Give victim oxygen and keep under observation. If exposure was severe, watch victim for 24-48 hours.

Not combustible, but upon decomposition or contact with acids, this material releases highly flammable and toxic hydrogen cyanide gas. Also hydrolyzes in water to release hydrogen cyanide.
Violent explosion occurs if melted with nitrite salt.
