Tips for multi insurance inspection? What are they looking for?

[Johann Jells]

I think this is the 1st time an insurance inspector has visited my multifamily in the 23 years I've owned it. I live here and use the basement as storage and workshop, and that my biggest concern. I figure I need to hide any 'accelerants' like oils and solvents, and hide my welding gear.  What about general flammables like a wall of catalogs, or a stack of lumber? I have a lot of major tools like lathe, bandsaw, table saw etc. Is that a red flag?

I think my alarms are in order, the state inspects every 5 years.  I'm not required to have extinguishers in the common areas, but I have them anyway, one on every floor and 2 in the basement.  Occasional I've gotten some moron who says that even though I'm not required to have them, if I do provide them I must pay to have them inspected!

Any tips from your experiences would be appreciated. Thanks.
