What is the shape of an NFPA 704 hazard placard?

Explanation:
NFPA 704 hazard placards are diamond-shaped. The square is rotated 45 degrees, forming a diamond that’s instantly recognizable in emergencies. Inside the diamond, four color-coded sections convey different hazards: blue for health, red for flammability, yellow for reactivity, and white for special hazards. Each section carries a number (0 to 4) indicating the severity, so responders can quickly gauge overall risk at a glance. This distinctive diamond shape helps ensure rapid, consistent identification of chemical hazards across locations.
