o Other items in progress worth mentioning:
o BLEVE meetings (lessons learnt from Bologna 08/2018 propane accident): ADR will incorporate some new requirements metal mudguards…but the requirements regarding new road safety technology will be made mandatory in Europe for all heavy vehicles (and not specific to ADR)
o 15 years periodic inspection of tubes in battery vehicles: delayed due position of ECMA(European Cylinder Manufacturers Association)
o UN TDG has created a new WG between authorities, experts and industry (to review regulatory changes to come such as ADR 2021). Two members of EIGA WG1 will represent EIGA in this UN WG.

o Specialty Gases (WG-4)
o Published documents:
§ DOC 188 “Safe Transfer of Toxic Liquefied Gases was finalised” (rev)
§ DOC 30 “Disposal of gases” (rev)
o The work on IGC Doc. 030 Disposal of gases was finally closed at the end of April. (Two previous JWG meetings with CGA scheduled last December and February were cancelled because the quorum was not met. This raises potentially an issue for the work on future harmonized documents in the field of Specialty Gases. In both EIGA and CGA dedicated work groups, there are only a few member companies and the recent merger in the industry will put future work at risk).
o Ad hoc Group AHG-4.10 ISO/TC 158 is involved in the development of ISO 6142-2 Gas analysis — Preparation of calibration gas mixtures - Part 2: Gravimetric method for Class II mixtures. Good progress in establishing a common position. A new ISO work item needs to be created because date was expired.

o Ongoing work on Food Contact Material (FCM) by Ad-Hoc Group AHG-8.4 who will liaise with AHG-M16 “cylinders internal quality”
o 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. 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 ongoing topics (dealt with at ISO and CEN level) are:
Hydrogen quality specifications for Hydrogen Energy
Hydrogen refuelling stations
Hydrogen refuelling protocols and risk assessment => topic of communication/ non-communication refuelling
Another topic being worked on is Hydrogen CO2 footprint (e.g. in the case of carbon capture)
o Acetylene (WG-12)
WG-12 has undertaken the task of revising the comprehensive Doc 123 “Code of Practice – Acetylene” and re-publish its EIGA acetylene library in a set of more manageable shorter documents.

o Other topics:
§ Regulatory Watch on DMF Restriction (AHG-12.1) - ongoing
o HyCO Plants (WG-14)
o This work group is working well as a combined working group with CGA.
§ Doc 230: “Safe Catalyst Handling in HYCO Plants” (new)
Key objectives and initiatives for 2020, industry impact
o Continue activity for EIGA and industry experts in their involvement with ADR and UN TDG regulations; ISO and CEN work on cylinders, valves, vessels, special gases analytical work and hydrogen energy.
o Ensure best practices as detailed in the documents produced are effectively disseminated and implemented.
o Identify gas industry synergies.
o Continue to learn lessons from accidents/incidents.
o Ensure backlog of documents to be revised is controlled and efficiently managed by each WG.
Issues requiring Board guidance
o Hydrogen landscape:
In the framework of revisiting the management of the Hydrogen related topics within EIGA, IGC is considering widening the scope of WG-14 “HyCO” to incorporate other H2 production technologies and other elements of the Hydrogen value chain.
o Nitrous oxide:
Considering the fact that N2O production and distribution have specificities and do not fit well in any existing WG (WG-3 “atmospheric gases”) used to be the “custodian” of the N2O documents, IGC is proposing to set-up a permanent workgroup in which the few “subject matter experts” available in the companies could work together on developing further the safe practices.
o IGC is taking part to the CGA lead YIMA task force to expedite incorporation of lessons learnt into changes to existing harmonized documents specifically:
§ CGA P8/ EIGA Doc 147 “Safe practices guide for cryogenic air separation plants”
§ CGA P8.8/ EIGA Doc 170 “Safe Design and Operation of Cryogenic Enclosures”
§ CGA P8.3/ EIGA Doc 146 “Perlite Management”
