According to best practices, how long should radio broadcasts last?

The recommended duration for radio broadcasts is no longer than 30 seconds. This guideline is based on the understanding that shorter transmissions are more effective for clarity and retention among listeners. In the high-pressure environment of public safety communications, concise messages ensure that critical information is conveyed quickly and reduces the risk of misunderstandings or missed details.

Longer broadcasts can lead to information overload, making it difficult for recipients to retain important information and respond appropriately. By adhering to a 30-second limit, telecommunicators maintain the capacity to relay essential details efficiently while ensuring that the information is straightforward and easy to comprehend during emergency situations.
