III. Classification criteria and related hazard communication

(agenda item 2)

A. Recommendations made by the Sub-Committee on its twenty-fifth, 

twenty-sixth and twenty-seventh sessions

Document: ST/SG/AC.10/C.4/2014/13 (Secretariat)

8. The Sub-Committee confirmed the decisions taken at its 25th, 26th and 27th 

sessions on the basis of the consolidated list prepared by the secretariat (see annex I).

B. Work of the Sub-Committee of Experts on the Transport of Dangerous 

Goods (TDG)

1. Physical hazards

(a) Classification of polymeric beads, expandable (UN No. 2211)

Document: ST/SG/AC.10/C.4/2014/14 (CEFIC)

Informal documents: INF.12 (CEFIC)

INF.31 (Secretariat)

9. The Sub-Committee endorsed the recommendation of the TDG Sub-Committee to 

include a test method for substances evolving flammable vapours as a new section 38.4 in 

the Manual of Tests and Criteria. The proposed test method in document 

ST/SG/AC.10/C.4/2014/14 with the amendments listed in INF.31 was adopted (see 

ST/SG/AC.10/42/Add.2).

10. It was noted, however that although the scope of the test is currently limited to 

polymeric beads fulfilling the description of UN No.2211, it might need to be extended to 

other substances and mixtures evolving flammable gases. It was also noted that 

classification and hazard communication of substances and mixtures evolving flammable 

gases are a matter of particular interest for the supply and use and workplace sectors (and in 

particular for storage). 

11. The Sub-Committee decided to examine the need for hazard communication 

associated with the hazards of flammable gases evolved from substances and mixtures and 

entrusted the work to the practical classification issues informal working group. 

(b) Desensitized explosives

Document: ST/SG/AC.10/C.4/2014/16 (Germany)

Informal documents: INF.4 and INF.11 (Germany)

INF.31 (Secretariat)

12. The Sub-Committee noted that the TDG Sub-Committee had endorsed the proposal 

for the introduction of a new chapter on desensitized explosives in the GHS as well as the 

relevant test method as contained in document ST/SG/AC.10/C.4/2014/2 considered at the 

27th session. 

13. The proposal for the new chapter and consequential amendments to the GHS in 

document ST/SG/AC.10/C.4/2014/16 were adopted with a minor amendment to the 

decision logic 2.17.1 (see annex I).

(c) Flammable gases

Informal documents: INF.5/Rev.1 (Belgium and Japan)

INF.10 (CEFIC)

INF.31 (Secretariat)

14. The Sub-Committee endorsed the decision of the TDG Sub-Committee to accept the 

offer from the experts from Belgium and Japan to lead an informal working group dealing 

with categorization of flammable gases, on the understanding that experts from both subcommittees would participate in the work and that the informal working group would report 

to both sub-committees. The Sub-Committee also endorsed the mandate for the work 

proposed in paragraph 6 of INF.5/Rev.1 with the insertion of the words “within Category 

1” after “GHS subdivisions” in sub-paragraph (a).

15. The expert from Belgium invited all delegations wishing to participate in the work 

of the informal group to contact him and said that the first meeting was expected to be held 

in Brussels in March 2015 at a date still to be confirmed. He said that he would explore 

other means to facilitate participation by those unable to travel.

(d) Water-reactivity

Informal documents INF.18 (United States of America)

INF.31 (Secretariat)

16. The Sub-Committee was informed that the report “HM-14: Test procedures and 

classification criteria for release of toxic gases from water-reactive materials” had been 

issued by the United States Transportation Research Board and was available online. 

Experts were invited to review the report, to invite laboratories to conduct trials to verify 

the results and ensure test reproducibility, and to provide comments to the expert from the 

United States of America. 

17. The Sub-Committee noted that work on water-reactivity would continue in the

biennium 2015-2016 and that the TDG Sub-Committee had agreed to keep this item on its 

programme of work for that period (see annex III). 

(e) Classification of polymerizing (stabilized) substances

Informal document: INF.31 (Secretariat)

18. The Sub-Committee was informed that the TDG Sub-Committee had finalized the 

work on classification of polymerizing (stabilized) substances and took note of the related 

provisions adopted by the TDG Sub-Committee to be included in the 19th revised edition 

of the Model Regulations. 

19. Noting that some of these provisions could also be useful for other sectors, the 

expert from the United States of America volunteered to study them in detail and to 

consider whether it would be appropriate to address this hazard in the GHS. She welcomed 

comments from other experts and said that she would consider submitting a proposal on 

this issue during the next biennium.

(f) Classification of substances and mixtures which in contact with water emit flammable 

gases

Informal document: INF.31 (Secretariat)

20. The Sub-Committee endorsed the recommendation from the TDG Sub-Committee 

to align the criteria for the maximum rate of evolution of flammable gas applicable to 

Division 4.3 substances, packing group III (Category 3 in the GHS) in Chapter 2.4, 

paragraph 2.4.4.3.3 of the Model Regulations and in Table 2.12.1 (Chapter 2.12) of the 
ST/SG/AC.10/C.4/56

8

GHS with the criteria in Section 33.4, paragraph 33.4.1.4.4.1 in the Manual of Tests and 

Criteria (see annex I).

2. Other relevant issues

(a) Classification and hazard communication provisions for crude oil

Informal document: INF.31 (Secretariat)

21. The Sub-Committee was invited to take note of the information provided by IPIECA 

in information document INF.37, submitted to the 46th session of the TDG Sub-Committee 

following discussions at a previous session on the information provided in 

ST/SG/AC.10/C.3/2014/49 on rail accidents involving crude oil in North America.

(b) Revision of Chapter 2.8 of the Model Regulations

Documents: ST/SG/AC.10/C.4/2014/12 (Netherlands)

ST/SG/AC.10/C.4/2014/18 (United States of America)

Informal documents: INF.3 (Netherlands)

INF.6 and INF.7 (CEFIC)

INF.20 (United States of America)

INF.21 (Canada)

INF.24 and INF.25 (Netherlands)

INF.29 (Netherlands, CEFIC)

INF.31 (Secretariat)

22. The Sub-Committee noted the outcome of the discussions of the TDG SubCommittee contained in INF.31 and concurred with it that further work would be necessary 

in the next biennium before a final decision on how to address the issues raised could be 

envisaged.

23. With regard to the TDG Sub-Committee’s request to include an item in the 

programme of work of the Sub-Committee for the revision and simplification of a 

methodology for the application of the additivity approach, including professional 

judgement and weight of evidence, several experts considered that a more detailed 

description of the scope and aim of the revision as well as any other issues to be addressed 

was needed before a decision could be taken. In the absence of this information the SubCommittee considered it inappropriate to include a specific item on its programme of work 

and invited the TDG Sub-Committee to come back with a detailed proposal for the next 

session. It was made clear that the absence of a specific item in its programme of work 

would not prevent the Sub-Committee from considering any issues related to corrosivity 

criteria that might be brought to its attention.

(c) Applicability of in vitro tests for the assessment of substances and preparations to be 

assigned to Class 8 (corrosive substances)

Informal document: INF.31 (Secretariat)

24. The Sub-Committee noted that the TDG Sub-Committee had deferred the decision 

on the proposal contained in INF.13 (TDG, 46th session) to the next biennium. The SubCommittee also noted that the TDG Sub-Committee would also need to consider how to 

deal with new versions of OECD Test Guidelines. It was noted that the current practice for 

other standards (e.g. ISO) is that updating of references is done only following 

consideration of the differences between the old and the updated versions and assessment of 

the suitability of the new provisions and their implications. 
ST/SG/AC.10/C.4/56

(d) Wording regarding the hazard class “corrosive to metals”

Informal document: INF.31 (Secretariat)

25. The Sub-Committee took note of the decision of the TDG Sub-Committee to keep 

the words “when tested on both materials” in Chapter 2.8, paragraph 2.8.2.5 (c) of the 

Model Regulations and noted that as a consequence of this decision, no amendments to the 

same text in Chapter 2.16, table 2.16.1 of the GHS were necessary.

C. Practical classification issues

Informal document: INF.32 (United States of America)

26. The Sub-Committee noted that the informal working group had continued to work 

on the items listed in sub-paragraph 2 (a), (b) and (c) in INF.32 and that the additional items 

listed in sub-paragraphs 2 (d) to (j) had been identified as areas where further work was 

needed. 

27. The Sub-Committee agreed to endorse their consideration by the informal working 

group during the next biennium (see annex III). 

D. Work of the TDG-GHS working group on corrosivity criteria

28. Corrosivity related matters were discussed in the plenary session of the TDG and the 

GHS Sub-Committees with participation of experts from both bodies (see paragraphs 22 

and 23).

29. The Sub-Committee shared the TDG Sub-Committee’s appreciation for the work 

done by all those who participated in the work of the joint TDG-GHS working group, in 

particular to its chairman and to the expert from the Netherlands. 

30. Acknowledging that the joint working group had achieved all the progress possible 

at this stage, the Sub-Committee endorsed the view of the TDG Sub-Committee that the 

activities of the joint TDG-GHS working group should be discontinued for the time being. 

Work on corrosivity would continue in each Sub-Committee, on the understanding that the 

sub-committees could reactivate the joint working group in the future if need be.

E. Dust explosion hazards

Informal document: INF.26 (United States of America)

31. The Sub-Committee took note of the report of the meeting of the informal working 

group on dust explosion hazards held on 10 December, as follows:

• The informal working group started consideration of the questions listed in 

Appendix A to Annex II in informal document INF.26.

• Following an intervention from the expert from Argentina about the scope of the 

work of the informal working group as regards the applicability of the GHS to grain, 

flour and cereal, it was pointed out that the work undertaken by the informal 

working group fell within the scope of the GHS, as explained in its Chapter 1.1, 

section 1.1.2 and specifically in paragraph 1.1.2.4. The informal working group was 

of the opinion that consideration of changes to the scope of the GHS was not within 

the mandate of the informal working group, and therefore concluded that any 

questions about the applicability of the GHS to dusts originating from grain, flour or 

cereal should be raised at Sub-Committee level.
ST/SG/AC.10/C.4/56

10

• The informal working group agreed to continue the work by teleconference 

(tentatively scheduled in February and April 2015).

32. During an intervention in the plenary session, the expert from Argentina expressed 

concern about the inclusion of dust originating from food and agricultural products such as 

flours, grains and cereals under the definition of “combustible dust”, on the grounds that 

neither flours, grain nor cereal were chemicals, and that the dust originating from them did 

not have intrinsic hazardous properties (i.e.: it was not dangerous in itself). For these 

reasons he believed that these products should be explicitly excluded from the GHS. The 

expert from Brazil shared this view.

33. Other sub-committee experts however did not agree with this interpretation since 

they considered that the GHS currently does not exempt any product, nor should it in the 

future. They pointed out that the GHS specifically notes in 1.1.2.4 that although 

pharmaceuticals, food additives, cosmetics and pesticide residues in food will not be 

covered by the GHS in terms of labelling at the point of intentional intake, they will be 

covered where workers may be exposed and in transport if potential exposure warrants. In 

addition, they recalled that it is in the purview of each competent authority to decide the 

building blocks and overall scope that would be covered within their jurisdictions. 

34. The chair invited the expert from Argentina to consider submitting an official 

document to the Sub-Committee should he wish to pursue this issue further.

F. Aspiration hazard: viscosity criterion for classification of mixtures

Document: ST/SG/AC.10/C.4/2014/23 (IPPIC)

35. The Sub-Committee agreed to keep this item in its programme of work for the next 

biennium (see annex III).

G. Nanomaterials

Document: ST/SG/AC.10/C.4/2014/25 (France)

Informal document: INF.28 (France)

36. The Sub-Committee noted that the informal working group would focus its work on 

the classification of some selected nanomaterial substances. The informal working group 

stressed the importance of exchanging information with OECD on available classification 

data.

37. The Sub-Committee agreed to keep this item in its programme of work for the next 

biennium. The terms of reference for the work of the group agreed by the Sub-Committee 

at its 26th session remained unchanged (see annex III).

H. Miscellaneous

1. Pyrophoric gases

Document: ST/SG/AC.10/C.4/2014/17 (United States of America)

Informal document: INF.31 (Secretariat)

38. The Sub-Committee noted that the TDG Sub-Committee had confirmed its 

endorsement of the inclusion of pyrophoric gases as a hazard category within the hazard 

class “flammable gases” of the GHS, following consideration of the answers provided by 

the expert from the United States of America to the questions raised at its 45th session. 
ST/SG/AC.10/C.4/56

11

2. Updating of references to OECD guidelines

Informal document: INF.14 (OECD)

INF.31 (Secretariat)

39. The Sub-Committee agreed with the updates proposed in INF.14 with the following 

exceptions (see annex I):

(a) The Sub-Committee agreed to introduce the reference to OECD guideline 

460 in note (d) under Figure 3.3.1 but considered that the text of the last two 

sentences was still relevant and did not agree to its deletion;

(b) The insertion of additional text in the note against the reference to OECD test 

guidelines 484 (in Chapter 3.5, paragraph 3.5.2.6) and 204 (in Appendix V, 

section 2) was not considered necessary on the grounds that the GHS 

considers all data and is test method neutral. The Sub-Committee concluded 

that the existing note was no longer necessary and agreed to its deletion.

40. The Sub-Committee also noted that the TDG Sub-Committee had agreed to endorse 

the consequential amendment to paragraph 2.9.3.2.5 in Chapter 2.9 of the Model 

Regulations pending the decision of the Sub-Committee on the insertion of the reference to 

Test Guideline 123 in paragraph 4.1.1.5 of Chapter 4.1 of the GHS. Since the amendment 

was adopted, the secretariat was requested to amend the text of the Model Regulations 

accordingly.

41. On the question of whether or not references to standards should include the year of 

issuance, the Sub-Committee concurred with the TDG Sub-Committee on the importance to 

date test methods as well as on the need to be informed when an update was available. This 

would allow experts to consider the updates made, assess their implications and check 

whether they are consistent with the provisions they support. 

IV. Hazard communication issues (agenda item 3)

A. Revision of section 9 of Annex 4

Document: ST/SG/AC.10/C.4/2014/21 (Germany)

Informal document: INF.13 (Germany)

42. The Sub-Committee noted that the group had finalized its work and adopted the 

proposal in Annex 1 to document ST/SG/AC.10/C.4/2014/21 as amended by INF.13, for a 

revised section 9 in Annex 4 of the GHS, as well as the consequential amendments to Table 

1.5.2 contained in Annex 2 (see annex I).

43. It was noted that the order of items in Table 1.5.2 was not mandatory and that the 

competent authority had the discretion to prescribe a specific order or leave the choice to 

the person responsible for the preparation of the Safety Data Sheet. 

B. Labelling of small packagings

Document: ST/SG/AC.10/C.4/2014/22 (CEFIC)

Informal document: INF.27 (CEFIC)

44. The Sub-Committee adopted the proposed example to be included in Annex 7 of the 

GHS with some minor editorial corrections (see annex I).
ST/SG/AC.10/C.4/56

12

45. The Sub-Committee agreed to keep this item on its programme of work for the next 

biennium and noted that the group intended to develop additional examples (see annex III). 

C. Improvement of annexes 1 to 3 and further rationalization of 

precautionary statements

1. Corrections to precautionary statements

Document: ST/SG/AC.10/C.4/2014/20 (United Kingdom)

46. The Sub-Committee adopted the proposed corrections without modification (see 

annex II).

2. Work of the informal working group on the improvement of annexes 1 to 3

47. The Sub-Committee noted that the informal working group, at a meeting held on 

11 December 2014 had considered and agreed the revised terms of reference for its 

programme of work for the next biennium. These would include:

(a) Continuing work to reduce the number of precautionary statements on 

“seeking medical advice/attention” and “calling a poison center/doctor” by 

introducing some adjustments to the precedence principles in A3.3.2.2 and 

A3.3.4.6 of the GHS. 

(b) Detailed consideration of the introductory texts to annex 3 and the 

development of additional examples.

(c) Addressing the issue of minor linguistic variations in hazard and 

precautionary statements which do not affect the obvious meaning of these 

statements. The informal working group will identify and collect examples 

and will provide comments on a document on this issue submitted by the 

European Aerosol Federation for consideration by the informal working 

group.

48. The Sub-Committee endorsed the proposed terms of reference for the work of the 

informal working group for the next biennium (see annex III).

D. Miscellaneous

Large GHS pictograms not in labels on portable tanks and multiple element gas 

containers (MEGC) during transport

Document: ST/SG/AC.10/C.4/2014/24 (DGAC)

Informal document: INF.34 (DGAC)

49. The Sub-Committee adopted the proposal for a new paragraph 1.4.10.4.4 as 

amended in INF.34 with some additional modifications (see annex I).

V. Implementation of the GHS (agenda item 4)

A. Development of a list of chemicals classified in accordance with the 

GHS

Informal document: INF.22 (United States of America)
ST/SG/AC.10/C.4/56

13

50. The expert from the United States of America provided a summary report on the 

outcome of the meeting of the informal working group which met on 11 December 2014, as 

follows:

(a) The pilot classification work plan set out in Annex I to INF.22 was agreed;

(b) Three chemicals were selected for the first round of the classification 

exercise:

(i) Dimethyltin dichloride (CAS No. 753-73-1)

(ii) Dicyclopentadiene (CAS No. 77-73-6)

(iii) Di-n-butyl phthalate (CAS No. 84-74-2)

(c) The timeframe for the classification exercise would be as specified in INF.22 

(paragraph 4).

(d) The proposed programme of work for the biennium 2015-2016 outlined in

INF.22 (paragraph 10) was agreed.

51. The informal working group recalled that the aim of the classification exercise at 

this stage was to investigate the feasibility of the process and the resources needed to 

achieve consensus on the application of the classification criteria to the available data.

52. The informal working group also discussed how industry participants could 

participate in discussions at OECD during the pilot exercise. The representative from 

OECD encouraged them to participate, to the extent possible, on the basis of common 

positions representing the views of the industrial sectors involved with a common 

spokesperson. Where there were alternative views, it would be possible for multiple

Informal document: INF.31 (Secretariat)

66. The Sub-Committee noted the outcome of the discussions on this issue at the 46th 

session of the TDG Sub-Committee. Views were divided among experts. While some were 

of the opinion that the TDG Sub-Committee should be entrusted with the work as the GHS 

focal point for physical hazards, others considered that the issues to be solved were mainly 

related to hazard communication and therefore they should be addressed directly within the 

GHS Sub-Committee. Some others did not share this view since they considered that it was 

not possible at this stage to foresee whether or not it would be necessary to amend the 

classification criteria.

67. The Sub-Committee agreed to the proposed scope for the revision as contained in 

paragraphs 10 to 13 of document ST/SG/AC.10/C.4/2014/15.

68. After some discussion on procedural issues, the Sub-Committee agreed to entrust the 

revision to the TDG Sub-Committee, with the following procedure:

(a) The expert from Australia would lead the first developments of the work in 

an intersessional informal correspondence working group with participation 

from experts from both sub-committees. 

(b) The proposals from the informal correspondence group would be submitted 

to the Working Group on Explosives for consideration.

until a final proposal was ready to be submitted for adoption by both subcommittees.

69. It was noted that in view of the workload of the Working Group on Explosives, it 

would have two additional meetings during the next biennium. The Expert from Australia 

was invited to liaise with Mr. Ed de Jong (Chairman of the Working Group on Explosives) 

to organize the work.
