Exhibit techniques must provide a chemically stable environment for the objects. Displayed objects should not be exposed to atmospheric contaminants or exhibit materials containing a substance that may be harmful to the objects. Exhibit techniques must facilitate the desired degree of physical handling of collection objects and, conversely, must protect collections from unnecessary handling. Exhibit cases must be locked or otherwise inaccessible to the visitor. Exhibit techniques must not alter the exhibited object physically or chemically, must not cause irreversible changes to the objects, and must provide adequate physical support and protection for the objects.
Fluctuations are to be minimized within a range of ten points.
Objects should never be exhibited in areas where they would receive direct sunlight. Colored objects, such as textiles, prints, and lithographs, should be protected against ultraviolet light rays produced by sunlight and by fluorescent lighting. Smoking, food and drink should be prohibited in the exhibit areas. Staff should make regular inspections for conservation, pest and maintenance problems in and around the exhibit areas.
