Ventilated gas cabinet for storing and distributing highly toxic gases

Particularly Toxic Gases The gases in the following list are extremely toxic and may require that special engineering controls, not ordinarily found in a laboratory, be installed before these gases can be used. Prior to ordering one of these gases, a research protocol review form (found on the OEHS web site) must be completed and reviewed/approved by the Office of Environmental Health and Safety. The following table outlines typical control procedures required for use and storage of particularly hazardous gases: Gas Cylinder Size/Type Frequency of Use Control Procedures Small size cylinders (that can fit inside hood) Either periodic or constant (regardless of frequency) Use and storage in hood Small size cylinders (that cannot fit inside hood) or Large size cylinders Infrequent use Leak testing. Air monitoring during use. Large size cylinders Regular Use Use and store in gas cabinets. Constant air monitoring. Alarm system.
