How many specific pictograms has OSHA mandated for chemical labels?

The Occupational Safety and Health Administration (OSHA) mandates eight specific pictograms for chemical labels as part of the Hazard Communication Standard. These pictograms are designed to convey important information about the hazards associated with chemical substances. Each pictogram features a distinctive graphic symbol along with a color-coded background, making it easier for workers to quickly identify the types of hazards a chemical may pose, such as flammability, health risks, or environmental dangers.

The use of these standardized pictograms enhances safety in the workplace by ensuring that employees can recognize and understand hazardous information effectively, regardless of language barriers. This system aligns with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), promoting consistent communication of hazard information across different regions and industries.
