The newly revised HazCom standard has observed some major changes. In the latest rule, OSHA has introduced changes in the following areas: 

• Revised hazard classes and classification criteria.
• Changes in labeling allowances. The requirements for “small” and “very small” containers have also changed.
• Labeling provisions for containers have been updated.
• Revised criteria for classifying chemicals
• New information requirements for Safety Data Sheets (SDSs)
• Expanded and updated methods and instructions for classifying certain chemicals

 But what are the changes that are going to be observed in such areas? Below we have mentioned all the changes in detail, so take a quick look.  

• Hazard Classes and Classification Criteria: 

 The Updated hazard classifications now include revised categories for aerosols, desensitized explosives, and flammable gases. It also includes a new category for chemicals under pressure within the aerosols class. 

• Labelling Allowance: 

 Chemical manufacturers must use abbreviated shipped container label information on containers with 100 ml or fewer chemicals. For a 3 ml smaller container only a product identifier would be enough. The outer packing containers must have full shipped information details. 

• Labels for Containers Rereleased for Shipment: 

 Manufacturers, importers, or distributors who learn of new significant hazard information do not need to relabel chemical products that have already been shipped or are ready for shipment (bundled, palletized, etc.). 

• Classifying a Chemical:

 Chemical manufacturers must now consider the intrinsic properties and potential hazards of their products. It also includes those expected from downstream uses when classifying them. These details must be included in Section 2 of the Safety Data Sheets (SDS). 

• Information Requirement for SDSs:

 There are several updates to the information required on Safety Data Sheets (SDSs). These include adding “particle characteristics” to Section 9, ensuring Section 1 contains domestic contact information, and providing updated instructions for chemical manufacturers on what to include in Section 2. 

• Expanded Classification Method:

 New classification methods are now allowed for certain chemicals. It includes oxidizing solids also along with several other categories that have been updated or clarified.
