Understanding the 9 Classes of Dangerous Goods

The term “dangerous goods” is used to describe substances that pose risks to the safety of people and the community. They’re divided into 9 classes, which are listed in this article. Read on to learn some examples under each category.

1 – Explosives

Substances that can cause even a tiny explosion are categorized under Class 1. They can be solid, liquid, or gas that can spark or detonate after a slight chemical reaction. Some examples include pyrotechnic devices, fireworks, and gunpowder.

2 – Gases

Class 2 covers all types of gases, including natural, compressed, dissolved, and liquefied ones. They’re usually loaded into small and air-tight metal tanks that are carefully placed in crates or larger containers. Some of them may cause an explosion, while others may be poisonous when inhaled.

3 – Flammable Liquids

Under Class 3 are liquid substances that can ignite when exposed to a temperature of 140 degrees F. They include gasoline, petroleum, ethanol, methanol, and large quantities of acetone, perfume, and paint. Usually, they’re loaded into air-tight trucks and tanks.

4 – Flammable Solids

Class 4 is comprised of solid substances that may cause spontaneous combustion or release flammable gases upon contact with water. Some examples include alkali metals and powdered chemicals, like sulfur and phosphorous.

5 – Oxidizing Substances and Organic Peroxides

Substances in this category can release huge quantities of oxygen, which is a highly flammable gas. They also include materials that can cause dangerous chemical reactions and damage a person’s eyes. Hydrogen peroxide and ammonium nitrate fertilizers are just a few examples.

6 – Toxic or Infectious Substances

Class 6 covers goods that can endange a person’s health due to exposure to poison or live bacteria. These include clinical wastes, pesticides, and lead compounds.

7 – Radioactive Materials

Radioactive materials contain unstable atoms that can cause problems with a person’s health and the environment. They include products with a high amount of uranium and some types of industrial wastes and medical substances. Since they’re quite hazardous, they’re loaded into air-tight containers with a clear label before they’re transported.

8 – Corrosives

Substances that induce corrosion, such as battery fluids and other types of acids, are under Class 8. They’re extremely dangerous since they can cause rapid decay of metals and plastic. Also, they can result in irritation when they touch the skin.

9 – Miscellaneous

This covers anything that doesn’t fall under the other 8 classes. Asbestos, some genetically modified organisms (GMOs), and even sharp devices, like chainsaws and knives, fall under this broad category.

Although they’re dangerous, most of them are still needed for the business operations of some companies. These firms often rent orpurchase a modular building in NYC for the delivery and receipt of the hazardous materials they need.
