IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALS OR POWDER.

Chemical dangers
On contact with hot surfaces or flames this substance decomposes forming corrosive fumes of sulfur oxides. The solution in water is a medium strong acid. The substance is a strong reducing agent and reacts violently with oxidants powdered metals, nitrates, nitrites and heavy metal salts.

Occupational exposure limits
TLV not established.

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
The substance is irritating to the eyes and the skin. The substance may cause effects on the blood, resulting in the formation of methaemoglobin.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood, resulting in anaemia.
