| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: WHITE CRYSTALLINE POWDER. CHEMICAL DANGERS: The substance decomposes under the influence of light and on heating to 450°C producing very toxic fumes of mercury and sulfur oxides. The solution in water is a medium strong acid. Reacts with hydrogen halides. OCCUPATIONAL EXPOSURE LIMITS: TLV (as Hg): ppm; 0.025 mg/m^3 (skin, A4) (ACGIH 1999). |
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 gastrointestinal tract and kidneys, resulting in tissue lesions and kidney damage. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the kidneys, central nervous system and peripheral nervous system, resulting in ataxia, sensory and memory disturbances, tremors, muscle weakness and kidney impairment. | ||
| PHYSICAL PROPERTIES | |||
|
Decomposes below melting point at 450°C Density: 6.5 g/cm^3 Solubility in water: reaction |
Auto-ignition temperature: >450°C | ||
| ENVIRONMENTAL DATA | |||
|
The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms. The substance may cause long-term effects in the aquatic environment.
| |||
| NOTES | |||
|
Depending on the degree of exposure, periodic medical examination is indicated. Do NOT take working clothes home.
