Industrial Gases Council Activity Report

Transport (WG-1)

o Documents:

o WG1 members have finalized the revision of Doc 81 “Road Vehicle Emergency and Recovery” with its corresponding Training Package TP 08.

o Doc 52: “Load securing of class 2 receptacles” and Doc 63: “Prevention of Tow away incidents” is under revision in 2020

o Transport of temporary imported DOT cylinders:

A long running issue has been the temporary import of cylinders from the United States into Europe, primarily special gases. It appears we will achieve a permanent change in both the US and European transport regulations.

In the meantime, EIGA has assisted in the preparation of a new multilateral agreement that will enable us to continue business. Multilateral Agreement (MLA 318) on the carriage of gases of Class 2 in refillable pressure receptacles authorised by DOT has been now signed by most of the European countries. Its date of expiry is 1 June 2023. This topic should have been discussed at the Bern meeting in March 2020 (postponed due to Covid 19)

o Another point of attention is the Spanish proposal on optical differentiation of labels for gases, with the intent to help the firefighters in case of fire. If approved, this proposal would lead to change the ADR labels for flammable gases on all cylinders and trucks. EIGA as well as the other concerned industries are not in favour of this proposal and are preparing arguments against.

o EIGA has officially raised to the Commission the issue concerning its absence in the TPED Notified Body (NoBo) Group, where topics concerning gas industry are discussed. Each WG-1 member has been invited to contact their national authorities on this issue

o WG-1 is maintaining a permanent watch of the proposals of amendment in the transport regulation and a participation to the ADR international meetings (Bern March 2020 cancelled next meeting September 2020)

Food Gases & CO2 (WG-8)

o Two new representatives from Linde and SIAD replacing previous WG-8 rep.

o Ongoing work (1 web meeting April 2020):

· Doc 67: “CO2 cylinders at users' premises” has been revised and sent for technical review.

· Doc 83: “Recommendations for safe filling of CO2 cylinders and bundles”.

· Doc 125: “Guide to the Supply of Gases for Use in Foods”: this is a key document for food gases. The revision focuses on the difference between food additive and ingredient gases and processing aid gases. It will be updated to refer to new standards in the food sector such as ISO22000 FSSC 22000. The revision of this document also includes an alignment in the terms and definitions used in the Food & CO2 documents with a better clarification about the food gases legal requirements.

· Doc 174: “Guidelines for the Safe Installation and Use of Cryogenic Food Freezing and Cooling Equipment”.

o Food Contact Material (FCM): the European Commission has published a roadmap on the evaluation of the Regulation (EC) 1935/2004 on materials in contact with food in order to assess both the adequacy of existing European legislation and all existing national standards for non-harmonised materials.

Ad-Hoc Group AHG-8.4 prepared a “briefing pack” for Fleishman Hillard in preparation for meeting with DG santé .

Note: the position of the Ministry of Health in Italy was proposed to be included in the briefing pack. The National Research Council of Italy, Florence, produced a study of migration test of the metal contaminants present in the carbon steel cylinder into the food gases. “Migration Processes of Metal Elements from Carbon Steel Cylinders to Food Gases 2014”.

Hydrogen Energy (WG-11)

WG-11 activity is focusing on building common positions within industrial gas companies and other players in the hydrogen (or H2) infrastructure industry, in order to present a common industry view to the various standardisation and regulation bodies. Hydrogen energy is a quite specific activity. The players involved in the H2 infrastructure extend beyond the traditional panel of gas companies. WG-11 regularly includes guests such as Shell, Daimler, BMW, Toyota, Honda, Ford and other players in the field of H2 mobility to support this activity.

The International Standard ISO 19880-1 “General specification for hydrogen refuelling stations” to which WG11 has largely contributed during the past 4 years was published in March 2020.

Last meeting of WG11 was held on March 17 (reformatted as web conference due to COVID 19)

WG11 decided to prepare a position paper on “non communication refuelling”(no information exchange between car and station). Members are emphasising that “communication refuelling” would minimize risks and should be addressed by H2 refuelling station operators.

Meetings scheduled in Feb 2020 with car manufacturers to progress on refuelling risk assessment topic have been postponed due to Covid 19.

WG11 listed the following topics related to establishing the environmental attributes of H2 (the colors of H2) where it may develop a position:

1. Promoting a market based approach instead of a location base approach -> Guarantees of origin that determine the attributes of hydrogen

2. Decarbonisation. The EC thinks that only “green” hydrogen will play a crucial role in the decarbonization. -> Important issue for our industry production plants.

Our sector has a role to play as hydrogen expert. -> develop of a narrative and position for the industrial gases sector about decarbonisation.

3. Emitter Payer Principle.

Acetylene (WG-12)


WG-12 has undertaken the task of revising Doc 123 “Code of Practice – Acetylene” and re-publish it in a set of more manageable shorter documents:

Other topics including regulatory threats / changes:

  • Definition of future EIGA Acetylene Library – ongoing

  • Regulation Watch on DMF Restriction (AHG-12.1) – ongoing

  • Support to WG5 on “Best Available Techniques for Acetylene Production” and “Guidelines for the Management of Waste Acetylene Cylinders” -
