I have seen a list in the past of the storage tank hazardous area
classification for all different fuels.  I.e. Propane=Class 1 Div 1
groupd D-- I am looking for a listing of other fuels and/or chemicals
for Class 1 Div. 1 (and Div 2) groups A, B, and C.  If you make a
comment, be sure there is a way to get back to you with clarifications
if needed. Had no way to respond to gunner0812 on the last go around.

Hi,

Here is some information that you wanted.

Flammable and Combustible Liquids Storage
Title 29 CFR 1910.106 governs the storage of flammable and combustible
liquids in ASTs.

Flammable liquids are generally defined as those materials with a
flashpoint below 100ø Fahrenheit (F), and are further categorized as
follows:

Class IA - those having a flashpoint below 73ø F and a boiling point below 100ø F 

Class IB - those having a flashpoint below 73ø F and a boiling point
at or above 100ø F

Class IC - those having a flashpoint at or above 73ø F and a boiling
point below 100ø F

Combustible liquids are those with a flashpoint at or above 100ø F.
Combustible liquids are categorized as Class II or Class III as
follows:

Class II - those having a flashpoint at or above 100ø F and below 140ø
F, except any mixture having components with flashpoints of 200ø F or
higher, the volume of which makes up 99% or more of the total volume
of the mixture.

Class IIIA - those having flashpoints at or above 140ø F and below
200ø F, except any mixture having components with flashpoints of 200ø
F or higher, the volume of which makes up 99% or more of the total
volume of the mixture.

Class IIIB - those having a flashpoint at or above 200ø F. 

ASTs used for the storage of flammable and combustible liquids must be
constructed of steel and are required to have been strength tested in
accordance with Title 29 CFR 1910.106(b) before being placed into
service.

Flammable and combustible liquids stored in ASTs may also be subject
to the Risk Management Program (RMP) provisions of the Clean Air Act.
These requirements are found in Title 40 CFR Part 68, Chemical
Accident Prevention Provisions, and are triggered when regulated
chemicals are stored in excess of certain threshold quantity levels as
identified in Title 40 CFR 68.130. Additional information about the
RMP can be found in PRO-ACT's Clean Air Act Risk Management Program
Fact Sheet.
