1. Technical Field
The embodiments herein generally relate to emergency control mechanisms, and, more particularly, to an emergency safety shutoff system for a glovebox air intake.
2. Description of the Related Art
Environmental accidents, toxic chemical spills, and testing to support verification inspections are examples of situations where chemical and biological testing may be required. Gloveboxes are used for such testing. The availability of safe, reliable, and efficient containment vessels, such as gloveboxes and fume hoods, for conducting environmental tests help to protect the investigators and preserve the evidentiary value of the collected materials and the on-site tests.
The glovebox serves as engineering control and primary protection during a hazardous test operation. During the test, in the event of pressure loss due to power failure or exhaust blower malfunction, there is a potential for containment loss through the air intake valve which would allow for hazardous materials to enter into the operators breathing zone. It is desirable to eliminate the potential hazard with an improved glovebox system.
