The NMAI’s security measures ensure visitor safety and the protection of objects in the museum. Visitors are greeted upon entry to the building by Smithsonian security personnel who conduct a thorough but speedy hand-check of all bags, briefcases, purses, strollers, and containers. All visitors are required to walk through a metal detector. Those who are unable to go through the metal detector will be hand-screened with an electronic wand by security personnel. Help speed entry into the museum by having all purses or bags open and ready for inspection, and pockets emptied before going through the screening station. Please note there may be a line to enter the museum on busy days.
