ADR special provision 290

Radioactive material that also meets another class: excepted-quantity rules, or classification by the predominant subsidiary hazard above 3.5.1.2 limits.

Where radioactive material also meets the definitions of another class in Part 2, this provision decides how it is classified. Within the excepted quantity limits it stays with Class 7 excepted package rules and uses Chapter 3.5 packagings. Above those limits it is classified by its predominant subsidiary hazard and documented under the other class, with the radioactive excepted package name added. Limited quantity rules are then barred, and a special provision exempting the other class sends it back to Class 7.

Conditions

• (a) If it meets the Chapter 3.5 excepted quantity criteria, packagings must follow 3.5.2 and pass the 3.5.3 tests, and the other 1.7.1.5 rules for excepted packages of radioactive material apply, ignoring the other class.
• (b) Above the 3.5.1.2 limits, classify by the predominant subsidiary hazard; the transport document uses the UN number and name of that other class plus the Class 7 excepted package name from Table A column (2), and 2.2.7.2.4.1 also applies. The example given is UN 1993 flammable liquid n.o.s. with the radioactive excepted package wording, class 3, PG II.
• (c) Goods classified under (b) cannot use the Chapter 3.4 limited quantity provisions.
• (d) If a special provision frees the substance from all rules of the other class, use the applicable Class 7 UN number with all of 1.7.1.5.
