(e.g. asymmetrical capacitors) do not belong to this entry.
A187 (362) This entry applies to liquids, pastes or powders, pressurized with a propellant which meets the definition of a gas in 3.2.1.1 and 3.2.1.2(a) or (b).
Note:
A chemical under pressure in an aerosol dispenser must be transported under UN 1950.
The following provisions apply:
(a)the chemical under pressure must be classified based on the hazard characteristics of the compo-nents in the different states:
1.the propellant;
2.the liquid; or
3.the solid.
(b)
If one of the components in (a), which can be a pure
A186
substance or a mixture, needs to be classified as flammable, the chemical under pressure must be to classified as flammable in Division 2.1. Flammable
A188
components are flammable liquids and liquid mix-tures, flammable solids and solid mixtures or flam-mable gases and gas mixtures meeting the following criteria:
1.a flammable gas is a gas which meets the
criteria in 3.2.2.1 of these Regulations;
2.a flammable liquid is a liquid having a flashpoint
of not more than 93°C;
3.a flammable solid is a solid which meets the
criteria in 3.4.1.1 of these Regulations.
(c)gases of Division 2.3 and gases with a subsidiary risk of 5.1 must not be used as a propellant in a chemical under pressure;
(d)where the liquid or solid components are classified as dangerous goods of Division 6.1, Packing Groups II or III, or Class 8, Packing Groups II or III, the chemical under pressure must be assigned a subsidi-ary risk of Division 6.1 or Class 8 and the appropriate UN number must be assigned. Components classi-fied in Division 6.1, Packing Group I, or Class 8, Packing Group I, must not be used for transport under this proper shipping name;
(e)in addition, chemicals under pressure with compo-nents meeting the properties of: Class 1, explosives; Class 3, liquid desensitized explosives; Division 4.1, self-reactive substances and solid desensitized explosives; Division 4.2, substances liable to spontaneous combustion; Division 4.3, substances which, in contact with water, emit flammable gases; Division 5.1 oxidizing substances; Division 5.2, organic peroxides; Division 6.2, Infectious sub-stances or Class 7, Radioactive material, must not be used for transport under this proper shipping name.
A188 (359) Nitroglycerin solution in alcohol with more than 1% but not more than 5% nitroglycerin must be classified in Class 1 and assigned to UN 0144 if not all the requirements of Packing Instruction 371 are complied with.
A189 Except where the defining criteria of another class or division are met, concentrations of formaldehyde solution:
(a)with 10% or more, but less than 25% formaldehyde must be classified as UN 3334 Aviation regulatedliquid, n.o.s.
; and
(b)with less than 10% formaldehyde are not subject to these Regulations.
A190 Neutron radiation detectors containing non-pressurized boron trifluoride gas in excess of 1 g and radiation detection systems containing such neutron radi-ation detectors as components may be transported on cargo aircraft in accordance with these Regulations irres-pective of the indication of “forbidden” in Columns K/L of Table 4.2, provided:
A189 (a) the pressure in each neutron radiation detector must to not exceed 105 kPa absolute at 20°C;
A224 (b) the amount of gas must not exceed 12.8 g per detector and the amount per outer packaging or per radiation detection system must not exceed 51.2 g;
(c)each neutron radiation detector must be of welded metal construction with brazed metal to ceramic feed through assemblies. They must have a minimum burst pressure of 1,800 kPa;
(d)each neutron radiation detector must be packed in a sealed intermediate plastic liner with sufficient ab-sorbent material to absorb the entire gas contents. Neutron radiation detectors must be packed in strong outer packagings that are capable of withstanding a
1.8 m drop test without leakage. Radiation detector systems containing neutron radiation detectors must also include absorbent material sufficient to absorb the entire gas contents of the neutron radiation detectors. Absorbent material must be surrounded by a liner or liners, as appropriate. They must be packed in strong outer packagings unless neutron radiation detectors are afforded equivalent protection by the radiation detection system; and
(e)transport in accordance with this special provision need not be noted on the Shipper's Declaration and a packing instruction must not be shown on the Ship-per's Declaration. The package must be labelled with “Toxic gas” and “Corrosive” hazard labels.
When transported as cargo, neutron radiation detectors containing not more than 1 g of boron trifluoride, including those with solder glass joints, and radiation detection systems containing such detectors where the neutron radiation detectors meet and are packed in accordance with the above conditions, are not subject to these Regulations irrespective of the indication of “forbidden” in Columns J/K and L/M of Table 4.2.
The words “Not Restricted” and the Special Provision number must be included in the description of the substance on the Air Waybill as required by 8.2.6, when an Air Waybill is issued.
A191 Notwithstanding the Division 6.1 subsidiary risk shown in Column C of Table 4.2, the toxic subsidiary risk label and an indication of this subsidiary risk on the Shipper's Declaration are not required when the manufac-tured articles contain not more than 5 kg of mercury.
Transport in accordance with this special provision must be noted on the Shipper's Declaration.
A202 For the purposes of providing life support for aquatic animals during transport, the appropriate authorities of the States of origin, destination and of the operator may approve the carriage of cylinders containing Oxygen compressed, UN 1072 or Air com-pressed, UN 1002, with the valves open to supply a controlled quantity of oxygen or air through a regulator into water containing the aquatic animals. The cylinder or cylinder valve must be fitted with a self-sealing device to prevent uncontrolled release of gas should the regulator malfunction or be broken or damaged. The cylinder must meet those parts of Packing Instruction 200 that apply, except for the need for valves to be closed. In addition, the following conditions apply as a minimum:
