NOTES

The Ventilation Profile as defined earlier is the appearance of the entire fire building's ventilation openings, showing the flow paths of any air movement into the structure as well as smoke, heat or flame out of the structure.

The Vent Profile: The visual condition presenting at a single ventilation opening relating to a unidirectional, bidirectional, or dynamic flow integrated with the four fire development assessment indicators (Smoke, Air, Heat and Flame). If the vent profile is the only ventilation opening then and only then can the vent profile be used in VP = BE + SAHF.
