Show answer & explanationAnswer & explanation
Correct answer: A. To standardize hazard identification across international borders.
The primary purpose of GHS pictograms, along with signal words and hazard statements, is to provide a globally consistent and easily understandable system for communicating chemical hazards, thereby standardizing hazard identification and improving safety internationally.
Why the other options are wrong
- B. PPE recommendations are found in SDS Section 8, not the primary function of pictograms.
- C. First-aid instructions are found in SDS Section 4, not primarily communicated by pictograms.
- D. Ingredients and concentrations are found in SDS Section 3, not typically conveyed by pictograms.
GHS Pictogram Purpose
GHS pictograms are standardized graphic symbols used to convey specific hazard information about a chemical, designed for quick recognition and global consistency in hazard communication.
- One of the three main GHS label elements (pictogram, signal word, hazard statement).
- There are nine pictograms, each representing a specific hazard class.
- Aids in quick hazard assessment and understanding.
