF EXPOSURE:
The substance can be absorbed into the body
by inhalation of its aerosol,
through the skin and
by ingestion.
INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the nervous system
, resulting in convulsions and respiratory failure.
Cholinesterase inhibitor.
Exposure may result in death.
The effects may be delayed.
Medical observation is indicated.
See Notes.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
See Notes.

|
No specific data on health hazard of this compound were available but many organophosphates are cholinesterase inhibitors (for instance, see ICSC # 0172 on Malathion).
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.
Betamec, Betasan, Disan, Exporsan, Prefar, Pre-san are trade names.
