UN Class or Division /  Subsidiary Risks

BENZYL BENZOATE
120-51-4

The vapour is heavier than air

On combustion, forms toxic and irritating fumes

BUTYL FORMATE
592-84-7

The vapour mixes well with air, explosive mixtures are easily formed • As a result of flow, agitation, etc, electrostatic charges can be generated

The substance decomposes on heating or on burning producing acrid and irritating fumes • Reacts violently with strong oxidants

BUTYL PROPIONATE
590-01-2

Reacts with strong oxidants

CARBAMIC ACID, ETHYL ESTER
51-79-6

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

CARBOFURAN
1563-66-2

The substance decomposes on heating on burning

DIETHYL CARBONATE
105-58-8

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

Reacts with reducing material and strong bases • Reacts violently with strong oxidants causing fire and explosion hazard • Attacks many plastics and resins

3

DIETHYLENE BENZYL BENZOATE
120-55-8

The vapour is heavier than air

On combustion, forms acrid fumes

DIMETHYL CARBONATE
616-38-6

3

ETHYL CHLOROFORMATE
541-41-3

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

On contact with hot surfaces or flames this substance decomposes forming hydrogen chloride and phosgene • The substance decomposes on heating producing toxic and irritating fumes including hydrogen chloride and phosgene • Reacts on contact with water or steam producing toxic and corrosive hydrogen • Reacts violently with strong oxidants causing fire and explosion hazard • Attacks many metals especially in the presence of moisture

6.1/ 3/ 8

ETHYL FORMATE
109-94-4

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

Reacts violently with strong oxidants, acids, and bases

ETHYL PROPIONATE
105-37-3

3

METHYL BENZOATE
93-58-3

6.1

METHYL CHLOROFORMATE
79-22-1

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

On combustion, forms toxic fumes (HCl, phosgene) • The substance decomposes on heating or on burning on contact with hot surfaces or flames, this substance causes fire hazard producing toxic and corrosive fumes (hydrogen chloride, phosgene) • Reacts with strong oxidants • Reacts gradually with water, forming corrosive substance (hydrogen chloride)

6.1/ 3

METHYL FORMATE
107-31-3

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

Reacts vigorously with oxidants

3

METHYL PROPIONATE
554-12-1

3

SODIUM FORMATE
141-53-7

The substance decomposes on heating over 253°C into sodium oxalate, hydrogen and carbon monoxide, and on contact with acids producing formic acid vapours

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
