If the EID is incapable of being initiated by EMR in its expected EME, either by design or shielding, the EID shall be classified as ______.

Explanation:
HERO safe. The key idea is whether electromagnetic energy could unintentionally trigger the initiating device in its expected electromagnetic environment. If the EID cannot be initiated by EMR in that environment—whether because of the design preventing initiation paths or shielding blocking the energy—it is considered HERO safe. This means there’s no hazard of unintended initiation from electromagnetic radiation under normal conditions. If initiation were possible, or if data were uncertain, other HERO classifications would apply.
