UN Class or Division /  Subsidiary Risks

AMYL ACETATE
628-63-7

The vapour is heavier than air

Reacts with oxidants causing fire and explosion hazard • Attacks many plastics

3

sec-AMYL ACETATE
626-38-0

The vapour is heavier than air

The substance decomposes upon burning, producing toxic gases and vapours • Reacts violently with strong acids, strong oxidants, strong alkalis • Attacks many plastics

3

BUTYL ACETATE
123-86-4

The substance decomposes slowly on contact with air or moisture producing acetic acid and n-butanol • Reacts violently with strong oxidants causing fire and explosion hazard • Attacks many plastics and resins

3

sec-BUTYL ACETATE
105-46-4

The vapour mixes well with air, explosive mixtures are easily formed

On combustion, forms toxic gases and vapours (such as carbon monoxide) • Reacts violently with nitrates, strong oxidizers, strong alkalies, and strong acids, causing fire and explosion hazard • Attacks many plastics

3

tert-BUTYL ACETATE
540-88-5

3

CYCLOHEXYL ACETATE
622-45-7

Reacts with oxidants • Reacts on contact with water or humidity to release acetic acid causing in metallic containers a slow corrosion hazard

3

ETHYL ACETATE
141-78-6

The vapour is heavier than air and may travel along the ground; distant ignition possible

Heating may cause violent combustion or explosion • The substance decomposes under influence of UV light, bases, acids • Upon heating, toxic fumes are formed • The solution in water is a weak acid • Reacts with strong oxidants, bases or acids • Attacks many metals in presence of water • Attacks plastics

3

3

METHYL ACETATE
79-20-9

The vapour is heavier than air and may travel along the ground; distant ignition possible, and may accumulate in low ceiling spaces causing deficiency of oxygen

The substance decomposes on heating under influence of air, bases, strong oxidants, water, UV-light, causing fire and explosion hazard • The substance is a strong reducing agent and reacts with oxidants • Attacks many metals in presence of water • Attacks plastics

3
