HERO hazards relate to what type of hazard?

• A. Fire hazard
• B. Electromagnetic radiation to ordnance
• C. Chemical hazard
• D. Mechanical hazard

Answer: (B)

HERO hazards come from electromagnetic radiation affecting ordnance. In this context, some munitions can be sensitive to radio-frequency energy, so RF fields from transmitters, antennas, radar, or other high-power electronic sources can couple into initiators or arming circuits and cause unintended detonation or arming. This risk is specific to the interaction between electromagnetic energy and ordnance, not simply general fire, chemical, or mechanical hazards. So the key idea is that HERO concerns the potential for RF energy to trigger or influence ordnance, requiring separation from RF sources and proper safe handling procedures to prevent initiation.
