WHY are so many FIREFIGHTERS totally against/closed minded towards the       SOLID STREAM?  I love BOTH!!  I like options!! I like to have the chose based on fire conditions and extinguishment needs.  SOLID STREAMS/SMOOTH-BORE nozzles have been proven to be very reliable and effective on the fire ground for longer than anyone still involved in fighting fires. So study history and have options!!!!!!!  SORRY there is no DEBATE.

Choosing Between Smoothbore and Fog Nozzles: Key Considerations

When selecting a nozzle for interior firefighting, the choice between a smoothbore and a fog nozzle can significantly impact performance and safety. Here are the core arguments for each option:

Advantages of Smoothbore Nozzles

1. Penetration and Reach: Smoothbore nozzles are renowned for their ability to deliver a concentrated stream of water with impressive penetration and distance. This feature is critical for reaching the seat of the fire quickly, especially in environments where high pressure is required.
2. Consistent Flow Rate: They provide a stable Gallons Per Minute (GPM) output, which can be crucial in ensuring an effective and steady firefighting effort.
3. Lower Operating Pressure: These nozzles generally require less pressure to operate efficiently, reducing nozzle reaction and making it easier for firefighters to handle the hose.

Advantages of Fog Nozzles

1. Versatility: Fog nozzles offer a range of spray patterns, from a narrow straight stream to a wide fog. This adaptability allows firefighters to adjust the output based on the immediate needs of the situation, such as indirect attack or rapid heat absorption.
2. Cooling and Protection: The wide spray pattern of a fog nozzle can absorb heat rapidly and provide a cooling shield for firefighters, especially when operated in confined spaces.
3. Gas Entrainment: By generating a fog pattern, these nozzles can entrain significant volumes of gases, potentially pushing smoke and combustion products away from advancing hose lines.

Considerations and Challenges

• Steam Production: While the fog pattern can be beneficial, it can also generate large amounts of steam, which might pose hazards in poorly ventilated areas or if crew members become surrounded by steam.
• Situational Dependency: The best choice often depends on specific fire conditions. For example, a confined space might benefit from the cooling effect of a fog pattern, provided that ventilation is adequate to manage steam.
• Combination Options: Some modern nozzles offer combination features, allowing firefighters to switch between fog and smoothbore settings. This flexibility can be invaluable in dynamic fire situations.

Ultimately, the decision between a smoothbore and a fog nozzle should be guided by the tactical requirements of the situation, the experience of the crew, and the specifics of the structure and fire behavior.

Understanding the Impact of Nozzle Choice on Standpipe Operations

When it comes to standpipe operations, the selection of the right nozzle is crucial for both safety and efficiency. Each fire department, whether large or small, faces unique challenges and conditions that influence their equipment choices. What works effectively in one region might not be suitable in another. Here’s how nozzle selection can significantly impact these operations:

1. Safety Considerations

• Pressure and Control: Nozzles that require higher operating pressure can be difficult to manage, leading to potential safety risks. For instance, maintaining control over a 1.75” hose with a 100 psi fog nozzle can be challenging, especially under duress in high-pressure situations.
• Compatibility with Hose: The right nozzle ensures a stable connection and smooth operation. Mismatched equipment can lead to hose whipping or a lack of directional control, putting firefighters at risk.

2. Efficiency in Water Delivery

• Flow Rate: Different nozzles provide varying flow rates. Choosing a nozzle that optimizes flow for the specific building or fire size ensures that water is delivered effectively and promptly, minimizing damage and controlling the fire more efficiently.
• Stream Patterns: Adjustability in the nozzle’s stream pattern—from fog to straight stream—can enhance the effectiveness of water delivery, enabling firefighters to adapt to changing fire dynamics quickly.

3. Operational Flexibility

• Ease of Use: Some departments rely on older, familiar nozzles that align with their standard operating procedures, even if they aren’t the most efficient. By experimenting with modern nozzles designed for today’s challenges, fire departments can improve adaptability on the scene.
• Cultural Adaptation: Many departments develop a preference based on historical use and training. However, examining current evidence and being open to modern nozzle options can lead to adopting practices that improve overall safety and effectiveness.

Fire Engineering has some excellent articles on drops of water. The authors actually did scientific experiments. The results showed that during an interior attack, the drops from a smoothbore (SB) actually made it through the fire gases as they fell and cooled the solid burning fuels. The water drops from a fog on a straight stream were smaller than those of a SB and were consumed in the upper gas area, not making it down to the burning solid fuels to stop the production of more heat/fire gases that kill and will cause the interior to continue to burn.

Myths and Misconceptions

There are several myths about smoothbore versus fog nozzles that need addressing. One such misconception is that penetration and distance are different factors; however, they are essentially the same. The straight stream from a properly adjusted fog nozzle is only marginally less effective than a comparable solid stream from a smoothbore.

When it comes to GPM and pressure, it’s crucial to compare apples to apples. Make sure to choose the right nozzle for the job by understanding these metrics in context.

Personal Preferences and Practical Use

I LIKE BOTH. But, if I am stretching for an interior attack, I would prefer a SB backed up by a fog. If stretching for exterior work, I would prefer fog. I can tell a difference between the two when operating inside with high heat conditions. The SB causes less upper steam and gives a fast knockdown. Fog requires the windshield wipers on the mask and heat conditions do rise more so than that of a SB.

In the end, they both are excellent nozzles if they are flowing more than the BTUs being produced.

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. Bad nozzle discipline has given us fog dogs a bad name!!! BTW the FOG nozzles place is on the 1 3/4 ONLY…STOP USING IT ON BIGGER LINES AND MASTER STREAMS!

Now, let’s dive deeper into why this discipline is so critical. Fog nozzles offer versatility, allowing you to switch between direct and indirect attack strategies. This flexibility can be crucial in pushing fire and combustion products away from your advance. Yet, this adaptability comes with its own set of challenges.

Advantages of Fog Nozzles

• Steam Generation: In confined spaces, fog nozzles create steam, which can suppress fire effectively. However, this is only beneficial if the area is clear of unprepared firefighters or victims.
• Gas Entrainment: These nozzles can entrain around 5,000 cubic feet of gases per minute into the stream, aiding in controlling the fire under the right circumstances.

Disadvantages to Consider

• Positioning Hazards: Using a fog pattern when above or between the fire and the ventilation point is risky. This can lead to steam being forced back over the crew, increasing the danger.
• Heat and Condensation: The steam generated condenses upon anything cooler than 212°F, including you and your gear, bringing 970 BTUs per pound back onto the crew. This can lead to burns and other heat-related injuries if not managed properly.

In essence, while fog nozzles are powerful tools, their proper use hinges on strict discipline and understanding of their inherent risks and benefits.

 

 

Conclusion

Ultimately, the effectiveness of standpipe operations hinges on selecting the right combination of hose and nozzle. Fire departments are encouraged to assess their specific needs and consider new technologies and methodologies. By doing so, they can ensure that their choices promote not just tradition but enhanced safety and operational efficiency.
