Final answer:
The skull and crossbones illustration within a red diamond shape in the GHS system signifies that the substance is toxic.
Step-by-step explanation:
Within the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), a skull and crossbones illustration inside a red diamond shape represents toxic substances.
This symbol is part of the labeling and hazard communication standard, which aims to provide clear and consistent information about the dangers of chemicals.
The GHS symbols, also known as pictograms, are designed to be understandable globally and alert users to the presence of hazardous chemicals that can pose serious health risks, such as toxicity through ingestion, inhalation, or skin absorption.
The skull and crossbones illustration inside a red diamond shape within the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) represents toxic substances.
It is used to indicate that the chemical can cause serious health effects, including death, if it is inhaled, ingested, or comes into contact with the skin or eyes.
For example, a chemical like hydrochloric acid, which can burn the skin, eyes, and clothes, would be labeled with the skull and crossbones symbol.
