My husband works on roofs, in attics, under houses and in some very tight spaces. He installs & repairs air conditioning & heating. He has to avoid mice, rats, spiders, insects & their excrement. He has to crawl in attic spaces and under homes in 115 degrees or more. It's hot, smelly & dirty. His clothes are covered in dirt, sweat, grime, and other unmentionables. Long hours, carrying 100 pound equipment up onto roofs or into attics. Cutting holes in drywall & running duct work.
