Buying Guide
What to consider when selecting 2.1 flammable gas labels
- Compliance: Ensure the labels meet 49 CFR 172.519 or 172.417 requirements for Division 2.1 and the DOT hazard symbol.
- Format and durability: Choose vinyl for weather resistance or paper for lower-cost, temporary needs. Consider whether permanent or removable labeling is needed.
- Size and visibility: Standard 4×4 inch diamond-format labels are common for ground transport; ensure the size fits the label spaces on vehicles and containers.
- Adhesion: Permanent vs. removable adhesives affect residue and reuse. Test on your surfaces if possible.
- Quantity: For fleets, bulk packs reduce per-unit cost; for occasional labeling, smaller packs or single placards may be more practical.
FAQ
- What is Division 2.1 labeling?
Division 2.1 refers to flammable gases in hazmat shipping, requiring specific wording, class number, and symbols on placards or labels. - Are vinyl labels better than paper for outdoor use?
Yes. Vinyl tends to be water- and weather-resistant, reducing peeling or fading outdoors. - What size should I use for DOT compliance?
4×4 inch labels are standard for many shipments, but check your vehicle or container space to confirm fit. - Can I mix placards and labels from different brands?
Yes, as long as they meet the same DOT requirements and clearly identify Division 2.1 hazards. - Is removable adhesive safer for temporary labeling?
Removable adhesives reduce residue on surfaces but may lift more easily in harsh conditions. - How many labels should a fleet keep in stock?
Stock enough to cover peak shipment periods, plus a small buffer for replacements and re-labeling.
