a4.3.10.6 hazardous decomposition products
a4.3.10.6 危险分解产品

(a) fire decomposition products
(a) 焚烧分解产物

list known and reasonably anticipated hazardous decomposition products produced as a result of use, storage and heating.
列出已知和有理由预料因使用、储存和加热而产生的危险分解产品。

fire decomposition products are quite extensive and they vary in accordance with factors such as:
55. 焚烧分解产物是非常广泛的，并且因以下因素而有所不同：

however, the tests should be performed on the assumption that the decomposition products will ignite.
不过，进行试验时应当假设分解产物会引爆。

some fire decomposition products, in particular those resulting from incomplete combustion, are persistent organic pollutants.
有些燃烧分解产物，特别是不完全燃烧的产物是持久性有机污染物。

a wide variety of decomposition products are generated during the process of combustion, including (see footnote 24):
54. 在燃烧过程中会产生多种分解产物，包括（见脚注24）：

residues left in the soil after a fire may cause immediate pollution as a result of liquid decomposition products penetrating the soil, or gradual pollution as a result of leaching of ash and other unburned residues.
焚烧后仍存留于土壤中的残余物可以通过两种方式发挥影响，即由液体分解物渗透土壤而引起直接污染，以及由灰烬和其他未燃残余物沥滤而引起逐步污染。

mpfa: methylphosphonofluoridic acid (thermal decomposition product of gb / hydrolysis product of methylphosphonic difluoride (df))
· mpfa：甲基氟膦酸(沙林的热降解产物/甲基膦酰二氟(df)的水解产物)

residues that remain on the soil after a fire can have an impact in two different ways, i.e., immediate pollution caused by liquid decomposition products penetrating the soil, and gradual pollution caused by leaching of ash and other unburned residues.
60. 焚烧后仍存留于土壤中的残余物可以通过两种方式发挥影响，即由液体分解物渗透土壤而引起直接污染，以及由灰烬和其他未燃残余物沥滤而引起逐步污染。

4.2.1.13.8 the emergency-relief devices may be of the spring-loaded or frangible types designed to vent all the decomposition products and vapours evolved during a period of not less than one hour of complete fire-engulfment as calculated by the following formula:
4.2.1.13.8 紧急降压装置可以是弹簧式的或易碎式的，应能将罐体被火焰完全吞没不少于一小时内产生的分解物和蒸气全部排放掉，具体按下式计算：

2. to prevent explosive rupture of metal ibcs or composite ibcs with complete metal casing, the emergency-relief devices shall be designed to vent all the decomposition products and vapours evolved during self-accelerating decomposition or during a period of not less than one hour of fire-engulfment as calculated by the formula in 4.2.1.13.8.
2. 为防止金属中型散货箱或包有完整金属外壳的复合中型散货箱发生爆炸破裂，紧急降压装置的设计应能够将自加速分解或货箱被火焰吞没不少于一小时内产生的分解物和蒸气全部排放掉(按4.2.1.13.8中的公式计算)。
