According to the GHS, which of the following represents a physical hazard?

In the context of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), flammable materials are classified as physical hazards. This classification is based on their ability to ignite and sustain combustion when exposed to an ignition source, posing risks like fires and explosions in various environments. Flammable materials must be clearly labeled and handled with care to ensure safety in workplaces and during transportation.

Corrosive materials, while hazardous, are classified based on their chemical properties rather than physical characteristics. Bacterial pathogens and allergenic substances relate more to health hazards than physical hazards. Understanding these classifications helps in implementing proper safety measures and handling precautions in workplaces to prevent accidents and injuries related to these hazards.
