  prevent backdraft and allow for fire growth
• Shortly thereafter the room flashed over and
  front thermo pane glass doors self vented.
• FIT 5 was activated and thrown in
• The following pictures start with the device
  being thrown in.

OBSERVATIONS

• Due to the lack of confinement the agent was able
  to escape and oxygen was able to be re-introduced
  into the fire room. Thus the fire did eventually
  grow back to its original intensity.
• It seems logical that if the room was unvented
  the agent would have been confined and thus the
  fire re-growth would not have occurred or would
  have at least been significantly delayed.
