Design and Safety Considerations for Gas Delivery Systems
(CS Clean Solutions Inc.)
Providing protection from releases of hazardous gases from gas delivery systems is an area of the facility that is often overlooked. Gas cabinets, VMBs and other distribution devices generally are considered inherently safe by design, and thus do not require any special protection. However, many gases commonly employed are either toxic, pyrophoric, or corrosive. Uncontrolled release of gas from cylinders poses a serious safety threat to both the workplace and the neighborhood, owing to the quantity of pressurized, concentrated gas. This paper reviews the potential associated risks and possible mitigation strategies available to provide failsafe operation.
