IMDG CODE:

        CLASS: 4.2(6.1)  UN1381 , PG: I

        PSN: PHORPHOURS YELLOW

Packaging as per : CFR 49:

173.188   White or yellow phosphorus.

Phosphorus, white or yellow, when offered for transportation or transported by rail, highway, or water, must be packaged in water or dry in packagings conforming to the requirements of part 178 of this subchapter at the Packing Group I performance level, as follows:

(a) When placed in water, it must be packaged in specification packagings as follows:

(1) Wooden boxes (4C1, 4C2, 4D, or 4F) with:

(i) Inner hermetically sealed (soldered) metal cans, enclosed in other hermetically sealed (soldered) metal cans, or

   内包装要气密的金属桶。

(ii) Inner water-tight metal cans containing not over 0.5 kg (1 pound) of phosphorus with screw-top closures; or

     如果只是水密的金属桶，不能装超过0.5KG

(2) Steel drums (1A1) not over 250 L (66 gallons) capacity each or steel drums (1A2) not over 115 L (30 gallons) capacity each.

    1A1的钢桶不能超过250L, 1A2的钢桶不能超过115L. 什么叫1A1,2?  开口闭口而已。 什么叫开口，闭口，去死了。 不要往下看了。

(b) When dry, it must be cast solid and shipped in packagings as follows:

(1) Steel drums (1A2) not over 115 L (30 gallons) capacity each, or

(2) In projectiles or bombs when shipped by, for, or to the Departments of the Army, Navy, or Air Force of the United States Government, without bursting elements.

请注意，以上没有水覆盖的要求。 但是，实践上，一般要求水覆盖。且水的厚度不要低于20MM.

很多船公司比如APL, 不能接受装2 TIERS 的P4, 我都觉得莫名其妙。我想这恐怕是对层与层之间的衬垫不放心吧。
