You are exaggerating. Yes, space is a dangerous place to live, but once you make all safety preparation and duplicate systems - it isn't that bad. And as your station get bigger - it became even easier, as more and more decks now surrounded with other decks, not cruel vacuum with space rays. And the more independent sections you have - the more potential backup sources and shelters you have in case of emergency. Potentially even safer than on planet, because stations do not suffer some logistic problems, planets do.
Hazard level should be higher than on planet because of other reason - constant maintenance. If you build a power plant on surface - you does not need to check foundation often, as giant piece of concrete will be fine for centuries. But if you build the same plant on space station, any "foundation" it could potentially have will not take that long, mostly because station could not be fully stable and any bulkhead will suffer continuous dynamical stress, that will lead to spontaneous (sometimes catastrophic) breakdowns. Yes, it could be (and should be) prevented with early diagnosis and repairs, and it is not even a hard thing, problem is - it is constant check&repair process you are unable to stop and have to waste resources for that.
And that is not all. Off course, some industries benefits from zero gravity, as some physical/chemical process are much easier in space. But most of the industrial activities (and a living infrastructure) requires constant directional force field (gravity) to function normally. Imagine milling-machine with no gravity... That is a hell with zero visibility and constant clogged airfilters. Dust, steam, any liquids or opened fire is a disaster with no gravity. So you need to make it, and it's even not that hard - spinning sections are easy solution. But when something is constantly spinning - maintenance problem started. Friction, you unable to avoid will do hell a lot of problems in connection point, staring from material deterioration and finishing with sealing problem. Again constant check&repair.
So, yeah, hazard level should be a
little bit higher, than on decent habitable planet.
Oh, almost forgot! In game we have planet conditions, which is increase habitability... Damn, i play to much of Stellaris. Ofc HAZARD rating. And some looks like they ask to be applied to stations: No Atmosphere, Extreme Cold, Darkness, Low Gravity.
Stations have no atmosphere and extreme cold around it 100% of times, also no natural gravity (at worst planets have low gravity) and sometimes darkness. But on the planet it will end in 200% hazard at best. But for some reason stations ignore this completely?
Again. Station do have atmosphere (inside) and the bigger it became the less is surface that contact the vacuum.
Stations do not suffer from extreme cold or heat - there are stable temperature inside because of cooling/heating systems, that are not that expensive in maintenance. Yes it's a additional maintenance penalty, but not as big as would be on planet, as it is relatively easy to normalize temperature when surrounding environment is vacuum not surface&atmosphere with thermal conductivity. Consider stations as large thermoses.
Darkness - no more than on planets. Inside of a station is no darker than inside large surface buildings - they all have artificial lighting. So I wouldn't apply this to stations at all.
And gravity... well you can create any gravity you need on stations. So except of minor maintenance penalty - no problems with that.
So, no, I doubt it will be 200%. Rather 125-150%.
