There are different opinions what yad soledes bo is, but I don’t think anyone holds it is nearly as high as 180. You can get severely burned by water which is much cooler than that.
This is copied from a website I googled:
“Most adults will suffer third-degree burns if exposed to 150 degree water for two seconds. Burns will also occur with a six-second exposure to 140 degree water or with a thirty second exposure to 130 degree water. Even if the temperature is 120 degrees, a five minute exposure could result in third-degree burns.”
I have heard some authorities hold yad soledes bo is even a bit below 110.
