Particulates and aerosols are commonly deposited around the wall and ceiling surface area exactly where the upper layer interacted Together with the lining floor (NFPA 2014). Moreover, if these gases have been undergoing flaming combustion as they exited the opening, thermal damage to the wall area is predicted to Keep to the very same concept (DeHaan and Icove 2011).
