OSHA #511 Occupational Safety and Health Standards for General Industry course

Which hazards are associated with flammable liquids?

1. Frostbite and chemical burns

2. Explosions and fire

3. Electrical shocks and slips

4. Noise and vibration injuries

The correct answer is: Explosions and fire

Flammable liquids pose significant risks primarily due to their ability to ignite easily and produce explosive mixtures with air. When discussing hazards related to flammable liquids, the most critical concerns are explosions and fire. An ignition source, such as a spark or heat, can rapidly ignite vapors emanating from flammable liquids, leading to fires that can spread quickly, and explosions that can occur if a flammable vapor cloud builds up. This risk is exacerbated in environments where these liquids are stored or used improperly, leading to potentially devastating consequences for personnel and property. In contrast, other hazards associated with frostbite and chemical burns are more relevant to substances that are cryogenic or corrosive rather than flammable. Electrical shocks and slips are important safety considerations in general workplace safety, but they are not specific to flammable liquids. Similarly, while noise and vibration injuries concern worker health, they do not pertain to the direct hazards posed by flammable liquids themselves. Thus, the focus on explosions and fire is the most pertinent when considering the risks associated with these substances.
