What is fog stream?
What is fog stream?
– A fog stream is a patterned stream composed of fine water. droplets. – Greater heat absorption due to more surface area of water. – May be used in close proximity to energized electrical. equipment.
What is an advantage of a fog nozzle?
Fog nozzles play an important part in firefighting tactics due to their versatility. The wide variety of fog nozzle manufacturers allows them to accommodate different sizes of fire hose—most often attack hand line—and streams and are capable in both fire protection and attack.
What is a characteristic of fog streams?
Which is a characteristic of fog streams? d. Shorter reach than solid streams.
What are smooth bore nozzles used for?
Smooth Bore Fire Nozzles Smooth bore nozzles also use the lowest engine pump pressures, allowing for maximum reach. Smooth bore nozzles are often referred to as solid bore nozzles because they produce a solid stream to provide maximum reach and penetration to the seat of the fire.
What is an advantage of a straight stream over a fog stream?
What is an advantage of a straight stream over a fog stream? Longer reach. crews are working inside the building.
What are three types of fire streams?
What are the 3 different hose streams?
- Solid stream.
- Fog stream.
- Broken stream.
What nozzles does FDNY use?
Response: The predominate nozzle used by FDNY engine companies is a smooth- bore controlling nozzle with stacked outer stream tips ranging in size from 1 1/8- If you are a current subscriber, login here to access this content.
Why do you use a fog stream in suppressing a room where the fire started?
Applying water to an interior, compartmentalized fire via a fog nozzle, when done correctly, breaks up water droplets into even smaller units. This allows for a more rapid conversion of water to steam, which absorbs more heat from the air, walls, ceiling and floor of the room.
How many GPM is a handline stream?
About the HANDLINE Series The wide flow range of 95-300 gpm (360-1150 l/min)includes operational pressure choices of 100 psi (7 bar), 75 psi (5 bar) and 55 psi (4 bar).
Which type of stream produces greater heat absorption?
A solid stream has greater surface area to absorb heat.
What is the difference between a straight stream and a solid stream?
The solid stream is exactly as the term describes, solid. Due to the unobstructed path through the smooth bore nozzle, the stream produced is a solid tube of water. The straight stream is similar in appearance to the solid stream but rather than being a solid stream of water it is a hollow stream of water.
What is the difference between a solid stream and a fog stream?
The difference between the solid stream and the straight stream goes beyond the solid vs. hollow stream. The water droplets produced by the straight stream of the fog nozzle are smaller than those produced by the solid stream of the smooth bore nozzle.
