What is the role of the Globally Harmonized System (GHS) in marine cargo operations?

• A. To standardize chemical hazard classification and labeling for safety data sheets and on-package labeling.
• B. To regulate shipping routes
• C. To set shipping fees
• D. To determine cargo tank cleaning intervals

Answer: (A)

Hazard communication for chemicals is standardized. The Globally Harmonized System provides a unified way to classify chemical hazards and to label and create safety data sheets that describe those hazards. In marine cargo operations this matters because the same symbols, hazard statements, and precautionary details appear consistently on shipments and their SDSs anywhere in the world. That uniform language lets crews, dock workers, shippers, and port authorities quickly understand what a cargo can do, what protective measures to take, and what to do in an incident. It guides decisions on handling, storage, segregation, ventilation, and personal protective equipment, and it supports coordinated emergency response. The other options—regulating shipping routes, setting fees, or determining tank cleaning intervals—are not functions of GHS; those are covered by separate transport regulations, commercial practices, and maintenance schedules.
