Here is today's Ham Shack Safety Tip:

  If there is a Heat Advisory, Excessive Heat Watch, or Excessive
  Heat Warning in effect for the area, CANCEL any and all tower
  work...treating it like a day with thunderstorm potential. Hot
  temperatures can lead to heat illness, heat exhaustion, and
  potential heat stroke; the latter can be fatal, if medical help
  is not summoned promptly.
