UN Class or Division / Subsidiary Risks

ALLYL GLYCIDYL ETHER
106-92-3

3

EPICHLOROHYDRIN
106-89-8

The substance will polymerize due to heating or under the influence of strong acids, bases and contaminants •On combustion, forms toxic and corrosive fumes •The substance decomposes slowly on contact with water •Reacts violently with strong oxidants •Reacts violently with aluminium, zinc, metal powders, alcohols, phenols, amines (especially aniline) and organic acids causing fire and explosion hazard •Attacks steel in the presence of water

6.1

1,2-EPOXYBUTANE
106-88-7

The vapour is heavier than air and may travel along the ground; distant ignition possible •The vapour mixes well with air, explosive mixtures are easily formed •As a result of flow, agitation, etc, electrostatic charges can be generated

The substance may polymerize on contact with acids, alkalies, tin, aluminium and iron chlorides with fire or explosion hazard

3

1,2-EPOXYPROPANE
75-56-9

3

2,3-EPOXYPROPANOL
556-52-5

The substance decomposes on contact with strong acids and bases, water, salts (aluminium chloride, ferric chloride) or metals (copper, zinc), causing fire and explosion hazard •Attacks plastic and rubber

ETHYLENE OXIDE
75-21-8

6.1 / 2.1

FURFURAL
98-01-1

The vapour is heavier than air

The substance polymerizes under the influence of acid(s) or base(s) with fire or explosion hazard •Reacts violently with oxidants •Attacks many plastics

3

FURFURYL ALCOHOL
98-00-0

The substance polymerizes under the influence of acids •Reacts violently with strong oxidants or strong acids, causing fire and explosion hazard

6.1

TETRAHYDROFURAN
109-99-9

The vapour is heavier than air and may travel along the ground; distant ignition possible

The substance can form explosive peroxides •On combustion, forms carbon monoxide •Reacts violently with strong oxidants causing fire and explosion hazard

3

VINYL CYCLOHEXENE DIOXIDE
106-87-6

On combustion, forms acrid smoke and irritating fumes •Reacts with active hydrogen compounds (eg, alcohols, amines)

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
