Retired Chicago FD District Chief Bennie Crane relates that experience as a firefighter on a truck company. Situations have occurred were concealed space backdrafts have resulted when the 'interior truck' has opened up ceiling and wall spaces.Should the firefighter need to be protected from falling ceiling and concealed space fire that is released that starts to rapidly spread, the stream can be operated overhead once the firefighter with the pole quickly turns and moves back several feet out of harms way. The nozzle positioned slightly behind the firefighter pulling ceiling, allows for water protection.In addition, once water is delivered and worked straight up and overhead of the engine company, whatever water drops back down might be scolding. It is important to position the nozzle BEHIND the firefighter with the pike pole! Allowing a firefighter to pull ceiling from behind the nozzle will allow falling ceiling to drop on head of the nozzle position, and the stream protection is limited as the hole would be made directly over the nozzle position.It is understood that generally it is not safe to operate ahead of the nozzle during a fire attack, but it is necessary in this case.It is important that the officer be positioned near the nozzle behind the firefighter about to pull ceiling: Does fire drop through the ceiling as soon it is pulled?. ![]() Once a hole has been made, can a "new" push of heat be felt indicating approaching fire?.Did the pole virtually bounce back off the ceiling (maybe indicating tongue and groove)?.Did whole sections of ceiling freely drop?.How difficult was it to break into the ceiling?.That first punch into the ceiling will tell much of the story: While positioning just several feet ahead of the nozzle, the firefighter starts to punch through the ceiling. Hose stream + ventilation + building construction + conceal space fire + heat conditions = PULL CEILING (fire may be over head!). The officer had started to do some fast and experienced calculation: Although the heat momentarily lifted, the officer can feel the heat returning to push against them. Now only five feet in the door the engine pauses, and the officer makes a very experienced decision to move up another firefighter just past the nozzle with a pike pole (or plaster hook) to pull ceiling. While slowly advancing low and inward directing the straight stream above and to the rear, the officer can hear the glass breaking and the forcing of the back door. Heat conditions are starting to drop and can be felt pushing from the rear. As FDNY Deputy Chief John Norman has stated time and again, "Vent and ye shall live." It can also be added, "Pull ceiling during the attack, and ye shall live longer & happier."Īs the engine officer finds that the door can be opened easily in this scenario, a heavy push of black smoke about waist level meets the engine. Not to be remiss about roof ventilation, but unfortunately most initial attack staffing levels will not be sufficient for a roof operation, and aggressive horizontal ventilation must take place. A very heavy black push of smoke is pouring from the roof eves indicating some extension into the attic. The size-up has found the fire to be in the rear and it is spreading rapidly. I checked in with Lennard Zinn (a frame builder who literally wrote the book on bike repair), David Kendall at Calfee Design (this shop is the last resort for anyone with a busted-up carbon bike), and Ric Hjertberg at Wheel Fanatyk (where you can find anything you’d need to build wheels, from finely wrought spokes to well-tuned advice) to get their opinions on storage options-and to make sure that it is, in fact, okay to hang a bike by its front wheel, even if the rim is made of expensive and easily damaged carbon.As the first due engine company finishes their hose stretch to the front door of a one-story wood frame constructed house, the hose line is bled of air, and the company officer is preparing for entry. I read Eben Weiss’s The Ultimate Bicycle Owner’s Manual to see what the opinionated Bike Snob NYC (Weiss’s nom de guerre) had to say on the topic. ![]() ![]() I interviewed Chris Hodney, who works with Hacker Architects in Portland, Oregon, another cycling-mad city, and has made a specialty of evaluating bicycle storage for apartments and office buildings. For this review, I polled cyclists on my commute group’s email list (which numbers more than 3,000) in San Francisco-a place where bike infrastructure is expanding but individual living spaces are shrinking-about how they store their bikes.
