The United Nations provided a Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in order to harmonize and standardize the proper handling and use of chemical management, including its global facilitation. This course provides the background on GHS, its application and implementation, and how hazard classification and communication works.

COMPANIES Safer work environment and improved relations with employees. Increased efficiency and reduced costs from compliance with hazard communication regulations. Application of expert systems resulting in maximizing expert resources and minimizing labor and costs. Facilitation of electronic transmission systems with international scope. Expanded use of training programs on health and safety. Reduced costs due to fewer accidents and illnesses. Improved corporate image and credibility.

Application and Implementation

Globally Harmonized System (GHS) Course - Lesson Excerpt

Application and Implementation of GHS

Application and Implementation

**The GHS is a voluntary international system that imposes no binding treaty obligation on countries. **

**All hazardous chemicals are covered. **

Application and Implementation

The term chemical is used to refer to substances, products, mixtures, preparations, and other terminologies that may be included and used by the current systems.

Application and Implementation

GHS is also compared to a collection of building blocks, due to its classification and communication system on various sectors.

Application and Implementation

The classification and communication structure is designed in a way that makes it easier for its target audience to select and use appropriate elements of the system.

Application and Implementation

GHS Building Block Sectors: Transport Workplace Consumer Pesticides

Hazard Classification

Globally Harmonized System (GHS) Course - Lesson Excerpt

Physical Hazards Explosives Through a chemical reaction, it is capable of producing gas at a certain temperature and pressure with speed causing drastic damage to its surroundings. Flammable Gasses These are gasses with a flammable range in the air at 20°C and a standard pressure of 101.3 kPa. Flammable Aerosoles These are compressed, liquified, or dissolved gasses under pressure contained in a non-refillable metal, glass, or plastic container, with or without liquid, paste, or powder. Oxidizing Gases By adding oxygen, these are gasses that can cause or contribute to the combustion of other materials more than air does. Gases under Pressure These are gases that are contained in a receptacle at a pressure not less than 280 Pa at 20°C or as a refrigerated liquid. Flammable Liquids These are liquids with a flash point of not more than 93°C. Flammable Solids These are solids that are readily combustible, or may cause or contribute to fire through friction. Self-Reactive Substances Even without the participation of oxygen (air), these substances are thermally unstable that they may undergo a strongly exothermic thermal decomposition. Pyrophoric Liquids and Solids After being in contact with air for five minutes, they are liable to ignite even in small quantities. Self-Heating Substances Either solid or liquid(other than pyrophoric substance), by reaction with air and without energy supply, they are liable to self-heat. Substances which on Contact with Water Emit Flammable Gases These are solids or liquids that are liable to spontaneously be flammable or to give off flammable gases in dangerous quantities. Oxidizing Liquids or Solids These are not necessarily combustible, which may yield oxygen, or may cause or contribute to the combustion of other material. Organic Peroxides This contains the bivalent structure (-0-0-) that can be considered a derivative of hydrogen peroxide, where either one or both hydrogen atoms were replaced by organic radicals. Substances Corrosive to Metal Either a substance or mixture that through chemical action will cause damage or destroy metals.

Dilution A diluted mixture with an equivalent or lower toxicity, are considered to have the same hazardous effects.

Hazard Classification

Batching A batch produced through a controlled process is considered to have the same hazardous effects as the original and previous batches.

Hazard Classification

The Concentration of Highly Toxic Mixtures A mixture that is severely hazardous is considered to have the same level of hazard effects as its concentrated mixture.

Hazard Classification

Interpolation within One Toxic Category Mixtures that exhibit a certain component concentration within a range where hazards are known has those certain hazards.

Hazard Classification

Substantially Similar Mixtures Substitutions involving toxicologically similar components and slight changes in the concentration of components are expected not to cause a change in the hazards of the mixture.

Hazard Classification

Aerosols Unless the propellant affects the hazards upon spraying, the tested and the non-aerosolized form of the mixture will have the same hazards.

Hazard Classification

Hazard Communication

Globally Harmonized System (GHS) Course - Lesson Excerpt

In the previous lesson, it was explained that classification is the starting point for the GHS.

Hazard Communication

After classification, communicating the hazard(s) to the people involved or will be involved is the next important step.

Hazard Communication

The main tools for chemical hazard communication are labels and Safety Data Sheets (SDS).

Hazard Communication

These tools identify and provide hazardous properties that may cause health, physical, or environmental hazards during handling and use.

Hazard Communication

Safety Data Sheet (SDS) Identification of the substance or mixture and of the supplier Hazards identification Composition/information on ingredients First aid measures Firefighting measures Accidental release measures Handling and storage Exposure controls/personal protection Physical and chemical properties Stability and reactivity Toxicological information Ecological information Disposal considerations Transport information Regulatory information Other information including information on preparation and revision of the SDS
