Hazardous materials in vehicles and buildings should be clearly identified using:

• A. Placards
• B. Labels
• C. Tags
• D. Posters

Answer: (A)

Clear, at-a-glance hazard communication relies on visible signs. Placards are large, standardized signs designed to be clearly visible on vehicles and buildings, signaling the hazard class and sometimes the specific material. They let anyone approaching quickly assess the risk and follow the right safety steps, such as avoiding ignition sources and coordinating with responders. Labels and tags serve more for handling and inventory at the item or container level and don’t provide the same broad visibility from a distance. Posters are informational and used for training or warnings, not for marking actual containers or vehicles in transit or storage. Because of their visibility and standardized format, placards are the most effective method for clearly identifying hazardous materials in both transport and facility settings.
