UN Class or Division /  Subsidiary Risks

BENZAL CHLORIDE
98-87-3

On contact with hot surfaces or flames this substance decomposes forming toxic fumes of chlorinated compounds • Reacts violently with strong oxidants or metals • On contact with air it emits corrosive fumes (hydrogen chloride)

6.1

BENZATHONIUM CHLORIDE
121-54-0

On combustion, forms toxic and irritating gases (hydrogen chloride, nitrogen and carbon oxides) • Gives off toxic fumes in a fire

BENZENE CHLORIDE
108-90-7

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

The substance decomposes on heating, on burning and on contact with hot surfaces, producing corrosive and toxic fumes • Reacts with strong oxidants • Reacts violently with chlorates, dimethylsulfoxide and alkali metals causing fire and explosion hazard • Attacks rubber

3

BENZOYL CHLORIDE
98-88-4

The vapour is heavier than air

On contact with hot surfaces or flames this substance decomposes forming highly toxic and corrosive gases (phosgene and HCl) • The substance decomposes violently on heating or on contact with alkalis, amines, other basic compounds, and DMSO, causing fire and explosion hazard • Reacts violently with strong oxidants • Reacts with water or steam producing heat, and toxic and corrosive fumes • Attacks many metals forming flammable hydrogen gas, also on contact with metal salts, alcohols, amines and strong bases

8

100-39-0

6.1/ 8

BENZYL CHLORIDE
100-44-7

The substance will polymerize under the influence of all common metals except nickel and lead, with evolution of corrosive fumes (hydrogen chloride), with fire or explosion hazard • On combustion, forms toxic and corrosive fumes (hydrogen chloride) • Reacts vigorously with strong oxidants • Reacts with water, producing corrosive fumes (hydrogen chloride) • Attacks many metals in presence of water

6.1/ 8

BENZYL CHLOROFORMATE
501-53-1

8
