Got my CERT training in Culver City. It's affiliated with our Fire Dept and has 4 days of training plus a full day practical test as a graduation requirement. After that, you get the ID.
In some areas, CERT will get called out in conjunction with local Red Cross to handle triage and the like. There was a callout after a train derailment a few years back, as an example.
Good people who care about their community.
