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.
