Question 1 of 5

In non-inerted cargo tanks, the metallic ullage bob or the sampler should not be introduced into the tank for a period of at least ... after the cargo loading has been stopped.

Question 2 of 5

How long should you wait with introducing an unbonded metallic ullage bob or the sampler without a full length sounding pipe after the tank cleaning operation?

Question 3 of 5

Is this statement true or false? After stopping the loading, the sounding bob should not be lowered for 30 minutes, in a tank fitted with a full-depth sounding pipe.

Question 4 of 5

Is the following statement true or false? Accumulated static charge inside the tank is not allowed to recombine or flow to the earth since it may lead to a static discharge of an electrostatic charge and can cause an explosion.

Question 5 of 5

Is the following statement true or false? The separated charge inside the tank due to cargo turbulence tends to deposit on the sharp ends such as tank cleaning machine nozzles, high-level alarm probes.
