Which materials are listed as explosive agents?

• A. Coal and wood dust
• B. Water and air
• C. ANFO, Prill
• D. Sand and gravel

Answer: (C)

Explosive agents are substances designed to undergo a rapid energetic reaction to produce a blast. ANFO (ammonium nitrate/fuel oil) is one of the most common blasting agents used in mining and construction, delivering a powerful explosion when initiated. Prill refers to ammonium nitrate in prilled form, which is used as the nitrate component in blasting formulations. These are intentionally energetic materials designed for explosive effects. Coal and wood dust can form hazardous explosive atmospheres when suspended in air, but they are not typical explosive agents themselves. Water and air do not act as explosive materials, and sand and gravel are inert fillers.
