What should you not do if someone telephones in a bomb threat?

When someone telephones in a bomb threat, hanging up the phone is not a recommended action because it can prevent valuable information from being obtained. Instead, it is crucial to remain on the line to gather as much information as possible about the threat. This includes asking for details about the location of the bomb, the time it is set to detonate, and any other specifics the caller may provide. Remaining calm and listening attentively allows the person receiving the call to document important elements of the situation, which can be vital for law enforcement and emergency responders.

Notifying the authorities immediately is also essential, but this should be done after gathering pertinent information while still conversing with the caller to enhance the response. Each piece of information could be critical in assessing the seriousness of the threat and how best to respond. Therefore, the best practice is to remain engaged and attentive, rather than cutting communication abruptly.
