Many of the older homes and buildings in the New Orleans, LA, locale that were destroyed by Hurricane Katrina contained asbestos material (i.e. asbestos roofing tiles, transite siding, insulation, floor tiles, and popcorn ceilings). The U.S. Army Corps of Engineers (USACE) was mandated to follow strict environmental protocols in the demolition of these homes that were designated Regulated Asbestos Containing Material (RACM) demolitions. Warning signs and tape were used to designate the “hot zone” and all non-essential personnel were required to stay on the safe side of the marked area. USDA Photo by Alice Welch.
