Ambiguous set of classifications for common MEP items

In 2019 (and still now :) ) i did a lot of work going through models object by object checking their IFC classification. I found many objects I was unsure where they would belong. I made a list here of the objects I would find in a lot of models. Due to their commonplaceness, I would assume IFC should cover them. For example fire extinguisher.

List [here](https://forums.buildingsmart.org/t/how-to-categorise-electric-strikes-idf-panels-egress-paths-and-more/2018)

Edit: I've just tabulated them here.

Can we go through this list and figure out where they belong and whether or not any enums can / should be added?

Ping @CyrilWaechter as many of these are MEP things.
