Why are municipalities requiring Truss Identification Signs?

Buildings constructed with wood / steel trusses structurally fail significantly faster than any other means of construction in the event of a fire.  There have been many fire fighters injured and killed in fire related truss roof failures.

The number one concern for a fire fighter responding to structure fire is:  Is there a truss in the structure? and will it collapse on me?

The signs are indicators for first responders (when sizing up the emergency situation) that the building contains trusses.
