Do you need a UN certification for packaging? When it comes to transporting hazardous materials, certain goods are required to meet UN certification standards to ensure safe handling, storage, and transportation. These standards help to protect people, property, and the environment by minimizing the risks associated with spills, leaks, or exposure. Let’s break down the different categories of hazardous goods and what certification involves.
Categories of Hazardous Materials
The UN’s hazard classification system is widely used for transportation, storage, and handling of hazardous goods globally. According to UN and Department of Transportation regulations, the following are considered hazardous materials:
- Explosives: Substances and articles that can cause an explosion or release gas with extreme heat, pressure, or both. This includes ammunition, fireworks, and blasting agents.
- Gases: Substances that are in a gaseous state at normal temperature and pressure. Gases can be flammable, non-flammable, or toxic. Examples include propane, oxygen, helium, and chlorine.
- Flammable Liquids: Liquids that have a flashpoint below 60°C (140°F) and can easily catch fire. Examples include gasoline, alcohol, acetone, and solvents.
- Flammable Solids: Solid materials that are easily ignited, burn vigorously, or can cause a fire through friction. This includes substances like matches, sulfur, and certain metals.
- Oxidizing Substances: Substances that can cause or contribute to the combustion of other materials by providing oxygen or supporting combustion. Examples include oxygen generators, certain chemicals, and fertilizers.
- Toxic and Infectious Substances: Substances that can cause harm or death when ingested, inhaled, or come into contact with skin. Examples include certain chemicals, pesticides, and infectious substances like viruses or bacteria.
- Radioactive Materials: Substances that emit ionizing radiation above specific limits. This includes nuclear fuels, medical isotopes, and certain industrial radioactive materials.
- Corrosive Substances: Substances that can cause severe damage to living tissues, other materials, or the environment through chemical reaction. Examples include acids, alkalis, and batteries.
- Miscellaneous Dangerous Goods: This class includes materials or substances that don’t fall into the previous eight categories but still present a significant hazard. Examples include lithium batteries, asbestos, and dry ice.
UN Certification Package Testing
The above hazardous goods are crossing borders every day by land, sea, and air. As a result, international law requires a consistent label and marking method that identifies the type and amount of hazardous material. This UN marking procedure ensures a common language across the global shipping industry.
The UN also requires specific packaging to prevent leakage, exposure to external elements, or accidental ignition. These specific packaging requirements depend on the nature of the dangerous goods, such as the type of material, its quantity, and its potential hazards. For example, UN-approved drums are typically used to transport liquid materials. Steel drums are used for corrosive liquids or flammable solvents, while plastic drums may be used for acids or other chemicals that might react with metal.
However, it’s vital to ensure all hazardous goods receive proper labeling and packaging. This is where hazardous goods package testing comes into play. UN certification for packaging hazardous goods requires thorough package integrity testing. These tests assess the compatibility of the hazardous goods with various packaging materials in order to prevent leaks or explosions. They also test whether the packaging can withstand transportation.
These tests typically involve subjecting the materials to different physical conditions, such as temperature, pressure, vibration, or impact, to ensure their integrity and stability. Tests may include:
- Drop tests to evaluate the package’s ability to withstand impacts during handling and transport.
- Vibration tests to simulates the vibrations experienced during transportation.
- Leak-proofness tests that ensure packages containing liquids do not leak under various transport conditions.
- Stack tests subject packages to compressive loads to simulate stacking during storage and transport.
- Hydrostatic pressure tests that check for leakage under pressure.
By meeting these rigorous testing standards, UN-certified packaging not only ensures compliance with international regulations but also safeguards people, property, and the environment during the transportation of hazardous goods.
