List is next:
ethylene glycol (EG), 
diethylene glycol (DEG), 
triethy-lenglycol (TEG)
basicly liquids from polyol groups,
I know alcohols are flammable but what about polyols? and how easily




The USA [legal definition](https://www.osha.gov/dte/library/flammable_liquids/flammable_liquids.html) per [29 CFR 1910.106](https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9752) of "flammable" is:



> 
> Flammable liquid: any liquid having a flash point below 100ºF (37.8ºC)
> 
> 
> 


None of the three substances is flammable by that definition.


The [respective flash points](http://www.dow.com/ethyleneglycol/about/properties.htm) by the Penskey-Martens Closed Cup method are:


Ethylene Glycol: 241ºF (116ºC)


Diethylene Glycol: 310ºF (154ºC)


Triethylene Glycol: 350ºF (177ºC)

Update: Now the rule has been changed to:



> 
> Flammable liquid means any liquid having a flashpoint at or below 199.4 °F (93 °C)
