Fire season is coming to Northern Cali shortly, as the seasonals are on boarded. @CAL_FIRE @Cal_OES two of the world leaders in wildfire mitigation & control, have a lot of work to do getting staffing and preparation up, basically year around now. @IAFFofficial @forestservice
Firefighters at scene of a 1/4 acre vegetation fire North of Oroville off of Coal Canyon Rd. Firefighters have stopped forward progress, no threat to structures, no injuries and cause under investigation. Firefighters will be at scene 1-2 hours to get full control. #Creekfire

Nothing to see here move along.... (This is actually pretty insane)
HISTORIC WARMTH IN ICELAND Arguably the most extreme event in European history Temperature reached an insane 20.3 at Gagnheiði 950m asl ! previous monthly record was 12.9C broken by 7.4C ! European all time record ! 20.3 Stykkishólmur monthly record (por 1885-)

HOT Workshop Engine Company few spots left in these time slots. @FDICevent Monday, April 7th 1- 5pm Tuesday April 8th 8-12pm & 1 -5pm Spend less & get more performance with your next Engine build. Spec & layout dicates strategy and tactics on the fireground. @IAFFofficial

2019 the first year TRU ID 2.25-inch hit the streets. It is now one of the most popular hose specs for the 265gpm@50psi flow. Charge weight saving of 90 pounds vs the bloated nominal 2.5-inch. Make flow & move large lines 3 person possible. @IAFFofficial @850fireman @CAL_FIRE
As part of our program @HROC We tested 2.25 Hose 1 1/16 tip @ 50 psi = 240 GPM flow. @CFTactics @Hydrant2Nozzle

Balded Pattern, has demonstrable positive impact in distal room more than a straight or solid stream. Hen https://t.co/oQ2EzK3cRG Kyle Romgus clearly talks about this superiority on Episode 77 on Multiple Call Podcast. https://t.co/QrZWyvLWVR

Thermal Rebound Drill: In each live fire training we conduct, we include a thermal rebound drill to demonstrate the importance between knock back and knock down. In this video, we demonstrate the HEN nozzle starting with a short burst with a straight stream, then a short burst

This is why this man is disrupting Silicon Valley, Wall Street and US politics. $PLTR *you ain’t seen nothing yet.

Stream geometry is extremely important as is GPS per square foot. It is a waste to have a single dot, too concentrated, reliant to surface deflection. Leading to weak suppression distribution, imagine a 7/8 solid tip or a fog pattern, both weak compared to Blade. @fireengineering

$PLTR is ready NOW. AI, productivity, supply chain, and national security issues are pressing NOW. No need to wait years like $TSLA or $AMZN for massive growth. Palantir’s development is complete and the whole planet needs it NOW.

Swipe right for entry to life/search, less fatigue & motion, concentrated edge pick up, a full knock down all ext. surfaces.. porch, walls, ceiling, roof boards, load bearing posts. KISS the Blade Pattern makes fire stream dynamics better.@fireengineering @IAFFofficial @FSRI_org

All major railroads will provide free training for response to Locomotive fires. @fireengineering @IAFFofficial @FSRI_org All it takes is a phone call and some networking from your training division. Diesel Electric locomotive fires are unique learn basics of safe suppression.

Retired firefighter Tammi Callahan was prepared when she was evacuated from the #shellyfire because she had been working on her defensible space for a decade. #fortjones

Run stats for June 25, 2024: • 273 total calls for service created for the #OFD • 199 were EMS related • 25 were FIRE related- (3 confirmed encampment fires) • 22 were miscellaneous fire responses • 27 were MACRO responses Thank you B Shift Crews and Dispatchers!

I am curious will metrics around, suppression of structural fires related to application of water be captured. Should we be front loading all of our fire suppression in the vast majority of fires. @fireengineering @smokedaddy5 @CftFire @usfire @HenNozzles @IAFFofficial#tankfirst
Tune in tomorrow to learn more about the new National Emergency Response Information System (NERIS)! Save the date for National Fire Data Week set to take place June 23-29 where we will highlight what NERIS is, its value proposition, why to transition, and how to get #NERISready.

Seeing should be believe. @FDICevent @fireengineering @IAFFofficial A Bladed pattern is a major advancement, speeding suppression, by placing large droplets in copious amounts on walls ceilings, floors, fuel packages & within gases in a more effective manner=Easier @HenNozzles

What is now possible with dissociation of Nozzle Pressure (Volume, Reaction Force, Velocity) and back pressure is truly remarkable for Handline Attack Package design. A back pressure increaser makes things possible that just where not before. @FDICevent @fireengineering

The TURBO is an absolute win for the fire service. Let's be frank the vast majority of the North American fire service is light staffed on arrival.

Love the A jack spread on a Seagrave Tiller..too many want a crane, not speed and placement. TDAs are ladder tenders even the main should focus on that. They are ingress machines, now how about a Tower a every other battalion? Four quadrants of the city? @dcfireems @DCFDKelleher
Working Fire on Box 9826 • 1600 block of Gainesville Street, SE #DC • The @dcfireems No. 32 Engine Co. reported a 3-story apartment building and smoke showing from the front. The No. 15 Engine Co. reported fire showing in the rear • #DCFD #WorkingFire
