To reduce the chances for drift: • Use the lowest practical pressures. • Leave an untreated edge. • Angle nozzles toward the ground, slightly forward in the direction of travel. • Use nozzles with the largest practical openings. • Use low-volatile formulations of . Those rust scales will very likely clog a fog nozzle. This does not even consider the other likely debris that is inside the standpipe that even a 10 second pre flush of the standpipe connection may fail to clear. Fog nozzles are just like any other tool we use; For certain applications it is absolutely the best choice.
But, fog nozzles need psi at the tip, sometimes it’s hard enough getting 80psi up there.” Oh I’m going to need to do some work here, or just drop the whole thing all together. Yeah right, I can’t let this go unchallenged. So I ask them for the fog nozzle that they had removed. They had it nearby. Good for them. (/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.

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.
Yet, despite Dr. Oyston’s invention inwidespread use of fog nozzles for fighting fires in the United States and the rest of the world remained virtually non-existent. Fog Nozzles, World. Decide whether a solid bore nozzle or fog/straight stream nozzle is required.
Quality fog nozzles produce almost as good a straight stream as a solid bore nozzle but do require a higher inlet pressure. The reach of a quality fog nozzle at psi is about the same as that of a solid bore nozzle or a multi-purpose nozzle at 50psi.

A fog nozzle will usually have a higher nozzle and pump pressure with lesser GPM. This is all depending on the type of fog nozzle (low pressure or high pressure) and the type of hose and so forth. There have been tests done that have all the numbers.
I believe Fire Engineering magazine recently did a study on smooth bore vs. fog. Back to my. Hi r/Firefighting. 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 of 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).
Download The Safe and Effective Use of Fog Nozzles: Research and Practice Free Books. Safe and Effective Use of Fog Nozzles: Research and Practice (Wiseman & Bertrand, ) includes adaptation of the formula to the use of SI units. Based on the results of their research on extinguishing compartment fires, Royer and Nelson developed the following formula to determine the volume of water (in gallons) required to control a fire in.
Where only superheated smoke is encountered along this path the use of a straight stream will have little effect but the use of 'pulsed' fog WILL have great effect on preventing flashover/backdraft. Understanding how and why nozzles work better prepares firefighters to make quick, effective knock downs.
The nozzle on the end of a fire hose is one of the most important pieces of equipment that. 2) Fog streams produce the most water surface for heat absorption, but also have the shortest range. Fog nozzles are designed to work most effectively at PSI. Fog nozzles are used on hand held lines as well as on master stream appliance.
While being used either way, the nozzle pressure would be the same, Size: 1MB. RESTRICTION: For aerial application use only nozzles producing coarse-ultra coarse droplets. Do not use nozzles producing fine-medium size droplets. For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length may further reduce drift without reducing swath width.

(T/F) A portable electrical tool is considered safe to use if it has an external grounding wire taped to the connection cord that is connected at one end to the tool casing and the other end to the grounding pin of a three-prong plug.Fire attack: Advancing hose lines.
Staff needed to perform the safe and efficient deployment of the hose selected. Use solid stream nozzles or set fog nozzles on straight stream setting.Use spray nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift.
Maintain a spray pressure of at least psi at the nozzles and provide proper agitation within the tank to keep the product dispersed. Lower pressures may be used with extended range or drift reduction nozzles.
