Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]:

· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]:

· Inhalation or contact with material may irritate or burn skin and eyes.

These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions. These materials may be nontoxic.
