CA OES/FEMA Marking System

This week I’d like to go over the FEMA marking system for buildings, searches and victims. Building markings should be made by structural engineers so it’s not something the average person should be putting on to a building, however, knowing what the markings mean will aid you during an emergency situation. The marking system I’ll be reviewing here is the CA OES/FEMA marking system which is very slightly different from the federal FEMA marking system but close enough – and since I’m in California that’s the system I know. Knowing these markings will aid you during a disaster if you are seeking shelter or aiding in search and rescue.

Building Markings are always done where they can be easily seen from the front of the building and not necessarily at the front entrance. The marker will use arrows to point to the safest entry point into the structure or safe haven. The markers must be two feet by two feet so you can see them from a good distance. Building markings look like this:

A building labeled Good will have cosmetic damage, there could be debris without structural damage and the utilities are probably still functional.

A building labeled with a single slash signifies that it has problems and evidence of structural damage. This could mean cracks around the foundation, door and window frames and other structural damage which could need bracing or shoring up. It is a structure which you need to access the risk versus reward to entering the building – get in, do what you need to do and get out because if there is an aftershock the structure may fall.

A box with an X means this structure is in bad shape, it could fall and has structural failure. Do not enter a structure such as this.

Main Entrance Markings start with a single slash /. Later when the search is completed the slash will become an X. Knowing this, at the top of the slash the date and time of search is written, on the left of the X is what team checked it. On the right of the X is what was found I.E. chemicals, etc. At the bottom of the X is if there were victims found.  Screen Shot 2016-04-08 at 11.18.15 AM

The X marking system is also used at the entrance to each room or apartment within a building. This way search and rescue teams know which interior rooms have been checked allowing them to pass and know not to waste time on places that have already been checked.

The last important markings are for Victims, there are four marks. If there is a victim trapped under debris and the initial search team is waiting for a recovery team the team will mark the wall with a V and an arrow pointing to the location of the victim. A V with a circle around it means the victim is alive. A victim (V) with a circle around it ( O ) and a single slash ( / ) means the victim is known to be deceased. When the recovery team removes the body they will then create another slash through the circled V creating an X. Screen Shot 2016-04-08 at 11.25.12 AM
