Upon discovering a bomb device, what should members avoid using within one block of the device?

When a bomb device is discovered, it is critical to avoid using radio transmitters or cell phones within one block of the device due to the risk of triggering an explosion. Many explosive devices are designed to be activated remotely, often responding to radio frequencies or signals emitted by electronic devices, including those used in cellular communications.

Using radio transmitters or cell phones may inadvertently send a signal that could detonate the bomb, putting individuals in the vicinity at great risk. This precaution highlights the importance of maintaining a safe distance and minimizing any potential interference that could lead to an unintended detonation.

Other methods of communication or signaling, such as hand signals or flashing lights, do not carry the same risk of electronic interference, and emergency sirens, while potentially alarming, are typically not linked to triggering explosive devices. Therefore, the emphasis on avoiding the use of radio equipment in the vicinity of a bomb is a vital safety measure in bomb threat scenarios.
