Which energy source may cause unintentional ignition of explosive initiating devices (EIDs)?

• A. Heat
• B. Radio frequency
• C. Friction
• D. Electric arc

Answer: (B)

Radio frequency energy can cause unintentional ignition of explosive initiating devices by coupling into the initiator circuitry or into sensitive explosive materials. When RF fields from transmitting equipment, radios, or radar are present, they can induce currents or voltages in the initiation path or nearby conductors, producing a brief energy release that can trigger the device even without direct contact or a visible spark. This makes RF a distinct ignition hazard for EIDs, because it works through electromagnetic energy transfer rather than just heat, friction, or a direct electric arc. Keep RF-emitting gear separated from initiating devices and use proper shielding and separation to prevent this risk.
