POLYMERIC BEADS, EXPANDABLE. Semi-processed products used to manufacture polymeric articles. These are impregnated with a flammable gas or liquid as a blowing agent and may evolve small quantities of flam-mable gas during transportation.
POLYMERIZABLE MATERIAL. Any liquid, solid, or gaseous material which, under conditions incident to transportation, may polymerize (combine or react with itself) so as to cause dangerous evolution of gas or heat.
PORTABLE TANK. A tank having a capacity of more than 450 L whose shell is fitted with items of service equip-ment and structural equipment necessary for the transport of dangerous goods, that has stabilising members exter-nal to the shell and that is not permanently secured aboard the aircraft. It must be capable of being filled and discharged without the need for the removal of its structural equipment and must be capable of being lifted on and off the aircraft when filled.
POST. See MAIL.
POTASSIUM SODIUM ALLOYS. Are mixtures of metallic sodium and potassium that are solid at ordinary tempera-tures. All mixtures, regardless of physical state, will react vigorously with water and may be self-igniting. The mixtures are all combustible.
POTASSIUM SULPHIDE, ANHYDROUS. A reddish-coloured solid having a strong odour. It is hygroscopic and oxidizes spontaneously on contact with air. Spon-taneous ignition may occur in material improperly packed.
POWDER CAKE, WETTED. Substances consisting of nitrocellulose impregnated with not more than 60% of nitroglycerin or other liquid organic nitrates or a mixture of these.
POWDER PASTE, WETTED. —see POWDER CAKE, WETTED.
POWDER, SMOKELESS. Substances based on nitrocellu-lose used as propellant. The term includes propellants with a single base (nitrocellulose [NC] alone), those with a double base (such as NC and nitroglycerin [NG]) and those with a triple base (such as NC/NG/nitroguanidine). Cast, pressed or bag-charges of smokeless powder are listed under “Charges, propelling” or “Charges, propelling for cannon”.
PREMIXING BURNER LIGHTER. Gas lighter in which fuel and air are mixed before being supplied for combustion, such as lighters producing a blue flame.
P Note: to Premixing burner (“blue flame”) lighters are forbidden for carriage by passengers and crew.
R PRESSURE DRUMS. Are welded transportable pressure receptacles of a water capacity exceeding 150 L and of not more than 1,000 L, (e.g. cylindrical receptacles equipped with rolling hoops, spheres on skids). Not permitted for air transport.
PRESSURE RECEPTACLE. A collective term that includes cylinders, tubes, pressure drums, closed cryo-genic receptacles, metal hydride storage systems and bundles of cylinders.
PRIMERS, CAP TYPE. Articles consisting of metal or plastics caps containing a small amount of primary explosive mixture that is readily ignited by impact. They serve as igniting elements in small arms cartridges, and in percussion primers for propelling charges.
PRIMERS, TUBULAR. Articles consisting of a primer for ignition and an auxiliary charge of deflagrating explosive such as black powder used to ignite the propelling charge in a cartridge case for cannon, etc.
PROJECTILES. Articles such as a shell or bullet which are projected from a cannon or other artillery gun, rifle or other small arm. They may be inert, with or without tracer, or may contain burster or expelling charge or a bursting charge. The term includes:
●Projectiles, inert, with tracer;
●Projectiles, with burster or expelling charge;
●Projectiles, with bursting charge.
PROPELLANTS. Deflagrating explosives used for propul-sion or for reducing the drag of projectiles.
PROPELLANT, LIQUID. A substance consisting of a deflagrating liquid explosive, used for propulsion or for reducing the drag of projectiles.
PROPELLANT, SOLID. A substance consisting of a defla-grating solid explosive, used for propulsion or for reducing the drag of projectiles.
PROPER SHIPPING NAME. The name to be used to describe a particular article or substance in all shipping documents and notifications and, where appropriate, on packagings.
Note:
These names are indicated in bold face characters in the List of Dangerous Goods. See also 8.1.3.
PROTECTIVE BREATHING EQUIPMENT (PBE). Also known as a “smoke hood”, PBE are carried on commer-cial aircraft as part of the safety equipment for flight and cabin crew. PBE contain a small chemical oxygen gener-ator (UN 3356) similar to that found fitted in the cabin for passenger use.
PYROPHORIC LIQUID/SOLID, ORGANIC/INORGANIC.A substance that may ignite in air at or below room temperature in the absence of added heat, shock or friction. All are decidedly combustible and all fume
768
strongly on exposure to air to produce fumes that are somewhat irritating and may be somewhat toxic.
PYROTECHNIC SUBSTANCE. A mixture or compound designed to produce an effect by heat, light, sound, gas or smoke, or a combination of these, as the result of non-detonative, self-sustaining, exothermic, chemical reactions.
PYROXYLIN SOLUTION. Consists of pyroxylin (nitrocellu-lose) or soluble cotton dissolved in amyl acetate or other organic solvents. Pyroxylin solution is used as a basis for the manufacture of lacquer, leather coating compounds, leather substitutes, cements, etc. It is generally more viscous than ordinary lacquers.
QUALITY ASSURANCE. A systematic programme of con-trols and inspections applied by any organization or body, which is aimed at providing adequate confidence that the standard of safety prescribed by these Regulations is achieved in practice.
QUALITY CONTROL. Several production samples selec-ted at random must be tested in accordance with the requirements and frequency described for each type of package. If the requirements are not met, the whole production lot must be rejected unless otherwise speci-fied.
QUANTITY. For packaging tests, quantity means a certain number of random samples, or in certain cases all of each individual type and size, out of a lot or out of a production series.
