ABSTRACT:
A safety enclosure is disclosed which provides a portable self-contained ultra clean enclosed space environment, with easy access to the interior of the enclosure and which can be operated at relative positive, zero or negative pressure, depending on the usage conditions required so as to provide biological protection for an animal handler or investigator, to reduce contamination of the material inside the enclosure, and to prevent escape of noxious material to the outside.
