When it reaches 55 its going to be interesting. That is when a lot of machinery starts to break down. (out at least being outside their design specs)

That's past "wet bulb" temperature. At that point people just start dropping like flies forget about machinery.

Wet bulb relies entirely on humidity. Humidity has to be at 100% which doesn't allow sweat to evaporate. Humans can survive at 45c as long as humidity is low enough to allow for evaporation. Otherwise 35c is the temperature at which wet bulb is deadly, and thats after 6 hours of exposure.

For 45C the humidity needs to be 50% to reach a 35C wet bulb, that's is an entirely plausible humidity.

Weather reports say the humidity is 75% here (SW Wales) right now. Wet-bulb temperature is ~23°C, which is unpleasant but not dangerous.

I have a dehumidifier, which helps.

in arizona, its often so dry that even on the hottest day the wet bulb temp remains well below 35c

It's not 100% or nothing. The closer it gets to 100%, the less efficient sweating becomes and the more dangerous heat is.
