ここでは事故の危険があります。

I understand that the additional は to で and に is just to add a form of
contrast. However, what I am confused about is that why is で used instead of に
when the sentence contains "あります". To my understanding, に is most often used
when あります is present.

Why is では used here in this case instead of には？

particle-で には
Difference of では　vs　には in this sentence context
It's because the speaker grasps it as a phenomenon where some accident might
happen.

For example, when you say 事故があった (there was an accident), what you really
imagine is not so much a scene where something static is left there as one
where people do something. That makes you lean toward で.

answer
When actions are performed in a location often で is used. 家で寝ている, 公園で遊んでいる. So
my guess (given the lack of context) in this case the writer was trying to
emphasize accidents caused through activities in this location, rather than
just the location itself.
