Current through Register Vol. 56, No. 18, September 16, 2024

(a) The provisions of this section shall be considered when determining blasting agent compositions.

(b) The sensitivity of the blasting agent shall be determined by means of a No. 8 blasting cap at regular intervals after every change in formulation, or as may be required by the Commissioner.

(c) Oxidizers of small particle size, such as crushed ammonium nitrate prills or fines, may be more sensitive than coarser products and shall be handled with greater care.

(d) No hydrocarbon liquid fuel with flash point lower than that of No. 2 fuel oil (125 degrees F minimum or legal) shall be used.

(e) Crude oil and crankcase oil shall not be used because they may contain light ends that offer increased vapor-explosion hazards or gritty particles that tend to sensitize the resulting blasting agent.

(f) Peroxides and chlorates shall not be used.

(g) 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 to minimize dust explosion hazards.

(h) The provisions of (d), (e) and (f) above shall not apply to compositions made under the supervision of a qualified person engaged in research and development capable of determining the overall hazard of the resulting product in its manufacture, storage, or use.
