Glycerols & Glycols: Physical & Chemical Hazards

Chemical Name CAS-Number	Physical	Chemical	UN Class or Division / Subsidiary Risks
1,4-BUTANEDIOL 110-63-4		On combustion, forms toxic fumes (CO) • Reacts with strong oxidants
1,6-HEXANEDIOL 629-11-8	Dust explosion possible if in powder or granular form, mixed with air	On combustion, forms toxic gases
DIETHYLENE GLYCOL 111-46-6		Reacts violently with strong oxidants • Attacks many plastics
ETHYLENE GLYCOL 107-21-1		On combustion, forms toxic gases • Reacts with strong oxidants and strong bases
HEXYLENE GLYCOL 107-41-5		The substance polymerizes • Reacts with strong oxidants
PROPYLENE GLYCOL 57-55-6	The vapour is heavier than air	Reacts with strong oxidants, eg, potassium perchlorate, causing fire and explosion hazard

For UN Class: 1.5 = very insensitive substances which have a mass explosion hazard; 2.1 = flammable gas; 2.3 = toxic gas; 3 = flammable liquid; 4.1 = flammable solid; 4.2 = substance liable to spontaneous combustion; 4.3 = substance which in contact with water emits flammable gases; 5.1 = oxidizing substance; 6.1 = toxic; 7 = radioactive; 8 = corrosive substance
