What must be done to set HERO restrictions?

To set HERO (Hazards of Electromagnetic Radiation to Ordnance) restrictions, passing the word to all stations is essential. This action ensures that every personnel involved is aware of the HERO conditions and can take the necessary precautions to mitigate any potential risks associated with electromagnetic radiation and its interaction with munitions. It enables synchronized operational safety and communication across the ship or facility, minimizing the chances of accidents related to ordnance and electromagnetic interference.

Notification to the base, raising a flag, or conducting a fire drill are not direct methods to establish HERO restrictions. While these actions may be part of the broader safety and operational protocols, they do not specifically address the immediate need to inform all personnel directly involved with or affected by HERO-restricted operations. Effective communication to all stations is key to setting and maintaining proper HERO measures.
