Personal Exposure Limits for DGA

[jensen41455]

I have been looking for a couple of weeks now and I can't find any information on Personal Exposure Limits for Diglycolamine. We use both DGA and TEG (Triethylene Glocol) in our plant and I was able to find the PELs for TEG, but I can't find anything on DGA. Both of them are Huntsman products and Huntsman lists a PEL for TEG, but not for DGA. Their MSDS that they supply for DGA makes it sound like just looking at the stuff can kill you, but the MSDS I get from my distributor doesn't sound near as bad. If I'm not mistaken isn't Huntsman legally required to provide the end user this information to comply with OSHA regulations?

Is DGA know by other chemical names, I see it used for diethylene glycol ethyl ether acetate for one?

Do you have a CAS number?

PELs are set by OSHA, NIOSH, ACGIH in the US. It's tough to search the databases without an exact reference.

The answer to your liability question is "yes" -- the supplier has to give you this info, but if there is not an official agency PEL set up, the manufacturer has to come up with it.

Good on ya,
