TABLE II – SEGREGATION DISTANCE
| SEGREGATION TYPE | LONGITUDINAL | TRANSVERSAL | VERTICAL |
|---|---|---|---|
| Type 1 | No restrictions | No restrictions | One stacking allowed |
| Type 2 | One container space or neutral container | One container space or neutral container | Stacking prohibited |
| Type 3 | One container space or neutral container | Two container spaces or two neutral containers | Stacking prohibited |
| Type 4 | A distance of at least 24 meters | A distance of at least 24 meters | Stacking prohibited |

NOTES:
1) The tables are based on the segregation chart of the International Maritime Dangerous Goods Code (IMDG/CODE-IMO).
2) A “container space” means a distance of at least 6 meters (six meters) in the longitudinal direction and at least 2.4 meters (two meters and forty centimeters) in the transversal direction of storage.
3) A neutral container means a container with cargo compatible with that of the dangerous goods (for example: container with general cargo – not food).
