LPG Fires: Sometimes it’s about perspective

 

LPG

 

HMN-Recently, at an industrial fire training, I got some great helmet cam footage of some very experienced firefighters honing in on new skills, and brushing up on old ones.  I was able to capture a great shot that illustrates the effect of nozzle patterns, and draft, on a LPG fire.

In the following photo, take note of the size of the cone and the fire being drawn into the center.  We always like to harp on moving a hose line in unison as hose handling training before drills like this, but we also need to be aware of the nozzle patterns and their potential impact on fire, or vapor streams.

The photo has a great depiction of the wide pattern beginning to draft vapors toward the nozzle.
The guys in the photo did an amazing job and this is just a small snippet in time of their advancing and successful, safe isolation of this prop.

 

Great Job!

  1. Our very first “Live fire” training scenario was doing valve isolation at recruits – I was on the branch (which had its own unique character – coneing in and out was a challenge but manageable once I worked it out) – capturing the flame – absolutely loved it! – Got roasted in the de-brief about my “responsiveness” until I informed him about the branch (as they get abused so much on campus – the branches that is – recruits – maybe not enough lol). One of the only times in the job where tunnel vision is encouraged!
