Allen Robert Linder

Thirty-year-old Ashley N. Friedman collapsed while cleaning the inside of the tank of a tanker trailer, which contained residual chemicals on Feb. 20, 2020, in Cleveland. Her mother, who worked with her, was on top of the tanker and screamed for help when Friedman did not respond to her calls. Allen Robert Linder, a 65-year-old truck driver of Milan, Ohio, responded. Without a respirator or air supply, Linder ascended a ladder on the tank’s side and entered the tank through a hatch. Shortly, Linder, too, collapsed. A responding firefighter equipped with a self-contained breathing apparatus entered the tank and assisted others operating a cable hoist to remove Friedman and Linder from the tank. They both died.
