Class three hazards are primarily concerned with what type of substance?

• A. Gases
• B. Flammable liquids
• C. Flammable solids
• D. Explosives

Answer: (B)

Class three hazards in the context of the Emergency Response Guidebook (ERG) focus on flammable liquids. These substances have a flash point of 60 degrees Celsius (140 degrees Fahrenheit) or lower, which means they can easily ignite and create hazardous conditions. Flammable liquids can lead to fires and explosions if they come in contact with an ignition source. Understanding this classification is critical for emergency responders to ensure they are adequately prepared to handle incidents involving these materials safely and effectively. In contrast, the other options represent different categories of hazards: gases can be classified separately due to their specific risks (like asphyxiation or toxicity), flammable solids also have their own classifications due to their ability to ignite under certain conditions, and explosives are categorized distinctly based on their ability to explode. Each class has unique characteristics and requires tailored approaches for safe handling and emergency response.
