The attic and ceiling are very important structural elements for vertical ventilation operations and are often overlooked during training.
The Attic/Ceiling System adjusts with the roof pitch, so that you have a flat ceiling below the roof.
Firefighters can use tools to reach down through the attic space and breach or simulate breaching the ceiling.
You can place sheetrock on the ceiling joists or OSB sheeting. When using OSB, firefighters can simulate breaking sheetrock by striking the OSB sheeting.
The safety chains provide perimeter fall protection. The Attic/Ceiling System offers fall protection if someone accidentally step through a cut vent hole.
You can use OSB to keep debris from falling onto the unit below and make cleanup easier when training is completed.
The ceiling also provides a platform to stand on when stripping and re-sheeting the roof, when using OSB.
The Attic/Ceiling option can be added to a mobile unit at a later date, if desired, and is standard on a stationary unit.
