Proposal to improve the specifications for LPG multi-valves in response to an LPG vehicle fire that resulted in injuries to first responders. A German Type Approval Authority (KBA) analysis concluded that the hose connecting the PRV/PRD of the multi-valve to the gaseous phase was damaged and hose-fragments blocked both PRV and PRD such that pressure could not be adequately reduced. The PRV and PRD were activated, but the fragments considerably reduced the effective section of the relevant tubing and prevented the release of pressure. This proposal aims to prevent such occurrences.

Proposal to introduce new provisions on the location on the vehicle of the filling unit in order to address

• Difficulties with filling the LPG container (e.g., the filler pistol may be unable to fit the space between ground and filling unit when the vehicle is fully laden)
• Risks involved on occupational health and safety of LPG container filling operators (e.g. necessity to kneel or lie down to fill the fuel containter).

Proposals to amend or supersede the proposal in document GRSG-116-05. Liquid Gas Europe opposes the proposal to add an odorant in the n-pentane.

Proposal to insert new provisions on the location on the vehicle of the filling unit, marking of the LPG container date of production, and a limitation on the maximum service life of LPG containers to 15 years.

Alternative solution from OICA to the German proposal GRSG/2017/16 regarding visibility/access requirements for PRV/PRD-related components in order to improve maintenance and reduce the risk of critical failures of pressure relief devices. The proposal also proposes amending provisions of the ageing test in Annex 15 in response to concerns over failures of rubber hoses.
