A noxious liquid which will crystallise and eventually bond into solid form at ambient, or less than ambient temperatures unless an external heat source is applied.

A noxious liquid substance which, in the case of a substance with a melting point of less than 15°C which is at a temperature of less than 5°C above its melting point at the time of unloading, or in the case of a substance with a melting point equal to or greater than 15°C which is at a temperature of less than 10°C above its melting point at the time of unloading.

You have loaded a cargo of n-Propyl Acetate to all tanks. They are each loaded to around 98% capacity. You now have to clear the lines into the ship. What is the principal risk in this operation?

Unless lines are cleared working from aft towards forward, they will simply fill up again as other lines are cleared.

Unless the shore personnel are cooperative, they may cease blowing before you have had a chance to clear each one of the ship's lines.

Unless carefully controlled, cargo will gravitate from one tank to another.
