Excellent video - glad everyone made it out safe. Brings up a question of how would this fire have been different if PPA was used instead of PPV? We are just delving into possibly using PPA interested in hearing some feedback on it.
John Kriska is one of the pre-eminent PPV/PPA instructors.
He teaches proper and safe application.
And he has been doing it for many years.
Monitor the exhaust point!
PPV is a great tool for the tool box. But, it must be used with caution as demonstrated in the video. Coordination with the attack team and an adequate exhaust point are critical. During PPV training you must test and practice using PPV so it can be used effectively during real incidents.
There are also some new practices that should be utilized. In the past we have been taught that we must "cone" the entire doorway. But, we have now learned we should leave 4 to 6" at the top of the door not in the coned space. This will help the IC monitor conditions and monitor the effectiveness of the exhaust port. If the exhaust port is too small and becomes blocked, clogged or closed off you will have smoke and heat push out above the coned area. When an exhaust port becomes blocked the heat and fire will be pushed to other areas. The IC must be aware of where it’s being pushed and if that changes!
PPV is not a "set it and forget it" tactic! It must be monitored closely.
