CDC Mining Topic Blasting and Explosives NIOSH

Apr 04, 2017 What is the health and safety problem? Detonating explosives release toxic gases, primarily oxides of nitrogen and carbon monoxide. 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
