GC Labels' Environmentally Hazardous Markings 4x4 labels meet the design and durability standards of 49 CFR, ICAO and other National and International regulations. These labels are required for specific quantities of Organic Peroxide Class 5.2 materials.  All of our Organic Peroxide Class 5.2 hazmat labels are printed with fade resistant pigments and our adhesives are formulated for permanent adhesion in various climates, environments and surfaces. Once affixed, these labels will not come off.

All Environmentally Hazardous Markings are available in either Outdoor grade Vinyl, or Heavy-weight Gloss Paper.

• VINYL -- Environmentally Hazardous Markings labels have a very agressive adhesive.  They have strong adhesion to painted, steel, fiber, plastic and corrugated surfaces.  They are printed on rugged 3.4-mil exterior grade flexible vinyl, and pass the 90-day IMO seawater immersion test.
• PAPER -- Environmentally Hazardous Markings labels have a very agressive adhesive. They have strong adhesion to painted, steel, fiber, plastic and corrugated surfaces. They are printed on heavy-weight gloss paper.  Outdoor life can be limited because they are printed on paper.
