AIR and Fuse Separation

Question

Hello Guys! As in the topic, I have question about AIRs and fuse separation. In a FSAE rules we have: "The AIRs and the main fuse must be separated with an electrically insulated and fireproof material to UL94-V0 from the rest of the accumulator. Air is not considered to be a suitable insulation material in this case". We are wondering in team about interpretation of this - AIRs and main fuse must be in other segment of accumulator container and NO OTHERS elements cant be with them? This is good interpretation? In our container, precharge resistor is part of main current patch, connected paralell to AIRs, so it also must be separated, or it can be with AIRs and fuse? Moreover, In ESF we have: "Describe how the fuse and AIRs are separated from the cells" - (battery cells?) - maybe AIRs and main fuse must be only seprated from battery cells? We already have separated battery cells with AIRs and fuse, but they are in the same section with PCBs.
