4.1.6.1.13 Filled pressure receptacles shall not be offered for transport;<br />

(a) When leaking;<br />

(b) When damaged to such an extent that the integrity of the pressure receptacle or its<br />

service equipment may be affected;<br />

(c) Unless the pressure receptacle and its service equipment has been examined and found<br />

to be in good working order; or<br />

(d) Unless the required certification, retest, and filling markings are legible.<br />

4.1.7 Special packing provisions for organic peroxides (Division 5.2) and self-reactive<br />

substances of Division 4.1<br />

4.1.7.0.1 For organic peroxides, all receptacles shall be “effectively closed”. Where significant<br />

internal pressure may develop in a package by the evolution of a gas, a vent may be fitted, provided the gas<br />

emitted will not cause danger, otherwise the degree of filling shall be limited. Any venting device shall be so<br />

constructed that liquid will not escape when the package is in an upright position and it shall be able to<br />

prevent ingress of impurities. The outer packaging, if any, shall be so designed as not to interfere with the<br />

operation of the venting device.<br />

4.1.7.1 Use of packagings (except IBCs)<br />

4.1.7.1.1 Packagings for organic peroxides and self-reactive substances shall conform to the<br />

requirements of Chapter 6.1 and shall meet its test requirements for packing group II.<br />

4.1.7.1.2 The packing methods for organic peroxides and self-reactive substances are listed in packing<br />

instruction P520 and are designated OP1 to OP8. The quantities specified for each packing method are the<br />

maximum quantities authorized per package.<br />

4.1.7.1.3 The packing methods appropriate for the individual currently assigned organic peroxides and<br />

self-reactive substances are listed in 2.4.2.3.2.3 and 2.5.3.2.4.<br />

4.1.7.1.4 For new organic peroxides, new self-reactive substances or new formulations of currently<br />

assigned organic peroxides or self-reactive substances, the following procedure shall be used to assign the<br />

appropriate packing method:<br />

(a) ORGANIC PEROXIDE, TYPE B or SELF-REACTIVE SUBSTANCE, TYPE B:<br />

Packing method OP5 shall be assigned, provided that the organic peroxide (or selfreactive<br />

substance) satisfies the criteria of 2.5.3.3.2 (b) (resp. 2.4.2.3.3.2 (b)) in a<br />

packaging authorized by the packing method. If the organic peroxide (or self-reactive<br />

substance) can only satisfy these criteria in a smaller packaging than those authorized<br />

by packing method OP5 (viz. one of the packagings listed for OP1 to OP4), then the<br />

corresponding packing method with the lower OP number is assigned;<br />

(b) ORGANIC PEROXIDE, TYPE C or SELF-REACTIVE SUBSTANCE, TYPE C:<br />

Packing method OP6 shall be assigned, provided that the organic peroxide (or selfreactive<br />

substance) satisfies the criteria of 2.5.3.3.2 (c) (resp. 2.4.2.3.3.2 (c)) in<br />

packaging authorized by the packing method. If the organic peroxide (or self-reactive<br />

substance) can only satisfy these criteria in a smaller packaging than those authorized<br />

by packing method OP6 then the corresponding packing method with the lower OP<br />

number is assigned;<br />
