No two fires are ever the same. Exposure problems and forcible entry, not to mention ground obstructions make this scenario one worth taking a second look at. There are several tactical considerations that you should think about, that will help you when you roll up on one simular to this one. As the weather cools down and creative heating warms up, expect this to be a busy winter. www.lbfdtraining.com/Pages/simulations/2storyvic2.html

Hello C.F.D. This has been refered to as the Bread and Butter fire of C.F.D.. A 2 1/2 to 3 story wood frame residence with baloon construction. There are so many tactical considerations to be observed with this type of structure, we may have to take a few days in getting most of them out to our readers. Any positive input is welcome. As building construction plays a vital role in our occupation, we will lay out some information about the different types of construction. www.lbfdtraining.com/Pages/simulations/2storyvic.html

Balloon framingBalloon framing is a method of wood construction used primarily in Scandinavia, Canada and the United States (up until the mid-1950s). It utilizes long continuous framing members (studs) that run from sill to eave line with intermediate floor structures nailed to them, with the heights of window sills, headers and next floor height marked out on the studs with a storey pole. Once popular when long lumber was plentiful, balloon framing has been largely replaced by platform framing. While no one is sure who introduced balloon framing in the U.S., the first building using balloon framing was probably a warehouse constructed in 1832 in Chicago by George Washington Snow.[8] The following year, Augustine Taylor (1796-1891) constructed St. Mary's Catholic Church in Chicago using the balloon framing method. The curious name of this framing technique was originally a derisive one. As Taylor was constructing his first such building, St. Mary's Church, in 1833, skilled carpenters looked on at the comparatively thin framing members, all held together with nails, and declared this method of construction to be no more substantial than a balloon. It would surely blow over in the next wind! Though the criticism proved baseless, the name stuck. Although lumber was plentiful in 19th century America, skilled labor was not. The advent of cheap machine-made nails, along with water-powered sawmills in the early 19th century made balloon framing highly attractive, because it did not require highly-skilled carpenters, as did the dovetail joints, mortises and tenons required by post-and-beam construction. For the first time, any farmer could build his own buildings without a time-consuming learning curve. It has been said that balloon framing populated the western United States and the western provinces of Canada. Without it, western boomtowns certainly could not have blossomed overnight. It is also a fair certainty that, by radically reducing construction costs, balloon framing improved the shelter options of poorer North Americans. For example, many 19th century New England working neighborhoods consist of balloon-constructed three-story apartment buildings referred to as triple deckers. The main difference between platform and balloon framing is at the floor lines. The balloon wall studs extend from the sill of the first story all the way to the top plate or end rafter of the second story. The platform-framed wall, on the other hand, is independent for each floor. Balloon framing has several disadvantages as a construction method: www.lbfdtraining.com/Pages/simulations/2storyvic.html

Balloon framing has several disadvantages as a construction method: The creation of a path for fire to readily travel from floor to floor. This is mitigated with the use of firestops at each floor level. The lack of a working platform for work on upper floors. Whereas workers can readily reach the top of the walls being erected with platform framing, balloon construction requires scaffolding to reach the tops of the walls (which are often two or three stories above the working platform). The requirement for long framing members. In certain larger buildings, a noticeable down-slope of floors towards central walls, caused by the differential shrinkage of the wood framing members at the perimeter versus central walls. Larger balloon-framed buildings will have central bearing walls which are actually platform framed and thus will have horizontal sill and top plates at each floor level, plus the intervening floor joists, at these central walls. Wood will shrink much more across its grain than along the grain. Therefore, the cumulative shrinkage in the center of such a building is considerably more than the shrinkage at the perimeter where there are much fewer horizontal members. Of course, this problem, unlike the first three, takes time to develop and become noticeable. Balloon framing has been outlawed by building codes in many areas because of the fire danger that it poses. Balloon framing is growing in popularity again in light gauge steel stud construction. For light gauge steel, long framing members are not as much of an issue. Balloon framing provides a more direct load path down to the foundation. Additionally, balloon framing allows more flexibility for trade workers in that it is significantly easier to pull wire, piping and ducting without having to bore through or work around framing members. www.lbfdtraining.com/Pages/simulations/2storyvic.html
