Hello everyone,
I wanted everyone to see a new 30 second promo we put together for the Fire Sprinkler Academy. It has been a real blast seeing the students grow and get real serious about a job that saves lives. (I know that Roland, Phil and Tom can relate..) I really do wish I had been able to attend something like this when I got started (cue the "Old Guy" stories about the Automatic and Grinnell days....). I didn't have that privilege. I learned just like everybody else: From somebody that was trying to figure it all out ... and they had learned from someone that was trying to figure it all out. Thank goodness for Cal Morrow dropping off his books when he retired, those books gave me a deep desire to learn more. (If you don't know the name of Cal Morrow, ask someone in the AFSA Carolina's Chapter....) I still look back in those books at the cost of a foot of pipe in 1957 and marvel. And while the labor hours haven't changed too much, the rates sure have! Anyway, we have one semester down and three more to go! Enjoy the video. http://www.youtube.com/user/SprinklerAcademy#p/a/u/0/dboIcTY2zKw Sincerely, Cecil Bilbo Academy of Fire Sprinkler Technology Champaign, IL 217-363-2460 www.sprinkleracademy.com > From: [email protected] > To: [email protected]; [email protected] > Subject: RE: Retro Backflow > Date: Wed, 23 Dec 2009 10:44:21 -0700 > > I have read 11.2.2 and 11.2.2.8.2, and my first comment is that this only > applies to "Pipe Sch."
