The tactic of Vent-Enter-Isolate-Search (VEIS) has been around for several decades. Its roots are securely anchored in East Coast firefighting. The original tactic of Vent-Enter-Search (VES) was developed and perfected to allow firefighters alternative means to access and remove victims trapped in burning buildings. Many of the concepts associated with VEIS draw on the original skills and abilities developed with VES. Given the latest scientific research and the significant differences between the modern fireground and the firegrounds of the past, it has become necessary to update this rescue tactic. Four basic factors have contributed to the development of VEIS: modern building construction, occupancy layouts, fire loads, and scientific research.
