DIETHYL ETHER |
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 |
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) |

ISOPROPYL ETHER |
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 |

|
METHYL-tert-BUTYL ETHER |
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 |
