Name one common physical hazard.

Flammable liquids are a common physical hazard because they can easily ignite and cause fires or explosions if not properly handled, stored, or disposed of. These liquids have a low flash point, meaning they can produce enough vapor to ignite at relatively low temperatures. This characteristic poses significant risks in workplaces where flammable substances are used, especially in industries such as manufacturing, construction, and laboratories.

Understanding flammable liquids as a physical hazard is important for implementing safety measures. This includes proper labeling, storage in suitable containers away from potential ignition sources, and adequate training for employees on handling procedures and emergency response measures. Awareness of the risks associated with flammable liquids is essential for minimizing accidents and ensuring a safe working environment.

As for the other options, while they do represent hazards, they may not fit all definitions or contexts regarding what constitutes a physical hazard in the same direct manner as flammable liquids.
