Dangerous Goods and Their Hazard Classes with Examples

Posted On 4th September 2023

In a world brimming with innovation and progress, the production and transportation of various goods have become indispensable. However, the advancement of industry and commerce has brought along with it a concerning facet: hazardous materials.

These materials, often referred to as dangerous goods, necessitate stringent handling, transport, and safety regulations due to their potential to harm human health, the environment, and property.

In this article, we will delve into the world of hazmat classes and explore some examples of dangerous goods that fall within these categories.

What are Hazardous Materials

Hazardous MaterialsDefining Hazardous materials is important, especially in the United States, because there are laws that dictate how you handle and ship hazardous materials.

Breaking one of those laws, even unknowingly, may result in harm to employees and heavy fines and penalties.

Hazardous materials, commonly known as hazmat, encompass a broad spectrum of substances that possess the potential to cause harm.

This harm can be in the form of physical damage, health hazards, or environmental degradation.

Due to their inherent dangers, hazardous materials require careful handling, storage, and transportation to mitigate potential risks.

What Are the 9 Classes of Dangerous Goods

To effectively manage and regulate the transportation of hazardous materials, they are categorized into nine distinct classes based on their predominant properties. These classes provide a comprehensive framework for understanding and dealing with dangerous goods. The nine classes are as follows:

Class 1 - Explosives:

Substances or articles that can rapidly release energy in the form of heat, light, sound, or gas. Mass explosion hazard examples include fireworks and dynamite.

Class 2 - Gases:

Class 2 gases are gaseous substances that can become hazardous when exposed to specific conditions, such as pressure or temperature. This class is divided into three divisions based on the type of hazard posed: flammable gases, non-flammable gases, and toxic gases.

Class 3 - Flammable Liquids:

Liquids with a low flash point that can easily ignite under certain conditions. Gasoline and alcohol are examples of flammable liquids.

Class 4 - Flammable Solids:

Solid materials that can ignite and burn when exposed to a flame or heat source. Examples include matches, certain chemicals, and solid-desensitized explosives

Class 5 - Oxidizing Substances and Organic Peroxides:

Class 5 oxidizing substances and organic peroxides are substances that can release oxygen and intensify the combustion of other materials. Hydrogen peroxide is an example of an organic peroxide.

Class 6 - Toxic and Infectious Substances:

Class 6 toxic substances can cause severe harm to human health when exposed. This class is divided into two divisions: toxic substances and infectious substances.

Class 7 - Radioactive Materials:

Materials that emit ionizing radiation. These materials are commonly used in medical, industrial, and research applications.

Class 8 - Corrosive Substances:

Corrosives are chemical substances that can cause severe damage to living tissue or other materials upon contact. Battery acid and hydrochloric acid fall into this category.

Class 9 - Miscellaneous Dangerous Substances and Articles:

Class 9 miscellaneous materials don't fit into the previous eight classes but still pose risks during transportation. This class includes environmentally hazardous substances and substances with specific hazards not covered elsewhere.

Common Hazards and Their Classes

Here is a list of some common hazards and their chemical hazard classes. Knowing the different classes of hazardous materials will help you stay safe when dealing with them.

  1. Sulfuric Acid Hazard Class - Class 8: Corrosive
  2. Organic Peroxide Hazard Class - Class 5: Oxidizing Chemicals
  3. Nitric Acid Hazard Class - Class 8: Corrosive
  4. Plutonium Hazard Class - Class 7: Radioactive Materials
  5. Helium Hazard Class - Class 2: Gases
  6. Mercury Hazard Class - Class 8: Corrosive
  7. Hydrochloric Acid Hazard Class - Class 8: Corrosive

Toilet Bowl Cleaner is an Example of Which Hazard Class

Toilet bowl cleaner is a common household item. Most people have it on hand, but did you know it’s actually a hazardous material? But exactly what hazard class is toilet bowl cleaner?

Toilet bowl cleaner is typically classified as a hazardous material due to its corrosive nature. The toilet bowl cleaner hazard class is important to know because it will help you better know how to handle the substance and what threats it poses. So toilet bowl cleaner is what hazard class? The answer is class 8.

Corrosive substances, categorized under Class 8, have the potential to cause significant damage to living tissue and materials they come into contact with. Toilet bowl cleaner falls into this category because of its ability to remove stubborn stains and mineral deposits through a corrosive chemical reaction. It's essential to handle such substances with care, using appropriate protective gear and following recommended safety protocols

Toilet bowl cleaner is which hazard class? - Class 8

What are the Types of Chemical Hazards

Chemical hazards fall into two categories: health hazards and physical hazards. Most chemicals are classified as health hazards. Health hazards encompass the potential risks posed to human health, such as toxicity, carcinogenicity, and skin sensitization. Physical hazards, on the other hand, refer to dangers that can result from a substance's physical properties, including flammability, reactivity, and explosiveness.

What is the Hazard Statement for Skin Sensitization

Skin sensitization is an example of a health hazard. Hazard statements are standardized codes used to communicate specific hazards associated with chemicals. The hazard statement for skin sensitization is "May cause an allergic skin reaction." This indicates that exposure to the substance can result in an allergic response upon contact with the skin.

Skin sensitization is an example of what hazard class? - GHS Category 1

What Kind of Hazard is Acid: Sulfuric, Nitric, Hydrochloric

Acids such as sulfuric acid, nitric acid, and hydrochloric acid fall under the corrosive substance category, which is a type of health hazard. These acids have the potential to cause severe damage to living tissue and materials upon contact. Additionally, they can react with other substances in a way that releases harmful gases, further increasing their danger.

Some Exotic Hazardous Materials - Plutonium, Helium, Mercury

While many hazardous materials are commonly encountered in industrial and domestic settings, some exotic examples also deserve attention.

Plutonium, a radioactive material used in nuclear reactors and weapons, poses significant risks due to its ionizing radiation.

Helium, while not typically considered hazardous, can pose risks when stored under high pressure due to its potential to cause containers to rupture.

Mercury, a heavy metal with toxic properties, is hazardous due to its ability to accumulate in organisms and cause harm to both human health and the environment.
