Current through Register No. 40, October 3, 2024
(a) The sensitivity of the blasting agent shall be determined by means of a No. 8 test blasting cap at regular intervals and after every change in formulation.
(b) Oxidizers of small particle size, such as crushed ammonium nitrate prills or fines, might be more sensitive than coarser products and shall, therefore, be handled with greater care.
(c) No hydrocarbon liquid fuel with flash point lower than that of No. 2 diesel fuel oil, 125SYMBOL 176 \f "Symbol" F minimum or legal, shall be used.
(d) Crude oil and crankcase oil shall not be used as an explosive component because they might contain light ends that offer increased vapor-explosions hazards or gritty particles that tend to sensitize the resulting blasting agent.
(e) Metal powders such as aluminum shall be kept dry and shall be stored in containers or bins which are moisture-resistant or weather-tight. Solid fuels shall be used in such manner as to minimize dust explosion hazards.
(f) Peroxides and chlorates shall not be used as an explosive component.
