In discussing segregation, the IMDG Code defines what it means by the term "separated from". Which of the following is that definition?

Either in a vertical or horizontal separation: if the intervening decks are not resistant to fire and liquid, then only in a longitudinal separation is acceptable. For "on deck" stowage, this means a distance of at least 12 metres. This distance also applies to one package stowed "on deck" and another in an upper compartment.

With an intervening compartment, being both a vertical and horizontal separation. Provided an intervening deck is resistant to liquid and fire, a vertical separation of 6 metres is acceptable. For "on deck" stowage, this segregation means a distance of at least 12 metres irrespective of compartment divisions.

Effectively segregated so that the incompatible goods cannot interact dangerously in the event of an accident, but may be transported in the same compartment or hold or on deck, provided a horizontal separation, projected vertically, of 3 metres is obtained.

In different compartments or holds when stowed "under deck". Provided an intervening deck is resistent to fire and liquid, a vertical separation may be accepted as equivalent. For "on deck" stowage, this segregation means a distance of at least 6 metres.

During maintenance of a piston rod stuffing box on a large, slow speed diesel engine it is usual to measure the butt gaps between the sealing ring and scraper ring segments. What would be the effect of these gaps being too small?

If the gaps are too small they could close due to the radial wear of the rings before the next scheduled overhaul preventing the rings from contacting the piston rod and sealing it.

If the gaps were too small then no oil could pass up the piston rod to lubricate the sealing rings.

If the gaps are too small the rings could score the piston rod.

If the gaps are too small then the flow of scavenge air through the gland would be reduced and the gland would overheat.

The temperature control for the central cooling system low temperature circuit has failed and a new 3 term controller is to be fitted. Which of the given options would be the correct method of setting up the controller?
