When UN 2211 and UN 3314 are loading on board vessels IMDG Code stowage instruction states

Shaded from radiant  heat and protected from sparks and open flame. When stowed under-deck, mechanical ventilation shall be in accordance with SOLAS regulation II-2/19 (II-2/54) for flammable liquids with flashpoint below 23°C (c.c).

These UN numbers are assigned with stowage category E, which means ON DECK or UNDER DECK on Cargo ships or passenger ships carrying a number of passengers limited to not more than 25 or to 1 passenger per 3 m of overall length, whichever is the greater number and prohibited on passenger ships in which the limiting number of passengers transported is exceeded

Though both UN 2211 and UN 3314 are assigned to class 9 for segregation purpose one must consider this as class 3 but separated from class 1 except 1.4S
