The “V”
When positioning the aerial for potential rescues, most aerial operators understand you position in a fashion that gives you the most scrub area. One thing operators may not consider is the position of the tip at any potential location in that scrub area. The “V” is what we describe as the space between the tip and the objective. When your objective is inline with your turntable, there is little to no “V.” However, as you begin to deviate from this inline position, you will begin to create a gap between the tip of the aerial and your objective. This is detrimental in the event of an aerial rescue. Consider how difficult it may be for you to exit through a window over the aerials beam, then imagine bringing an unconscious body across it.
Decreasing the “V” is the goal when you know your objective, but this will only likely come to play when you have people preparing to jump or if the area of the fire is obvious and fairly confined. Couple that with the competition for space for your apparatus on the fire ground and you will very possibly not find yourself with the perfect position when seconds count. As an aerial operator, understand the “V” and position your apparatus accordingly.
Below, you will see some demonstrations of the “V.” In the first picture you’ll see perfect postion where the beams are inline with the objective and you can get on and off the ladder directly from the rungs. In the subsequent pictures you will see how the degree of the “V” expands and you will have a harder time using the rungs. As an aerial operator, you should recognize as this “V” expands and begin to lower your aerial below the sill to get the beams flush with the sill. This will keep you from having to cross the “V” with a victim which will be difficult to impossible!
Side note, on studying this concept with our crews, we really learned how crucial the specs of you aerial’s lights are. We lose over a foot of space with our lights as we open the “V.” This will be detrimental in our department if we have to make a grab over the beam. .
