What is the purpose of GHS pictograms in chemical safety communication?

• A. They replace written hazard statements with symbols.
• B. They visually convey hazards to improve recognition and understanding.
• C. They classify hazards only by physical form, not health effects.
• D. They are optional components of chemical labeling.

Answer: (B)

Pictograms give hazards a quick, universal visual cue, making the risk easy to recognize and understand at a glance. Each symbol matches a hazard class—flammable liquids, acute toxicity, corrosive substances, environmental hazards, and more—so someone can grasp the type of danger without reading long text. This rapid recognition guides immediate safety actions, such as wearing appropriate PPE, avoiding heat or ignition sources, ventilating an area, or preventing release. They complement the written hazard statements, providing a fast initial alert while the full details can be consulted from the label or safety data sheet. These pictograms are required elements of labeling, ensuring consistent communication across languages and settings.
