Important Data
|
Physical State; Appearance:
COLOURLESS
TO WHITE
CRYSTALS.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
or
on burning
producing toxic and
irritating fumes
including
nitrogen oxides
,
phosphorus oxides
,
sulfur oxides
.
Attacks copper.
Occupational Exposure Limits:
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.

Environmental
Data
|
The substance is very toxic to aquatic organisms.
This substance may be hazardous to the environment; special attention should be given to its persistence in soil.
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.

N O T E S
|
|
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 solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Betamec, Betasan, Disan, Exporsan, Prefar, Pre-san are trade names.
Card has been partly updated in October 2005. See section EU classification.
