At a Church fires aiming a Tower Ladder stream into the round or semi-round "Rose Window" is often a great tactic to control fire once it has spread to the "Nave" = the place where most people sit in a church, or fire has extended to the roof above the Nave. Rose windows are often found above the front door of the church entrance. This is an old tactic in advanced church fires. It is unsafe to commit firefighters into the Nave due to the danger of heavy plaster, or heavy chandeliers/light fixtures falling from a greater than normal height on firefighters in the Nave. Also, Heavy Church bells have fallen in church fires and killed firefighters. The only normally valid interior tactic in advanced church fires may be a portable large caliber stream positioned just inside the front door/s. I have written for W.N.Y.F. and other publications about "Church Firefighting" I have operated at 15 major church fires in my career. Captain Bob Rainey FDNY Engine 26 retired.
