All emergency communications—regardless of the medium—should conform to general principles of effective communication.

In a crisis, clarity, specificity, and consistency are vitally important. Be sure to:

• Present the information in sequence. Present the reason for the message, the supporting information, and the conclusion.
• Word the message precisely, making every word count.
• Avoid jargon, codes, and acronyms.
• Use common terminology for all personnel and facilities.
• Omit unnecessary details.
• Speak in sync with other related authorities.
• Keep messages consistent across various media.
