Q
Hose couplings
uses
A
- Connect sections to form continuous hoselines
- Connect hose to nozzles, hydrants, pumper connections and FDCs

fire hose Design and construction
4
Q
Nonthreaded couplings
Advantages
A
- Hoses can be connected quickly
- No risk of cross threading
- Double male or double female adapters are not needed
- Hoses can be deployed from hose bed regardless of hose load type
5
Q
Nonthreaded couplings
Disadvantages
A
- Hoses can become uncoupled suddenly and violently if complete connection is not made
- Hydrants require an adapter to make connections
- Dirt and debris can become lodged inside coupling grooves
6
Q
Inspecting hose
when and how
A

- Inspect after each use
- Ensure hose is free of soil or damage
- Check couplings for ease of operation, deformations or damage
- Identify and mark damage immediately
