A 3 minute video, with one quick check at 2:14 that does not count towards your score.

Pre-test Watch to the end to continue

Kia ora Aroha. You stopped on the gap rule last night. In your own words, how far apart do a Class 3 drum and a Class 5.1 oxidiser need to be on the same deck?

3 metres from the cab end I think

You have the distance right. It is measured between the goods themselves though, not from the cab. Want to see that bit again? It is 25 seconds.

New note, pinned to 1:10

Video 1:12, scene 6Gap is 3 m of clear deck between the two pallets, measured flat. Not from the cab.

Video 0:41, scene 4Check the subsidiary risk too. Strictest rule wins.

0:34The primary risk is the main hazard. Subsidiary risks are any extra hazards on top of that.

0:46If they give you different requirements, always follow the most restrictive one.

0:55There are four ways to segregate. Separate vehicles. Separate freight containers. An approved segregation device, where it is allowed.

1:04And the fourth is the gap rule. On the same vehicle, keep incompatible goods at least three metres apart, measured horizontally.

1:16That is three metres of clear deck between the two lots of goods. Not from the cab, and not over the top of the load.

1:30If your deck is too short for the gap, use one of the other three ways instead.
