10.1 Setback Distances
Setback distance, is the term used to describe how far back from the structure’s ingress point to setup the
ventilator. As any front line responder will tell you, techniques are based on the situation at the scene and
should not be dictated by a manufacturer's design limitations.

WF390 Owner’s Manual | REV B/0 | Euramco Group
Here's a bit of insider information: with certain designs, the fan can produce some amazing airflow
numbers set pretty far back, which is great for marketing big numbers, but when positioned at more
realistic distances (closer in to the entry point) the performance of most ventilators is pretty much the
same, because most countries use standard door sizes in the construction of buildings. All our equipment
is rated at several different door sizes to guide your proper selection and to provide a better understanding
of the ventilators capabilities.
Every structure is different, every fire is dynamic, and every piece of rescue equipment must be ready for
anything. Therefore, the topic of "setback distance" needs to be addressed. The setback distance is simply
a general range of acceptable setback distances, that will provide the desired result of ventilating the
structure.
Sometimes structural entries have large approaches, where the ventilator can be setback farther, at
distances of 4 meters or more.
Sometimes a short approach, with stairs or a turn or in a hallway, confines the useable setback distance to
3 meters or less.
The point is, you don't always know, and in this line of work you have to be prepared for anything.
When selecting any equipment for your brigade, you should already know the typical structure types and
sizes in your response area. A ventilators size and performance should be chosen based upon the
following criteria:
1. What is the average size structure in your response area?
If mixed, for example, between small residential/commercial and a few larger industrial buildings,
several smaller fans may be a more realistic choice than a single giant fan that will take up
valuable space and is difficult to maneuver. Several smaller fans, used together, can produce
very impressive air movements and easily fit within the compact compartments of most modern
fire apparatus.
2. How big are your truck's compartments?
Saving space, and minimizing weight, are increasingly becoming concerns of brigades when
deciding which equipment to choose. Furthermore, budget cuts may force fire brigades to use
their current apparatus, more efficiently. That means, packing as much equipment as possible
into your existing truck. To do this, equipment must be lightweight and as compact as possible,
while still providing the performance needed to get the job done.
3. What do you expect from your ventilator?
While there are certain factors that can affect the airflow performance of a ventilator, considering
the challenging realities faced by first responders, there really are more important things to
consider when selecting equipment than which one has the highest airflow performance in a
controlled test environment.
- Reliability:Which ventilator will keep on working after running the gauntlet on fire scene
operations for the next 3 years or more?
- Durability: Which ventilator is tough enough to start right up after the new rookie drops it
out of the rear compartment?
- Performance: Which ventilator will provide superior performance at every ventilation-
required scene in your response area?
10.2 Shared Operation Zone

10
WF390 Owner’s Manual | REV B/0 | Euramco Group
Every fire and rescue scene has an area in which all responders, their equipment, and their vehicles must
share. How this area is shared and how efficiently it is used and managed will determine the quality of the
response itself. We call this the Shared Operation Zone (SOZ).
When selecting the tools, equipment, and vehicles needed to respond to any situation, the best Fire
Fighting leaders will choose the equipment that allows them to manage their response operations the most
efficiently and effectively as possible.
Euramco Group knows this, and designs special characteristics into each product to ensure the SOZ at
your next response can be used effectively.
Any structure fire has limited ingress/egress
opportunities, as determined by the location of
the fire within the structure, the building design,
and the overall mission.
Often, personnel, along with vehicles,
equipment and hoses must be strategically
located around a single ingress point of the
structure. This obviously places restrictions on
the specifications of everything from the
vehicles, equipment & hoses to personnel and
strategy.
Vehicle placement happens first, as first
responders arrive. This immediately places
further restrictions on potential placement of
equipment. Is your equipment designed to
accommodate these restrictions? Or will you be
wishing your procurement officer paid attention
to what really matters when purchasing
equipment, now that you are facing a life &
death situation?
In an average high-rise response situation, the
SOZ gives the responders less than 500 square
meters of area to place equipment and
personnel in front of the main ingress/ egress
point. Many factors come into play.
•How to lay your hand lines?
•Where to place your main pumper,
command vehicle, and rescue truck?
•Where to stage spare SCBAs?
•Where to place your ventilator to
eliminate smoke in the ingress/egress
route? The stairwell?
Consider this carefully, through smart
equipment selection and proper fire fighter
training, develop equipment specifications and
SOPs that meet the actual challenges that you face every day, and the challenges that you will face
tomorrow. Seek the opinions and guidance of those more experienced than yourself. Make sure you are
ready!
