Dangerous goods are substances that pose a risk to health, safety, property, or the environment. The transportation of these goods has become an essential part of various industries like chemicals, explosives, or biological agents. So, in order to ensure public safety, the safe and compliant shipment of these materials is more than important.

One of the crucial parts of this process is the proper marking and labeling of dangerous goods. It plays a vital role in communicating the necessary information like handlers, transporters, and the nature of the contents within a package. They provide critical information regarding hazards, handling precautions, and emergency response measures.

Hence, it is a moral obligation for businesses engaged in the process to ensure compliance with international and national regulations, otherwise it can lead to severe consequences such as accidents, injuries, environmental damage, or death. Also, companies may face negative publicity or loss of business for failing to meet safety standards.

Considering the same, the following sections of the blog will guide you through the essential aspects of marking and labeling dangerous goods shipments.

What are Dangerous Goods?

Dangerous goods are classified into 9 classes based on their inherent properties and the risks they pose. These categories are established by global regulatory bodies like the UN (United Nations) and IATA (International Air Transport Association).

The classification of dangerous goods is crucial for their safe handling and transport. Each class has specific requirements regarding packaging, labeling, and documentation to prevent accidents and ensure that those handling or transporting these goods are aware of the risks.

Regulatory Framework

The regulatory framework for the marking and labeling of dangerous goods includes a variety of laws, guidelines, and standards that clearly define how dangerous goods should be identified, handled, and communicated to all parties involved in the shipping process.

Here are the key regulatory bodies involved in the process of setting and ensuring regulatory framework:

1. International Regulations: The transport of dangerous goods is regulated by several international bodies such as the United Nations (UN) has established specific guidelines for marking and labeling. While the IATA provides regulations specific to air transport, the International Maritime Dangerous Goods (IMDG) Code governs sea transport.

Also, ADR guidelines cover the road transport of dangerous goods in Europe and the Globally Harmonized System (GHS) provides a consistent classification system for chemicals and dangerous goods across all modes of transport.

2. National Regulations: In the United States, while OSHA regulates workplace safety and sets standards for the handling of hazardous materials during shipping and transport, the DOT oversees the transportation of dangerous goods within the U.S. under the Hazardous Materials Regulations (HMR).

3. Compliance Standards: The International Organization for Standardization (ISO) provides standards that may affect the marking and labeling of dangerous goods. Alongside this, enforcement agencies, such as the Environmental Protection Agency (EPA) and the Department of Transportation (DOT), regularly inspect shipments to ensure compliance.

Key Components of Dangerous Goods Marking and Labeling

Marking and labeling provide critical information to ensure safety, proper handling, and compliance with regulations. Here are the key components involved:

Marking: 

• Proper Shipping Name is the official name of the hazardous material, which must be clearly stated on the package. It provides information about the contents and their potential hazards.
• Every dangerous good is assigned a unique UN Number (United Nations Number) that identifies the substance or material. This number is crucial for first responders, customs, and shipping personnel to identify the goods quickly in case of an emergency. For example, UN 1203 is used for gasoline.
• The full name and address of both the shipper and the recipient must be marked on the package to ensure correct delivery and facilitate communication in case of emergencies.
• Depending on the regulations, packages may need to indicate either the net quantity of dangerous goods or the gross weight if multiple packages are involved.
• If a dangerous substance is a mixture, the technical name may be required for clarity.
• It is important to include the classes or categories of dangerous goods being shipped. For example: Class 3 for flammable liquids, Class 2 for gases, and Class 8 for corrosive substances.

Labeling

• Hazard Labels that tell about the primary hazards associated with the dangerous goods must be displayed in a diamond shape at an angle of 45 degrees, in specific colors and symbols to indicate different types of hazards. For example: flammable, toxic.
• Additional labels may be required to provide instructions on how to handle or store the materials safely. This includes warnings about specific risks associated with the goods. For example: “Keep Away from Heat” or “Fragile” to help personnel take proper care.
• For certain substances classified as environmentally hazardous (e.g., UN 3077 or UN 3082), Environmental Hazard labels depicting a “dead fish” symbol must be affixed to alert handlers to potential ecological risks.

Placement and Visibility

• All labels and markings should be placed on one side of the package. If there is insufficient space for all required labels, a larger package should be used.
• It is crucial that all markings and labels are clearly visible. This includes ensuring that printed information is not covered by any other materials or packaging elements like tape, text, etc.

Best Practices for Marking and Labeling Dangerous Goods

In addition to the set standards & regulations, discussed below are some points that can help you ensure proper marking & labeling of dangerous goods.

• All markings and labels must be durable, legible, and printed in English (or other languages as required). They should withstand environmental conditions (e.g., rain, UV light) to avoid fading or damage during transit.
• Prepare any necessary documentation, such as a shipper’s declaration for dangerous goods if required by regulations. This document should accompany the shipment to provide additional information about its contents.
• Before shipping, conduct a thorough check to ensure all markings and labels comply with regulatory requirements. 
• Ensure that labels are positioned correctly according to the regulations for each mode of transport (air, sea, road) and the type of container. For instance, hazardous labels should be on opposite sides of the package to ensure visibility from all angles.

Common Mistakes and How to Avoid Them

To ensure the safe transport of dangerous goods, meticulous attention to marking & labeling solutions are required. However, there are some common and minor mistakes that can compromise safety and fail to ensure compliance:

• Regulations and standards for hazardous materials evolve over time. Regularly update labels and markings to ensure compliance and stay informed about changes in regulations.
• Personnel lacking proper training may mislabel or mishandle dangerous goods. Provide comprehensive training on current regulations and correct labeling practices. 
• When transporting multiple hazardous materials together, each must be accurately labeled. Ensure that all applicable hazard labels are present and the guidelines are followed to prevent adverse reactions. 
• Different transportation modes (air, sea, road) have varying regulations, and failing to account for these differences can lead to non-compliance. For this, familiarize yourself with the specific requirements for each mode of transport.

Summing Up

Transportation of dangerous goods safely is very important. In addition to following the above measures, conduct regular audits to confirm that all shipments meet marking & labeling standards. Keep yourself updated about changing regulations and invest in ongoing training for your team. 

It is also important to raise awareness about the risks of incorrect labeling and ensure everyone knows emergency procedures. By prioritizing these practices, we can help prevent accidents and protect everyone involved.
