Use of life raft inspection book:

This inspector book is intended to be used as a job aid by Coast Guard marine inspectors during inspections of life rafts at serving facilities. The lists contained within this book are not intended to limit the inspection. Each marine inspector should determine the depth of the inspection necessary. A check box should be a running record of what has been inspected. It does not imply that the entire system has been inspected or that all or any items are in full compliance. This job aid does not constitute part of the official inspection record.

This document does not establish or change Federal laws or regulations. References given are only general guides. Refer to IMO publications, CFRs, NVICs or any local produced site guides for specific regulatory references. Not all items in this book are applicable to all life rafts.

Reference 46 CFR 160.151-57

Annual Inspection

Working pressure leak test

Must be conducted in accordance with IMO Resolution A.689(17), paragraph 2/5.1.5

Inflation hoses

Pressurized and checked for damage and leakage
Maybe included as the Working pressure leakage test

Inflatable floor

Inflated until firm and let stand for one hour
Must still be firm after one hour
Seams connecting floor to buoyancy tube free from slippage, rupture, and lifting of edges

Survival equipment

Replace if passed expiration date
Repaired or replaced if damaged and unserviceable


Replaced with a fresh battery if passed expiration date
Measured voltage is less than rated voltage

Top and inside canopy light

Inspected and tested as prescribed in the servicing manual unless battery is included above
Each cell that is outdated, fails test, or is not tested must be replaced

EPIRB and/or SART (If equipped)

Tested and inspected in accordance with the manufacturer's instruction EEPROM must be tested using the integrated test circuit and output indicator to determine whether its operative each EProbe or sort not operative must be prepared and replaced

Manual inflation pump

Tested for proper operation

Identification labels

Damaged faded or incorrect instruction or identification labels on life raft or containers must be replaced

Retro reflective material

Each life raft examined to ensure that it is properly marked with retro reflective material Arrangement of retro reflective material must meet the requirements of IMO Res. A.658(16) Damaged or missing retro reflective material must be replaced with Type 1 material approved under Part 164 subpart 164.018, of this subchapter as complying with SOLAS

Inflation cylinder

Each inflation cylinder must be weighed
If weight loss exceeds 5% of the way of the charge, it must be recharged

Recharged inflation cylinders

Must renew:
The poppet pin, if any
Each plastic or elastomeric seal and other parts that deteriorate with age

Each recharged cylinder must stand for at least 2 weeks and be checked for leakage by weighing before being reinstalled
As an alternative: For fast detection. If provided for in the approved servicing manual, mechanical or chemical test

Hydrostatic test inflation cylinders (if required)

Tested in marked in accordance with 49 CFR 173.34

Davit launched life raft

Lunching load test conducted at every second servicing
Test must be conducted in accordance with IMO Res A.689(17) par. 2 /5.2

5 years gas inflation test

At every 5th in your servicing, each life raft must be removed from its container and inflated by its gas inflation system will still folded.
Any minor leaks during gas inflation must be repaired
Life rafts 10 or more years past its date of manufacture must be condemned if it leaks extensively, or shows fabric damage other than minor porosity during the gas inflation test

Life Raft (10 year or greater)

Life raft (10 year >)

If a gas inflated test is not conducted, a "Necessary Additional Pressure" (NAP) test must be conducted
A NAP test must be completed before the annual test inspection

Procedure for NAP test (Life raft 10 years >)

Plug or otherwise disable pressure-relief valve
Gradually raise the pressure to the lesser of 2 times the design working pressure
OR as specified in the servicing manual
After 5 minutes there should be no seam slippage, cracking, other defects or pressure drop greater than 5%. If crackling is audible or evident, accompanied with the pressure loss condemn the life raft.

Floor seam test procedure (life raft 10 years >)

Buoyancy tube supported a sufficient distance above the floor of the servicing facility, a person weighing not less than 165 pounds shall walk or crawl around the entire perimeter of the floor of the life raft
The seams connecting the floor to the buoyancy tube must be inspected for slippage, rupture, and lifting of the edges
According to the servicing manual
