3. GRSG noted two documents by the expert from Spain (GRSG-127-02 and GRSG-127-05-Rev.1), on behalf of IWG on Boiling Liquid Expanding Vapor Explosion (BLEVE). She explained that IWG was working on reducing the occurrence of BLEVE for the specific case of vehicles transporting dangerous goods (GRSG-127-02). As a result of the IWG efforts, she introduced a first draft (GRSG-127-05-Rev.1) of new requirements and test methods into UN Regulation No. 105 or 107 for automatic fire suppression systems in the engine compartment of specific vehicles. She concluded that the possible adoption of the proposal into one of the two UN Regulations would allow the mandatory compliance of these requirements for specific vehicles under the Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). The expert from Switzerland supported the proposal. A member of the secretary of the Working Party on the Transport of Dangerous Goods (WP.15) explained that fire suppression provisions were already part of annex 13 of UN Regulation No. 107, and that in the future, other categories of vehicles could have similar provisions. He suggested a new UN Regulation could also address this specific issue. The expert from OICA argued that UN Regulation No. 107 did was not suitable due to its scope while the provisions in UN Regulation No. 105 were different. Therefore he suggested that a new UN Regulation would be the most viable solution. The expert from Germany suggested that these provisions be entered into UN Regulation No. 105 or into both UN Regulations Nos. 105 and 107. The expert from Spain clarified that the proposal was based on provisions for internal combustion engines already in UN Regulation No. 107. She added that the purpose of the proposed systems installed on ADR vehicles was to avoid fire propagation to the cargo and therefore more suited to UN Regulation No. 105. As suggested by the Chair, GRSG agreed to establish a Task Force (TF) to further develop such provisions for UN Regulation No. 105 or for a new draft UN Regulation. The expert from Spain volunteered to coordinate and chair the new TF. Finally, GRSG agreed to refer GRSG-127-02 and GRSG-127-05-Rev.1 to TF for future developments.

55. The expert from OICA announced that he would prepare a proposal of amendment to the UN Regulation to align it with new ADR provisions. The expert from Spain clarified that this proposal differed from the activity of flammability in the TF he led (see paragraph 3 above) and reiterated his request to interested parties to liaise with him.
