The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally agreed-upon standard managed by the United Nations that was set up to replace the assortment of hazardous material classification and labelling schemes previously used around the world. Core elements of the GHS include standardized hazard testing criteria, universal warning pictograms, and safety data sheets which provide users of dangerous goods relevant information with consistent organization. The system acts as a complement to the UN numbered system of regulated hazardous material transport. Implementation is managed through the UN Secretariat. Although adoption has taken time, as of 2017, the system has been enacted to significant extents in most major countries of the world. This includes the European Union, which has implemented the United Nations' GHS into EU law as the CLP Regulation, and United States Occupational Safety and Health Administration standards.

👉 Globally Harmonized System of Classification and Labelling of Chemicals in the context of GHS hazard pictograms
Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods. Either one or the other is chosen, depending on the target audience, but the two are not used together for the same hazard. The two sets of pictograms use the same symbols for the same hazards, although certain symbols are not required for transport pictograms. Transport pictograms come in a wider variety of colors and may contain additional information such as a subcategory number.
Hazard pictograms are one of the key elements for the labelling of containers under the GHS, along with:

Globally Harmonized System of Classification and Labelling of Chemicals in the context of Environmental hazard
There are two widely used meanings for environmental hazards; one is that they are hazards to the natural environment (biomes or ecosystems), and the other is hazards of an environment that are normally present in the specific environment and are dangerous to people present in that environment.
Well known examples of hazards to the environment include potential oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, and build-up of atmospheric carbon dioxide. They may apply to a particular part of the environment (slash and burn deforestation) or to the environment as a whole (carbon dioxide buildup in the atmosphere)..
Globally Harmonized System of Classification and Labelling of Chemicals in the context of Toxic substances
In science, poison is one of the chemical substances that is harmful or lethal to a living organism. The term of poison is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense.
The symptoms and effects of poisoning in humans can mimic those of other medical conditions and vary depending on the type of poison and the system of the body affected. Common symptoms include alterations in consciousness, abnormal body temperature, irregular heart rate, and changes in respiration. The severity and specific presentation of symptoms often depend on the nature and dose of the poison involved.
Globally Harmonized System of Classification and Labelling of Chemicals in the context of Dangerous goods
Dangerous goods are substances that are a risk to health, safety, property or the environment during transport. Certain dangerous goods that pose risks even when not being transported are known as hazardous materials (syllabically abbreviated as HAZMAT or hazmat). An example of dangerous goods is hazardous waste which is waste that threatens public health or the environment.
Hazardous materials are often subject to chemical regulations. Hazmat teams are personnel specially trained to handle dangerous goods, which include materials that are radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating, biohazardous, toxic, poisonous, pathogenic, or allergenic. Also included are physical conditions such as compressed gases and liquids or hot materials, including all goods containing such materials or chemicals, or may have other characteristics that render them hazardous in specific circumstances.
Globally Harmonized System of Classification and Labelling of Chemicals in the context of Flammable liquid
A flammable liquid is a liquid which can be easily ignited in air at ambient temperatures, i.e. it has a flash point at or below nominal threshold temperatures defined by a number of national and international standards organisations.
The Occupational Safety and Health Administration (OSHA) of the United States Department of Labor defines a liquid as flammable if it has a flash point at or below 93 °C (199.4 °F). Prior to bringing regulations in line with the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in 2012, OSHA considered flammable liquids to be those with a flash point below 37.8 °C (100.0 °F). Those with flash points above 37.8 °C/100 °F and below 93.3 °C (199.9 °F) were classified as combustible liquids. Studies show that the actual measure of a liquid's flammability, its flash point, is dependent on the local air pressure, meaning that at higher altitudes where the air pressure is lower, the flash point is also lower.
