PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS, OR WHITE CRYSTALLINE POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating and under influence of light. Attacks many metals .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Hg) 0.025 mg/m3 as TWA; (skin) A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2008).
MAK: skin absorption (H); sensitization of skin (Sh);
Carcinogen category: 3B; BAT issued;
(DFG 2008).


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 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 peripheral nervous system and kidneys , resulting in ataxia, sensory and memory disturbances, tremors, muscle weakness and kidney impairment.

PHYSICAL
PROPERTIES

Melting point (decomposes): 178°C
Density: 3.28
g/cm3
Solubility in water, g/100 ml at 20°C: 40

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organism. 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.
