Joint Public meeting Notice: Preparations for the official 41st session of the UN Sub-Committee of Experts on the Globally Harmonized System of Classification and Labelling of Chemicals (UNSCEGHS)

Summary: The UN Subcommittee of Experts on the GHS (UNSCEGHS) will convene its 41st Session in Geneva, Switzerland from Dec. 8-10, 2021. This meeting will be a hybrid meeting, allowing for participation virtually or in person. In light of the few papers submitted for discussion during this session (i.e., only one working paper and one informal paper have been submitted to date), the UNSCEGHS 41st session will have a different format and agenda. The majority of the meeting time will be allocated to discussions on the work of the informal correspondence groups, while the remainder of the time will focus on GHS implementation activities.

Due to the lack of working and informal papers, the U.S.GHS Interagency Group will not hold its usual joint public meeting with the U.S. Department of Transportation (DOT) prior to the 41st Session of the UNSCEGHS. Instead, OSHA will consider post UNSCEGHS outreach to provide an update on the 41st Session and other information regarding the GHS.

Please stay tuned to the HCS Safety and Health Topics webpage;, for upcoming details to be posted in the "Highlights Box".

Please note on Wednesday November 17, 2021, the Department of Transportation (DOT), Pipeline and Hazardous Materials Safety Administration (PHMSA) will conduct a virtual public meeting (See 84 FR 11865, 2019-05892) to discuss proposals in preparation for the 59th session of the United Nations Sub-Committee of Experts on the Transport of Dangerous Goods (UNSCE TDG) to be held November 28 - December 8, 2021, in Geneva, Switzerland. During this meeting, PHMSA is also requesting comments relative to potential new work items that may be considered for inclusion in its international agenda. PHMSA will also provide an update on recent actions to enhance transparency and stakeholder interaction through improvements to the international standards portion of its website.

DATES and TIMES: The PHMSA public meeting will be held on Wednesday November 17, 2021, 2:00 p.m. to 5:00 p.m., ET.
