To avoid creating a jam of tangled hose in the hose chute:
•
Lay couplings so they are pulled out straight, without flipping around.
• Lay hose so that it never crosses over itself when paying out.
• Maintain vehicle speed of 5 MPH or less. At 5 MPH, seven feet of hose is pulled out each second. If you travel
more than 5 MPH, you are likely to cause a hose jam in the hose chute.
3-2.4 Hose Beds
Hose beds come in many shapes and sizes. Hose characteristics vary with the size, type, and age of the hose.
Experiment with different methods of packing a specific hose, bed, and chute combination to determine a packing
method that will lay out without snagging or snarling. Make sure you learn the maximum MPH at which hose can be
laid out.
3-2.5 Hose Deployment
If hose is to be laid from a moving apparatus, first test the packing method under controlled conditions to learn the
MPH at which hose will lay out smoothly, without snags or snarls.
Any operation where people are working around a moving vehicle is dangerous. All occupants must be seated and
belted while the vehicle is in motion. NEVER ride on rear steps or other areas outside the cab.
Pack hose carefully in any hose bed to minimize the risk of hose snags or snarls as it lays out.
Hose that snags or snarls during layout from a moving vehicle can fly about, causing serious injury or
death to bystanders.
NEVER ride on rear steps or other areas outside the cab.
Limit speed to 5 MPH when laying hose.
ALWAYS use a spotter when backing up.
Keep the spotter and all other people clear of the vehicle's path.
All occupants MUST be seated and belted while vehicle is in motion.
