Which hazard class is associated with the placard label 'Flammable liquid/combustible'?

• A. Flammable liquid/combustible
• B. Poison gases
• C. Radioactives
• D. Corrosives

Answer: (A)

The key idea here is that placards tell you what hazard class you’re dealing with and what kind of risk to expect. A placard labeled “Flammable liquid/combustible” signals a fire hazard from liquids that are flammable or may be combustible. In hazmat terms, that points to Class 3 (flammable liquids) and, for liquids with higher flash points, Class 4 (combustible liquids). The important distinction is the flash point: flammable liquids have flash points below 60°C, while combustible liquids have flash points at or above 60°C. So seeing this placard means you should treat the material as capable of igniting and focus on preventing ignition sources and using appropriate fire response, while also checking the shipping papers for the exact classification. This placard is not for poison gases, radioactives, or corrosives, which use different placards and indicate different hazards.
