Which energy source may cause unintentional ignition of EIDs?

• A. Heat
• B. Radio frequency
• C. Magnetic field
• D. Friction

Answer: (B)

Radio frequency energy can cause unintentional ignition of EIDs because RF fields can couple into the initiator’s electrical circuitry and deliver a rapid energy pulse that reaches the initiation threshold, even without any direct contact or visible sparks. This means devices emitting or carrying RF signals—such as radios, cell phones, radar, or other wireless equipment—can inadvertently trigger an initiating device if it’s nearby or not properly shielded. To reduce risk, keep EIDs away from RF-emitting gear, use proper shielding, and maintain safe separation or de-energize equipment as needed. While heat, friction, and magnetic fields can pose ignition risks under certain conditions, RF energy uniquely poses a remote initiation threat by coupling into circuits and causing an ignition event without physical interaction.
