Which benefit is most cited for GHS over HAZCOM?

The benefit that is most cited for the Globally Harmonized System (GHS) over the existing Hazard Communication (HazCom) standard is the increased standardization in information. GHS provides a consistent and unified system for communicating chemical hazards through standardized label elements and safety data sheets. This uniformity helps to ensure that workers, employers, and emergency responders have the same understanding of hazards regardless of location or regulatory framework.

Standardization simplifies the communication of hazards, making it easier for users to interpret and understand the information provided about hazardous substances. This is particularly beneficial in a global context where chemicals may be transported and used in different countries that adopt GHS, leading to improved safety and reduced risks associated with chemical handling. In contrast, the other options, such as increased documentation, longer training sessions, and higher costs of compliance, are not generally viewed as benefits associated with GHS; instead, they can be perceived as burdens or drawbacks in comparison to the clarity and simplicity brought by standardized information.
