||
|
1,6-HEXANEDIOL |
Dust explosion possible if in powder or granular form, mixed with air |
On combustion, forms toxic gases |
|
|
DIETHYLENE GLYCOL |
Reacts violently with strong oxidants • Attacks many plastics |
||
|
ETHYLENE GLYCOL |
On combustion, forms toxic gases • Reacts with strong oxidants and strong bases |
