Plain-language answer: ICS 213 is a general message form used within the Incident Command System to record and route concise official messages.
Why it matters
The form gives a message structure; it does not decide priority, authorization, routing, privacy, or whether radio is the correct transport.
Use it well
Record sender, recipient, subject, date/time, message, approvals, and reply accurately, then follow the served agency’s routing and retention procedure.
The common mistake
Rewriting or paraphrasing message content instead of preserving the authorized text.
Authority and safety boundary
Current regulations, electrical codes, equipment manuals, program authorization, and the served organization’s procedures control. This article is practical orientation, not permission to transmit, alter protective wiring, or self-deploy.
