I am working as an Office Manager for a Construction management group adding a new south tower onto Ball Memorial Hospital in Muncie, Indiana. The fireproofers have been spraying fireproofing onto the structural steel members. Talk about a dirty job, I don't know how they see to walk! Come check this out Mike!
They are spraying a cementitious fireproofing onto the structural steel to give it a fireproof rating of 2 hrs. It is mixed in a hopper, and fed through a line to a spray gun that splatters it everywhere, creating a large mess and making the workers very dirty. When I saw them the other day, after their shift, you could not tell who they were! Come pay a visit, we'd love to have you and are all huge fans!

I second her request, my uncle owns a fireproofing company and I have labored for him in the past. It involves cement, water and heavy lifting. I was the only one on his crew that cared about keeping myself clean. I mean these guys look like ghosts at the end of a shift. They mix about 200 50lb bags a day in an 8 hour shift and they don't worry about creating dust or a little waste, the dust cloud each mix creates can blind you. Then on the other end it comes out a high pressure hose with an air flow that disperses the mud in a pattern so they can spray it on the structural steel and deck; sometimes as thick as 2 inches. The support staff gets covered head to toe in wet mud. It covers the floor and must be scraped aside constantly. It is kinda like ice skating when walkin on a smooth concrete surface covered with this stuff.
