ADDITIONAL PACKING REQUIREMENTS FOR COMBINATION PACKAGINGS

a) The generator, without its packaging, must be capable of withstanding a 1.8 m drop test onto a rigid, non-resilient, flat and horizontal surface, in the position most likely to cause actuation, without loss of its contents and without actuation. For portable breathing equipment (PBE), which are in a vacuum-sealed bag as part of their containment system, this test may be conducted on the PBE in the vacuum-sealed bag.

b) When a generator is equipped with an actuating device, it must have at least two positive means of preventing unintentional actuation as follows:

 1) mechanically actuated devices:

    i) two pins, installed so that each is independently capable of preventing the actuator from striking the primer;

   ii) one pin and one retaining ring, each installed so that each is independently capable of preventing the actuator from striking the primer; or

  iii) a cover securely installed over the primer and a pin installed so as to prevent the actuator from striking the primer and cover.

 2) electrically actuated devices: The electrical leads must be mechanically shorted and the mechanical short must be shielded in metal foil;

 3) for PBE:

   i) a pin so as to prevent the actuator from striking the primer; and

  ii) placed in protective packaging such as a vacuum-sealed bag;

c) The generator(s) must be transported in a package which will meet the following requirements when one generator in the package is actuated:

 1) other generators in the package will not be actuated;

 2) packaging material will not ignite; and

 3) the outside surface temperature of the completed package will not exceed 100C.

d) Packagings must meet the Packing Group II performance requirements.

Note.- To enable tests 1), 2) and 3) to be conducted on PBE, it is acceptable to break the vacuum-sealed bag to actuate the generator before placing it in the package.
