5. The expert from the Republic of Korea introduced GRSG-128-08, explaining that Vehicles of Classes II, III and B shall be fitted with escape hatches, in addition to the emergency doors and windows. However, he added that hatches should not be fitted in positions where technical components were installed (e.g. high voltage systems, systems containing dangerous liquids or gas, etc.). So, he asked for clarification if exemptions would be allowed in these cases. The expert from the United Kingdom explained that the definition of escape hatches in the UN Regulation was not clear. He suggested that such definition should be the egress from the vehicle to the outside. The expert from Australia clarified that escape hatches are fitted for roll-over so that they should be placed on the roof or on the floor. The expert from France suggested that when space was constrained, there should not be exemption and evacuation should be pursued in any case. GRSG agreed to resume discussion at its April 2025 session in an aim to reach a final conclusion on this subject.
