This reminds me of when I used to test mlitary devices for functionality in environmental 
extremes (think it was mil std 810-D back then).  People would see data like the above, and 
ask me to test things at 120 deg and 80% humidity, and I'd tell them that there is no place on 
earth that has such conditions.  Thing is, the 80% humidity you're quoting above probably 
corresponds to the 80 deg temp, but 80 % RH is not possible at either 110 or 120.  The 60% RH 
"may" be possible at 110 deg, but it would be pretty close to a world record, so I'm doubtful, 
even for that area.   At 120, about the highest RH you'd ever encounter is about 40%.   Ie 
likely what happened was that the 60 and 80% RH values were measured when the temperature was 
lower, but when the temperature raised up, the RH went down.  
    The world record dew point is somewhere in the range of 93 deg if I remember right, and I 
believe that one place that was measured was in Kuwait.  So basically at 93 deg, you could 
possibly get 100% humidity, but as the temp goes up from that, the possible (based on world 
record) RH goes down dramatically.
   You are right, however, that high temp/high humidity is quite dangerous.  Before I worked 
in the lab I worked in, someone was killed by being locked in a 95deg/ 100% RH room. With 
those conditions, you can't cool yourself by sweating, and your body temp gets out of control.
