Important Data
|
Physical State; Appearance:
COLOURLESS
CRYSTALS OR
WHITE
,
HYGROSCOPIC
POWDER.
Physical Dangers:
Chemical Dangers:
Shock-sensitive compounds are formed with phosphinic acid, ethanol and acetylene.
The substance is a strong oxidant and reacts violently with combustible and reducing materials.
The substance decomposes
under influence of
light
.
Occupational Exposure Limits:
TLV: (as mercury) 0.025 mg/m3 as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued (ACGIH 2008).
MAK: (as Hg) 0.1 mg/m3
Peak limitation category: II(8);
sensitization of skin (Sh);
Carcinogen category: 3B; BAT issued;
(DFG 2008).
|
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
when dispersed
.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes
the skin and
the respiratory tract.
Corrosive on ingestion.
The substance may cause effects on the
kidneys
.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
The substance may have effects on the
central nervous system,
kidneys
and
peripheral nervous system
, resulting in ataxia, sensory and memory disturbances, fatigue, muscle weakness and
kidney impairment
.

Solubility in water:
good
|
|
Environmental
Data
|
The substance is very toxic to aquatic organisms.
In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms.
It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
|
|
N O T E S
|
Depending on the degree of exposure, periodic medical examination is indicated.
Do NOT take working clothes home.
