Disaster strikes one hour from now.
What do you do?
Who do you call?
Who is your Block Leader? Area Leader?
CERT came about in the 70s after massive wildfires ravaged most of California. When leaders looked back to figure out what they could have done differently, they learned the information never got from the Officials leading the operation to the homeowners.
CERT is about organizing information.
A Block Leader checks on the houses in their assigned territory (usually their side of the street), reports to an Team Leader, who reports to an Area Leader, who reports to the "City" officals handling the emergency. And communications flows back down the same way.
Reach out. Find out who is directing your communication in the event of an emergency.
