Electromagnetic Radiation Threat to Electrexplosive Devices

DOE-HDBK-1092-2004

3. Filter, or provide ferrite beads for, signal lines from the equipment which may conduct EMR

emissions into EED circuitry or secondarily radiate EMR in the proximity of an EED thus

causing a threat of detonation.

4. Ensure that the minimal power necessary is used to operate circuitry capable of producing

EMR.

5. Label the equipment capable of emitting EMR to indicate the minimum separation distance

to be maintained between the equipment and an EED or EEDs.

6. Use a safety factor in design for EMR reduction; e.g., only 1/10 of the energy that would

initiate an EED is allowed.
