I have been reading a UL study on ventilation. It is over 400 pages and is extremely scientific so I have to read some parts several times to fully grasp it. One of the tactics recommended by the study is VES. They say it is safer than a coordinated search from the main entry since you are making entry at your emergency egress point and can isolate yourself simply by closing doors. You are also searching areas that are most tenable and survivable. They make a strong argument but my department has never taken an official position on this type of search.
For those who employ this tactic, how many personnel are typically assigned; what is the search priority (fire floor, above, etc). Are handlines deployed in support of VES?
