Word for when something is unsafe but not fatal

Is there a word for when something is unsafe but unfatal too? Like you could get injured from it but it won't kill you. For example

Climbing that ladder would be very X

or

Those old stairs look very X

where x is the word that means it's unsafe but nonfatal.

I've considered unsafe and dangerous, but both of them could be used to describe something fatal. If the word could describe something fatal it won't do. I tried searching 'unsafe nonfatal' in a couple of different dictionaries from the list, along with searching 'dangerous' in the thesaurus but I couldn't find anything.

Solution 1:

hazardous. TFD

• Marked by danger; perilous.
• Depending on chance; risky.

As in:

"skydiving is a hazardous sport"; "extremely risky going out in the tide and fog"; "a wild financial scheme"

Solution 2:

It sounds like you want to communicate the possibility of harm rather than the certainty of fatality. "Perilous" might be an option but risky is more commonly used.
As Brad points out, if something can cause injury then there is also the possibility that the injury might be fatal so we cannot say that you might be injured but it is impossible to be killed.

Climbing that ladder would be very risky

Or

Those old stairs look very risky

risky

Full of the possibility of danger, failure, or loss.
'it was much too risky to try to disarm him

Solution 3:

Treacherous.

Treacherous is a pretty common word and works in both of your situations.

unstable or insecure, as footing.
dangerous; hazardous:

Climbing that ladder would be very treacherous.

Those old stairs look very treacherous.
