UN Class or Division /  Subsidiary Risks

ANISOLE
100-66-3

3

DIETHYL ETHER
60-29-7

The vapour is heavier than air and may travel along the ground; distant ignition possible • As a result of flow, agitation, etc, electrostatic charges can be generated

The substance can form explosive peroxides under the influence of light and air • Reacts violently with oxidants causing fire and explosion hazard

3

DI-n-BUTYL ETHER
142-96-1

As a result of flow, agitation, etc, electrostatic charges can be generated

The substance can form explosive peroxides, especially in anhydrous form • The substance decomposes on heating producing acrid smoke and fumes • Reacts with oxidants • Reacts violently with nitrogen trichloride (NCl3)

3

DIPROPYL ETHER
111-43-3

3

ETHYLBUTYL ETHER
628-81-9

3

ETHYLMETHYL ETHER
540-67-0

2.1

ISOPROPYL ETHER
108-20-3

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

The substance can readily form explosive peroxides if unstabilized and explode on shaking

3

METHYLPROPYL ETHER
557-17-5

3

METHYL-tert-BUTYL ETHER
1634-04-4

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

Reacts violently with strong oxidants causing fire hazard

3

METHYLVINYL ETHER
107-25-5

2.1

PHENYL ETHER
101-84-8

Reacts with strong oxidants, 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
