Annex

SPECIAL PROVISIONS

Note: Unless otherwise identified these special provisions are currently in Chapter 3.3 of the UN Model Regulation. Some or part of these are proposed to be incorporated into the packing instructions consistent with the guiding principles for the development of packing instructions adopted by the Sub-Committee. The requirements unrelated to packaging will be retained in Chapter 3.3. The following is a proposed list of the special provisions currently in the Model regulation along with proposed amendments and additional provisions which are necessary to conform to the guiding principles adopted by the Sub-Committee.

15,16, 18 Special provisions (SPs) 15, 16 and 18 are not addressed because even though they specify minimum quantities per package they are directly related to classification. It is proposed that these SPs remain in Chapter 3.3 without amendment.

25	This SP is proposed to be incorporated as P300 (see Annex 1).

29	This substance is exempt from labelling but shall be marked with the appropriate class or division and the packing group. SP 29 should remain in Chapter 3.3. The deleted text should be included in the appropriate packing instructions (i.e. P003, P900, etc.).

Delete SP76 against UN2006

80	This SP currently applies to nitrocellulose entries; UN 2555, 2556, 2557 and 3270. This SP is proposed to be incorporated in P405.

114	This SP only applies to Dipicryl sulphide, wetted, UN 2852. This requirement should more appropriately be placed in a packing instruction according to the agreed upon guidelines. This SP is proposed to be incorporated in P405 as special packing provision P31 (see Annex 1).

117 Subject to these Regulations only when transported by sea. [Fish meal or fish scrap shall not be transported if the temperature at the time of loading exceeds 35oC or 5oC above the ambient temperature, whichever is higher. Fish scrap or fish meal shall contain at least 100 ppm of anti-oxidant (ethoxyquin) at the time of shipment.] The latter two sentences where taken from the IMDG Code. It is proposed that they be added to SP 117.

This is proposed for deletion because it is proposed to be incorporated in P800 for Gallium and Mercury.

132	During the course of transport, this substance shall be protected from direct sunshine and stored (or kept) in a cool and well ventilated place, away from all sources of heat. SP 132 should be retained in Chapter 3.3. The strikeout text is proposed as P408. This applies to UN 2956 and 3251.

DELETE 133

DELETE SP 170 AND 171

This SP is proposed for deletion because it is proposed to be incorporated in P001, as a special packing provision P1. This applies to UN 1133, Adhesives, UN 1210, Printing Ink, UN 1263, Paint and UN 1866 Resin solution (see Annex 1).

201	Lighters and lighter refills shall comply with the provisions of the country in which they were filled. They shall be provided with protection against inadvertent discharge. The liquid portion of the gas shall not exceed 85% of the capacity of the receptacle at 15 C. The receptacles, including the closures, shall be capable of withstanding an internal pressure of twice the pressure of the liquefied petroleum gas at 55 C. The valve mechanisms and ignition devices shall be securely sealed, taped or otherwise fastened or designed to prevent operation or leakage of the contents during transport. Lighters shall not contain more than 10 g of liquefied petroleum gas. Lighter refills shall not contain more than 65 g of liquefied petroleum gas. This SP should be amended by deleting the penultimate sentence. The SP should be retained in Chapter 3.3. The deleted sentence is proposed to be incorporated into packing instruction P003, as a special packing provision P 21.

209	The gas shall be at a pressure corresponding to ambient atmospheric pressure at the time the containment system is closed and this shall not exceed 105 kPa absolute. This SP should be amended by deleting the last sentence. The SP should be retained in Chapter 3.3. The deleted text is proposed for incorporation in packing instruction P201. This applies to UN 3167, 3168 and 3169 (Gas samples).

This SP is proposed to be deleted from Chapter 3.3 and incorporated as P25 in P052. This applies to a number of Type B and C self-reactive substances, UN 3221, 3222, 3223, 3224, 3231, 3232, 3233 and 3234 (see Annex 1).

215	This entry only applies to the technically pure substance or to formulations derived from it having an SADT higher than 75 /C and therefore does not apply to formulations which are self-reactive substances. (For self-reactive substances, see 2.4.2.3.2.4).

Except where packaged according to packing instruction P408(c), the requirements of special provision 181 shall be applied to formulations showing a violent effect in laboratory tests involving heating under confinement.

In SP 216, SP 217 and SP 218 the sentence "Each packaging shall correspond to a design type that has passed a leakproofness test at the Packing Group II performance level." would be deleted. The remainder of the SPs should be retained in Chapter 3.3. The deleted text is proposed to be incorporated as a particular packing provision or exception in P002, P 11 (see Annex 1). This applies to solids containing flammable liquids (UN 3175), toxic liquids (UN 3243) and corrosive liquids (UN 3244).

219	Genetically modified micro-organisms which are infectious shall be transported as UN 2814 or UN 2900. The first sentence of this SP is proposed to be incorporated in P904 as a packing instruction for genetically modified micro-organisms, UN 3245. The reference to 2.6.3.3.4 is not correct since this paragraph does not exist. The Sub-Committee should consider whether the second sentence of SP 219 should be retained in Chapter 3.3 since 2.6.3.1.4(a) also states "Genetically modified micro-organisms which meet the definition of an infectious substance given above shall be classified in Division 6.2 and assigned to UN 2814 or to UN 2900" .

221	Substances included under this entry shall not be of Packing Group I . This SP applies to Medicines (UN 1851, 3248 and 3249) should be retained in Chapter 3.3 without amendment since the quantity per package is a condition of classification and use of the medicines entries.

229	This special provision applies to UN 1057, 1044, 1950, 2037 and 3150. It is proposed that this SP be deleted since it is proposed to be incorporated in P003.

230 In SP 230 paragraph (g) should be deleted. This text would be incorporated in packing instruction P903

This SP would be incorporated in packing instruction P903

233	This SP applies to Elevated temperature solid, n.o.s., UN 3258 only. This SP is proposed to be deleted as P099 (competent authority packing instruction) is proposed to be assigned to this entry.

235	This entry applies to articles which may be classified in Class 1 in accordance with 2.1.1.1, 2.1.1.2 and 2.1.1.3, which are used as life-saving vehicle air bags or seat-belts, when transported as component parts and when these articles as presented for transport have been tested in accordance with Test series 6 (c) of Part I of the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, with no explosion of the device, no fragmentation of device casings, and no projection hazard or thermal effect which would significantly hinder fire-fighting or other emergency response efforts in the immediate vicinity. If the air bag inflator unit satisfactorily passes the series 6(c) test, it is not necessary to repeat the test on the air bag module itself. Air bags or seat-belts installed in vehicles or in completed vehicle components such as steering columns, door panels, seats, etc. are not subject to these Regulations. This SP should be retained in Chapter 3.3. The text proposed to be deleted would be incorporated in packing instruction P902.

236	Polyester resin kits consist of two components: a base material (Class 3, Packing Group II or III) and an activator (organic peroxide), . The organic peroxide shall be type D, E or F, not requiring temperature control, Packing group shall be II or III, according to the criteria for Class 3, applied to the base material. The quantity limit shown in Column 7 of the Dangerous Goods List applies to the base material. It is proposed that this SP be retained in Chapter 3.3 and that the packaging provisions shown in strike out be included in P302.

237	The nitrogen content of the nitrocellulose shall not exceed 11.5%.

Text incorporated into P410

238 In SP 238 the last sentence should be deleted since this is proposed to be incorporated in P801.

239	Except for air transport, batteries or cells shall not contain dangerous goods other than sodium, sulphur and/or polysulphides. Batteries or cells shall not be offered for transport at a temperature such that liquid elemental sodium is present in the battery or cell unless approved and under the conditions established by the competent authority.

Cells shall consist of vapour tight metal casings which fully enclose the dangerous goods and which are so constructed and closed as to prevent the release of the dangerous goods under normal conditions of transport.

Batteries shall consist of cells secured within and fully enclosed by a metal casing so constructed and closed as to prevent the release of the dangerous goods under normal conditions of transport.

Batteries installed in vehicles (UN 3171) are not subject to these Regulations. The SP should be retained in Chapter 3.3. It only applies to UN 3292. This SP should be amended by deleting the second paragraph except for the first sentence and the last sentence of the last paragraph. The text proposed to be deleted is proposed to be incorporated in packing instruction P407.

246	This substance shall be packed in accordance with packing method OP6 (see applicable packing instruction). During transport, it shall be protected from direct sunshine and stored (or kept) in a cool and well-
ventilated place, away from all sources of heat. This SP only applies to 2-Bromo-2-nitropropane-1,3-diol, UN 3231. Although this SP addresses a packaging requirements it is proposed that it be retained in Chapter 3.3 especially since it only deals with one substance.

SP 248 should be deleted and incorporated in packing instruction 117.

251	The entry CHEMICAL KIT or FIRST AID KIT is intended to apply to boxes, cases etc. containing small quantities of various dangerous goods which are used for medical, analytical or testing purposes. Such kits may not contain dangerous goods listed in 3.4.1.

Components shall not react dangerously (see 4.1.1.6). The total quantity of dangerous goods in any one kit shall not exceed either 1 l or 1 kg. The packing group assigned to the kit as a whole shall be the most stringent packing group assigned to any individual substance in the kit.

Kits which are carried on board vehicles for first-aid or operating purposes are not subject to these Regulations. The requirements proposed for deletion would be incorporated in packing instruction P901.

280 In this SP the words "The pressure vessel shall be in compliance with the requirements for the gases, contained in the pressure vessel." would be deleted and incorporated in P202.

284	An oxygen generator, chemical, containing oxidizing substances shall meet the following conditions:

(a)	The generator when containing an explosive actuating device shall only be transported under this entry when excluded from Class 1 in accordance with paragraph 2.2.1.3 of these Model Regulations;

(b)	the generator, without its packaging, shall 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 damage, without loss of its contents and without actuation;

(c)	When a generator is equipped with an actuating device, it shall have at least two positive means of preventing unintentional actuation; and

Paragraph (d) should be deleted since the text is incorporated in P500.

A New SP should be added in Chapter 3.3 for UN 1845 as follows:

XXX	For each shipment by air exceeding 2.3 kg per package, advance arrangements shall be made between the shipper and each carrier. Not more than 200 kg of solid carbon dioxide may be transported in any one cargo compartment or bin on any aircraft except by specific and special written arrangement between the shipper and the aircraft operator.

Transport units containing solid carbon dioxide, when transported on board ocean vessels, shall be conspicuously marked on two sides "WARNING CO2 SOLID (DRY ICE).'' Other packagings containing solid carbon dioxide, when transported on board ocean vessels, shall be marked "CARBON DIOXIDE, SOLID-DO NOT STOW BELOW DECKS.''

Carbon dioxide, solid (dry ice) is excepted from the shipping paper requirements if the package is marked "Carbon dioxide, solid'' or "Dry ice'' and is marked with an indication that the substance being refrigerated is used for diagnostic or treatment purposes (e.g., frozen medical specimens). This is taken from the ICAO TI, PI 904 and the IMDG Code (see page 9025).
