"5574附录B中，内浮顶罐浮盘上方是A区。但是浮顶落地后，区的通气孔打开，油气肯定会逸散，浮盘下方油面以上肯定可以看作A区浮盘上方又不能单纯的类比拱顶罐将通气孔周围R=1.5m的范围认定为A区。因为外浮顶浮盘落地后浮盘上方的油气不像拱顶罐能够及时逸散。会不断积聚会不会达到B区的标准？简述：浮盘落地后浮盘上方有没有可能出现B区？有大佬能给解答吗？

区域划分不是以平面划分而是直接涵盖了空中么？没太明白你说的

这个划分第一次看通常都是根据55558做的都是当作A区所以也没有这个疑问

肯定不是只平面啊油气这个东西四处飘散的你看一下5574附录B就明白了

5558对浮顶罐浮盘上方也是列为A区不是B区

"7. 那个是浮顶我认为是固定式"
