This vs That

HazCom — GHS labeling and Safety Data Sheets (SDS) is often confused with the OSHA HCS regulation for Process Safety Management (PSM). While both topics are related to hazardous materials management, PSM focuses on preventing releases of highly hazardous chemicals, whereas HazCom — GHS labeling and SDS focuses on communicating the hazards of chemicals to workers.

Time-Saver Hack

When classifying chemicals as hazardous or non-hazardous, use the GHS criteria to determine whether the chemical meets the criteria for classification.
