(4) Laying out hoseline.
Do not position hoseline in an area where leakage can contaminate drinking water.
Failure to observe this warning can result in serious injury or death by poisoning.
C A U T I ON
Do not allow heavy trucks or any tracked vehicles to drive over hoseline.
Do not lay hoseline through marshes, swamps, watercourses, or areas subject
to periodic flooding.
Failure to observe these cautions can result in equipment damage or failure.
(a) Manually position the hose until the first 50 feet(15m) of hose is in place. After 50 feet of hose is in
place, the weight of the hose will hold the line in position.
(b) The assistant driver must observe the hose-laying operation and tell the driver to speed up, slow
down, or stop the truck depending on the needs of the line walkers straightening and repositioning the hoseline. He must
also observe for catching or binding of the hose as it flakes out of the flaking box. The recommended hose laying speed
is approximately 10 mph (16 km). The optimum speed for any installation will vary depending upon the terrain, manpower
available, and how far the hose must be manually moved.
(c) As the hoseline is laid out, two persons (line walkers) should walk the line behind the truck to perform
the following tasks:
C A U T I O N
HandIe hoseline with care. Rough handling or abuse can cause hoseline damage
1 Straighten out kinks or bends in hoseline.
2 If hoseline is being laid along an existing roadway, hose must be manually repositioned to a secure
point 5 to 10 feet (1.5-3.0m) from road.
3 Remove small obstructions, branches, and sharp rocks which can damage hoseline.
4 If required by conditions of use, follow security guidelines given in paragraph 2-6b, Step (5).
(d) Retain empty flaking boxes for repacking.
