Three most common loads?
1. Accordion

2. Horseshoe

3. Flat
What is a Dutchman?
A short fold or reverse bend in the hose during the loading process so that couplings are not too close to the front or rear of the hose bed and will not flip out over when pulled out of the bed.

2. Those for reverse lays (reverse horseshoe, skid load finish)
What are Finishes for forward lays designed for?
To facilitate making a hydrant connection.
What are Finishes for Reverse lays designed for?
To provide an adequate amount of hose at the scene for initial attack.
What does a Straight Finish consist of?
The last two lengths of hose flaked loosely back and forth across the top of the hose load.
How is the Reverse Horseshoe Finish made?
It is made of one or two 100-Ft lengths of hose, in the shape of the horseshoe except reversed to be easliy thrown over a shoulder and carried.
What does the Skid Load Finnish consist of?
It consists of folding the last three lengths of 2.5 inch hose into a compact bundle on top of the rest of the hose load. 3 or more pull loops hang down below the bed.
