What group is Diethanolamine in

What group is Diethanolamine in

What group is Diethanolamine in

(OP)
I am working on a refinery job which will have Diethanolamine present. Does anyone know what gas classification this falls under for a CL1 DIV 1 installation. I would be interested to know if there is a web site that lists this information as well.
 

RE: What group is Diethanolamine in

Define the gas being treated before worrying about the DEA.  Let's download an MSDS for diethanolamine.  I'll wait for a minute as I got a head start.

OK, let's look at the flamability and reactivity ratings.  Flammability is 1 or slight; reactivity rating is 2, moderate.

Inhalation: Low vapor pressure makes it a low inhalation hazard unless heated or misted.

Fire Fighting: Flash point 130 degree C (266 degree F; autoignition temperature 662 degree C, 1224 degree F.  LEL 1.6 and UEL 9.8.  Slight fire hazard when exposed to heat or flame.
Explosion: Above the flash point explosive vapor air mixture may be formed.

Boiling point: 269 degree C, 516 degree F, decomposes.
Stability:
Stable under ordinary conditions of use and storage. Hygroscopic. Darkens upon heating above 60C (140F). This product should not be heated above 60C in the presence of aluminum due to excessive corrosion and potential chemical reaction releasing flammable hydrogen gas.
Hazardous Decomposition Products:
Burning may produce carbon monoxide, carbon dioxide, nitrogen oxides.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Carbon dioxide, copper, copper alloys, galvanized iron, halogenated organic solvents, acids, and oxidizing agents. Concentrated solutions or higher temperatures can introduce reactivity hazards. N-nitrosamines, many of which are known to be potent carcinogens, may be formed when this product comes in contact with nitrous acid, nitrates or atmospheres with high nitrous oxide concentrations.
Conditions to Avoid:
Heat, flame, ignition sources, incompatibles, light, and air.

Did you check NFPA 30, 86 and 497?  OK, no joy there.  API 500?  Nope.

Perhaps we should concentrate on other fluids in the area.  What gas is this being used to treat?
