ABSTRACT:
A barrier shield against exposure to environmental contaminants comprises a frame assembly for tensionally retaining a thin resilient film for protection of dental, medical and laboratory workers from sprayed or spattered debris and fluid from the work area, such as a patient's mouth or surgical site. The frame assembly is constructed and mounted so that it may be positionally adjusted by means of a flexible support.
