What does the hazard symbol depicting an exclamation mark indicate?

The hazard symbol featuring an exclamation mark indicates a general hazard, specifically pointing to issues such as irritation or sensitization. This symbol is part of the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals, and it serves to alert individuals that the substance may cause non-lethal but notable effects such as skin or eye irritation or respiratory sensitization. It highlights the need for caution when handling these materials to prevent adverse health effects.

The focus on irritation or sensitization distinguishes this symbol from others that convey more severe dangers, such as toxicity, corrosion, or explosive risks, which are represented by different symbols. This emphasizes the importance of recognizing and understanding the specific implications of the exclamation mark symbol in workplace safety and proper handling protocols.
