The construction busy season is upon us and, unfortunately, so is the blistering heat and humidity.  Heat related illnesses are a serious concern in the construction industry and OSHA has put forth a campaign to raise awareness for prevention.  Heat related illnesses include heat stroke, heat exhaustion, heat cramps, and heat rash, and perhaps more importantly, their symptoms present very dangerous circumstances on a construction job site.  Many of the illnesses can cause fainting, confusion, dizziness, weakness, and other pain, so you can imagine how that would cause issues with someone working 20 feet in the air needing to climb up and down ladders and scaffolds.
