So my take is and always has been, is to use FOG. Reason being it gives you some versatility for hydrolic vent, exposure protection, etc. HOWEVER the deal with using said nozzle is DISCIPLINE! The nozzleman has to keep it on straight stream during operations 98% of the time. That is the rub and I see it all the time is the 3/4 fog attack nonsense. Even considering the specific focus on glyphosate plus dicamba mixtures and air induction nozzles, the results presented in this work showed that the use of V as a factor to analyse the.

After some discussions about the use/misuse of fog nozzles, I decided to become more familiar with this topic.
I recently finished reading "The safe an effective use The Safe and Effective Use of Fog Nozzles fog nozzles - research and practice" (by John E. Bertrand, John D.
Wiseman) and trying now to get the most important lessons out of this book into a training (only theory, practice will follow). Product Description: Finally, a book that describes the research, both historical and recent, which leads to the proper use of fog nozzles.
The Safe and Effective Use of Fog Nozzles: Research and Practice suggests the most appropriate types of fires, situations, tactics, and strategies that lead to the greater and better utilization of this.

Wiseman Consulting, Firefighters typically use fog nozzles with hand held hoses. Water travels through these hoses at rates that may range from 60 to gallons ( to liters) per minute. The force of the water hitting the special diffusing element within the fog nozzle turns droplets into vapor-like particles.
The Safe and Effective Use of Fog Nozzles, Research and Practice. John Wiseman. 01. Tips of Self-Help in Disasters (Chinese Edition) by John Wiseman and a great selection of related books, art and collectibles available now at Smooth Bore Nozzles.
Smooth bore nozzles, also known as solid bore nozzles, are the most basic type of fire nozzle - both in design and function. They produce a solid stream, providing maximum reach and penetration. Fog Nozzles. Fog nozzles produce a similar stream to smooth bore nozzles, but require a higher inlet pressure.

They confirmed that, whilst not suitable to all situations, 3D tactics most certainly proved effective and firefighters would receive training in the use of 3D water-fog as an option.
It is difficult to achieve true comparisons in aquired structures as each fire burns differently with varying amounts of fuel-load and ventilation profiles. Dust cover is intact; pages are clean and are not marred by notes or folds of any kind.

Published by Fire. Comparison of fog nozzle effects Creating high-pressure fog systems that use pure water instead of consuming glycol based substances or liquid nitrogen is the Koolfog difference.
Each fog effect is powered by the same Koolfog high-pressure pump system, but using different nozzles for. Whether you need fire nozzles, fire fighting valves, monitors or the latest technology in vehicle electronics, Akron Brass has a large selection to meet your unique application.
Our fire fighting equipment is safe and effective for your emergency situation. Note that when stepping up to the 1 1/8-inch smooth bore tip the horizontal range difference is about 10 feet, but also note the vast increase in flow for the same nozzle reason that 50 psi is a good operating nozzle pressure for handline smooth bore tips(and fog nozzles)is that it gives the firefighter an effective reach of around Location: Theo Lane Pleasant Hill, CA, United States.
Basic fog nozzle - An adjustable-pattern fog nozzle in which the rated discharge is delivered at a designated nozzle pressure and nozzle setting.
Constant gallonage fog nozzle - An adjustable pattern fog nozzle that discharges at a constant rate throughout the range of patterns from a straight stream to a wide fog at a designed nozzle pressure. We use 2 inch hose, but the concept is still valid with 1 3/4" hose.
The choice of whether to use fog or smooth bore is entirely up to the nozzle operator. They can spin off the fog tip and flow GPM with the smoothbore, or use the combo tip on either straight stream or fog at GPM.
I think you can make valid arguments for either nozzle. ScaryProducts: Decorations: Fog Machine Safety: Fog Machine Safety. Using a fog machine on Halloween can be one of the coolest and effective ways to create a scary and realistic Halloween setting.
They can be used to make your front yard graveyard into the most frightening yard in the neighborhood, but they can also create some very real dangers if not used properly.
Combination fog, Constant pressure, (Automatic) type spray nozzles should not be used for standpipe operations because many of this type require a minimum of psi of pressure at the nozzle inlet to produce a reasonably effective fire stream. In standpipe operations hose friction loss might prevent the delivery of psi to the nozzle.
Our fog nozzles will produce a high quality fog or mist depending on the operating pressure and the orifice size of the fog nozzle. If used at higher pressures a micron droplet can be achieved. Fog nozzles are typically used for greenhouse, people & livestock cooling, produce, habitat and industrial humidification, concrete curing, dust.
able fog nozzles must be turned off for the operator to adjust the flow. the fog pattern widens, the nozzle reaction decreases and the nozzle is easier to handle.
nozzles are more difficult to handle than smooth bore nozzles. We typically use smooth bore nozzles on our initial attack lines on my engine. Other companies use fog nozzles or even the "vindicator" nozzle (wich is a low pressure nozzle that has a high GPM flow but no reach and penetration).
It is usually up to the company commander which nozzles they wish to run and how the hose is loaded. relatively small amount of fog stream can be shot into the area (the area is sealed tight), and the water will turn into steam smothering the fire.
this is called the indirect attack method. Find here online price details of companies selling Fog Nozzles.

This conversation has been a topic within the fire service since the introduction of the fog/combination nozzles in the ’s.
Although there are positives to both pieces of equipment, I believe that the department needs to make a decision on which nozzle to use for a.

Crane & Julian L. Williams. Tulsa, Okla.: PennWell. (TH C73 ) The Safe and Effective Use of Fog Nozzles: Research and Practice by John E. Bertrand and. A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its lly designed fog nozzles (with no stream adjustment.
Our industrial fog nozzles were created to handle the rigors of industrial needs in refineries, chemical plants, office complexes and other on-site situations.
Several different materials are available to suit every need, and most nozzles are U.L. listed and/or FM approved. The fog nozzles with the electrical specification are designed to be used on class “C” hazards and utilize only fog.
New effective and clean fire extinguishing agent are developed for protecting the machinery room, electronic room, computer room and submarine. It is reported that water mist fire suppression system (WMFSS) would use very small amount of water to extinguish a fire.
System components include water source, water pump, pipe works, and nozzles. System. Ultrasonic fogging nozzles are twin fluid type spray nozzles, usually using compressed air and water to create a finely atomised water droplet, typically this nozzle range produces droplets from 3 to 10 micron.
This ultra-fine droplet is created through its unique nozzle design compressed air passes through the nozzle at high velocities and. (/3 X 33,) Examples of proper use of the full fog: Personal protection in a flashover or explosion To drive away, or control flammable vapors or sprayed fuels To clear smoke from an enclosed space To force fresh air to victims Radiant heat protection Exposure protection Examples of improper use of full fog: Disturbing the thermal balance.
Similar results were obtained for a 12% H2O2 solution, albeit that H2O2 was less effective compared to PAA, requiring 60 min to reach 3-log reduction when applied as a fog, with an estimated. Sanitation Best Practices. Nozzles are available to alter the spray pattern for varying cleaning jobs.
An alternative to a central system is individual hose stations. These stations have a supply of hot and cold water or steam injection for creation of hot water.
