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
