This close-up view of the Plum Brook Ordnance Works safety exhibit highlights the plant's outstanding safety record — over 17.8 million man-hours worked with no fatal accidents in two years of operation. Rows of illustrated cautionary posters preached vigilance against everyday hazards like ladders, nails, and slippery floors, while a mannequin dressed in full protective gear, including a gas mask and hard hat, demonstrated the personal protective equipment issued to workers at this WWII-era chemical and munitions plant in Sandusky, Ohio.
