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

the temperature is 120 degrees, a five minute
exposure could result in third-degree burns.
Forget 75°, just 65°C (150°F) will give you third degree burns in 2 seconds:

I guess I’m long dead, lol.
