filling anhydrous tanks for farmers. I climbed up one tank with the hose in my right hand and tried to pass it to my left behind my back.
In the process, I turned the valve and it sprayed anhydrous all over the back of my legs. I howled and hauled ass across the lot to where we had a big trough full of water. I had to punch through the ice, drop my pants down around my ankles and start splashing water on the back of my legs.
It was about 30 degrees outside. Fortunately I was alone so no one saw my painful humiliation.
That night I had huge blisters on the backs of my legs and I couldn't work for several days.
