Mattydale Lay (firefighting)
Encyclopedia
A Hose Lay or hose load is a preconfigured arrangement of fire hose that facilitates deployment under high stress, high danger situations.
A Mattydale lay, also called "cross-lay", "speedlay", and "transverse lay", is a method of storing hose on a fire engine. This method of storing hose is designed for rapid deployment of a hose line to attack a fire. In this manner, the hose is stored perpendicularly across the fire apparatus, usually above or adjacent to the pump panel, instead of the usual parallel storage in the rear. This allows the firefighter to pull the hose in the direction of the fire instead of having to make a turn.

, it is laid in a compartment or hose bed in a predetermined manner depending on the type of lay being built. Almost always the nozzle or female end or both are made easily accessible from the exterior. In the case of a “pre-connect” the female coupling is attached to a discharge on the engine, making deployment even faster..

Use
Most modern American fire apparatus use some sort of variation of the Mattydale lay. There are several different types of "hose loads" in use, which is the way the hose is folded in the Lay:- Accordion load - The hose is loaded so that when it is flat, it is standing on end. The finished load resembles an accordion.
- Flat load - The flat hose is simply placed in the track, so that it is stacked. Most large supply lines coming off of the back of the fire apparatus are stored using a flat load because of ease of deployment and re-packing.
- Horseshoe load - Similar to the accordion load, but the whole load is folded in half, resembling a horseshoe. Some departments use a "reverse horseshoe" load.
- Minuteman load - A special load that allows the firefighter to pull a large section of the hose onto their shoulder and have it drop off (called "paying out") in an organized fashion as they advance towards the fire.
- "S" load, more commonly known as the "triple layer" load - The hose is folded three times before being loaded. The threefold resembles a large letter "S". This method allows all of the hose to be deployed rapidly in an organized manner, and is particularly useful for operating in tight spaces.
Constructing a Hose load
Generally it takes several individuals to build a hose load, at least one on each end. A third person handing the hose to the two individuals on the ends facilitates the process. After the desired length of hose is connected, and sometimes the air removed from the interior with a fire hose vacuumFire Hose Vacuum
A Fire Hose Vacuumis a small pneumatic device that removes residue air from the inside of a fire hose, thereby making it smaller and somewhat rigid, thus allowing more hose or other equipment to be stored on a fire apparatus as well as making loads or packs deploy with increased ease....
