Two newly assigned TL members were discussing LCS applications when one member identified an incorrect statement. Which comment is incorrect?
A) Openings made in exterior walls or cornices will often permit stream penetration to the seat of the fire. Power tools should be utilized as necessary; be aware that time lost breaching walls to reach the cockloft may lead to extension in exposures.
B) The application of a LCS downward into roof openings from an elevated position can be counter productive. Operating the TL stream into the roof vent holes is generally ineffective and may result in a prolonged operation.
C) The Turbomaster nozzle is preferable when deep penetration of the stream is necessary to hydraulically overhaul stock. Increasing nozzle pressure within allowable limits will often facilitate access into partitions and sidewalls.
D) When conditions such as heavy clutter or doubtful floor stability exist, the IC may order all personnel removed from the bucket, lock the monitor in place, and extend the bucket into the building via a large window or other opening to achieve extinguishment and hydraulic overhaul.

Breaching exterior walls may be necessary to gain access for life saving or stream penetration. Members of a Queens TL reviewing this procedure would know which choice below to be correct?
A) Exterior walls can be breached with a maul and/or power tool; however this is an arduous operation requiring frequent relief. When using the maul to breach cinder blocks, start at the bottom.
B) When the power saw is being used to cut through brick and concrete, the carbide tipped saw blade shall be used. Electric or pneumatic hammers may also be used for breaching operations from the bucket, when necessary.
C) Cuts in brick should be triangular with the vertex angle upward to prevent further collapse. The 1st and 2nd cuts should be at the mortar joint since the easiest cut is at the brickwork and the blade at this point will be worn.
D) Make the opening large enough so that the saw can be inserted to cut an inner wall, if necessary. Usually, on two-course brick walls, the second course can be removed by hand tools or a heavy stream.
