Tank Cleaning Verification

Tank Cleaning Verification

Tank Cleaning Verification

(OP)
The government wants an independant method to prove several tanks (200 mblls each of JP-8) are clean before they are turned over to another agency.  API 1404 recommends using a handheld LEL meter to determine vapor content, but this is not objective or quantitative.  The government is interested in taking air samples to be analysed by an independant lab.  My two questions are...

1.  Is there a regulation or industry standard that correlates quantitative air sampling to tank cleanliness?

2.  Is there an alternative sampling practise or approach that can be used to independently verify a tank is clean? (other than visual inspection by the government)

RE: Tank Cleaning Verification

Marine chemists are used to certify tank to be clean and gas free.
