Gefahrstoffkennzeichen

Gefahrstoffkennzeichen, commonly known as hazard symbols or CLP pictograms, are standardized visual warnings used to identify the specific hazards associated with chemical substances and mixtures. These symbols are crucial for ensuring the safe handling, storage, and transportation of potentially dangerous materials. The current system of danger pictograms is largely governed by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which has been adopted and implemented in various regions, including the European Union through the CLP Regulation.

Each pictogram consists of a red diamond border surrounding a black symbol on a white background. These symbols convey specific hazard classes and categories. For instance, the skull and crossbones indicates acute toxicity, the flame signifies flammability or self-reactivity, and the exploding bomb denotes explosives, self-reactives, and organic peroxides. Other common pictograms include the health hazard symbol for carcinogenicity or respiratory sensitization, the exclamation mark for skin irritation or eye irritation, and the corrosion symbol for skin corrosion or damage to metals.

The purpose of these danger pictograms is to provide immediate and easily understandable information to users, even across language barriers. They are typically found on product labels, Safety Data Sheets (SDS), and packaging. Their presence alerts individuals to potential risks, prompting them to take necessary precautions such as wearing appropriate personal protective equipment (PPE), ensuring proper ventilation, and following specific handling instructions to prevent accidents and protect human health and the environment.
