Where firefighters come to talk training

I keep reading how departments insist on using 13/4 lines for Standpipe operations. Usually the set up includes a gated Wye, so a second line can also be stretched to supplement the lower GPM's. How many departments have ever trained on a tandem attack. If anyone is interested in learning more about how to do this leave your information on the comment page. A video on this topic will be available early next year.

My department currently uses 150' of 1.75" with a low pressure fog (175gpm @ 75psi) and 2.5" to 1.75" gated wye in our stand pipe pack. I would like to see some modifications to this, but have been meeting resistance (the old, we have always done it this way bit, or it's too heavy) The low pressure fog is pumpable for us, our highest hazard is 5 stories, and the 75 psi helps the kinks down (as opposed to 50 psi smoothbore) since we are short staffed. I would like to see your tandem op, anything to help improve our operations would be great.

Be safe. You'll be here all week.

Hey Bro,
Yeah, we have trained on this some since your class, but we too are still using the gated wye, (2) 1 3/4" lines and fog tips. We are making progress through flow test and actual achievable flows in our standpipe buildings that are proving that we are not capable of getting adequate flows on upper floors. Still trying to get our highrise packs switched to 2 1/2". Send me the video info and BE SAFE BRO!!!!!!

I'm interested in the tandem attack video. We use 6' pony section of 2 1/2 to gated wye with 150' of 1 3/4 with fog nozzles. Would like to change to 2" with snooth tip. Any thoughts?

Ray, I'd love to have a copy of the video,

Ray-I am looking foreward to the video.

Russ - As you know some departments will not change and that is the reason for the training video. At standpipe operations where 1 3/4 hose will be used and the two lines pressed into service departments need to drill on how to effectively advance and operate the lines in an efficient manner. I have taught the tandem attack technique at many fire academies including the FDTN and it is a technique many have never seen before.

We still run a 6' three inch pony line with a gated wye, then 3 lengths of 1 3/4" with a SB with a 15/16" tip. All this much to my chagrin, as we have talked about proper standpipe kits before. The one situation I want to tell you is we were flowing in a city housing project. I had one of my personal inline gauges on the outlet. I had a pitot gauge on the roof, with the first hoseline attached to the top floor standpipe outlet. My ECC had to pump up to 180 PSI to give me 50 psi at the tip of the nozzle. We then connected up to the other side of the wye with the "backup" hoseline. When that hoseline opened up, we had the expected pressure loss, and the ECC had to throttle back up. When this occured, the inline gauge was only at 110 PSI, and the pitot gauge was only at 30 PSI when the Control FF radioed, or I should say screamed to shut everything down. What had happened was the 3" pony line let go at the pressure ring around the coupling. We cleaned up the mess, had a good laugh about it, but then afterword it hit me like a ton of bricks the ramafactions if this were a real fire. In other words, this system puts all of our eggs in one basket. We lost both the initial attack hoseline, PLUS the backup hoseline. If it were the type of fire where we had to use a tandem attack, (EWD) we would have hurt some guys. So now, until we switch to the 2 1/2", (which many of us are campaigning for) my guys will always connect up to a different outlet if we are the 3rd due Engine, which has backup responsibilities. I just wanted to post this out to the other members to be carefull of the wye thing. I believe that in a department just west of you, they had a situation where the wye was kicked shut by members exiting the fire floor, resulting in injured members. This gated wye thing should be dropped all together, and I urge the members of this blog to do so before people get hurt. Happy New Year.

Hey Ray, please include myself in the distribution of the video, THANKS.

Ray, I'm interested in what you have. We're trying to get the chief to let us put hose packs on our engines and it's been a s-l-o-w process. We don't have high-rises persay, but we have senior citizen complexes that are pretty well compartmentalized and have standpipes. Our current method to get water to the 2nd or 3rd floor has been proven to be quite time consuming. Bringing hose with us saves alot of time but we're still waiting. We were able to get the smoothbore's and 2 1/2" to 1 3/4" wye for our suggested 1 3/4 hose packs

I'll leave my address,, and look forward to the will be a great topic for company drill!
