1. The entry on "flammable aerosols” has been renamed to “aerosols" given that the HCS no longer defines the former and no longer uses it as a hazard class (but still references it in Appendix C and it appears in some H-statements) . There has been a curious evolution (and inconsistency) in how OSHA has defined the term over the years, so I broke that out into its own subsection: https://www.ilpi.com/msds/ref/aerosol.html2. The Hyperglossary never had an entry for "chemical name" or "common name", as those always seemed kind of self-explanatory. But as HCS 2024 defines both, I developed a new entry that covers a host of terms with subtle nuances that may not be obvious to the lay reader: https://www.ilpi.com/msds/ref/chemicalname.html3. There’s a new entry for “bulk shipment”, another one of those seemingly obvious terms. But it turns out that OSHA has a different definition than DOT and others, and there are a series of nuances involved such as bulk shipment versus bulk packaging: https://www.ilpi.com/msds/ref/bulkshipment.html
These two are a LOT more than a simple update. The pages formerly consisted of simple lists of statements from the HazCom Standard. Now, the tables are done with a modern mobile-friendly style and they provide historical context of the GHS and HCS. For example, you can easily see which ones are listed in the GHS but are not required under OSHA/HazCom, as well as which ones are obsolete. I felt it necessary to track new and obsolete material because one may be working from older source material.Thus, if a new H or P statement was added under a revision of GHS later then Rev 3, there is a clickable badge labeled GHS 4, GHS 7, Obsolete, GHS only (because does not have jurisdiction over that area), etc. so one can understand how the GHS and Standard have evolved with time. Click on the badge to get a brief notation and link to the GHS version.For example:
