Before 2002 the fire diamond and the color bar both had sections colored blue red white and yellow. A value of 0 means that the material poses essentially no hazard whereas a rating of 4 indicates extreme.

The white diamond appearing at the bottom of the label conveys special hazard information. Each of health flammability and reactivity is rated on a scale from 0 no hazard to 4 severe hazard.
