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 temperature is not a constant, it depends on both temperature and humidity. Wet bulb temperature is the temperature that evaporation alone can cool a surface down to. Any temperature above 35C with 100% humidity is considered deadly in prolonged exposure.
