|
BENZYL BENZOATE |
The vapour is heavier than air |
On combustion, forms toxic and irritating fumes |
|
|
BUTYL FORMATE |
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 |
Reacts with strong oxidants |
||
|
CARBAMIC ACID, ETHYL ESTER |
The substance decomposes on heating producing toxic fumes (nitrogen oxides) |
||
|
CARBOFURAN |
The substance decomposes on heating on burning |
||
|
DIETHYL CARBONATE |
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 |

ETHYL CHLOROFORMATE |
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 |
