Ventilation is a cornerstone tactic for firefighters – the first letter in the essential acronym VEIS (vent, enter, isolate, search). Whether horizontal or vertical, ventilation tactics are essential to the overall fireground operation. In recent years, more research has identified the importance of coordinating ventilation and fire attack operations to preserve firefighter safety. The FireRescue1 Ventilation resource page details such research, and provides additional expert analysis about ventilation tactics. There’s also news related to ventilation operations, including several Los Angeles Fire Department firefighters who sustained burns in an explosion.
