GHS hazard pictograms

Small pictures show us danger.

They are on many bottles. Some show things that burn. Some show things that can pop.

These pictures use symbols. They help people stay safe. One picture shows a skull. This means the stuff is very bad to touch or eat.

Other pictures show things that can eat through metal. Some show things that hurt the water and fish.

Labels also use words. They might say "Danger" or "Warning." These words tell us how much risk there is.

We can look at the pictures to learn. They help us handle things the right way.

Small pictures help us stay safe. These are called hazard pictograms. They show if a chemical is dangerous.

There are two main sets of these pictures. One set is for labels on bottles. The other set is for moving goods.

Transport pictures may use more colors. They can also have extra numbers.

Labels use more than just pictures. They name the product. They use a signal word. These words are "Danger" or "Warning." They tell us how much risk there is. Labels also have statements. Some tell us the risks. Others tell us how to handle the product safely.

Many pictures show different risks. An explosive symbol means things might pop.

A flame symbol means things can burn.

A skull and crossbones means a substance is toxic. This means it can be poisonous.

Some pictures show things that hurt the environment.

These symbols help people all over the world. They make sure we know how to be careful.

Hazard pictograms are special symbols used to keep people safe. They are part of a global system called the GHS. This system helps everyone understand chemical risks.

There are two main sets of these symbols. One set is for labels on containers. The other set is for moving dangerous goods.

You do not use both sets for the same hazard. Transport symbols often use more colors. They might also include extra numbers to give more detail.

Labels do more than just show a picture. They include the name of the product. They also use a signal word. These words are either "Danger" or "Warning."

Hazard statements explain the kind of risk a product has. Precautionary statements tell you how to handle things safely. This helps protect users and the environment. The label also lists the supplier. This is the company that made or brought in the product.

Many different symbols show different kinds of physical hazards. An explosive symbol is for things like TNT or nitroglycerin.

A flame symbol shows things that can catch fire easily. This includes flammable gases, liquids, and solids. An oxidizing symbol shows substances that help things burn.

There is also a symbol for compressed gases. This is for things like liquid nitrogen. A corrosive symbol shows substances that can eat through metal.

These symbols help people know exactly what they are handling.

Health hazards also have their own specific symbols. A skull and crossbones means a substance is toxic. This means it can be poisonous if swallowed or breathed in.

A health hazard symbol can show other serious risks. These include things that cause cancer or hurt the lungs. Some symbols show if a substance can damage the eyes or skin.

There is even a symbol for things that hurt the environment.

This is for chemicals that are dangerous to water and animals.

This global system helps replace many different national rules. The European Union began using these rules in 2009. In the United States, rules for transport are very strict. These include the Federal Hazardous Materials Transportation Act. The UN also has rules for moving dangerous goods. These rules help keep trucks and ships safe. By using the same symbols, people everywhere can stay safe. It makes the whole world a bit more organized.

Hazard pictograms are essential visual tools used in the Globally Harmonized System of Classification and Labelling of Chemicals, known as GHS. This international system provides a standardized way to communicate the dangers of chemical substances. By using consistent symbols, the GHS helps people understand risks regardless of what language they speak. The system is divided into two distinct sets of pictograms. One set is designed for labeling chemical containers and providing workplace hazard warnings. The second set is used specifically for the transport of dangerous goods. While both sets use the same core symbols for the same hazards, they are not used together for a single hazard.

When a chemical container is labeled under the GHS, the pictogram is only one part of the safety information. A complete label must also include a clear identification of the product. It requires a signal word, which is either "Danger" or "Warning," to indicate the level of risk. Hazard statements are also included to explain the specific nature and degree of the risks. To help prevent accidents, precautionary statements are added to show how to handle the product safely. This protects the user, other people, and the general environment. Finally, the label must identify the supplier, such as the manufacturer or importer.

Physical hazard pictograms categorize how a substance might react or cause damage. The explosive pictogram (GHS01) is used for substances like TNT or nitroglycerin. The flammable pictogram (GHS02) applies to gases, liquids, and solids that catch fire easily, such as acetone or methanol. Oxidizing substances, shown by the GHS03 symbol, are materials like hydrogen peroxide that can help other things burn. Compressed gases, represented by GHS04, include substances like liquid nitrogen or liquid oxygen. The corrosive pictogram (GHS05) identifies substances that can destroy metal or cause skin and eye damage.

Health hazard pictograms warn of risks to the human body. The toxic pictogram (GHS06), featuring a skull and crossbones, indicates substances that are poisonous through skin contact, swallowing, or inhalation. The health hazard symbol (GHS08) is used for more complex or long-term issues. This includes carcinogenicity, which refers to substances that may cause cancer, or reproductive toxicity. It also covers respiratory sensitization and aspiration hazards. Some symbols, like the exclamation mark (GHS07), are used for skin or eye irritation. However, if a substance is highly corrosive, the corrosion symbol is used instead of the exclamation mark.

Environmental hazards are also addressed through specific symbols. The GHS09 pictogram is used for substances that pose acute or chronic hazards to the aquatic environment. This means the chemicals could be dangerous to water-dwelling life. Transport pictograms follow different rules and often include more color and subcategory numbers. For example, Class 1 transport pictograms identify different types of explosives, such as Division 1.1 for mass explosion hazards. Class 2 covers gases, distinguishing between flammable, non-flammable, and toxic gases. Class 3 is for flammable liquids with a flash point below 60 degrees Celsius.

Other transport classes use specific markers to ensure safety during shipping. Class 4 includes flammable solids and substances that emit flammable gases when they touch water. Class 5 covers oxidizing substances and organic peroxides. Class 6.1 is for toxic substances, which are defined by specific lethal dose or concentration values. Class 8 identifies corrosive substances that can destroy skin tissue or corrode metal surfaces. Some hazards are not part of the GHS but are included in the UN Model Regulations. These include infectious substances, radioactive material, and miscellaneous dangerous goods.

The GHS was created to provide a global basis for hazard symbols, replacing various national systems. For instance, the European Union implemented these rules through the CLP regulation in 2009. In the United States, transport pictograms are used in national regulations like the Federal Hazardous Materials Transportation Act. These rules help manage the movement of goods via the Department of Transportation. By standardizing these symbols, the GHS creates a safer world for workers, travelers, and the environment. It ensures that a warning in one country is understood the same way in another.
