ADR special packing provision PP5
UN 1204 packagings must be built so internal pressure rise cannot cause explosion; no cylinders, tubes or pressure drums.
For UN 1204 under P001, the packaging must be constructed so that an increase in internal pressure cannot lead to an explosion. Cylinders, tubes and pressure drums may not be used.
Note. Appears only in P001. PP8 in P002 has the same effect for UN 2002.
