GC Labels' Flammable Gas Class 2.1 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 Flammable Gas Class 2.1 materials.  All of our Flammable Gas Class 2.1 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 Flammable Gas labels are available in either Outdoor grade Vinyl, or Heavy-weight Gloss Paper.

• VINYL -- Flammable Gas 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 -- Flammable Gas 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.
• Flammable Gas Class 2.1 Labels are available in the following styles:

1. Standard Worded labels for Domestic use.
2. Wordless or Blank Labels for Domestic and International use.
