Subsidiary Risks

ACETONE
67-64-1

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

The substance can form explosive peroxides on contact with strong oxidants • Attacks many plastics

3

ACETYL BROMIDE
506-96-7

The substance decomposes on heating producing toxic and corrosive fumes • Reacts violently with water and alcohols, causing fire and explosion hazard

ACETYL-CHLORIDE
75-36-5

3

BENZOPHENONE
119-61-9

Reacts with strong oxidants

p-BENZOQUINONE
106-51-4

Dust explosion possible if in powder or granular form, mixed with air • If dry, it can be charged elecrostatically by swirling, pneumatic transport, pouring, etc

Reacts with strong oxidants causing fire and explosion hazard • Reacts violently with strong bases • Above 60 ºC when moist, is self-heating and decomposes giving off toxic gases (carbon monoxide)

6.1

2-CHLOROACETOPHENONE
532-27-4

On combustion, forms toxic and corrosive vapours • The substance decomposes on heating producing corrosive gas (hydrogen chloride)

1-CHLORO-2-PROPANONE
78-95-5

The substance polymerizes slowly under the influence of light • On combustion, forms toxic and corrosive gases (carbon oxides, hydrogen chloride, phosgene) • Reacts with strong oxidants

CYCLOHEXANONE
108-94-1

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

On combustion, forms carbon monoxide • Reacts with oxidants and nitric acid causing fire and explosion hazard

3

CYCLOPENTANONE
120-92-3

The vapour is heavier than air

3

DIACETONE
123-42-2

3

DICHLORACETYL CHLORIDE
79-36-7
