The only use of "Hosing Down that I have seen is the sorting tables in produce warehouses. The sorting tables have coaster on them, so they can roll then outside to a large parking lot drain and hose them down once a week. This is a requirement of the City of Los Angeles Helth Department. The sorting tables are used to remove and repackage produce before it goes to the stores.
A side note:
Originally, the forklift chargers and sorting tables were wired with 480 power cords. The city electrical inspector required us to upgrade to fused and lockable disconnects. He didn't like the idea of manually disconnecting 480 three phase.
