Making RTK Warning
Signs & Labels

The NFPA diamond is often used  on RTK warning signsThere are many types of Right-To-Know sign and label designs used to inform employees of chemical hazards. The most popular RTK signs and labels use a number rating and color coding system in conjunction with text to identify the chemical and its physical and health hazards.

The National Fire Protection Association's (NFPA) Standard System for the Identification of the Fire Hazards of Materials is an example of a number and color coding system.

The NFPA Diamond uses color codes to identify Health risks (in blue), Flammability (in red), Instability (in yellow), and Special Hazards (in white). Numbers are used to rate the severity of the hazard on a scale of 0 to 4. 4 represents the most severe. 0 represents minimal or no danger.

For more detailed information about RTK labeling, please see the RTK tutorial or visit the RTK Resource web site.
