Editing Safety data sheet (section)

===United States===
In the [[United States|U.S.]], the [[Occupational Safety and Health Administration]] requires that SDSs be readily available to all employees for potentially harmful substances handled in the workplace under the [[Hazard Communication Standard]].<ref>{{Cite web |title=29 CFR 1910.1200 -- Hazard communication. |url=https://www.ecfr.gov/current/title-29/subtitle-B/chapter-XVII/part-1910/subpart-Z/section-1910.1200 |access-date=2024-10-08 |website=www.ecfr.gov |language=en}}</ref> The SDS is also required to be made available to local fire departments and local and state emergency planning officials under Section 311 of the  [[Emergency Planning and Community Right-to-Know Act]]. The [[American Chemical Society]] defines Chemical Abstracts Service Registry Numbers ([[CAS number]]s) which provide a unique number for each chemical and are also used internationally in SDSs.

Reviews of material safety data sheets by the [[U.S. Chemical Safety and Hazard Investigation Board]] have detected dangerous deficiencies.
 
The board's Combustible Dust Hazard Study analyzed 140 data sheets of substances capable of producing combustible dusts.<ref name="CSB dust study">{{cite web|url=http://www.csb.gov/assets/1/19/Dust_Final_Report_Website_11-17-06.pdf|title=U.S Chemical Safety and Hazard Investigation Board, Investigation Report, Combustible Dust Hazard Study, Report No. 2006-H-1|date=November 2006|pages=38, 88–95|website=Csb.gov|access-date=22 December 2017|archive-date=21 December 2016|archive-url=https://web.archive.org/web/20161221025305/http://www.csb.gov/assets/1/19/Dust_Final_Report_Website_11-17-06.pdf|url-status=dead}}</ref> None of the SDSs contained all the information the board said was needed to work with the material safely, and 41 percent failed to even mention that the substance was combustible.

As part of its study of an explosion and fire that destroyed the Barton Solvents facility in Valley Center, Kansas, in 2007, the safety board reviewed 62 material safety data sheets for commonly used nonconductive flammable liquids.  As in the combustible dust study, the board found all the data sheets inadequate.<ref name="CSB Barton Solvents KS">{{cite web |url=http://www.chemsafety.gov/assets/document/CSB_Study_Barton_Final.pdf |title=Archived copy |access-date=9 December 2012 |url-status=dead |archive-url=https://web.archive.org/web/20121008015433/http://www.chemsafety.gov/assets/document/CSB_Study_Barton_Final.pdf |archive-date=8 October 2012 }} </ref>

In 2012, the US adopted the 16 section Safety Data Sheet to replace Material Safety Data Sheets. This became effective on 1 December 2013. These new Safety Data Sheets comply with the [[Globally_Harmonized_System_of_Classification_and_Labelling_of_Chemicals|Globally Harmonized System of Classification and Labeling of Chemicals]] (GHS). By 1 June 2015, employers were required to have their workplace labeling and hazard communication programs updated as necessary – including all MSDSs replaced with SDS-formatted documents.<ref>{{Cite web|title = GHS Overview - SafeTec|url = http://www.safetec.net/resources/ghs-overview/|website =Safetec.net|access-date = 10 February 2016}}</ref>
