In the video Patrick Durham (StacheD on Youtube) refers to a 330ft Hot Zone. This is the 100m Standard Isolation Distance
Specified by the U.S. Dot Emergency Response Guide. This Hot Zone is the responders best guess at the initial perimeter of the
Area around an incident that requires full AIR (SCBA) and PPE (protective gear). In other words where to keep out unprotected
Personnel. There may also be a Warm Zone (contamination reduction zone) and a Cold Zone (safe area for command, staging,
And vehicles.) The Cold Zone might be the same as the temporary 2-mile evacuation area that was ordered around recent BESS fires.
