Mass Decontamination Signs

These pictogram-based signs were developed for Mass Decontamination Units (MDU), and provide essential instructions in a simple format to help victims safely through the decontamination process.

The 24" x 30" images were designed for printing on 13 oz. vinyl banner material with grommets placed in all four corners. For more information about producing these signs for your MDU, please email apc@naccho.org.
