U3 ICC Tank Tightness Testing
1. On a steel tank without cathodic protection, if a coating b. Current flow is in-
is flawed, what happens at the flaw? creased from this area
a. Cathodic surface is increased
b. Current flow is increased from this area
c. Current flow is increased to this area
2. On an impressed current cathodic protection system, b. Cathode
the negative wire of the rectifier is connected to the:
a. Anode
b. Cathode
c. Drop tube
d. Dielectric union
3. All are examples of acceptable release detection for a. Impressed current ca-
tanks, except: thodic protection
a. Impressed current cathodic protection
b. Automatic tank gauging
c. Statistical inventory reconciliation
d. Soil-vapor monitoring
4. When a tank is temporarily closed, the cathodic protec- b. Must remain in opera-
tion system: tion
a. Must be turned off
b. Must remain in operation
c. Should be removed
d. Operator can have it on or off.
5. When a steel tank is installed with a galvanic CP sys- c. To electrically isolate the
tem attached, the tank gauges are usually connected tank from the tank gauge
through a riser with a dielectric bushing. What is the
purpose of that?
a. To prevent static discharge
