IATA第50期《危险品规则》（2009）显著修订和变化
（注：中文仅为参考）
1–Applicability 适用性
1.2.3–Exceptions. The exception for aircraft used to transport dangerous goods to provide medical aid to a patient during flight has been clarified. The revised text makes it clear that the aircraft can be one adapted for specialized use, i.e. air ambulance, or may a regular public transport aircraft where the operator approves the carriage.
1.2.3-例外。为了在飞行中向病人提供医疗救援而携带危险品的航空器被明确为例外。修改后的内容明确了此类航空器可以是那些为特殊用途改装的飞机，如飞行医院，或是经运营人同意承运的执行定期航班的公共运输飞机。
1.5–Training Requirements 训练要求
1.5.0.3. There has been a change to the provisions on recurrent training. The recurrency peri
od is still 24 months. However, there is now provision for a 3-month “window” that allows for recurrent training conducted within the final 3 months of the 24-month period to be considered to have been completed on the expiry date of the 24-month period. For example, a person who completed a course on 30 June 2007 needs to complete a revalidation by 30 June 2009. However, the revalidation may be taken between 1 April and 30 June 2009 for the revalidation to be considered to have been completed on 30 June 2009. The next revalidation date will then be 30 June 2011.
1.5.0.3对复训的周期时间要求做补充说明。复训周期仍然是24个日历月，但是，新规定了一个3个月的“窗口”，即允许在培训到期前的3个月内进行复训，即被认为在到期日完成了复训。
如：某人在2007年6月30日接受的危险品培训，应在2009年6月30日前完成复训，但是，复训可在2009年4月1日至6月30日之间的时间内进行，而仍被认为完成复训的时间是2009年6月30日。下一次复训时间应为2011年6月30日。
1.5.3. A new 1.5.3, Training Curricula–“No Carry” Operators has been added. The text and
associated Table 1.5.B reinforces that even operators that have a policy of not carrying dangerous goods as cargo, mail or stores must still provide applicable employees with dangerous goods training.
1.5.3 增加了对不承运危险品的运营人的培训要求。见表1.5B，强调即使运营人的政策是不承运危险品货物、邮件或供应品，仍必须向1.5B表中适用的雇员提供危险品培训。
1.5.5.3. A minimum period of 36 months following the last training date has now been specified for retention of dangerous goods training records.
1.5.5.3 增加培训记录最少36个月的保存期限要求。
1.6–Dangerous Goods Security 危险品的安保
1.6.3.3. The list of high consequence dangerous goods has been revised to include certain explosives assigned to Division 1.4, explosives in Division 1.5, Class 3 and Division 4.1 desensitized explosives.
1.6.3.3 高危危险品的种类有所扩展，增加：

2.7–Dangerous Goods in Excepted Quantities 例外数量危险品
The requirements for excepted quantities have been revised to align with the provisions in t
he UN Model Regulations. This includes the assignment of an “EQ” code from E0 to E5 to identify if a substance is permitted in excepted
quantities, in what quantity per inner packaging and per package. The current IATA Dangerous Goods in Excepted Quantities label has been replaced by a new excepted quantity marking.
为遵守UN《规章范本》（橙皮书），对例外数量危险品的要求进行了修订，包括分配了一个由E0reactive metal到E5的“EQ”代号，以便识别一种物质是否可以例外数量运输，以及内包装和外包装的允许数量。
例外数量危险品标签被更换成新的例外数量危险品标记（见图2.7B)。
2.9.2–State Variations.国家差异
Australia, France, Malaysia, United Arab Emirates, the United Kingdom and the United States have advised of amendments to their State variations.
澳大利亚、法国、马来西亚、阿联酋、英国及美国的国家差异进行了修订。

3.9.2.4. The criteria for classification of environmentally hazardous substances has been aligned with the provisions of 2.9.3 of UN Model Regulations.

4.2 – List of Dangerous Goods 危险品表
The format of Table 4.2 has been revised to accommodate a new column for the “EQ” codes to identify maximum quantity per inner and outer packaging for dangerous goods in excepted quantities in accordance with Subsection 2.7. To accommodate the additional column, the columns for Class or Division (Column C) and subsidiary risk (Column D) have been combined into a single Column C. Any assigned subsidiary risk is shown in parentheses following the primary risk, as is required to be shown on the Shipper’s Declara
tion.
