A hosepack is a backpack containing fire hose in a preconfigured arrangement, sometimes completely made from fire hose without a bag, which is used to quickly facilitate the construction of a hose lay.
In the context of wildland fire fighting, hosepacks are widely used in areas where fire trucks are unable to access.
When deployed they always have laterals off the trunk line that allow water to be used at any point in the progression of the hose lay.
It is used in conjunction with standpipes in high rise buildings to quickly deploy hose on multistory buildings.
[5] Various devices, commonly referred to as fire hose vacuums or "hose vacs", are becoming more prevalent that make packing hose easier as well as facilitating the removal of air, which makes the packs smaller and easier to deploy.
