Dangerous as in unhealthy over the long term, or as in acutely life threatening? For women 15% is already unhealthy, but not acutely dangerous.
For men 15% is pretty much ideal for health, but you can get as low as 8-10% before it starts becoming unhealthy.
To be acutely dangerous you need to go much lower as a male, about 4%. That’s how low bodybuilders go, and you occasionally see them collapse on stage (although usually because of dehydration, not low bodyfat)
