UN Class or Division /  Subsidiary Risks

ACETAMIDE
60-35-5

The substance decomposes on heating, producing toxic fumes • The solution in water is a strong base, it reacts violently with acid and is corrosive • Reacts with oxidants, reducing agents, bases, and acids

ACRYLAMIDE
79-06-1

The substance may polymerize violently due to heating or under the influence of light • The substance decomposes on heating producing toxic gases (nitrous oxides) • Reacts violently with oxidants

6.1

2-CHLOROACETAMIDE
79-07-2

The substance decomposes on heating producing toxic fumes including nitrogen oxides and chlorine • Reacts with strong oxidants, strong reducing agents, strong acids and strong bases

CYCLOPHOSPHAMIDE
50-18-0

The substance decomposes on heating, on contact with moisture, light, producing toxic fumes • Reacts with strong oxidants, strong acids, strong bases

DIMETHYL ACETAMIDE
127-19-5

The substance decomposes on heating producing toxic fumes (nitrogen oxides) • Attacks many plastics

DIMETHYL CARBAMOYL CHLORIDE
79-44-7

8

DIMETHYLFORMAMIDE
68-12-2

On combustion, forms toxic gases (carbon monoxide, dimethylamine and oxides of nitrogen) • Reacts with oxidants

3

N,N'-ETHYLENE BIS(STEARAMIDE)
110-30-5

Dust explosion possible if in powder or granular form, mixed with air

On combustion, forms toxic gases • The substance decomposes on heating and on burning producing toxic fumes (nitrogen oxides) • Reacts with strong oxidants

FORMAMIDE
75-12-7

On combustion, forms toxic gases (nitrogen oxides) • The substance decomposes on heating at 200 °C or above producing ammonia, water, carbon monoxide and hydrogen cyanide • Reacts vigorously with oxidizing materials • Attacks copper and natural rubber • Incompatible with iodine, pyridine and sulfur trioxide

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
