|PHYSICAL STATE; APPEARANCE: |
COLOURLESS TO WHITE CRYSTALS.
The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride and sulfur oxides .
OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 mg/m3 as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
OSHA PEL†: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH IDLH: 500 mg/m3 See: 136787
|ROUTES OF EXPOSURE: |
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the kidneys and liver .
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
|Melting point (decomposes): 245°C |
Relative density (water = 1): 1.70
|Solubility in water, g/100 ml at 25°C: (good) |
Vapour pressure, Pa at 20°C: 133
| 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. |
