LRU-16/P Flashcards
How is the canopy on the one man raft closed?
Hook and pile.
How is the oral inflation assembly for the inflation tube identified?
Its either solid red or has red tape around it.
Where is the sea anchor?
At the bow.
What is the purpose of the sea anchor?
Prevent oscillation, stabilize, and slow drift.
What are the five tasks involved when preforming life raft inspections?
Screening inspection, functional test, leak test, inflation assembly inspection, and records updating.
What should you do prior to actually beginning any inspection of a life raft?
Check TO and forms to know what inspection is needed.
Which cleaning material is preferred for the LRU-16/P?
Knight spray nine.
When may an overcharged cylinder be used for a functional test?
Never.
How often is the functional test performed?
Every 4th inspection cycle.
How often should a leakage test and all other inspection tasks be performed?
On issue and every inspection cycle there after.
What is the ideal climate for storage of the LRU-16/P?
75 degrees, 60%.
To what pressure is the LRU-16/P inflated to for a leak test?
2.5 PSI
What is the max time allowed to inflate the LRU-16/P using an OSHA approved air nozzle with 40 PSI?
2min30sec
Describe how to inflate the floor ans spray shield.
Compressed air not the exceed 5 PSI. Inflate the floor to .5 PSI and the shield until it dimples.
What is the min and max time the LRU-16/P can sit during a leak test?
Min:6 Max:8 hours
Describe the areas of the raft you dust with talc.
The raft between the seams and cracks. (crotch)
What special item must you use to deflate the spray shield on the LRU-16/P life raft?
Adjustable vacuum adapter.
How do you remove all air from the compartments of the LRU-16/P?
Roll the raft.
How do you annotate the inspection date and activity on the CO2 cylinder?
2X3 in piece of fiberglass tape.
Where do you stencil the date, activity, and type of inspection on the raft?
Underneath starting at bow.
What size hanks are used for the sea anchor line?
Appx. 8in.

What is the purpose of the adapter clip?
Prevent inadvertent release of the swag ball.
WHat is the purpose of the ballast bags?
Stabilize boarding
How is the floor inflated?
Orally.
What is the torque value for the CO2 cylinder?
50-60in lbs

30sec.
What size blocks are used and how are they positioned for a buoyancy tube twist check?
3.5in diagonally.
When inflating the spray shield what is the max pressure?
5PSI
What is the min and max time it can stay inflated during a leak test?
