UN Class or Division /  Subsidiary Risks

ETHYLENE GLYCOL DINITRATE
628-96-6

Heating may cause violent combustion or explosion producing toxic fumes (nitrogen oxides) • May explosively decompose on shock, friction, or concussion • Reacts with acids

NITROETHANE
79-24-3

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

3

NITROMETHANE
75-52-5

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

PENTAERYTHRITOL TETRANITRATE
78-11-5

1.1D

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
