No 2 fumes after a blast. International Society of Explosives Engineers, pp. Reduce worker exposure to blasting fumes by determining the causes of excessive blasting fumes and the toxic fumes generation of various blasting agents under different blasting conditions. Develop strategies to minimize exposure to the fumes.
All explosives generate toxic fumes when detonated.
Care must be taken to ensure that workers are protected from the fumes. To address the hazards of toxic fumes, a chamber has been constructed in which up to 10 pounds of blasting agent may be detonated and the toxic fumes confined. Blasting agent formulations typical of those employed in industry are evaluated to determine their relative fumes generation. The blasting agent is loaded in steel pipes of various wall thicknesses to simulate a variety of confinements. The blasting agent is soaked in water to simulate loading blasting agent in wet boreholes.
