Sprinkler systems are commonly used in wildland firefighting for structural protection and fireline re-enforcement with the objective of wetting fuels in the path of an on-coming fire. The sprinklers used in wildland firefighting are generally those which can be purchased at the local hardware store; and sprinklers are typically mounted on the ground or they are elevated using simple mounting methods e.g. pole or direct attachment.
Although current sprinkler design meet many deployment scenario objectives, in some instances the wetting of fuels is sometimes restricted by the design of the sprinkler e.g. angle height to reach further into tree canopy along a fireline. During a prescribed burn firefighters were observed altering sprinkler orientation using a homemade apparatus (see Figure 1). Their objective was to adjust sprinkler arc and propel water higher into the tree canopy to increase the wetting action along the fire guard.
This study is geared towards sprinkler design improvements to allow for increased vertical spray, which is thought to allow for more overall deployment flexibility in both wildland firefighting and prescribed fire.
