Geneva, 7-16 December l998,

agenda item 2 (a))

WORK OF THE SUB-COMMITTEE OF EXPERTS

ON THE TRANSPORT OF DANGEROUS GOODS

Multimodal portable tank transport

Portable Tank Requirements

Implementing the Rationalized Approach

Transmitted by the Expert from the United States of America

1.	During its fifteenth session, the Sub-Committee considered a proposal submitted by the Expert from the United States of America (ST/SG/AC.10/C.3/1998/32) to implement the rationalized approach for the assignment of portable tank requirements to individual substances as described in document ST/SG/AC.10/C.3/26/Add.1. A working group was convened and made recommendations which were subsequently adopted by the Sub-Committee. The revised table in Annex 1 (English only) takes these recommendations into account. Revisions to portable tank assignments are shown in bold text.

2. Review of Annex 1 shows that for most substances the assignment of portable tank

requirements is already in line with the rationalized approach. In most cases the resulting changes will have minimal impact on safety and industry. There were a number of changes which were considered more carefully taking into account specific characteristics of some substances and the effects, on existing portable tanks. This is consistent with the guidelines in ST/SG/AC.10/C.3/26/Add.1 which state that: "For certain substances the tank requirements recommended by these guidelines may not be appropriate owing to unique characteristics of the substance not addressed in these guidelines. In these instances expert judgement should be applied in assigning appropriate requirements."

GE.98-

3. In recognition of the amendments to the portable tank assignments and the decisions

taken by the working group the rationalized approach for the assignment of portable tank requirements in document ST/SG/AC.10/C.3/26/Add.1 was also updated and is provided in Annex 2. Several additional T codes were added and some were renumbered to allow for all the possibilities of portable tank arrangements identified in the rationalized approach. Several of these are not used in Annex 1.

Proposal

4. During the IMO DSC Sub-Committee E&T group which met at IMO from 14-23 September 1998, the E&T proposed that PG I and PG II substances which are highly corrosive to steel should not be allowed in portable tanks fitted with bottom openings. This decision is consistent with portable tank assignments currently in the UN Recommendations and IMDG Code but it is not taken into account in the rationalized approach for PG II substances. Since PG I substances are already prohibited to be transported in portable tanks fitted with bottom openings according to the rationalized approach only PG II substances would be affected. Annexes I and II have been amended in accordance with IMO's proposal. The Committee is requested to consider these amendments.

5. The IMO DSC Sub-Committee E&T group also identified a number of substances which are authorized to be transported in portable tanks but do not have tank assignments in the Model Regulation. The expert from the United States proposes that these substances be allowed to be transported in tanks consistent with the rationalized approach. Annex 3 includes a list of these substances with the proposed T Codes and portable tank special provisions.

6.	In previous proposals (i.e. ST/SG/AC.10/C.3/88/Add.1 and ST/SG/AC.10/C.3/32) the expert

from the United States proposed special portable tank requirements for toxic by inhalation substances. These requirements are also included in the proposed portable tank requirements in Annex 1.

7. The Committee is requested to consider the changes resulting from the rationalized approach on the basis of the table provided in Annex 1. The expert from the United States believes that based on the agreement to adopt a grandfather provision to allow continued use of the assignments in the tenth revised edition of the UN recommendations and Amendment 29 to the IMDG Code and considering the amendments proposed in Annex 1, concerns regarding undue burdens on industry will be avoided. The expert from the United States believes that the rationalized approach should be implemented on the basis of the proposed amendments in the Annexes.

8. The following consequential amendments are also proposed:

(a)	Three new portable tank provisions should be incorporated in 4.2.4.3 as follows:

TP27	A portable tank having a minimum test pressure of 4 bar may be used if it is shown that a test pressure of 4 bar or less is acceptable according to the test pressure definition in 6.6.2.1.

TP28	A portable tank having a minimum test pressure of 2.65 bar may be used if it is shown that a test pressure of 2.65 bar or less is acceptable according to the test pressure definition in 6.6.2.1.

TP29	A portable tank having a minimum test pressure of 1.5 bar may be used if it is shown that a test pressure of 1.5 bar or less is acceptable according to the test pressure definition in 6.6.2.1.

(b)	In paragraph 4.2.4.2.5 (see latest revision in ST/SG/AC.10/C.3/28) amend the table to include the following:

Annex 2

GUIDELINES FOR ASSIGNING PORTABLE TANK REQUIREMENTS

TO SUBSTANCES IN CLASSES 3 TO 9

1.	These guidelines for assigning portable tank requirements to substances in Classes 3 to 9 are provided as a reference to be used for assigning portable tank requirements to specific substances. The guidelines were developed taking into consideration the hazards of dangerous goods and their physical and chemical characteristics.

2.	The guidelines provide guidance for assigning specific requirements including minimum test pressures, minimum shell thicknesses, pressure-relief device arrangements and bottom opening closure requirements for portable tanks used to transport substances in Classes 3 to 9.

3.	For certain substances the tank requirements recommended by these guidelines may not be appropriate owing to unique characteristics of the substance not addressed in these guidelines. In these instances expert judgement should be applied in assigning appropriate requirements. For example bottom openings may not be appropriate for substances corrosive to ship structures.

4.	The guidelines are provided in two parts. Part I provides general guidance. Part II provides specific guidance for groups of substances organized on the basis of the Class or Division, Packing Group and subsidiary risk.

Part I

General Guidelines

5.	In assigning tank requirements to a substance the following should be taken into account:

5.1	Prohibited Substances: Some substances should be prohibited from transport in portable tanks. These substances are considered too dangerous for transport typically because of their instability or because they pose an unacceptably high level of risk when transported in bulk quantities under normal conditions of transport. The following substances are prohibited from transport in portable tanks:

-	Substances of Class 1;

-	Desensitised explosives in Division 4.1;

-	Self-reactive substances (other than type F) and related substances of Division 4.1;

-	Organic peroxides of Division 5.2 other than type F;

-	Radioactive materials other than Low Specific Activity (LSA) non-fissile or fissile excepted materials.

Additional prohibited substances are specifically identified in the Model Regulations. Furthermore, some substances may only be transported on the basis of an approval by the competent authority.

5.2	Minimum Shell Thicknesses: The minimum shell thicknesses prescribed are provided in thicknesses relevant to reference steel with a guaranteed minimum tensile strength of 370 N/mm2 and a guaranteed minimum elongation of 27%. When other materials are used equivalent thickness calculations should be performed. Minimum thicknesses range from 5 mm to 10 mm. Part II of the guidelines provide guidance for assigning minimum thicknesses. Granular or powdered solid substances of PG II or III may be transported in tanks with minimum shell thicknesses of 5 mm in the reference steel regardless of the tank diameter when 6.6.2.4.2 is specified relevant to a given substance. Regardless of the minimum thickness specified in Part II, if the thickness determined in accordance with the provisions of sections 6.6.2.4 is greater, the greater thickness shall be applied.

5.3	Corrosive Effects of Substances on Materials of Construction: The minimum thicknesses prescribed do not take a substance's corrosive effects into account. The consignor must ensure that the tank materials of construction are compatible with the lading.

5.4	Minimum Test Pressures: Irrespective of the pressure assigned in these guidelines, the minimum test pressure assigned to an individual substance should be the greater of the pressure determined on the basis of the definitions in 6.6.2.1 of the Model Regulations and the pressure assigned in these guidelines.

5.5	Pressure-Relief Devices Requirements: Two pressure relief device requirements are possible,

(1) Normal (N) (where the provisions of paragraph 6.6.2.8.1 apply);or

(2) 6.6.2.8.3.

When paragraph 6.6.2.8.3 is referenced, a frangible disk must be provided in series preceding the pressure relief device. Paragraph 6.6.2.8.3 should be assigned to substances that:

-	have the potential to polymerize or to produce solid or highly viscous substances capable of preventing proper operation of the relief valve;

-	meet the inhalation toxicity criteria at the PG I level.

In addition, 6.6.2.8.3 is also specified for individual substances as specified in the dangerous goods list based on the decisions of the Committee of Experts.

5.6	Bottom Openings: Three possible bottom opening arrangements are proposed, 6.6.2.6.3 (which indicates three serially mounted means of closure), 6.6.2.6.2 (two serially mounted means of closure) or NA (Not Allowed). [Bottom openings are not allowed for PG I and II substances which are highly corrosive to steel].

5.7	Filling Limits: Three different filling restrictions are possible. The filling limits are considered operational requirements. The filling limits do not have a direct relationship to the construction of the tank or the arrangement of the service equipment. On this basis, filling limits are not addressed in Part II of this Annex and will not be included in the tank type designations. The maximum filling limit for a substance should be consistent with the provisions under "Filling" in Chapter 4.2 of the Model Regulations. The shipper of the dangerous goods has the ultimate responsibility for assuring portable tanks are not filled in excess of the specified limits for each substance, solution or mixture transported.

5.8	Molten Substances: Assignments for molten substances of all classes should be based on the requirements established for liquids of the same class, division, packing group and subsidiary risk of the substance.

Part II

Specific guidelines for assigning portable tank requirements to groups of substances

In assigning tank requirements to a substance the following shall be taken into account:

6.1	For substances in CLASS 3, PG III without a subsidiary risk the following requirements shall apply:

Portable tank instruction	Minimum

test pressure	Minimum shell

thickness	Pressure

relief device	Bottom openings
T2 or T4	1.5 bar */	6.6.2.4.2	Normal	6.6.2.6.3

*/	A higher minimum test pressure may be required depending on the absolute vapour pressure of the substance at 65 °C and the pressure prescribed using the definitions for design and test pressure in paragraphs 6.6.2.1 of the Model Regulations (T4). A minimum test pressure of 2.65 bar applies for n.o.s. entries (T4).

6.2	For substances in CLASS 3, PG III with a Division 6.1 or a Class 8 subsidiary risk the following requirements shall apply:

Portable tank instruction	Minimum

test pressure	Minimum shell

thickness	Pressure

relief device	Bottom openings
T4 or T7	2.65 bar /	6.6.2.4.2	Normal	6.6.2.6.3

*/	A higher minimum test pressure may be required depending on the absolute vapour pressure of the substance at 65 °C and the pressure prescribed using the definitions for design and test pressure in paragraphs 6.6.2.1 of the Model Regulations (T7). A minimum test pressure of 4 bar applies for n.o.s. entries (T7).
