3173-72-6

The substance decomposes on heating producing toxic fumes (nitrogen oxides)

METHYLENE BISPHENYL ISOCYANATE
101-68-8

The substance may polymerize due to heating above 204 °C or under the influence of temperatures above 204 °C. •On combustion, forms toxic and corrosive fumes including nitrogen oxides and hydrogen cyanide. •Reacts readily with water to form insoluble polyureas. •Reacts violently with acids, alcohols, amines, bases and oxidants causing fire and explosion hazard

6.1

CYCLOHEXYL ISOCYANATE
3173-53-3

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

The substance may polymerize due to heating and under the influence of incompatible materials. •The substance decomposes on burning producing toxic fumes (nitrogen oxides). •Reacts with oxidants and strong bases, water, alcohol, acids and amines

6.1

METHYL ISOCYANATE
624-83-9

The vapour is heavier than air and may travel along the ground; distant ignition possible. •The vapour mixes well with air, explosive mixtures are easily formed

The substance may polymerize due to heating or under the influence of water and catalysts. •The substance decomposes on heating producing toxic gases (hydrogen cyanide, nitrogen oxides, carbon monoxide). •Reacts with strong oxidants. •Reacts violently with water, acids, alcohols, amines, iron, steel, zinc, tin, copper (or alloys of these metals) causing fire and explosion hazard. •Attacks some forms of plastic, rubber and coatings

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
