Description:"Six different types of blasting caps, mainly of the type used in coal mines, were evaluated to determine both their radio frequency and direct current characteristics. Two of the caps were of foreign manufacture. All of the American made caps had "no-fire" (0.1 pct firing probability with 95 pct confidence, as determined by the Bruceton test) levels above 0.04 Watts. One of the caps of foreign manufacture had a "no-fire" level of 0.023 watts. A worst case analysis of blasting cap pickup of radio frequency power in coal mines was performed, and safe distance curves were generated." - NIOSHTIC-2
