Easy-to-Use Custom NFPA 704 Diamond Generators and Resources

Chemical / Hazmat / Pipeline

The National Fire Protection Agency (NFPA), in section 704 of the National Fire Code, specifies a system for identifying hazards associated with various materials. Proper identification of hazards is essential for emergency responders and anyone who needs to handle such materials. People who need NFPA 704 diamonds love our custom NFPA sign generators that let them create and preview custom NFPA diamonds with just five clicks.

These NFPA 704 sign tools include a rating explanation guide and a link to the NFPA 704 standard to help users choose the correct hazard level. On the preview page, one more click lets users select materials from 1-inch vinyl labels to 30-inch aluminum signs.

And if you need custom NFPA 704 diamonds with chemical text, we’ve made that easy, too.
A second NFPA tool lets you:

  • Select 3 Rating Numbers and a Symbol for your diamond from dropdown menus
  • Enter your custom text and CAS# – format the text to meet your needs
  • Click the Proceed – Select Size + Material button for product details, options and pricing

Please refer to NFPA Standard 704 Section 4.3, Location of Signs, for specifics on where to post NFPA 704 placards.

Notes On Special Hazard Symbols

Although NFPA diamonds commonly are created with a variety of symbols, only three symbols are authorized by the NFPA for use on Hazmat Diamonds: OX, SA and W.

Authorized Special Hazard Symbols:

  1. OX – Oxidizer
  2. SA – Asphyxiant
  3. W – No Water

Non-authorized Symbols Commonly Used:**

  • ACID – Acid
  • ALK – Alkaline
  • COR – Corrosive
  • COR+OX – Corrosive Oxidizer
  • COR+OXY – Corrosive Oxidizer
  • CRY – Cryogenic
  • OXY – Oxidizer Agent
  • W + OX – No Water Oxidizer
  • RAD – Radioactive

**Emergency responders in your area might not recognize non-authorized symbols used on NFPA Diamond signs, because they are not defined in NFPA 704. Before using these symbols, consult your local emergency response team regarding size and placement of non-authorized symbols with your NFPA diamond.
