Study Notes

SCBA Bottle Setup and Hose Handling

First fold of hose should be positioned against the SCBA bottle with the female coupling about 10 inches below the shut-off valve.
Alternate folds should form a loose "U" shape against the bottle, ensuring they remain even.
Upon reaching the male coupling, attach the nozzle and shut off. Invert the last fold to protect the nozzle behind the final fold of the pack.
Secure the first nylon strap around the radius of the "U," utilizing straps at least 24 inches long with the buckle in a safe location.
Place the second and third nylon straps around the hose opposite each other, positioned at the middle of the SCBA bottle, and secure buckles safely.
The fourth and fifth nylon straps should be placed approximately 8 inches from the end of the hose packs, ensuring one strap goes through the nozzle bale.

Safe Use of Hose Lines

Nozzles must be shut off after attachment or whenever the flow ceases for safety.
Charge hose lines from heights only after securing them in position.
Clear and secure hoses leading to upper floors from ladders to ensure safe operation.
Water should be drained at street level before lowering hoses from elevated positions.
Avoid directing water streams at individuals or premises unnecessarily.
Ensure care during hose stream use from ladders, limiting horizontal movement to 15 degrees from an "in-line" position.

Backing Up the Nozzle

Backing up the nozzle relieves strain caused by the reactionary force of water streams.
Maintain staggered positions among members holding the hose, keeping hose lines clear of sharp bends.
Notify the member at the nozzle before leaving the hose line, and ensure that no one is left alone on the nozzle.
If a hose needs repairs, mark the damaged area with black tape and roll the hose with the female coupling forming the core.
Use an F-175 tag describing the issue for easier identification and repair.

Hose Testing Procedures

Station Commanders must ensure all rubber-lined hoses are tested annually, especially new and repaired hoses.
Testing should occur immediately after receipt or repairs.
Maximum interval between tests is 12 months.
One-inch double jacketed hoses are tested at 400 psi, while other rubber-lined hoses are tested at 300 psi.
For testing, lay out hoses from the pump without kinks, up to a maximum length of 300 feet, and attach a shut-off butt to minimize hazards.
Bleed off air by opening the shut-off, elevating above discharge level, and filling the hose with water, controlling flow carefully.
