I have written about his subject several times. It has been debated, argued, revisited and gone through the whole hay bailer again. Much like everything we do, there are several different ways to accomplish the same mission. A majority of them fall in the realm of not wrong but different. To me the “when to mask up question” is one of those topics. As I have stated before there is a few wrong places to mask up (In the hot zone, or near potential exhaust points) but for the most part it is up to personal preference.
You can argue one way or the other, but if you take this video for wha it is worth, and at face value then the only way this rescue could have been made is by coming off the rig masked up. Taking the time to mask up in the yard would have taken too much time and the room would have flashed over before an entry could have been made.
This technique does work, and when practiced can decrease our Zero Impact Period.
Like I have said a million times however this needs to be trained on here is an example[youtube http://www.youtube.com/watch?v=HDi5L1Cco8I]
People who participate in the Firefighter Combat Challenge do so in full PPE,SCBA, with mask on air. These events are supposed to mirror the fireground, all it takes is training. You think it will affect your size up, then practice your size up with your mask on. You think it will affect your fireground movement, then put your mask on and do the movements.
It is possible, and with training you can make it happen.
As usual thanks for reading, spread the word, and STAY SAFE!
