Toxic Gas Ordinance (TGO) Data Table | Stanford University EH&S

How to use this tool

Disclaimer

The information contained within this table is for use by Stanford University personnel only. This information is not provided as advice, opinion, or statement of fact and is not provided for use in any way outside of Stanford University. Any use of the information within this table, except by Stanford University personnel, is at the risk of the user only.

Warning

If you use or handle a liquid or solid material as a gas, consult with the University Occupational Health & Safety Program at EH&S (723-0448) to determine if the material is regulated under TGO.

Santa Clara County Toxic Gas Ordinance regulates materials (i.e. gases, liquids and solids) if the material falls under the definition of Class I, Class II or Class III material and meets either of the following criteria:

It is shipped in compressed gas cylinders, and the material is or becomes or acts as a gas upon release at normal temperature and pressure (70F and 760 mm Hg) or;
The material is used or handled as a gas whether or not the material meets the definition of a compressed gas in Article 2 of the TGO or 49 CFR Section 173.300(a).

Table-Related Column Information

SU# -- Stanford University Number is an unique chemical identifier used in the Stanford Chemical Safety Database.

State -- The physical state of the chemical designated by "G" for gas, "L" for liquid, and "S" for solid.

Name -- A chemical name commonly used to identify the chemical. Note that most chemicals have several name synonyms; it is best to identify the chemical uniquely using the SU# and/or CAS Number.

CAS Number -- Chemical Abstract Service Number is a proprietary unique identifier used to absolutely identify a chemical.

VP -- Vapor Pressure (in mm of Hg) of the chemical.

MW -- Molecular Weight of the chemical.

TOX Type -- Toxicological information related to determining the lethal concentration (LC in PPM) or immediately dangerous to life and health (IDLH in PPM) level of a chemical. TYPE refers to the data source such as LC50 data based on a rat test group.

Exposure -- Refers to the concentration (in PPM) to which the test group was exposed or the concentration at which an exposure becomes immediately dangerous to life and health. Exposure data are converted to LC50 Rat.

TGO Class -- The Toxic Gas Ordinance Class (Class I, Class II, Class III, or NR) designation for the pure chemical, i.e., 100% concentration.

Class 2 -- The percent concentration below which a TGO Class I becomes a TGO Class II.

Class 3-- The percent concentration below which a TGO Class II becomes a TGO Class III.

NR -- The percent concentration below which a TGO Class III becomes a TGO NOT REGULATED. Note that a pure Class I chemical diluted to below a concentration such that it is "not regulated" chemical still must meet the TGO provisions related to "flow limiting devices" and "fire extinguishing systems."

Storage Group -- There are 11 different groups (A B C D E F G J K L and X) that Stanford has identified for safe storage of chemicals. These are the same storage groups provided in the Stanford Chemical Safety Database.
