OSHA states at 1910.37(a)(3) that “exit routes must be free and unobstructed. No materials or equipment may be placed, either permanently or temporarily, within the exit route.” OSHA defines an exit route as “a continuous and unobstructed path of exit travel from any point within a workplace to a place of safety.” [emphasis added] The NFPA 101-2009, “Life Safety Code,” also says that an exit discharge must be free and unobstructed.
