NOTES |
---|
The substance may be transported in molten state. Phthalic anhydride molten at a temperature above its flash point, with not more than 0.05% maleic anhydride, shall be classified under UN 3256, hazard class 3, packaging group III. For materials containing more than 0.05% of maleic anhydride the UN number is 2214, hazard class 8, packaging group III. Phthalic anhydride in the solid state and tetra–hydrophthalic anhydrides, with not more than 0.05% maleic anhydride, are not subject to transport regulations. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. Do NOT take working clothes home. |
