Packaging can be complicated when it comes to shipping dangerous goods, which are liquids, solids, or gases that can harm people and other living things. Some types of dangerous goods earn the label because they can cause property damage or harm to the environment. Packing and shipping decisions can be made based on the type and class of the substances involved. Here is a look at the nine different classes of dangerous goods.
These are items that can produce heat, light, or smoke in hazardous quantities. Adequate dangerous goods packaging may be necessary when transporting explosives.
Excess oxygen can cause other substances to combust. One class of dangerous goods is dedicated to substances that can yield oxygen and contribute to the combustion of other things.
This class is for substances that may undergo radioactive decay. These materials are potentially harmful because of the radiation they can emit during decay.
Some types of liquids are volatile and can be difficult to transport safely. This class consists of liquids that may release flammable vapor.
There are several types of gases that are dangerous because they can ignite and/or cause asphyxiation. Some examples include aerosols, dissolved gases, refrigerated liquefied gases, and compresses gases.
Gases aren’t the only substances that can be flammable. Combustible solids are substances that can easily catch fire in certain conditions.
These substances can cause severe damage or destruction to property, animals, materials, or people. In most cases, the damage is caused by a chemical reaction.
Toxic and Infectious Substances
Substances in this category may cause harm to people and animals through ingestion or skin contact. Generally, toxic things can be harmful if ingested or swallowed. Infectious substances may contain bacteria, pathogens, or viruses that can cause disease.
Miscellaneous Dangerous Goods
This category covers dangerous materials and substances that don’t fit in other classes. Some may be environmental hazards.
Transporting dangerous goods requires special care and packaging. The classification rules can help transportation personnel decide how to safely move hazardous substances.
