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)

[Extreme Temperatures Around The World @extremetemps]

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

Spend less & get more performance with your next Engine build. Spec & layout dicates strategy and tactics on the fireground.

@LtRayMack @hroc @CFTactics HEN's Force Blade or Tip 250gpm@45psiNP@89lbsRF with 75psi back pressure in the hose, is going to make 2.15 to 2.3 inch hose sing the standard real large flow 250gpm+ massive flow & move on the table without the need for a lot kink minding @HenNozzles @LtRayMack @IAFFofficial

@SenSchumer @allinwithchris Thanks for causing WW3 ... do not stand in the way of Trump. The sooner he is allowed to self destruct the better. Your position is the same Appeasement that chamberlain suffered. WTF is wrong with you.

[Dennis LeGear @Hydrant2Nozzle]

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

[Ray McCormack @LtRayMack]

As part of our program @HROC We tested 2.25 Hose 1 1/16 tip @ 50 psi = 240 GPM flow. @CFTactics @Hydrant2Nozzle

[Dennis LeGear @Hydrant2Nozzle]

@NorwegianRoad @iamtomnash @iamtomnash I am also curious on this one. It would seem re balancing would be necessary now if that is part of your investment strategy.

[Dennis LeGear @Hydrant2Nozzle]

@OaklandFireCA MO...?

[Dennis LeGear @Hydrant2Nozzle]

@iamtomnash So true

[Dennis LeGear @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 @fireengineering @IAFFofficial

[AndyStarnesFire @KTFBurnsDC]

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 with the blade pattern. Both short bursts cool the overhead briefly but we see the return/rebound.

It is when we increase the duration of flow with the blade pattern that we see a full stop of convection currents while we are flowing. However, when we stop flowing we see the thermal rebound as we have not reached the seat of the fire yet.

Our last demonstration, we use the vertical blade pattern and aim at the door (instead of the ceiling). The result? IT CRUSHES THE FIRE ROOM!.

These demonstrations show the importance of a guided and properly flowed stream.

Thanks for your support!

*you ain’t seen nothing yet.

[Dennis LeGear @Hydrant2Nozzle]

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

[Ray McCormack @LtRayMack]

How can you be against being better? HEN 160 in action.

[Etienne Breton @etienne_breton]

$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.

[Dennis LeGear @Hydrant2Nozzle]

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.

@CALFIRESKU @HenNozzles Initial Attack is where the Blade Pattern has greatest possible ROI is in that moment the first 24 hours, equipment spec matters. Wildland firefighting is like a Orchestra, in many ways. Best equipment possible with training and organization, SKU is a great example.
