SDS Missing Flammability Limits
SDS Missing Flammability Limits
(OP)
Hi guys,
I'm working on a project requiring us to analyze various storage & process vessels to ensure their relief and vent locations are indeed a safe location. While we've received an SDS for all the fluids, most of these datasheets classify the fluid as flammable and then fail to show the flammability limits. This appears to be the norm rather than the exception, and research online hasn't yielded much results. Additionally, the vendors/manufacturer's have frequently come back and said "we don't have that data" which seems pretty surprising to me.
If a material is classified as flammable, are the flammability limits not required to be published? Or why does the vendor/manufacturer not have to be able to provide this information? The same experience applies to the toxicological side as well. I've seen some equations for estimating LFL/UFL in Perry's, but I believe this are based on simple hydrocarbons, which is not what I'm looking at.
Thanks

To a ChE, the glass is always full - 1/2 air and 1/2 water.

Most of what we're looking at are various types of siloxanes. The published data for these chemicals appears to be sparse.

This came up when I googled "flammability of siloxanes", maybe the paper's citation section will turn up something for you. And it's not even behind a paywall to boot!
"Thermal stability and flammability of silicone polymer composites"
http://www.sciencedirect.com/science/article/pii/S...
Googled "estimating flammability limits of siloxanes", this paper has the words "silanes/siloxanes" in it but I've forgotten my ACS login so I can't download it
"Chemical Structure-Based Model for Estimation of the Upper Flammability Limit of Pure Compounds"
http://pubs.acs.org/doi/pdf/10.1021/ef100207x
I never really thought siloxanes presented an appreciable fire risk...learn something new.
