Why Labeling and Marking Are So Important
Transporting hazardous goods comes with risks. If a package is not marked correctly, handlers may not know how to store, move, or react to it. In a worst-case scenario, a mislabel could cause spills, fires, or toxic leaks. Labels and marks tell workers what they are handling. They also ensure that goods meet international transport laws.
Each package must have clear, durable labels that stay visible throughout shipping. Marks give extra details, such as handling instructions or UN identification numbers. Together, these markings help prevent serious accidents.
Regulations That Set the Standards
Several agencies have strict rules on packaging for hazardous materials and how they must be labeled. These include:
- Department of Transportation (DOT) – Governs transport within the U.S.
- International Air Transport Association (IATA) – Covers air shipments worldwide.
- International Maritime Dangerous Goods (IMDG) Code – Applies to sea transport.
- United Nations (UN) Recommendations – Sets global guidelines.
Each organization requires labels to meet size, color, and material standards. Some must be waterproof or resistant to fading. The type of hazard determines the required labels and marks.
Required Labels for Hazardous Shipments
Labels warn about the type of danger a package holds. These come in bright colors and specific symbols, so they are easy to spot. Some of the most common hazard labels include:
- Flammable Liquids (Class 3) – Red labels with a flame symbol.
- Corrosive Substances (Class 8) – Black and white labels showing a chemical eating through metal.
- Toxic and Infectious Substances (Class 6.1 & 6.2) – Skull and crossbones for poisons, or biohazard symbols for infections.
- Explosives (Class 1) – Orange labels with a bursting bomb symbol.
- Gases (Class 2) – Symbols vary for flammable, non-flammable, and toxic gases.
Each label must be at least 100 mm x 100 mm (4 x 4 inches) and placed on the correct side of the package.
Key Markings That Can’t Be Missed
In addition to hazard labels, packages need clear markings. These include:
- UN Number – A four-digit code that identifies the exact substance.
- Proper Shipping Name – The official name of the material.
- Packing Group (PG) – Indicates the level of risk (I = high, II = medium, III = low).
- Orientation Arrows – Used for liquids to show the correct upright position.
- Handling Instructions – Words like "Keep Away from Heat" or "Use No Hooks" to prevent damage.
Special Rules for Air Transport
Air transport has extra restrictions due to pressure changes and cargo handling risks. Labels must be strong enough to handle extreme conditions. Some airlines require extra markings to follow their safety rules.
For example, if using shipping air bags for protection, labels must still be visible. Any extra layers of packaging should not block markings. Air shipments also require a Shipper’s Declaration, listing all hazards.
Common Mistakes and How to Avoid Them
Even small mistakes can cause big problems. Some common errors include:
- Wrong Label Placement – Labels must be on the correct side and not covered by tape.
- Using the Wrong Label – Some materials have similar risks but require different labels.
- Faded or Damaged Labels – Must be waterproof and resistant to smudging.
- Missing UN Number – This code is vital for emergency responders.
To avoid these mistakes, companies should train workers and use high-quality materials for printing labels.
The Cost of Non-Compliance
Breaking labeling laws can lead to serious penalties. Fines range from a few hundred to thousands of dollars per violation. If an accident happens due to mislabeling, companies could face lawsuits. In extreme cases, businesses may be banned from shipping hazardous goods.
Regulatory agencies conduct inspections and issue warnings. Repeat offenses often result in higher fines. Companies can stay compliant by following up-to-date laws and conducting regular checks on packaging.
Improving Safety and Compliance
The right labels and marks are essential for safety. Businesses shipping hazardous materials should:
- Train workers on the latest rules.
- Use high-quality labels that won’t fade or peel.
- Regularly review packaging requirements.
- Keep records of shipments and labeling methods.
Clear, correct labeling not only prevents accidents but also ensures smooth shipping. When done right, it protects workers, cargo, and the environment.
