Its been along time since I masked up. I keep seeing comments about yard breathing. I remember turning on the bottles in the engine, grabbing a line and going in. (yes we did check doors and windows and signs for backdrafts)

 

Is the new school to turn on the air at the door? And if you have a 30 min bottle, how long to you plan on being inside?

That from the guy who tried to label a single-word reply as "immature". Makes you go "hmmmmm".

As for turning your head in a mask - you still have limited peripheral vision - just in different directions.
Yea, things change, usually for the better.
I make the connection just before I enter the structure unless the circumstances dictate that I be on air beforehand. I want every second of air that I can get before I have to come outside to swap out.

I had a call (well, calls) a number of years ago during a thunderstorm where we were enroute to a structure fire during a severe thunderstorm with reported flames showing. First in arrived, confirmed fire showing so we figured we were going to be working. One of my backseaters went on air just before we arrived at the call. We get there....first in engine crew made one hell of a knock, assisted by an actual firewall in the attic of the residence (turns out the home used to belong to a Fire Marshall in a nearby city and he insisted on rated firewalls in the attic) so we arrived to a fire that was out and after about 5 minutes on scene got redirected to another nearby structure fire. We arrived first in on that one with heavy smoke showing so we made entry. Literally 5' in the door the one backseater's bells went off, cutting my interior crew from 3 to 2. We took a beating until the 2nd due engine arrived. From that point on I have always stressed to my folks that we don't go on air until we have to.
Lots of replies for one simple rule. Don't breath smoke! If you are where the smoke is breath your air.
The good ole days of riding tailboard. At least the sunny and dry days were good. Rain and snow sucked.

Never had the wall-mounted SCBA's though. Other than spares anyways.

If I'm last in the truck, I just throw my belt on and grab my pack when dismounting. Anyone else who threw their's on before hand never seem to be waiting for me when it's time to go.

Probably makes for far more comfortable seats as well. Our last engine that we got, the seats are terribly uncomfortable.
Don it, check it, then come off air until you need it.

You did your PMCS at the beginning of your shift, and after the last time you used it during the shift, then you go on air for a single breath at the engine when you don it, then come off air until at the door, or inside depending on conditions, like NOVA said.

Use 1/3 inside the structure, 1/3 for getting out, 1/3 for safety...
So, realistically, you have 4-5 minutes inside a structure?

Assuming you've ever timed yourself while being on air and working hard; pulling ceilings, hauling hose, etc.
I have not heard the term "yard breathing" with my department. What is it?
Being "on air" when it isn't required. Jumping off a truck and running to the door. Standing around the structure in clear air. Climbing any number of flights of stairs before getting close to the fire floor.

Basically wasting air in a non-IDLH situation.
Thank you.
hell, some crewchiefs wont even mask up until they get to the door, the will have the guys pull the line get to the door and then mask up and go on air, save energy but not time....
