    session of training minutes will be the third section we run on truss roofs. We look at a building that had a heavy timber wood truss roof system. It was a large manufacturing facility. And the ceiling on the first floor concealed the wood trusses above. In the second video, we looked at a mercantile occupancy. And occupancy where we might not suspect a truss roof. The truss roof was a steel-framed parallel cord truss system. The appearance on top of the roof. Provided a flat roof surface, which may confuse firefighters, or lead firefighters to believe that the building was not constructed with a truss . In our third building, we're again looking at a smaller mercantile occupancy. From the exterior of the structure, from the A side, looking from the street. We missed some size-up cues. Our size-up cues are actually misleading. We look at the building and do not see any form of a wood truss . If we move around to the B side of the building, again, we see a parapet wall, but what we see appears to be a flat roof. We don't see the large rounded over roof surfaces that you would expect to find with a bow string truss . Yet, this building is constructed with a heavy timber bow string truss . We're going to walk inside and take a look at that roof system. As we enter the front door of the occupancy, we notice a suspended ceiling, an aluminum grid ceiling with tiles are in place. At this point, we still have no idea that this building has a heavy timber wood truss roof. We need to look further into the building to identify the truss roof on this building. As we walk through this occupancy, the heavy timber truss roof's system is clearly obvious. The lack of a ceiling will allow firefighters to readily identify the fires location, and to be
    defensive posture because the fire has involved and taken hold in the truss base. As we walk through the occupancy, we discover skylights. The skylights provide an opportunity. For quick ventilation, as they are natural
    joisted roof. A flat roof, independent of the heavy timber of bowstring truss . Therefore, a fire in this room or space can be fought just like any other structure fire that does not involve a truss roof system. As we enter the structure through the front door, we encounter a ceiling. Here is another door that leads directly
