Final answer:
The instruction that is not one of the rules for handling an explosive device on an active shooter scene is 'communicate the device'. Standard procedures emphasize not touching the device, turning off communication devices, and creating safe distance, but communication about the device typically follows specific protocols.
Step-by-step explanation:
The instruction that IS NOT one of the three rules when dealing with an explosive device on an active shooter scene is communicate the device. The standard procedures usually include not touching the device, turning off your radio and cell phone to prevent any unintended detonation due to radio signals, and creating distance with angles and air gaps to minimize the blast impact and protect oneself. Communicating about the device typically involves specific protocols and is not about the physical interaction with the device itself.It is crucial to understand that certain electronic devices should be turned off near potential explosive devices because mobile phones and similar communication devices can emit signals that might trigger detonation. This also aligns with protocols in sensitive environments such as hospitals or airplanes, where mobile phones are required to be switched off or in a non-communicative mode to avoid interference with critical equipment.
