Questions with Answers.
Is this statement true or false? Fiberglass and flexible plastic piping do not need to have
cathodic protection. - Answer False.
Cathodic protection - Answer a technique used to control the corrosion of a metal surface by
making it the cathode of an electrochemical cell. A simple method of protection connects the
metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.
Fill in the blank to make the statement correct. Owners and Operators must keep the most
recent ___ records of cathodic protection testing. - Answer 2

the specified diameters can temporarily use manual tank gauging when it is combined with tank
tightness testing. - Answer True
True or False?
Under UST regulation combining manual tank testing and tank tightness testing can only be
used for 10 years after the tank was installed and may not be used for any tanks installed after
April 11 2016. - Answer True
