[00:00:03]
ALRIGHT, THANKS FOR COMING OUT TONIGHT.
[Training Event on January 24, 2022.]
FOR THOSE OF YOU WHO DON'T KNOW ME, I'M TOM DEMMER LING ONE OF THE ASSISTANT CHIEFS, RUBBER PROVIDENCE.THIS IS MIKE RUSSELL, THE OTHER ASSISTANT CHIEF.
SO MIKE HANDLES OPERATIONS AND TRAINING.
I HANDLE THE FIRE MARSHAL AND THE THINGS.
ONE OF THE BIG RESPONSIBILITIES OF MY JOB IS FIRE PROTECTION SYSTEMS. WHETHER IT'S ACCEPTANCE, TESTING, UM, INSPECTION PLAN, REVIEW, ALL KINDS OF FUN STUFF.
WE'RE GONNA TRY TO HANDLE ANY QUESTIONS WE CAN FROM ANYONE WHO'S HERE IN PERSON AS WE GO.
IF ANYONE WHO'S NOT HERE IN PERSON HAS ANY QUESTIONS, JUST EMAIL MIKE AND HE'LL RELAY THEM TO ME.
WE'LL DO OUR BEST TO ANSWER THEM.
UH, THE MEETING IS BEING RECORDED AND BROADCAST PUBLICLY.
SO JUST BEAR THAT IN MIND, WHEN QUESTIONS ARE BEING ASKED, SOME OF THE THINGS THAT WE USED TO HAVE IN HERE AS A MORE SPECIFIC, UH, SPECIFICALLY TO PROPERTIES AND THINGS LIKE THAT, THAT'S BEEN TAKEN OUT.
WE REALLY DON'T REALLY WANT REFERENCES TO FACILITIES IN HERE.
SO I DON'T WANT TO GET INTO TOO MUCH DETAIL ON THAT TONIGHT, BUT WE'LL ANSWER ANY OTHER QUESTIONS THAT WE HAVE.
SO THE FIRE PROTECTION SYSTEMS THAT WE'RE MOST FAMILIAR WITH, OR THE ACTIVE FIRE PROTECTION SYSTEMS, FIRE ALARM SPRINKLERS, THE KINDS OF STUFF THAT GETS YOU UP IN THE MIDDLE OF THE NIGHT, CAUSE OF AN ALARM.
THE OTHER FIRE PROTECTION SYSTEM IS A PASSIVE TYPE.
SO WE SEE THAT IN RESIDENTIAL CONSTRUCTION, THAT'S IN COMMERCIAL AS WELL, BUT WHEN YOU'RE IN A TOWNHOUSE, IT'S FIRE SEPARATED, OR A GARAGE IS SEPARATED FROM THE HOUSE.
THAT'S ALL PASSIVE FIRE PROTECTION ACTIVE AS AGAIN, THE SPRINKLER AND ALARM END OF THINGS.
SO PASSIVE, WE HAVE FIREWALLS, FIRE BARRIERS, FIRE PARTITIONS, COMMERCIAL PROPERTIES, WE'LL SEE THEM MARKED.
UM, SO IF ANYONE PENETRATES THAT WITH A PIPE OR ELECTRICAL CONNECTION, THEY HAVE TO REPAIR THAT PENETRATION TO KEEP THAT TWO HOUR RATING INTACT OR WHATEVER THE RATING MAY BE.
DIFFERENT TYPES OF MASONRY THAT CAN ADD UP TO DIFFERENT RATINGS.
THIS IS A RESIDENTIAL TOWNHOUSE BEING CONSTRUCTED AND YOU SEE THAT PURPLE BOARD IN BETWEEN THE TWO DWELLINGS THAT'S SHAFT LINER OR SPECIFIC TYPE OF GYPSUM BOARD THAT KEEPS THAT PARTITIONED IN PLACE.
IT'S SUPPOSED TO BE SUPPORTED INDEPENDENTLY FROM EITHER SIDE, UNLESS THEY MEET CERTAIN EXCEPTIONS.
SO WE HAVE A FIRE IN ONE TOWNHOUSE AND THE WALL COLLAPSES.
THE ADJOINING TOWNHOUSE SHOULD KEEP ITS FIREWALL INTACT.
SO THE CODE SAYS THAT EACH TOWNHOUSE TOWNHOUSE HAS TO BE SEPARATED BY TWO TO ONE HOUR FIRE RESISTANCE RATED WALL ASSEMBLIES, OR A COMMON TWO HOUR WALL THERE'S IN THE CODE.
SO THIS IS JUST VERY GENERALLY SPEAKING.
IF IT'S SPRINKLERED, YOU CAN USE A COMMON WALL WITH A ONE HOUR RATING.
SO IN PENNSYLVANIA, TOWNHOUSES GENERALLY ARE REQUIRED TO BE SPRINKLERED.
UM, ONE AND TWO FAMILY DWELLINGS ARE NOT.
SO WE'RE GENERALLY SEEING SPRINKLER SYSTEMS IN THESE AND GETTING OVER THE ONE HOUR AND SEE THE BOATS UP BETWEEN THE TWO UNITS.
SO WHEN YOU GO BACK TO THE, SO ON THIS, WE'RE LOOKING FROM ONE UNIT AT THE WALL AND YOU SEE THE BRACKETS ATTACHING IT A LITTLE.
UH, SO THEY'RE GOING TO BE THE SAME ON THE OTHER SIDE.
AND THEN IN THIS CASE, IT IS TWO SEPARATE WALLS.
SO YOU HAVE BRACKETS ON EITHER SIDE THAT WAY, IF ONE UNIT FALLS OR COLLAPSES THE UNIT, THAT'S STILL STANDING, THAT PARTITION IS STILL GOING TO BE INTACT, RIGHT? YEAH.
SO FOR THE PEOPLE THAT ARE LISTENING ONLINE, THE QUESTION WAS THAT IS THAT TWO SEPARATE WALLS OR ONE WALL.
SO IT'S IN THIS CASE, IT'S TWO SEPARATE WALLS.
UM, IT WAS THEN ASKED IF THEY'RE ATTACHED AT ALL.
SO EACH SECTION OF THAT PURPLE SHAFT WALL IS ONLY ATTACHED TO THE WOOD FRAMING ON ITS SIDE OF THE SEPARATION.
THERE, THE TWO PURPLE BOARDS ARE NOT ATTACHED TO ONE ANOTHER.
SO THAT FALLS HALF OF THAT'S GOING TO STAY UP.
SO BECAUSE THAT FIRE SEPARATION DOESN'T PENETRATE THE ROOF LINE AND CREATE ANY KIND OF A PARAPET, UM, IT'S REQUIRED THAT THE ROOF HAS FIRE RATED SHEATHING EXTENDING FOUR FEET ALONG THE ROOF LINE IN EITHER DIRECTION.
SO THAT'S WHY YOU SEE THAT DIFFERENT COLORED SHEATHING THERE THAT
[00:05:01]
ANYTIME DID YOUR ROOF SHEETING, THEY'RE INTERLOCKING IT.THAT'S WHY YOU HAVE A FOUR FOOT THAN AN EIGHT FOOT STICKING OUT, BUT THE MINIMUM IS A FOREFOOT.
SO WHEN THE FIRE GOES UP AND IT REACHES THAT HORIZONTAL SURFACE AND STARTS RUNNING ACROSS THE ATTIC, IT'S NOT GOING TO BLOW RIGHT THROUGH.
IT'S GOING TO BE SLOWED DOWN A LITTLE BIT BY THE FIRE RATED SHEATHING.
SO IT'S ALL IMPORTANT TO US BECAUSE WHEN WE GO TO ONE OF THESE FIRES, GENERALLY, THERE'S NO ACTIVE FIRE SUPPRESSION IN THERE.
NOW WE'RE GETTING INTO SPRINKLER SYSTEMS THERE.
UM, BUT THEY HAVE LIMITATIONS.
THEY'RE NOT GOING TO BE SPRINKLERED IN THE ATTIC.
SO HOW CAN WE BEST ATTACK THE FIRE USING THE BUILDING CONSTRUCTION TO OUR ADVANTAGE.
THIS IS NOT A TOWNHOUSE, BUT, UM, THERE'S A DECENT PICTURE THAT SHOWS HOW WELL THAT SHAFT WALL HOLDS UP.
SO THERE WAS A LOT OF FIRE THERE LOOKING UP THERE.
YOU CAN SEE THAT PURPLE SHAFT LINER, AND THEN YOU CAN ACTUALLY SEE UNCHARTERED WOOD FRAMING IT, WHERE THE FIRE WAS JUST BREAKING THROUGH WHEN THE FIRE DEPARTMENT GOT IT EXTINGUISHED.
SO RESIDENTIAL GARAGES, UM, THEY'RE REQUIRED TO BE SEPARATED FROM THE LIVING SPACE OF THE HOME.
AGAIN, WE'RE SPEAKING KIND OF IN GENERALITIES BECAUSE THERE'S ALWAYS SOME KIND OF AN EXCEPTION IN THERE, BUT FROM THE RESIDENTS AND THE ADDICTS, YOU'RE GENERALLY GOING TO HAVE HALF INCH DRYWALL APPLIED ON THE GARAGE SIDE.
THAT'S PROTECTING THE WOOD FRAMING AND KEEPING THE FIRE CONTAINED TO THE GARAGE.
UM, IF THERE'S ANY HABITABLE ROOMS LIKE A BEDROOM OR ANYTHING ABOVE THE GARAGE, IT'S REQUIRED TO HAVE FIVE, EIGHT SINCH TYPE X.
IT SHOULD SAY I MISSED A LETTER THERE NO FIVE EIGHTS TYPE X GYPSUM ON THE CEILING OF THE GARAGE TO KEEP THE FIRE OUT OF THERE.
IT'S A GARAGE, THE DOOR BETWEEN THE LIVING SPACE AND THE GARAGE IS REQUIRED TO HAVE A MINIMUM 20 MINUTE FIRE RATING AND BE EQUIPPED WITH SOME KIND OF SELF-CLOSING DEVICE.
SO AGAIN, THAT'S GOING TO HELP US OUT BY KEEPING THE FIRE TO THE GARAGE, ANOTHER LOCAL FIRE.
SO THERE'S TWO CARS IN THIS GARAGE.
UM, FIRE OCCURRED WITHIN THE GARAGE AND WE'LL SEE A LITTLE LATER ON HOW THE DRYWALL AND STUFF HELD UP, BUT YOU CAN SEE THE FIRE STILL DID EXTEND OUTSIDE.
CAUSE VINYL SIDING DOES A REALLY NICE JOB OF HELPING THE FIRE SPREAD.
AND WE STILL, EVEN IF THERE'S PASSIVE FIRE PROTECTION IN PLACE, IT'S NOT GOING TO BE FOOLPROOF.
WE STILL HAVE TO CONSIDER WHERE ELSE THE FIRE IS GOING TO GO.
SO TOP, RIGHT, YOU'LL SEE THE WOOD FRAMING THAT WAS BEHIND THE DRYWALL IN THE GARAGE, BUT TOTALLY CLEAN, NOT BURN.
THIS IS AFTER IT WAS REMOVED DURING OVERHAUL.
AND THEN THE PICTURE ON THE LEFT IS SHOWING THE DOOR BETWEEN THE GARAGE AND THE LIVING SPACE.
YOU CAN SEE THAT HELD UP PRETTY WELL.
I MEAN, THERE'S NOT A WHOLE LOT OF DAMAGE IN THERE SIDE OR SO PASSIVE FIRE PROTECTION BUYS US TIME.
IT'LL SLOW THE SPREAD OF THE FIRE.
WE CAN TAKE ADVANTAGE OF IT TO MAKE SURE THAT WE'RE KEEPING THE FIRE IN CHECK, LETTING IT, LETTING IT HELP US, LETTING IT SLOW IT DOWN FOR US.
EVERY BUILDING ISN'T BUILT TO THE SAME CODE THEY'RE BUILT OVER TIME.
EVERYTHING IN THIS PRESENTATION IS BASED ON MODERN CODES, BUT WE KNOW THERE'S PLENTY OF OLDER BUILDINGS AROUND HERE.
PEOPLE SURPRISINGLY PERFORM ALTERATIONS WITHOUT GETTING PERMITS.
SO SOMETIMES, UM, SOMETHING WILL BE DONE THAT WE'RE, WE MIGHT EXPECT TO BE CODE COMPLIANT.
IT'S NOT, AND IT CAN STILL TAKE OTHER PATHS.
LIKE WE SAW LIKE A RAJ FIRE THAT IT CAN GET OUTSIDE OF THAT COMPARTMENT AND TRAVEL UP PRETTY QUICKLY.
SOMETIMES THE OUTSIDE IN FIRES ARE A LOT WORSE THAN THE INSIDE FIRES, MORE PASSIVE FIRE PROTECTION, SMOKE AND FIRE DAMPERS.
WE'RE GETTING MORE INTO COMMERCIAL HERE, BUT THIS PICTURE IS A FIRE DAMPER AND A HOTEL ROOMS. THIS IS BETWEEN THE GUEST ROOM AND THE HALLWAY.
IT'S GOING TO KEEP THE FIRE FROM GETTING THROUGH GOLDEN OPENING PROTECTIVE.
SO BECAUSE THIS IS GOING THROUGH A RATED WALL, THERE NEEDS TO BE SOME KIND OF DAMPER IN PLACE TO PROTECT THAT OPENING FIRE WERE TO OCCUR.
THIS IS ACTUALLY A HOTEL THAT WE WERE DOING, THE FINAL ACCEPTANCE ON IT.
AND WE FOUND THAT THERE WERE A COUPLE OF HUNDRED OF THESE FIRE DAMPERS THAT HAD THE FUSIBLE LINKS PAINTED ON THEM.
SO THEY WOULDN'T NECESSARILY OPERATE IN THE TIME THAT THEY EXPECTED TO.
SO ANOTHER LIMITATION OF PASSIVE FIRE PROTECTION TOP RIGHT, IS A SMOKE DAMPER.
SO YOU CAN KIND OF SEE A SMOKE DETECTOR
[00:10:01]
ON THE OUTSIDE OF THAT HOUSING THAT DETECTS SMOKE WITHIN DUCT WORK, IT'LL CLOSE THE DAMPERS AND THAT PREVENTS SMOKE FROM TRAVELING THROUGHOUT A BUILDING FROM ONE COMPARTMENT TO ANOTHER.MORE PASSIVE FEATURES, FIRE PROTECTION AS STRUCTURAL MEMBERS.
YOU'RE ONLY GOING TO REALLY SEE THIS IN TYPE ONE CONSTRUCTION, WHICH IS PRETTY RARE.
UM, BUT YOU CAN SEE SPRAY FIREPROOFING APPLIED TO THE BEAMS IN THIS KIND OF BLENDS IN WITH THE CEILING, BUT DEPENDING ON THE TYPE OF BUILDING AND HOW IT'S BUILT, UM, IT CAN BE A ONE, TWO OR EVEN A THREE-HOUR RATING TO THOSE STRUCTURAL MEMBERS HELPS US IN A FIRE THAT IS NOT GOING TO FAIL VERY QUICKLY, BUT THIS IS PROBABLY LESS THAN LESS THAN 3% OF THE COMMERCIAL BUILDINGS IN THE TOWNSHIP.
MOST OF THE COMMERCIAL CONSTRUCTION THAT WE SEE AS TYPE TWO.
SO IT'S NON-COMBUSTIBLE, BUT IT'S NOT PROTECTED.
WE'LL START FALLING APART RATHER QUICKLY.
SO WE KIND OF BLEW THROUGH THAT CAUSE I DON'T THINK FIRE, OR I DON'T THINK PASSIVE FIRE PROTECTION IS WILDLY INTERESTING.
IT'S STILL IMPORTANT, BUT ANYBODY HAVE ANY QUESTIONS ABOUT ASSET FIRE PROTECTION, RIGHT? SO ACTIVE FIRE PROTECTION SYSTEMS. WE'RE GOING TO GO THROUGH A WHOLE LIST OF THEM.
WE'RE NOT GOING TO TALK ABOUT ALL OF THEM, BUT JUST TO GIVE YOU AN IDEA OF WHAT'S OUT THERE, SPRINKLER STANDPIPE, FIRE PUMPS, KITCHEN SUPPRESSION, FIRE ALARM, DRY CHEMICAL, CLEAN AGENT, EXPLOSION, SUPPRESSION, AND EVEN FIRE EXTINGUISHERS AND FIRE HYDRANTS.
IT'S FOUR DIFFERENT TYPES OF SPRINKLER SYSTEMS. UH, MOST COMMON IS A WET PIPE.
SO THERE'S WATER THROUGHOUT THE WHOLE SYSTEM THAT HAS TO BE IN AN AREA THAT ISN'T SUBJECT TO FREEZING A DRY PIPE SYSTEM WOULD BE INSTALLED ANYWHERE THAT TEMPERATURE COULD FALL BELOW 40 DEGREES.
SO ANYTHING ON THE FREEZING PART OF THAT OR THAT COULD FREEZE IS GOING TO BE FILLED WITH JUST AIR REACTION SYSTEM IS INSTALLED IN USUALLY KIND OF HIGH VALUE AREAS COULD BE A SERVER ROOM, UH, ART MUSEUM, WHATEVER, BUT IT, IT REQUIRES THE ACTIVATION OF ALARM DEVICES OR A SENSING LINE.
IN ADDITION TO JUST THE SPRINKLER ACTIVATION AND THEN A DELUGE SYSTEM IS FOR SPECIFIC HIGH HAZARDS.
YOU MIGHT SEE IT WHERE A TRACTOR TRAILER UNLOADS, FLAMMABLE LIQUIDS OR SOMETHING LIKE THAT.
BUT IT'S GOING TO JUST DUMP A TON OF WATER VERY QUICKLY.
WET PIPE IS THE MOST BASIC DESIGN THERE'S WATER THROUGHOUT ALL THE PIPING, EXCEPT FOR THE FIRE DEPARTMENT CONNECTION.
SO ON THIS, I THINK IT'LL HIGHLIGHT IT LATER, BUT THE CHECK VALVE IS GOING TO HOLD THE WATER PRESSURE IN THE SYSTEM PIPING ON THE SYSTEM SIDE, WHICH IS ABOVE THE CHECK VALVE.
SO THE CHECK VALVE IS RIGHT THERE FOR EVERYONE IN PERSON OR ANYONE.
THAT'S NOT IT'S THE DEVICE BETWEEN THE TWO GAUGES.
SO ANYTHING FROM HERE UP TO THIS CHECK VALVE IS GOING TO BE DRY.
AND THEN ANYTHING AFTER THAT IS GOING TO BE FILLED WITH WATER DRY PART.
SO WE'LL TALK PART OF OUR JOB IS OBVIOUSLY PROPERTY PRESERVATION.
SOMETIMES EITHER A SPRINKLER BREAK OCCURS AND WE NEED TO SHUT THE SYSTEM DOWN OR THE FIRES OUT.
WE NEED TO SHUT THE SYSTEM DOWN.
NONE OF THIS HAS MEANT TO GO ABOVE AND BEYOND ANY POLICIES THAT YOU GUYS HAVE AT YOUR RESPECTIVE COMPANIES.
UM, AND IT SHOULD ALL ALSO BE DONE IN ACCORDANCE WITH THE INCIDENT COMMANDERS PERMISSION, BUT TO SHUT DOWN ONE OF THESE SYSTEMS FOR A WET PIPE, ONCE WE VERIFY THERE'S NO FIRE OR THAT IT'S EXTINGUISHED AND THE INCIDENT COMMANDER TELLS US TO SHUT IT DOWN, THERE'S GOING TO BE A CONTROL VALVE UNDERNEATH THE CHECK VALVE FOR THE RISER.
THAT'S HIGHLIGHTED IN BLUE THERE.
AND I CLOSE THAT AND THEN YOU'RE GOING TO OPEN THE MAIN DRAIN TO THE SYSTEM.
THAT'S GOING TO RELEASE ALL THE WATER FROM THE SYSTEM PIPING REALLY EASY ON WET PIPE SYSTEMS, BUT WE SHOULD ONLY BE DOING THAT WHEN WE KNOW THE FIRE'S EXTINGUISHED OR IT'S A BREAK AND THERE IS NO FIRE.
AND THE INCIDENT COMMANDER IS TELLING US TO DO SO.
DRY PIPE SYSTEMS ARE A LITTLE BIT MORE COMPLICATED THAN WHAT PIPE.
UM, SO ANYTHING ON THE SUPPLY SIDE UP TO THE CHECK VALVE IS GOING TO BE FILLED WITH WATER.
AND THEN ON THE SYSTEM SIDE IS GOING TO BE FILLED WITH AIR.
IT'S A DIFFERENTIAL STYLE VALVE.
SO IF YOU SEE ON THERE, THERE'S
[00:15:01]
A LOT MORE SURFACE AREA ON TOP OF THE WATER THAN THERE IS WHERE THE WATER COMES THROUGH THE VALVE ITSELF.SO YOU'LL USUALLY SEE ON THE TOP, YOU'LL ALWAYS SEE ON THE TOP GAUGE OF THE DRY PIPE SYSTEM, THAT THERE'S LESS PRESSURE THAN ON THE BOTTOM GAUGE WHERE THE WATER IS, THE REASON LESS AIR CAN HOLD BACK.
MORE WATER IS BECAUSE OF THAT DIFFERENTIAL STYLE, VAL FOR DRY PIPE SYSTEMS, THE FIRE DEPARTMENT CONNECTION CAN'T CONNECT AFTER THE CHECK VALVE.
SO IT'S GOING TO COME IN BEFORE IT, THE CHALLENGE THAT GIVES US IS IF SOMEONE CLOSES A CONTROL VALVE TO THE DRY PIPE SYSTEM, AND WE SHOW UP WITH A PUMPER AND HOOK UP TO THE FIRE DEPARTMENT CONNECTION, WE MAY NOT ACTUALLY BE PUTTING WATER INTO THE SYSTEM.
IF THAT CONTROL VALVE IS CLOSED, IT SHOULD BE OPEN.
IF IT'S NOT THOUGH, WE HAVE NO WAY TO BYPASS IT.
THAT'S SOMETHING TO KEEP IN MIND, VERY SIMILAR PROCESS TO SHUTTING DOWN A DRY PIPE, SPRINKLER, THOSE, THE CONTROL VALVE OPENED THE MAIN DRAIN.
SEE OF THIS PLATE, JUST A QUICK ANIMATION SHOWING HOW A DRY PIPE SYSTEM OPERATES.
IT WAS SHOWING A LOT OF THE TRIM AND EVERYTHING.
BUT THE IDEA IS THAT ONCE THAT AIR IS DEPLETED, AFTER THE SPRINKLER ACTIVATES WATER IS GOING TO FOLLOW IT, THAT VALVE THAT YOU JUST SAW RELEASE IS GOING TO LATCH OPEN WATER.
SO THE QUESTION IS, HOW LONG DOES IT TAKE FROM THE AIR COMING OUT TO THE WATER TO FOLLOW THE, THAT DEPENDS ON THE SIZE OF THE SYSTEM AND THE HAZARD IS PROTECTING.
SO THE CODE GIVES YOU A FEW DIFFERENT THRESHOLDS.
GENERALLY, IT'S GOING TO BE UNDER A MINUTE, BUT THERE'S A FEW INSTANCES WHERE IT CAN BE OVER A MINUTE AFTER CERTAIN DEVICES TO HELP IT ALONG.
ANY OTHER QUESTIONS ABOUT WET PIPER, DRY PIPE SYSTEMS. IT'S A SPRINKLER SYSTEMS ARE DESIGNED USUALLY AS CONTROL MOTOR SUPPRESSION MODE.
THEY'RE USUALLY DESIGNED AS CONTROL MODE.
SO IT MEANS IT'S GOING TO CONTROL THE FIRE FROM SPREADING, BUT IT'S NOT GOING TO EXTINGUISH IT.
THERE'S A CHANCE THAT THE SPRINKLERS GOING TO PUT THE FIRE OUT, BUT IT DOESN'T MEAN IT'S NOT DESIGNED TO DO THAT.
THIS IS A FIRE TO WAREHOUSE, HOW TO CONTROL MODE SPRINKLER SYSTEM IN IT.
SO AGAIN, MEANT TO CONTAIN THE FIRE.
AND THEN THE FIRE DEPARTMENT BRINGS A HOSE LINE INTO FINISH EXTINGUISHING IT.
AND THE TWO SPRINKLERS ACTUALLY PUT THE FIRE OUT.
SO IT WAS THREE PALLETS WORTH OF GOODS THAT WERE ON FIRE.
AND WHEN THESE SYSTEMS ARE DESIGNED, THEY'RE USUALLY DESIGNING FOR A 1500 TO 3000 SQUARE FOOT FLOOR AREA.
THEY DO ALL THEIR PRESSURE CALCULATIONS.
TWO SPRINKLERS MIGHT BE COVERING 70 OR 80 SQUARE FEET.
SO YOU'RE GOING TO GET A LOT MORE PRESSURE THROUGH THOSE TWO SPRINKLERS THAN IF IT WERE THE WHOLE DESIGN AREA THAT'S FLOWING WATER.
AND THAT'S HOW WE CAN SOMETIMES GET AWAY WITH THE FIRE BEING EXTINGUISHED BY JUST A COUPLE OF SPRINKLERS.
THIS IS ANOTHER INSTANCE OF A SPRINKLER SAVE IN THE TOWNSHIP.
IT WAS A DEHUMIDIFIER ON FIRE IN A RELATIVELY SMALL
[00:20:01]
ROOM, BUT THE SYSTEM PUT IT OUT.THIS HAD A FIRE PUMP BEHIND IT.
AND THEN THIS TINY LITTLE BASKET AND ANIMATRONIC DEVICE CAUGHT FIRE AND A SPRINKLER PUT IT OUT.
IT WAS A SINGLE SPRINKLER, BUT WHEN THE FIRE DEPARTMENT GOT THERE, WE ACTUALLY HAD TROUBLE FINDING THE SOURCE OF THE FIRE.
WE SAW THE SPRINKLER WAS ACTIVATED, BUT THERE WAS NO HEAT.
UM, EVENTUALLY WE TRACKED IT DOWN TO THIS, BUT ESPECIALLY WE GET INTO WAREHOUSES AND LARGER PLACES LIKE THAT.
WHEN THERE'S A FIRE AND THE SPRINKLERS ACTIVATE, IT'S GOING TO DISTURB THAT SMOKE LAYER AND BRING IT DOWN CLOSER TO THE FLOOR.
SO IT'S SOMETHING TO KEEP IN MIND WHEN YOU'RE GOING IN THERE.
THE SMOKE THAT YOU'RE EXPECTING TO BE CLOSER TO THE CEILING MAY NOT BE, AND IT'S GOING TO CAUSE SOME ISSUES WITH VISIBILITY AND THINGS AS THE WATER COOLS THE SMOKE.
ANY QUESTIONS ABOUT SPRINKLERS AT ALL? YEAH.
THE QUESTION IS, ARE THERE ANY ANTIFREEZE SYSTEMS AROUND STILL? THERE ARE, UM, THERE WAS A MORATORIUM ON ANTIFREEZE AND SPRINKLER SYSTEMS. AND LAST I KNEW THERE WAS NO APPROVED ANY FREEZE OR ALL SYSTEMS. THERE ARE CERTAIN SYSTEMS YOU CAN GET AWAY WITH, BUT, UM, WE STILL HAVE THEM OUT THERE.
CAUSE IF YOU HAD ONE, YOU'RE STILL ALLOWED TO KEEP IT.
BUT THE CHALLENGE WITH ANY FREE SYSTEMS IS THAT ANY FREEZES COMBUSTIBLE.
SO THEY FOUND PARTICULARLY IN RESIDENTIAL FIRES, IF THERE WAS TOO MUCH ANTIFREEZE COMING OUT BEFORE THE WATER FOLLOWED IT, IT WAS ACTUALLY SUPPORTING THE FIRE RATHER THAN EXTINGUISHING IT.
SO NFTA CAME OUT AND SAID, THE ONLY TIME YOU CAN USE ANTIFREEZE IS WHEN IT COMES PREMIXED FROM THE FACTORY.
CAUSE THAT KEEPS SOMEBODY FROM MESSING UP, PUTTING TOO MUCH, ANY FREEZE IN IT THAT GAVE US A FEW YEARS ON THAT.
AND THEN THEY SAID, NO ONE CAN USE ANTIFREEZE UNTIL IT'S, THERE'S A LISTED ANY FREE SOLUTION.
AND ANY FACTORIES ARE STILL WORKING ON THAT.
AS FAR AS I KNOW, TIM, DO YOU KNOW IF THEY CAME OUT WITH LISTED ONE? OKAY.
SO YEAH, IT SOUNDS LIKE IT'S NOT OUT YET, BUT GOOD QUESTION.
SO STANDPIPES, UM, THREE DIFFERENT CLASSES OF STANDPIPES CLASS ONE IS A TWO AND A HALF INCH OUTLET FOR FIRE DEPARTMENT OPERATIONS.
LAST TWO AS AN INCH AND A HALF OUTLET WITH HOSE FOR OCCUPANT USE.
AND THEN A CLASS THREE HAS BOTH.
SO IT'S GOING TO HAVE TWO DIFFERENT OUTLETS ON IT.
SO WITHIN JUST THE CLASSES OF STANDPIPE SYSTEMS, THERE'S ALSO TYPES, AUTOMATIC DRY SYSTEMS WORK, KIND OF LIKE A DRY PIPE SPRINKLER.
WE DON'T HAVE ANY AROUND HERE.
I'VE NEVER SEEN ONE, BUT THEY'RE THERE SOMEWHERE AUTOMATIC WET.
THERE'S SOME OF THE TOWNSHIP AND THEY USUALLY NEED TO BE SUPPORTED BY A FIRE PUMP TO GET THAT, UH, DEMAND OUT OF THEM.
SO WHEN WE'RE DOING STAMP OPERATIONS, FIGURE BETWEEN THE ELEVATION LOSS, THE FRICTION LOSS OF THE HOSE AND THE NOZZLE PRESSURE YOU NEED, THERE'S USUALLY A FAIR BIT OF PRESSURE INVOLVED IN GETTING WATER OUT OF THAT STAND PIPE SYSTEM.
AUTOMATIC MEANS THAT THE SYSTEM IS CAPABLE OF PROVIDING WHAT WE NEED OUT OF IT WITHOUT OUR INTERVENTION WITH A FIRE DEPARTMENT PUMPER.
SO WE HAVE PLENTY OF WE'RE GET INTO NEXT MANUAL WET SYSTEMS. SO WHEN YOU GET INTO HOTEL, THERE'S USUALLY STANDPIPES IN THE HALLWAY.
THEY MAY HAVE A FIRE PUMP, BUT THAT FIRE PUMP IS THERE TO SUPPORT THE SPRINKLER DEMAND, NOT THE STANDPIPE DEMAND.
SO WHEN WE GET THERE, IF WE'RE GOING INTO OPERATIONS, USING THE STANDPIPES, WE SHOULD HAVE A FIRE DEPARTMENT, PUMPER HOOKED UP TO THAT FIRE DEPARTMENT, CONNECTION, SUPPORT THE PRESSURE AND VOLUME THAT WE NEED AND THEN MANUAL DRY.
YOU'LL FIND THOSE PLACES IT'S GOING TO FREEZE.
THERE'S A FEW IN THE TOWNSHIP, USUALLY PARKING GARAGES.
THIS SLIDE USED TO GET INTO MORE DETAIL OF WHICH OCCUPANCIES HAD WHICH SYSTEMS, BUT AGAIN, BECAUSE IT'S BEING BROADCAST PUBLICLY, WE'RE NOT GOING TO GET INTO THAT ON HERE AND THEN SEMIAUTOMATIC DRY.
UM, THAT IS WHERE AT THE STANDPIPE HOSE VALVE YOU'D HAVE A, ALMOST LIKE A REMOTE POLL STATION.
SO THE FIREFIGHTER COULD OPERATE THAT POLL STATION.
IT WOULD TRIP A VALVE AND SEND WATER INTO THE PIPE.
SO SEMI-AUTOMATIC, IT'S NOT JUST GOING TO OPERATE LIKE A DRY PIPE.
SPRINKLER, LAST ONE, YOU HAVE YOUR TWO AND A HALF INCH HOSE VALVE
[00:25:01]
COMING OFF OF A RISER.EVERYTHING IN THE TOWNSHIP IS NATIONAL STANDARD THREAD.
WE DON'T HAVE ANY CLASS, TWO SYSTEMS ANYMORE.
GENERALLY PEOPLE ARE ALLOWED TO ACTUALLY REMOVE THEM BECAUSE WE DON'T EXPECT THE HOSE TO BE MAINTAINED AND THINGS LIKE THAT, EXCEPT IN VERY SPECIFIC OCCUPANCIES.
AND THEN THE CLASS THREE ON THE TOP, RIGHT? YOU HAVE THE TWO AND A HALF INCH HOSE VALVE FOR THE FIRE DEPARTMENT.
AND THEN BOTTOM LEFT, YOU HAVE THE INCH AND A HALF VALVE WITH THE OCCUPANT.
UTOPIA IS A PICTURE OF ONE OF THE HOTELS.
SO THIS IS A COMBINATION RISER, THE FEW DIFFERENT DEVICES ON IT.
BUT THE POINT IS, EVEN THOUGH IF YOU SEE ALL THAT TO GET WATER OUT OF THE STANDPIPE, THERE'S ONLY ONE VALVE THAT YOU NEED TO BE WATCHING.
AND THAT'S THE BOTTOM TWO AND A HALF INCH HOSE VALVE.
EVERYTHING ON THE TOP LEFT IS RELATED TO THE SPRINKLER SYSTEM BECAUSE IT'S A COMBINATION SUPPLY FOR SPRINKLER AND STANDPIPE, BUT WE NEED TO CONNECT A HOSE TO IT.
WE'RE JUST CONNECTING TO THAT STANDPIPE HOSE VALVE AND SPINNING THAT WHEEL.
TOP LEFT HAS A CONTROL VALVE, A CHECK VALVE, A FLOW SWITCH.
THAT'S ALL FOR THE SPRINKLER ZONE ON THAT FLOOR.
WE COULD GO THERE AND SHUT IT DOWN.
BUT PER STANDPOINT OF OPERATIONS, WE DON'T NEED TO MESS WITH IT.
EVERYONE'S PROBABLY HEARD OF PRESSURE REGULATING VALVES OR PRESSURE, REDUCING VALVES ON STANDPIPE SYSTEMS. IT WAS ONE OF THE MAJOR FINDINGS OF THE MERIDIAN FIRE IN PHILADELPHIA.
THERE ARE PRESSURE REDUCING VALVES IN THE TOWNSHIP, SOME OF THE OLDER BUILDINGS, UM, GENERALLY 25 OR 30 PLUS YEARS OLD AS THEY'RE RENOVATING THOSE BUILDINGS, WE'RE HAVING THEM TAKE THEM OUT, BUT IT'S SOMETHING TO BE AWARE OF THAT ANYTIME YOU GO UP TO A STANDPIPE POSE VALVE, YOU SHOULD BE CHECKING FOR THE PRESENCE OF A PRESSURE REDUCING VALVE.
IF THE SYSTEM'S CAPABLE OF OVER 175 PSI, THEY USED TO BE REQUIRED TO PUT THE PRESSURE REDUCING VALVE ON IT DOESN'T MEAN IT'S REDUCING IT TO 175 PSI COULD BE FAR LOWER THAN THAT, DEPENDING ON THE SETTING.
AND IF IT'S NOT MAINTAINED OVER THE YEARS, YOU MAY NOT BE GETTING MUCH WATER OUT OF IT AT ALL.
SO JUST MAKE SURE YOU'RE CHECKING FOR THE PRESENCE OF THAT.
THE DEVICE IS ACTUALLY LIMITING THE PRESSURE ON THIS IS THAT LITTLE KNOB ON THE WHEEL.
IN THIS CASE, IT'S VERY EASY TO BREAK THAT KNOB OFF AND ELIMINATE THE PROBLEM, BUT THEY'RE NOT ALL THAT SIMPLE.
SOME OF THEM HAVE TO BE INTERNALLY SET, UM, OR INTERNALLY CHANGED.
THE OTHER QUESTION IS, DOES IT LIMIT THE PRESSURE BY LIMITING HOW FAR THE WHEEL CAN OPEN? AND THAT'S CORRECT.
SO THIS STYLE IS LIMITING THE VALVE OPENING BY KEEPING THE WHEEL FROM TURNING TOO FAR OTHERS.
AND I DON'T THINK I HAVE A PICTURE OF IT, BUT, UM, THERE'S ACTUALLY INTERNAL DEVICES TO THE VALVE BODY THAT WE CAN'T MANIPULATE VERY EASILY.
IN THIS CASE, WE CAN ANY OTHER HOST VALVE OR STANDPIPE SO FIRE DEPARTMENT, CONNECTIONS, SUPPORT STANDPIPE OR SPRINKLER OPERATIONS, OR BOTH SOME CASES THEY EVEN DO FIRE HYDRANTS GET INTO A LITTLE BIT LATER, BUT THE THREE DIFFERENT WAYS THAT WE HAVE CAPS ON THE FIRE DEPARTMENT, CONNECTIONS IN OUR TOWNSHIP OR A LOCKING KNOX CAP, WHICH YOU'LL SEE THE VERY CLEARLY IDENTIFIABLE CAPS ON THE LEFT THERE.
AND YOU NEED THAT KEY ON THE RIGHT TO OPEN IT.
ALL THE TOWNSHIP COMPANIES HAVE BEEN PROVIDED WITH THEM, BUT IN THE EVENT YOU DON'T HAVE THEM.
LET ME KNOW AND WE'LL GET THEM OUT TO YOU.
IT WAS REQUIRED FOR A LITTLE WHILE HERE, BUT WE STARTED CONSIDERING THE BENEFIT VERSUS THE CHALLENGES OF THEM.
SO I DON'T KNOW THAT WE'LL CONTINUE WITH THEM BREAKAWAY STYLE.
THEY CAN BE PLASTIC OR METAL, BUT THE POINT IS YOU CAN HIT THEM WITH A SPANNER WRENCH.
YOU DON'T HAVE TO GO AND UNTHREAD THE NUT, JUST BREAK AWAY.
IF YOU HIT THEM WITH A SPANNER IN THE CENTER, THEY'RE NOTCHED UP.
I PUT A PICTURE IN, BUT MAYBE I DIDN'T.
UM, BUT IF YOU SEE THAT ONE IN THE MIDDLE THERE ON THE RIGHT SIDE, NOW THEY'RE JUST BREAKAWAYS.
THEY'RE VERY EASY IN THE BOTTOM THREADED PLUG, JUST LIKE ANY OF OUR HOSE CONNECTIONS JUST THREADS OUT.
[00:30:03]
AS FAR AS SIGNAGE GOES, THE FTC ITSELF HAS THAT RED RING AROUND IT.THAT'S GOING TO TELL YOU RIGHT ON IT, WHAT IT SUPPLIES.
SO IN THIS CASE, IT'S A SPRINKLER, ONLY THE TOWNSHIP.
WE'VE ALSO MANDATED THAT THEY INSTALL THE BIG RED SIGN ABOVE.
I THINK WE'LL GET INTO LATER ON.
THIS IS SPRINKLER ONLY, UM, I THINK THIS IS BAD.
THIS IS SHOWING THAT THERE'S THREE INLETS FOR IT.
SO SEE THE THREE ON THE BOTTOM.
YOU SEE THE SIGN ON THE TOP HAS THE THREE-WAY INLET AND A SPRINKLER.
LES IS A SPRINKLER SPRINKLER FTC, THIS SIGN SHOWING THAT IT'S A TWO INLET FTC SUPPLYING HYDRANTS AND A SPRINKLER.
THIS IS SHOWING SPRINKLERS IN A STANDPIPE ALSO WITH TWO INLETS AND THEN THIS IS SHOWING A STANDPIPE ONLY, AND THIS IS PROBABLY THE BEST EXAMPLE OF IT.
BUT THE RING AROUND THE FTC AT THE BOTTOM IS SHOWING DRY STANDPIPE.
SO THAT RINGS SHOULD ALWAYS BE TELLING YOU EXACTLY WHAT TO SUPPLY, WHETHER IT'S STANDPIPE AND SPRINKLER STANDPIPE, ONLY DRY STANDPIPE.
IN ADDITION TO THE BIG RED SIGN ABOVE, YOU'LL GET MORE DETAIL ON THAT RING AT SISTER.
UH, THE QUESTION IS, IS THAT STAINLESS, UM, THAT'S JUST A CHROME-PLATED FIRE DEPARTMENT CONNECTION BRING, CORRECT? YEAH.
SO THE POINT IS IT DOESN'T HAVE TO BE RED AND THAT'S CORRECT THAT THE SIGN ABOVE IS THE TOWNSHIP MANDATED ONE.
SO THAT HAS THE SHOWING THE TWO INLET FTC AS WELL AS A LITTLE HOSE REEL FOR THE STANDPIPE SYMBOL.
THAT'S ALWAYS GOING TO BE RED.
THE RING AROUND THE FIRE DEPARTMENT CONNECTION ITSELF COULD BE CHROME, COULD BE RED, COULD BE SOME FADED COLOR FROM 20 YEARS AGO, IT'LL BE IN BOSTON.
SO THE LETTERS WILL STAND OUT ALSO SPECIFIC TO THE TOWNSHIP OR TRUST PLACARDS.
SO THE RED ON THE WHITE BACKGROUND MEANS IT'S ROOF TRUST ONLY WHITE F ON A RED BACKGROUND IS FLOOR TRUSS.
AND THE WHITE R SLASH F ON THE RED BACKGROUND IS GOING TO BE A ROOF AND FLOOR TRUSS.
THIS IS REQUIRED IN ALL OCCUPANCIES AND UPPER PROVIDENCE.
SO IT'LL IDENTIFY THAT TRUST IS PRESENT AND WHETHER IT'S FLOOR TO CEILING, BUT IT'S NOT GOING TO TELL YOU IF IT'S WOOD OR IF IT'S METAL OR ANYTHING MORE DETAILED THAN THAT.
THE IDEA IS JUST THAT IT'S AN INDICATOR TO TELL YOU IT'S LIGHTWEIGHT TRUST.
YOU SHOULD KNOW THAT IT SHOULD FAIL FAIRLY EARLY IN A FIRE.
THEY'RE USUALLY LOCATED ABOUT THE FIRE DEPARTMENT CONNECTION SIGN.
IT KIND OF LOOKS LIKE A LITTLE HOUSE WHEN THEY'RE ALL STACKED ON TOP OF EACH OTHER, BUT THEY COULD ALSO BE LOCATED NEAR AN ENTRY DOOR ON OLDER BUILDINGS.
OR IF IT DOESN'T HAVE A SPRINKLER SYSTEM TO BE JUST NEAR AN ENTRY DOOR ONE AND TWO FAMILY DWELLINGS IN THE TOWNSHIP ARE NOT REQUIRED TO HAVE TRUST SIGNAGE.
SO IT SHOULD GENERALLY BE ASSUMED THAT IF YOU'RE GOING TO A MODERN CONSTRUCTION, SINGLE FAMILY DWELLING, THERE'S PROBABLY SOME TYPE OF TRUST IN THERE.
EXPECT IT TO FAIL PRETTY EARLY IN A FIRE.
THE QUESTION IS, IS IT WOULD TRUST AND LIGHTWEIGHT STEEL TRUST AND YES, IT'S, UH, IT'S JUST INDICATING TRUST.
SO IT'S, IT COULD BE LIGHTWEIGHT STEEL, IT COULD BE WOOD.
UM, IT'S NOT GOING TO GET MORE SPECIFIC THAN THAT.
IT'S JUST TELLING YOU THAT TRUST IS PRESENT.
ANY OTHER TRUST QUESTIONS OR SIGNED QUESTIONS? SO FIRE PUMPS, UM, TROOP TWO PRIMARY TYPES OF FIRE PUMPS, AN ELECTRIC DRIVE.
YOU'LL SEE THE BIG ELECTRIC MOTOR THERE OR A DIESEL ENGINE DRIVE.
YOU'LL SEE A BIG DIESEL ENGINE.
SO FOR ELECTRIC DRIVE FIRE PUMPS, THERE'S GOING TO BE THREE COMPONENTS TO IT.
IT'S JUST WHAT IT SOUNDS LIKE.
THERE'S THE DRIVER OR THE MOTOR, AND THERE'S THE PUMP BODY ITSELF.
ELECTRIC FIRE PUMPS MAY OR MAY NOT HAVE BACKUP POWER.
IT RELIES ON WHETHER THE POWER GRID IN THAT AREA IS CONSIDERED RELIABLE.
YOU MAY NOT THIS FIRE PUMP CONTROLLER ON THE LEFT.
THERE HAS TWO DIFFERENT DISCONNECTS ON IT THAT WOULD INDICATE THAT THERE'S PROBABLY BACKUP POWER, BUT SOMETIMES THE CONTROLLER WAS ORDERED A CERTAIN WAY AND NEVER GOT WIRED.
[00:35:02]
IF YOU RESPOND TO A FIRE, A PIPE BREAK OR SOME OTHER INCIDENT THAT CAUSES THE FIRE PUMP TO ACTIVATE AND DISCHARGE WATER.ONCE WE WENT THROUGH ALL THE STEPS BEFORE TO SHUT THE SPRINKLER SYSTEM DOWN, WE SHOULD BE GOING TO THE FIRE PUMP TO SHUT IT DOWN, UM, AND KIND OF MAKE IT OUT ON THE CONTROLLER.
THERE'S A GREEN BUTTON AND A RED BUTTON.
THE RED BUTTON WILL TURN THE FIRE PUMP OFF, BUT IT AUTOMATICALLY KICKS IT BACK INTO AUTOMATIC MODE.
SO IF YOU HAVEN'T SHUT DOWN THE LEAK OR WHEREVER THE WATER'S FLOWING, IT'S GOING TO TRY AND MAKE UP THAT PRESSURE AND TURN THE FIRE PUMP RIGHT BACK ON.
LET'S MAKE SURE THAT WE'VE SHUT THE PROBLEM OFF BEFORE YOU TRY AND SHUT THE FIRE PUMP OFF.
BUT THE QUESTION IS AS WITH THE OTHER APPLIANCES, DO WE WANT TO LOCK OUT TAG OUT ON THE FIRE PUMPS OR NOT? UM, IT'S GOING TO BE UP TO YOUR INDIVIDUAL SLPS HERE.
I REQUESTED LIKE ONE OF US GETS NOTIFIED IF A FIRE PUMP ACTIVATES OR HAS A PROBLEM WITH IT, AND IT'S GOING TO BE KIND OF A CASE-BY-CASE BASIS.
SO JUST GENERAL ELECTRICAL SAFETY, THE DISCONNECTS THAT YOU SEE ON THE RIGHT SIDE OF THE CONTROLLER, THEY SHOULD NEVER BE OPERATED UNDER LOAD.
IT'S NOT SOMETHING WE WANT TO MESS WITH FIRE PUMP MOTORS CAN GET PRETTY BIG.
THEY'RE NEARLY ALWAYS THREE PHASE AND GENERALLY HIGHER VOLTAGE.
SO ALWAYS MAKE SURE THE PUMP IS OFF.
WE REALLY SHOULDN'T EVEN BE TOUCHING THE DISCONNECTS, BUT IF FOR SOME REASON YOU HAVE TO MAKE SURE THE PUMPS ALL FIRST.
SO THE SECOND MOST COMMON FIRE PUMP IS THE DIESEL DRIVE.
YOU SEE THE CONTROLLERS A LOT SMALLER BECAUSE THERE'S NOT A LOT OF POWER COMING THROUGH THAT.
THE DRIVER IN THIS CASE IS THE DIESEL ENGINE AND THE PUMP LOOKS PRETTY MUCH THE SAME.
SO THESE LIVE IN FIRE PUMPS DON'T REQUIRE BACKUP POWER CAUSE THEY HAVE THEIR OWN FUEL SUPPLY.
THE ENGINES ARE SACRIFICIAL AND THEY'RE DESIGNED TO RUN UNTIL THEY EITHER RUN OUT OF FUEL OR THEY MECHANICALLY FAIL.
SO THIS IS ONE THAT WE REALLY WANT TO MAKE SURE IT'S NOT RUNNING FOR HOURS ON END.
AND PART OF THIS RESPONSIBILITY FALLS ON THE PROPERTY OWNER TO, UM, THEY'RE NOT GOING TO SHUT DOWN FOR AN OVERHEAT LOW OIL OR ANY OTHER CONDITION THAT OTHER ENGINE MIGHT SHUT DOWN FOR.
THE ONLY THING IT'LL SHUT DOWN FOR IS AN OVERSPEED CONDITION BECAUSE THAT CREATES SOMETHING UNSAFE.
SO ALL THE SAME STEPS THAT WE'VE TALKED ABOUT SHUT DOWN THE SPRINKLER BROWSER BEFORE.
AND THEN ALSO BASICALLY THE SAME AS THE ELECTRIC FIRE PUMP THAT YOU'RE JUST SHUTTING DOWN THE CONTROLLER USING THAT RED STOP SWITCH QUESTIONS ABOUT DIESEL OR ELECTRIC FIRE PUMPS.
THE QUESTION IS WHAT SIZE DIESEL TANKS THEY USUALLY HAVE? SO THE DIESEL TANK IS SIZED TO PROVIDE EIGHT HOURS OF RUNTIME AT A HUNDRED PERCENT PUMP CAPACITY.
THEY'RE ALWAYS GOING TO BE WELL GOT IN MODERN CODES.
IT'S GOING TO BE A DOUBLE-WALL TANK AND THEY CAN ACTUALLY ATTACH MONITORING TO IT FOR LEVEL IT TIES IN WITH THE FIRE ALARM SYSTEM.
NO, THE QUESTION IS ANY OF THESE IN PROPANE OR NATURAL GAS, PROPANE AND NATURAL GAS DRIVERS ARE NOT ALLOWED UNDER THE FIRE PUMP STANDARD.
THE ONLY OTHER POWER SUPPLY FOR THIS IS A STEAM TURBINE.
ANY OTHER FIRE PUMP QUESTIONS.
EVERYBODY'S FAVORITE FIRE ALARM SYSTEMS. TWO PRIMARY TYPES ARE CONVENTIONAL, WHICH IS A ZONE SYSTEM.
THAT'S WHEN YOU GET ZONE ONE ZONE TWO, WHATEVER IT CAN CONTAIN A TON OF DEVICES.
I FORGOT WHAT THE THRESHOLD IS, BUT I THINK IT'D BE UP TO LIKE A HUNDRED OR SO DEVICES PER ZONE.
THEN THE OTHER OPTION IS AN ADDRESSABLE SYSTEM AND THAT'S WHEN YOU'RE GETTING POLL STATION FRONT DOOR OR SOMETHING LIKE THAT.
THERE'S OTHER WAYS THEY CAN DO IT.
BUT THAT'S THE EASIEST WAY TO KIND OF REMEMBER THE DIFFERENCE BETWEEN THE TWO, BUT ADDRESSABLE.
EACH DEVICE HAS AN ADDRESS AND THE FIRE ALARM CONTROL PANEL IS PROGRAMMED WITH THE DESCRIPTION OF IT.
SO FOR THE ZONE SYSTEM, FOR US TO FIGURE OUT WHICH DEVICE ACTIVATED ON IT, WE COULD BE LOOKING THROUGH A WHOLE FLOOR OF DEVICES, REALLY FOR A SMOKE ALARM.
YOU'RE GOING TO BE PROBABLY LOOKING FOR A RED LIGHT.
THAT'S SOLID, BASICALLY, WHATEVER IT DOESN'T LOOK LIKE THE OTHER DEVICES FOR HEAT DETECTORS, IF THEY'RE, NONRESECTABLE, THERE'LL BE LIKE A DISC ON THE BOTTOM AND THAT DISC WILL HAVE FALLEN OFF AND BE MISSING.
BUT DIMENSIONAL SYSTEMS ARE DEFINITELY
[00:40:01]
TIME CONSUMING TO FIGURE OUT THE POINT OF ACTIVATION.WHEREAS ADDRESSABLE SYSTEMS THAT KIND OF SHOW US WHERE THE PROBLEM IS.
THIS IS A POINTLESS FOR, UH, AN ADDRESSABLE SYSTEM.
SO YOU CAN SEE THIS IS ALL STUFF.
A LOT OF IT'S THINGS THAT WE DON'T EVEN NECESSARILY EVER SEE, BUT IT'S ALL IN THAT FIRE ALARM PROGRAMMING.
SO THE FIRST THREE, FOUR FIRST FOUR POINTS UP THERE JUST ELEVATOR RELAY CONTROLS FOR ELEVATOR RECALL, UM, AND THERE'S TAMPERS AND THINGS LIKE THAT.
SO THE DEVICES THAT WE'RE GOING TO SEE ARE ONLY GOING TO BE ALARM POINTS USUALLY.
SO WE'RE GETTING WATERFLOWS, WE'RE GETTING PULL STATIONS LIKE THAT.
THIS IS ONE PAGE OF PROGRAMMING THAT PROBABLY COUPLE DOZEN MORE PAGES, DEPENDING ON HOW BIG THE BUILDING IS.
THERE'S THREE DIFFERENT TYPES OF SIGNALS THAT COME FROM A FIRE ALARM CONTROL PANEL VERSUS THE ALARM SIGNAL, WHICH WE'RE ALL PRETTY FAMILIAR WITH.
I MEAN, IF THERE'S A REASON TO BELIEVE AS A FIRE IN THE BUILDING, THE SPECIAL THE FIRE COMPANY AND NOTIFY THE PROPERTY OWNER OF THE ISSUE, SUPERVISORY CONDITION IS NOT GOING TO DISPATCH THE FIRE DEPARTMENT, BUT SOME KIND OF DEVICE MONITORED BY THE FIRE ALARM CONTROL PANEL.
IT COULD BE THAT A DUCT DETECTOR ACTIVATED AND SHUT DOWN AN AIR HANDLER.
IT COULD BE THAT A SPRINKLER CONTROL VALVE IS SHUT SOMETHING'S WRONG, BUT IT'S NOT REALLY THE FIRE DEPARTMENT'S PROBLEM.
IT JUST NOTIFIES THE PROPERTY OWNER TROUBLE CONDITION MEANS THERE'S SOMETHING WRONG WITH THE SYSTEM, WHETHER IT'S WIRING OR EQUIPMENT, THERE'S A SHORT CIRCUIT, SOMEWHERE, A GROUND FAULT, OUR LOSS BATTERY ISSUES.
AGAIN, WE'RE NOT GOING TO BE NOTIFIED OF IT.
IT'S JUST GOING TO BE THE PROPERTY OWNER.
WHEN A FIRE ALARM SIGNAL COMES IN THE CONTROL PANEL, DIALS A MONITORING COMPANY AND PROVIDES THEM WITH THE ACTIVATION POINT MONITORING COMPANY, THEN CALLS THE RADIO ROOM AND SAYS, THERE'S AN ACTIVATION.
WHEREVER THE MONITORING COMPANY COULD BE OUT IN KANSAS, OR IT COULD BE NEXT DOOR DOESN'T MATTER.
THEY HAVE A POINT LIST, DIAL IT OUT.
UM, THE CODE SAYS IT CAN ACTUALLY TAKE UP TO FIVE MINUTES FROM THE POINT OF ACTIVATION ON THE PREMISES, WATERFLOW, EMMANUEL POLE, SMOKE DETECTOR, HEAT DETECTOR.
THEY'RE ALL THE PRETTY COMMON ALARM SIGNALS.
WHEN WE SEE THE CONTROL PANEL, WE SHOULD SEE SYSTEM ALL NORMAL, BUT IT NEVER SAYS THAT WHEN WE GO OUT THERE, CAUSE THERE'S SOME KIND OF ALARM CONDITION, YOU'LL SEE THE ALARM INDICATOR LIGHT UP THERE AND YOU CAN SCROLL THROUGH AND FIGURE OUT THE, UH, POINT OF ACTIVATION.
WE USUALLY SILENCE THE ALARM PRETTY QUICKLY AFTER WE GET THERE.
CAUSE WE DON'T WANT TO HEAR IT.
UM, ONCE WE DETERMINED THERE'S NO PROBLEM, MOST ALARMS, YOU CAN SILENCE.
THERE ARE CERTAIN ONES THAT THE CODE SAYS YOU'RE NOT SUPPOSED TO BE ABLE TO, AND THOSE ARE WATERFLOW SIGNALS.
SO IF IT'S ANY KIND OF SPRINKLER ACTIVATION CAUSING A WATERFLOW SIGNAL, YOU MAY NOT BE ABLE TO SILENCE IT.
IT'S NOT A PROBLEM WITH THE ALARM PANEL.
IT'S ACTUALLY DOING WHAT IT'S SUPPOSED TO, BUT THAT'S WHERE IT COMES INTO SHUTTING DOWN THE RISER AND GETTING PRESSURE OFF OF THE LOW SWITCHES AND THAT KIND OF THING THAT WILL ALLOW US TO RESET IT AND GET THE NOISE TO STOP FIRE ALARM ENUNCIATOR PANEL.
IT'S JUST A MINI CONTROL PANEL.
SO YOU'LL SEE THESE USUALLY THE FRONT DOOR, LIKE A VESTIBULE SOMEWHERE IT'LL REQUIRE A KEY OR A DECODE TO OPERATE IT.
YOU CAN GENERALLY RESET IN SILENCE, EVERYTHING FROM THE ANNUNCIATOR PANEL.
YOU DON'T HAVE TO GO TO THE FIRE ALARM CONTROL PANEL.
IF IT DOESN'T WORK AT THE ENUNCIATOR PANEL, THEN GO FIND THE FIRE ALARM ROLL BACK.
WELL, THE COMMON ONES WE GO OUT FOR MANUAL PULL STATION.
THEY DON'T ALL LOOK LIKE THAT, BUT THAT'S ONE OF THE MORE COMMON ONES.
WE ALWAYS HAVE TO RESET THE MANUAL POLL STATION BEFORE WE CAN RESET THE FIRE ALARM PANEL.
SO OPEN THE MANUAL POLL STATION UP, THERE'S A LITTLE TOGGLE SWITCH IN THERE.
IT'LL SAY EITHER ACTIVATED OR NORMAL.
SO WE HAVE TO PUT THAT SWITCH BACK TO NORMAL, CLOSE IT BACK UP AND WE CAN RESET THE SYSTEM.
NOT ALL OF THEM HAVE A SWITCH IN THERE.
SOME OF THEM HAVE A MOMENTARY PUSH BUTTON.
UM, SOME OF THEM HAVE A DIFFERENT LOOKING SWITCH, BUT IN ANY EVENT, YOU'LL HAVE TO OPEN IT UP TO RESET IT.
SOME REQUIRE A KEY, SOME REQUIRE AN ALLEN WRENCH, SOME REQUIRE A SCREWDRIVER.
SO THEY'RE ALL A LITTLE BIT DIFFERENT, JUST ALWAYS GOOD THINGS TO HAVE IN YOUR POCKETS OR YOUR FULL KITS.
I MEAN, EVERYONE HERE IS PRETTY MUCH A PRO AT ALARM SYSTEMS. LET'S SEE ENOUGH OF THEM.
ALL RIGHT, KITCHEN SUPPRESSION,
[00:45:04]
COMMERCIAL KITCHENS ARE REQUIRED TO HAVE SUPPRESSION, BRIARS, GRIDDLES, RANGES, SALAMANDERS, WHATEVER THEY ALL NEED.SOME KIND OF SUPPRESSION BASED ON A WET CHEMICAL.
IT'S THE SAME CONCEPT AS A CLASS K FIRE EXTINGUISHER.
IT OPERATES ON A PRINCIPLE CALLED SUP PONTIFICATION.
IT ALMOST MAKES SOAP OUT OF THE GREASE TO FORM A BARRIER.
SO IT DOESN'T LET ANY MORE VAPORS THROUGH TO BURN.
IT'S A SPECIFIC TO RESTAURANTS BECAUSE OF THE HIGH TEMPERATURES THEY USE AND THE TYPES OF COOKING FATS.
THEY USE THERE'S NOZZLES ABOVE EACH APPLIANCE IS BEING PROTECTED, A NOZZLE OR MORE NOZZLES IN THE PLENUM AND THEN NOZZLES UP IN THE EXHAUST DUCT.
SO WHEN THE SYSTEM ACTIVATES, WHICH WILL BE EITHER DUE TO A FEASIBLE LINK MELTING BECAUSE IT DETECTS A FIRE OR FROM A MANUAL POLL STATION WOULD JUST SEE ON THE RIGHT SIDE OF THE SLIDE, EITHER ONE OF THOSE CAN ACTIVATE THE SYSTEM.
IT DUMPS ALL THE NOZZLES AT ONCE.
IT'S NOT JUST LIKE A SPRINKLER SYSTEM WHERE ONLY THE ONE THAT'S AFFECTED BY FIRE.
THIS, THIS DUMPS THEM ALL AT THE SAME TIME, IT'S SIMULTANEOUSLY WILL SHUT A GAS VALVE, TURN OFF ANY KIND OF FUEL TO THE COOKING APPLIANCES.
IT'LL KILL ELECTRIC AS WELL UNDER THE HOOD AND SET OFF THE BUILDING FIRE ALARM.
THE PULL STATION SHOULD NEVER REALLY BE ACTIVATED ACCIDENTALLY BECAUSE IT LOOKS A LOT DIFFERENT FROM THE NORMAL ONES ANYONE DOES DO IT.
IT'S A VERY EXPENSIVE MISTAKE.
ANYBODY HAVE KITCHEN SUPPRESSION QUESTIONS, RIGHT? SO ANY FIRE PROTECTION SYSTEM CAN FAIL FOR ANY NUMBER OF REASONS.
THE COMMON ONES ARE A LACK OF MAINTENANCE.
THEY'RE NOT UPDATED FOR THE HAZARD.
WHEN IT COMES DOWN TO, UH, AN OFFICE MOVES OUT AND SOMEBODY WAS A CLOTHING SHOP IN THERE, THEY'RE CHANGING THE HAZARD CLASS.
THE SPRINKLER SYSTEM SHOULD BE UPDATED TO ADDRESS THAT, BUT IT ISN'T ALWAYS.
AND IF THEY DON'T GO THROUGH THE PERMIT PROCESS, REPAIRS ARE MADE IMPROPERLY SOMETHING COULD BE KEPT OFF OR A VALVE COULD BE LEFT, CLOSED ALTERATIONS ABOUT PERMITS.
WE TALKED ABOUT, UH, THE ADEQUATE WATER SUPPLY.
THAT'S A CONCERN FOR US AROUND HERE.
AS DEVELOPMENT NEEDS TO OCCUR, WE'RE SEEING LESS WATER PRESSURE IN THE CITY MAINS FOR LACK OF A BETTER TERM OF THE PUBLIC WATER SUPPLY.
SO WHAT MAY HAVE BEEN GOOD 10 YEARS AGO FOR THE SPRINKLER SYSTEM? ISN'T GOOD ENOUGH ANYMORE.
A FEW PLACES THAT HAVE PUT IN FIRE PUMPS AND THINGS LIKE THAT CONTINUE TO OCCUR, BUT WE SHOULD KNOW THAT IF IT'S AN OLDER BUILDING AND EVEN IF IT HASN'T CHANGED IN YEARS, WE MAY NOT BE GETTING THE WATER OUT OF THE SPRINKLER SYSTEM THAT WE THOUGHT MIGHT BE GOOD TO DO.
SO THE PRESSURE ON THAT, SO WE TRY TO KEEP IT SHORT AND SWEET TONIGHT.
UM, THAT DOESN'T MEAN YOU CAN'T ASK QUESTIONS.
SO EITHER NOW, OR IF SOMETHING COMES UP LATER, JUST EMAIL ONE OF US.
ANY QUESTIONS ABOUT THE MOST BASIC FIRE PROTECTION SYSTEM PRESENTATION? THE QUESTION WAS THE KITCHEN SUPPRESSION SYSTEM.
DOES IT SHUT DOWN THE DUCT WORK? UM, I DIDN'T REALLY GET INTO IT, BUT THE, WHEN THE KITCHEN SUPPRESSION ACTIVATES, IT'S GOING TO SHUT OFF THE MAKEUP AIR AND LEAVE ON THE EXHAUST AIR.
SO DURING NORMAL COOKING OPERATIONS, BECAUSE SO MUCH AIR IS BEING EXHAUSTED, IT BRINGS IN MAKEUP AIR.
SO IT DOESN'T CREATE A VACUUM IN THE SPACE.
WE DON'T WANT TO FEED THE FIRE WITH AIR, SO IT SHUTS OFF MAKEUP, BUT IT KEEPS THE EXHAUST GOING TO GET THE SMOKE AND OTHER FIRE OUT.
THE QUESTION WAS, HOW LONG HAS THE TRUST SIGNAGE ORDINANCE BEEN ENACTED? UM, I BELIEVE IT WAS 2003 OR 2005 THAT IT WAS IMPLEMENTED.
THERE WAS A BIG FIGHT FROM HOME BUILDERS, OTHER TRUSTS INDUSTRY, PEOPLE THAT THEY DON'T WANT THE SIGNAGE BECAUSE THEY FEEL LIKE IT'S BEING TARGETED OR SOMETHING.
UM, BUT WE WERE ABLE TO GET IT THROUGH SOMEHOW BEFORE MY TIME.
THE QUESTION IS, ARE THERE ANY CLEAN AGENT OR HALON OR FM 200 SYSTEMS IN ANY FACILITIES IN THE TOWNSHIP? THERE ARE TONS OF THEM.
UM, SO THIS IS SOMEWHAT OF A WORK IN PROGRESS AND IT'S ALSO LIKE, YOU KNOW, HOW MUCH DO PEOPLE WANT TO HEAR ABOUT CERTAIN THINGS,
[00:50:01]
BUT CLEAN AGENT IS, UH, IT'S INSTALLED GENERALLY IN SERVER ROOMS. UM, ANYWHERE THAT THEY'RE SENSITIVE ELECTRONICS, THEY DON'T WANT WATER SPRAYING ON IT.THEY DON'T WANT A DRY CHEMICAL FIRE EXTINGUISHER GETTING DUMPED ON AT WORK DAMAGE, SENSITIVE ELECTRONICS.
SO FM 200 OR CLEAN AGENT IS THE FIRST SUPPRESSION SYSTEM IN THE LINE OF DEFENSE.
IF THAT DOESN'T WORK, IT'S STILL USUALLY HAS TO BE SPRINKLERED AS A BACKUP.
IF THEY'RE PRESENT IN A BUILDING AND THE BUILDING HAS A FIRE ALARM SYSTEM THAT CLEAN AGENT SYSTEM IS GOING TO BE TIED INTO IT.
IT IS GOOD TO TALK ABOUT BECAUSE SOME OF THOSE DISPLAYS OXYGEN OR THEY CAN ACT AS AN .
SO IF IT'S BUILDING A SHOWING THAT THE ALARM SYSTEM SHOWS THAT THAT SYSTEM ACTIVATED DON'T GO CHARGING INTO THE ROOM, IT VERY WELL BE THAT IT'S NOT A GOOD ENVIRONMENT FOR US TO BE, BUT THERE ARE PRESENT.
THERE'S QUITE A FEW OF THEM IN THE TOWNSHIP FM, OR THE QUESTION IS WHAT DOES FM 200? WHAT DOES THE EXTINGUISHING AGENT, THE EXTINGUISHING AGENT VARIES DEPENDING ON MANUFACTURER? I DON'T FM 200, I BELIEVE AS A STANDARD.
SO IT WAS A REPLACEMENT FOR HALON.
HALON USED TO BE THE GREATEST SUPPRESSING OUT THERE.
AND THEN IT TURNS OUT IT WAS KILLING THE ATMOSPHERE.
SO YOU WERE ALLOWED TO USE IT IF YOU HAD IT UP TO A CERTAIN POINT AND YOU CAN'T MAKE IT ANYMORE.
SO FM 200 CAME OUT AS THE MORE ENVIRONMENTALLY FRIENDLY SYSTEM.
BUT EVEN THAT THEY'RE LOOKING AT SOME OF THE CHEMICALS IN THIS NEW STUFF AND SAYING, WELL, THAT'S NOT SO GOOD EITHER.
SO THERE'S ANOTHER STANDARD ON THE HORIZON TO ADDRESS THAT.
SO THE ANSWER IS, I CAN'T TELL YOU WHAT IT IS.
UM, AS FAR AS CLEAN AGENTS GO, IT COULD BE CO2.
IT COULD BE NITROGEN THEY'RE CONSIDERED.
UM, BUT THEY'RE USUALLY A PROPRIETARY MIX.
IF IT'S A SPECIALTY EXTINGUISHING SYSTEM LIKE THAT, YOU SHOULD BE BREATHING FROM YOUR AIR CYLINDER AND HAVE A METER WITH YOU.
THE ROOMS THAT IS CONTAINED IN HAVE TO BE SEALED.
SO THERE'S A PRESSURE TEST THAT'S DONE BEFORE THEY INSTALL THE SYSTEM.
UM, AND THEN ONCE THEY'RE INSTALLED, THERE'S GOING TO BE SIGNAGE ON THE DOORS.
THERE'S GOING TO BE SEPARATE STROBES THAT INDICATE THAT THE SYSTEM IS ACTIVATED.
IT'S NOT, IT'S GOING TO BE VERY DIFFICULT TO ACCIDENTALLY WALK IN THERE, BUT STILL PAY ATTENTION.
CAUSE WE'RE USED TO WALKING IN WHEN THE ALARMS ARE GOING.
SO THE QUESTION IS, ARE WE DOING INDIVIDUAL KNOCKS BOXES? OKAY.
SO YEAH, THE QUESTION IS, ARE WE DOING INDIVIDUAL KNOX BOXES ON BUSINESSES OR ARE WE CONTAINING THEM ALL IN THE SPRINKLER ROOM? SO WHAT WE'VE MOVED TO OVER THE LAST, I DON'T KNOW, EIGHT OR 10 YEARS, ANY KIND OF STRIP MALL OR MULTITENANT BUILDING.
SO THINK, I CAN'T SAY NAMES, BUT BIG SHOPPING MALL UP THE STREET.
UM, AND OTHER STRIP MALLS THAT ARE MORE MODERN, IT'S GOING TO BE A KNOX BOX ON THE EXTERIOR OF THE BUILDING.
AND THEN WITHIN THE SPRINKLER ROOM, THERE'S A KNOX VAULT THAT CONTAINS THE REMAINING PENDANT SPACES AND ANYBODY ELSE.
GET IN TROUBLE IF WE DON'T GO ALONG.
IF YOU GUYS DON'T HAVE QUESTIONS, UM, OR IF YOU THINK, THINK OF SOMETHING LATER, EMAIL ME, EMAIL MIKE.
UM, IT WAS JUST MEANT TO BE A QUICK OVERVIEW.
IF THERE'S SOMETHING YOU GUYS WANT TO HEAR MORE ABOUT LATER, LET US KNOW.
OKAY, THE QUESTION IS, ARE WE STILL GOING WITH TWO, TWO AND A HALF OR THREE AND CHOSE LINES AT 150 PSI FOR FIRE DEPARTMENT CONNECTIONS AND YES.
UM, ESPECIALLY FOR SPRINKLERED BUILDINGS.
SO STANDPIPES GOT A LITTLE FUNKY BECAUSE WE HAD TO FIGURE OUT ELEVATION LOSS AND FRICTION LOSS AND WHAT KIND OF NOZZLE EVERYBODY'S USING AND THAT KIND OF THING.
BUT TO SUPPORT A SPRINKLER ONLY SYSTEM IN A BUILDING 150 PSI TO START AT THE FIRE DEPARTMENT
[00:55:01]
CONNECTION, THERE WAS A SLIDE I WAS GOING TO PUT IN HERE ABOUT IF THERE'S A FOAM SYSTEM AT THE FACILITY, BUT THEY'RE NOT VERY COMMON.SO THE ONLY TIME YOU CAN GET INTO TROUBLE WITH A FIRE DEPARTMENT, CONNECTION IN A SPRINKLER BUILDING IS WHEN THERE'S A FOAM SYSTEM.
BECAUSE THE, JUST LIKE THE DOCTORS THAT WE USE FOR FOAM PAILS, THEY REQUIRE A CERTAIN PRESSURE AND VOLUME TO OPERATE PROPERLY TO GET THAT PROPORTION, CORRECT, SAME DEAL WITH A FIXED SYSTEM IN A BUILDING.
SO IF YOU PUMP THAT AT TOO HIGH OF A PRESSURE BEYOND THE SYSTEM DESIGN, YOU COULD END UP MESSING UP THAT FOAM BALANCE AND DOING MORE HARM THAN GOOD.
IT WASN'T WORTH PUTTING IN THE PRESENTATION BECAUSE IT'S SUCH A SMALL SHOT OF US ACTUALLY DEALING WITH IT, BUT GENERALLY 150 PSI AT A FTC FOR A SPRINKLER.
WELL, AREN'T YOU GUYS THINKING ANYTHING LATER ON? JUST LET ONE OF US KNOW.
