Which feature is crucial for ensuring safety during operations involving HERO?

The crucial feature for ensuring safety during operations involving HERO (Hazards of Electromagnetic Radiation to Ordnance) is proper ordnance handling protocols. HERO relates specifically to the risks posed by electromagnetic radiation to ordnance, which can lead to inadvertent detonation. Adhering to proper handling protocols includes ensuring that ordnance is stored, transported, and manipulated in a way that minimizes exposure to harmful electromagnetic fields. This can involve using shielding techniques, implementing safe distances, and following specific procedures during operations to safely manage the risks associated with electromagnetic radiation interference.

Routine maintenance checks can support safety but do not directly address HERO-related hazards. Visibility conditions and strict personnel limitations may enhance overall operational safety but are not specifically linked to the dangers posed by electromagnetic radiation to ordnance. Thus, proper ordnance handling protocols remain the key factor in mitigating risks associated with HERO.
