Hazard Predictions

Corrosive: Reaction products may be corrosive
Generates heat: Exothermic reaction at ambient temperatures (releases heat)

Thiosulfates are reduced to corrosive metal sulfides and sulfites by metallic copper, zinc, or aluminum (Bean, S. L. 2000. Thiosulfates. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)). Alkali metals may react in a similar way.
