Placard color red indicates which hazard?

Placard color red indicates which hazard?

• A. Health Hazard
• B. Explosive
• C. Oxidizer Reactive
• D. Flammable

Answer: (D)

The main idea here is that placard colors convey the hazard class, helping you recognize risks at a glance. Red on a placard signals a flammable material (Class 3). That means the substance can ignite easily and you should avoid ignition sources, control heat and sparks, and handle it with measures for flammable liquids or gases. The red background with the flame symbol is arranged specifically to warn responders and handlers about fire risk, so you know to take precautions like using proper grounding, avoiding open flames, and storing away from incompatible substances.
