Important Data
|
Physical State; Appearance:
COLOURLESS
HYGROSCOPIC
CRYSTALS.
Physical Dangers:
Chemical Dangers:

on heating
or
on burning
producing toxic and
irritating fumes
including
nitrogen oxides
,
phosphorus oxides
.
Attacks iron, steel, brass.
Occupational Exposure Limits:
TLV: (as vapour and aerosol)
(Inhalable fraction)
0.05 mg/m3 as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
MAK not established.
OSHA PEL: none
NIOSH REL: TWA 0.25 mg/m3
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
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
,
respiratory failure
.
Cholinesterase inhibitor.
Exposure may result in death.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.

Environmental
Data
|
The substance is very toxic to aquatic organisms.
This substance may be hazardous to the environment; special attention should be given to honey bees, birds, mammals.
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.

N O T E S
|
Depending on the degree of exposure, periodic medical examination is suggested.
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 solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
Azodrin, Bilobran, Crisodrin, Monocron, Nuvacron, Plantdrin, Susvin are trade names.
