Explosive reaction in excess. Explosive with impact. When heated above room temperature, explosvie chlorine dioxide is evolved. May liberate oxygen and heat explosively. Fire and explosion hazard.
Ruthenium is insoluble in aqua regia, but addition of potasisum chlorate causes explosive oxidation.
Violent reaction may occur when heated. May explode upon heating. Impact-sensitive, explosive mixture. Explodes with heat, percussion, and sometimes light friction. Fire and explosion hazard.
