ETHYLENE GLYCOL DINITRATE |
Heating may cause violent combustion or explosion producing toxic fumes (nitrogen oxides) • May explosively decompose on shock, friction, or concussion • Reacts with acids |
||
NITROETHANE |
Heating may cause violent combustion or explosion • May explode on heating rapidly to high temperature • Shock-sensitive compounds are formed with strong alkalies, acids or combination of amines and heavy metal oxides • On combustion, forms toxic gases (nitrogen dioxide) • The substance decomposes on heating above 300°C producing toxic fumes (nitrogen oxides) • The substance is a strong reducing agent and reacts with oxidants • May attack some forms of plastic |

NITROMETHANE |
The vapour is heavier than air and may travel along the ground; distant ignition possible |
May explosively decompose on shock, friction, or concussion • May explode on heating • The substance decomposes on heating producing nitrogen oxides • Reacts with alkalis causing compound formation which when dry pose explosion hazard • Forms shock sensitive mixture with amines |
