 · 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 apparent as

(1) Reduced consumption of explosive as blasting is more efficient due to availability of a free face for each row or round of shots e.g. blasting due to No. 1 delay detonator gives a free face for the blasting effect of shots fired by No. 2 detonator. (2) Increased fragmentation and ease of loading the rock or coal.
