NFPA 704 Hazmat Diamonds

NFPA diamonds are an important tool for identifying chemicals and the issues they might cause. The National Fire Protection Association established their NFPA 704 Diamond Placards to inform rescue workers if particular equipment is required and whether they need to take special precautions. This is why we offer not only pre-set options for NFPA diamonds, but custom diamond creators, kits, and explanation guides. You can even try finding the right diamond by looking for the specific chemical you're dealing with. Have a question or prefer ordering by phone?

Our inventory of 60,000 sign SKUs includes NFPA diamonds, labels, fire diamonds, kits and Explanation Guides. Following NFPA label rules and regulations relating to proper signage is critical in the event of an emergency. During a crisis, fire departments and other emergency crews need the information on the diamond label or sign to determine the appropriate precautions and procedures.

The NFPA’s Role in Fire Diamond Labels and Signs

NFPA-logo-16-17.gifThe mission of the international nonprofit NFPA is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes and standards, research, training, and education. Established in 1896, the organization serves as the world's leading advocate of fire prevention and is an authoritative source on public safety. NFPA's 300 codes and standards influence every building, process, service, design, and installation in the United States, as well as many of those used in other countries. The organization outlines fire diamonds coding. For more information, visit the NFPA at
