UN Class or Division /  Subsidiary Risks

BENZOYL PEROXIDE
94-36-0

May explosively decompose on shock, friction, or concussion • May explode on heating • On combustion, forms irritating and toxic fumes and gases of benzoic acid and carbon monoxide • The substance decomposes on heating at 103 °C • The substance is a strong oxidant and reacts violently with combustible and reducing materials • Reacts violently with many organic and inorganic acids, alcohols and amines causing fire and explosion hazard • Attacks some forms of plastics, rubber or coatings; fires and explosions may result

tert-BUTYL HYDROPEROXIDE
75-91-2

May explode on heating • The substance is a strong oxidant and reacts violently with combustible and reducing materials, metallic and sulphur compounds

CUMENE HYDROPEROXIDE
80-15-9

May explode on heating at about 150 °C • On combustion, forms toxic gases • Upon heating, toxic fumes are formed • The substance is a strong oxidant and reacts violently with combustible and reducing materials, causing fire and explosion hazard • Contact with copper or lead alloys and mineral acids may lead to violent decomposition

5.2

DICUMYL PEROXIDE
80-43-3

DIISOPROPYL PEROXYDICARBONATE
105-64-6

DODECANOYL PEROXIDE
105-74-8

5.2

HYDROGEN PEROXIDE
7722-84-1

The substance decomposes on warming or under influence of light producing oxygen, which increases fire hazard • The substance is a strong oxidant and reacts violently with combustible and reducing materials causing fire and explosion hazard particularly in the presence of metals • Attacks many organic substances, eg., textile and paper

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
