Per the CA Fire Code, if the volume of toxic gas within a given building exceeds a particular amount, then expensive and elaborate gas monitoring and alarm systems are required. Therefore, EH&S works with departments and labs to reduce the volumes of these hazardous materials whenever possible. For an overview of how UC Santa Barbara addresses these concerns, please see the UC Santa Barbara Toxic, Corrosive, and Pyrophoric Gas Program.

Below is a List of Common Toxic Gases that Researchers Could Use.

If you plan to use any of these, or other toxic gases, inform the Lab Safety Specialist at (805) 893-4899, or (805) 893-8243 before you proceed. In most cases the requirements of the Fire Code can be avoided by going to smaller gas cylinders and/or gas mixtures with inert gases.
