Abstract

A color coded warning label in which the color code has a removable opaque coating and the label is provided with a self-laminating flap for protecting the removable coating prior to use and for making the code permanent during use is described. A method for using the color coded label to quantify the level of a hazard is also described.

Claims

1. A color coded self-laminating warning label for indicating a degree of hazard to a user comprising:

a substrate having first and second ends, and a surface for receiving indicia thereon;

a color code printed on a portion of the surface;

a removable, opaque coating layer overlying the color code;

a sheet of transparent material having a first portion attached to the substrate at the first end and a second portion free from the substrate at the second end;

the second portion of the sheet of transparent material overlying the receiving surface of the substrate, the opaque coating layer and the color code;

a layer of adhesive material on a surface of the sheet of transparent material facing the substrate, the opaque coating layer and the color code; and

a removable protective liner covering the adhesive layer on the second portion of the sheet of transparent material.

2. The label according to claim 1, in which the opaque coating layer comprises a screen ink.

3. The label according to claim 1, in which the color code comprises a segmented colored bar.

4. The label according to claim 3, in which the opaque coating is partly removed to expose a selected number of segments, the selected number of exposed segments indicating the degree of hazard.

5. The label according to claim 3, further comprising a plurality of colored bars in which each colored bar represents a different hazard.

6. The label according to claim 3, in which the colored bar comprises four segments.

7. The label according to claim 1, in which the substrate comprises one of paper and plastic.

8. The label according to claim 7, in which the plastic is a polyester.

9. The label according to claim 1, in which the receiving surface comprises a pencil receiving surface.

10. The label according to claim 1, further comprising:

a layer of adhesive on an opposite surface of the substrate; and

a protective sheet releasably attached to the substrate adhesive layer.

17. The label according to claim 1, in which the surface for receiving indicia comprises a receiving layer coated on the substrate.

11. A color coded self-laminating warning label for indicating a degree of hazard to a user comprising:

a substrate having first and second ends, and a surface for receiving indicia thereon;

a color code printed on a portion of the surface;

a removable, opaque coating layer overlying the color code;

a sheet of transparent material having a first portion attached to the substrate at the first end and a second portion free from the substrate at the second end;

the second portion of the sheet of transparent material overlying the receiving surface of the substrate, the opaque coating layer and the color code;

a layer of adhesive material on a surface of the sheet of transparent material facing the substrate, the opaque coating layer and the color code;

a removable protective liner covering the adhesive layer on the second portion of the sheet of transparent material; and

a mounting hole formed adjacent the first end and passing there through.

12. The label according to claim 11, further comprising a grommet mounted in the mounting hole.

13. A color coded self-laminating warning label comprising:

a substrate having first and second ends, and a surface;

a color code on a portion of the surface;

a removable, opaque coating layer overlying the color code;

a sheet of transparent material attached to one end of the substrate and extending over the removable opaque layer and the color code;

a layer of adhesive material on a surface of the sheet of transparent material facing the substrate, the opaque coating layer and the color code; and

a removable protective liner covering the layer of adhesive material.

14. The label according to claim 13, in which the opaque layer comprises a screen ink.

15. A color coded self-laminating warning label comprising:

a substrate having first and second ends, and a surface;

a color code on a portion of the surface;

a removable, opaque coating layer overlying the color code;

a sheet of transparent material attached to one end of the substrate and extending over the removable opaque layer and the color code;

a layer of adhesive material on a surface of the sheet of transparent material facing the substrate, the opaque coating layer and the color code;

a removable protective liner covering the layer of adhesive material; and

a mounting hole formed adjacent the first end and passing there through.

16. The label according to claim 15, further comprising a grommet mounted in the mounting hole.
