SUPPLEMENTARY INFORMATION : On 
February 16, 2021, OSHA published a notice of proposed rulemaking (NPRM) to modify the Hazard Communication Standard (HCS) to align with the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Revision 7, to address specific issues that have arisen since OSHA last updated the HCS in 2012, and to provide better alignment with other U.S. agencies and international trading partners, without lowering the overall protections of the standard. 
The public comment period for this 
NPRM was to close on April 19, 2021, 60 days after publication of the NPRM. However, OSHA received comments from stakeholders requesting extensions of the public comment period (Document ID 0272 (requesting a minimum of 30 additional days), 0274 (requesting a minimum of 30 additional days), and 0276 (requesting extension of 60 days)). The comments state that due to the breadth and complexity of the technical issues involved in this rulemaking, more time is needed to gather data and information and to coordinate responses from organization members to develop more comprehensive and detailed comments. 
OSHA agrees to an extension and 
believes a 30-day extension of the public comment period is sufficient and appropriate in order to address these stakeholder requests. Therefore, the public comment period will be extended until May 19, 2021.
