Apr 04, 2017 · Nitric oxide (NO) and nitrogen dioxide (NO 2) are produced by large surface blasts in which the explosive does not detonate properly. NO released by the detonation oxidizes to NO 2 as the fumes mix with the atmosphere. Excessive NO 2 production is apparent as an orange cloud that forms above the blasting site. NO 2 is extremely toxic.
