Realistic Vent-Enter-Search Training

By CHRISTOPHER S. JOHNSON

Vent-enter-search (VES) is an extremely aggressive and potentially dangerous tactic that only well-trained and experienced outside vent teams should use when the risk vs. reward is deemed appropriate. For example, the most appropriate time to employ this tactic might be a lower-floor fire with a known (or strongly suspected) victim on the floor above. In this situation, it may be faster to access the victim’s anticipated location by ground ladder and window entry than it would be to wait for a line to be placed in service and make the interior stairs.

Recently, members of the Concord (NH) Fire Department’s Battalion 2 conducted realistic VES tactical training as an introduction for newer firefighters and a skills review for more senior members. The goal was to develop a short (45 minutes per company) drill in which all battalion members would participate in a realistic hands-on first-due VES scenario.

TRAINING PROPS CREATED

The department used an acquired two-story, wood-frame, single-family dwelling, but members were limited because they had to secure the building after each training session. Additionally, the building only offered about five second-floor windows; with 24 members to train, this proved insufficient. As with any significant fire service problem, we took the discussion to the kitchen table and developed a successful plan on the back of a napkin.

A battalion member who works for a glass company on the side offered to save and donate used double-hung window sashes from replacement jobs his company completed. Within a week, 60 old sashes (that otherwise would have gone in a dumpster) appeared at the firehouse. The only problem was that the donated sashes were all various sizes and would not fit the existing openings in the acquired structure. To overcome this, members designed and built a training prop that they attached to the structure.

We selected the training window, removed the existing sashes from the window opening, and set those aside in a safe place for later installation to secure the building after training. We built two simple wooden assemblies (designed by Lieutenant Chris Andrews): We laid six-foot-long 2 × 3s on edge and face-screwed 2 × 6s to each of them, forming an “L” shape. We then lag bolted one assembly to each side of a second-floor window opening, forming a set of “tracks” into which we could slide the donated sashes from the top (Figure 1). This arrangement allowed about eight inches of variation in sash width. We also installed a scrap piece of 2 × 3 horizontally below the sill to create a stop so the sashes couldn’t slide or fall out from the bottom of the tracks.

With two sashes stacked in the tracks, we created a double-hung window prop that we could break and quickly clear and replace for the next training scenario (photo 1). We used a tower ladder to install the sashes between scenarios, but we also could have accomplished this with a ground ladder or possibly from the interior. We also laid out a tarp on the ground below the training window to catch the majority of the broken glass for easy disposal.

TRAINING SCENARIO

The training’s intent was to place the members in an urgent situation requiring immediate tactical action. Since we all can become complacent when “it’s only training,” we took steps to make the drill as realistic as possible without the benefit of live fire. Although all members had previously trained in this building and were familiar with its layout, they were not briefed on this particular scenario prior to participation.

Likewise, we did not intend to physically exhaust the members but rather to challenge them and to develop solid skills. Thus, we decided not to use the typical adult victim mannequin. We fashioned a baby’s crib near the bedroom closet on the wall opposite the window from a couple of wooden kitchen chairs and couch cushions. We screwed the chairs together side-by-side and placed them with the seats against the far wall and the chair backs facing the room with the spindles forming the side of the crib. We set the cushions on the seats, and we placed an infant mannequin in the crib. Interestingly, after the training, several members said they didn’t know there was a crib in the building and wanted to know if it had been acquired for this drill.

We covered the interiors of the second-floor windows (including the training window) with black plastic to simulate curtains. We placed two spotlights in the hallway just outside the training room door and then placed orange traffic cones over the lights to create the glow of the fire. (Note: Spotlights get hot. Monitor the traffic cones if you use this technique.) We placed two salamander heaters in the hallway to blow heat through the open door of the training room. Finally, we used a theatrical smoke machine to fully charge the second floor so smoke was pushing from around the window prop (photo 2).

We assigned a safety officer/instructor with a thermal imaging camera (TIC) to the second floor during each evolution to monitor conditions and the crew’s progress. The instructor and another member would then reset the props after each drill, quickly sweeping up broken glass, replacing the infant in the crib, and restapling the plastic curtains over the entry window. Meanwhile, members in the tower ladder bucket would clear the broken sashes and replace them for the next drill. Turnaround time between drills was less than five minutes, with the smoke machine being the limiting factor.

INITIAL BRIEFING

Before members participated in the hands-on drill, an instructor conducted a short (approximately 10-minute) briefing and demonstrated VES tactics. Briefing points included the following:


(3) The control man uses ladder roof hooks to “break and rake” the glass and sashes while a searcher dons his mask.

(4) The searcher clears sashes and curtains prior to entry. Note the markedly increased ventilation after he removes the curtains.

(5) The victim is passed out of the window to the control man for removal. Note the roof hooks over the sill, effectively “footing” the ladder, and a six-foot hook extended into the room from the sill as a landmark of the entry/exit window.

(6) The searcher completes his primary search, reopens the door for interior ventilation (if prudent to do so), and then exits via entry window.

HANDS-ON TRAINING/LESSONS LEARNED

Following the initial briefing, each member participated in two complete VES drills—first as the searcher, then as the control member. Each full-speed and real-time drill was completed in less than approximately three minutes and was followed by a short tactical critique. Several interesting points were brought up in the drill critiques or were obvious when watching the members participate.

Members outwardly enjoyed participating in this somewhat challenging and realistic scenario. Given the drill’s nature (breaking things, heat and smoke condition), even the senior members and less excitable firefighters became interested and trained aggressively, even competitively. This was a change from our normally routine and mundane training and, although creativity and setup were required, the expense was minimal (just a few dollars in hardware), but the benefit was immeasurable.
