Liquids which have a flash point of less than 60 ☌ and which are capable of sustaining combustion.įlammable Solids, Self-reactive Substances and Solid Desensitized Explosives. Gases which are presumed to be toxic or corrosive to humans because they have an LC50 value equal to or less than 5000 ml/m3 (ppm).Ĭlasses 3 and 4: Flammable Liquids and Solids GHS Hazard. 
Gases which are known to be so toxic or corrosive to humans as to pose a hazard to health. Gases which do not come under the other divisions. Gases which are oxidizing – gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does. Gases which are asphyxiant – gases which dilute or replace the oxygen normally in the atmosphere. have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. are ignitable when in a mixture of 13 per cent or less by volume with air or. Gases which at 20 ☌ and a standard pressure of 101.3 kPa:. Very insensitive substances which have a mass explosion hazard. Substances and articles which are classified as explosives but which present no significant hazard. Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard. Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard. Division 1.1: Substances and articles which have a mass explosion hazard. Chronic hazards to the aquatic environment, categories 1, 2. Acute hazards to the aquatic environment, category 1. Specific Target Organ Toxicity Following Repeated Exposure, Categories 1, 2. Specific Target Organ Toxicity Following Single Exposure, Categories 1, 2. Reproductive toxicity, categories 1A, 1B, 2. Germ Cell Mutagenicity, Categories 1A, 1B, 2. Specific Target Organ Toxicity Following Single Exposure, Category 3. Acute Toxicity (oral, dermal, inhalation), Category 4. Acute Toxicity (oral, dermal, inhalation), Categories 1, 2, 3. Substances and mixtures, which in contact with water, emit flammable gases, categories 1, 2, 3. Self-heating substances and mixtures, categories 1, 2. Self-reactive substances and mixtures, types B, C, D, E, F. Self-reactive Substances and Mixtures, Types A, B. In this sense, the online SDS databases have a clear advantage over binder-based systems since the database vendor usually takes care of indexing and updating the safety data sheets. If the employer does not have an SDS for one of these chemicals they should contact the manufacturer to obtain the current version of the SDS for that chemical. What’s important is that employees have access to the safety data sheets for all of the chemicals that they are using. For example, SDS binders are quite common as are computer-based SDS databases. 
Employers may fulfill this requirement in a variety of ways. SDS Information for EmployersĮmployers must ensure that employees have access to safety data sheets for all of the hazardous chemicals they handle. The last section, section sixteen, contains information about the SDS itself, e.g., the revision date and changes since the last version. Sections twelve through fifteen are not mandatory however, they are required to be fully GHS compliant. Sections nine through eleven contain technical and scientific data, e.g., stability, reactivity, physical & chemical properties. The early sections, one through eight, focus on quick access to essential information that might be required by chemical handlers for safe handling practices or by emergency response personnel. Safety data sheets have sixteen sections.
Provide chemical manufacturers and distributors with a well-defined system to communicate a chemical's hazard information and protective measures.Identify a chemical's health, physical, and environmental hazards.Classify chemical data and hazard criteria.These guidelines were created to ensure the safe manufacturing, handling, use, disposal, and transport of hazardous materials.
GHS is a set of international guidelines that were developed by the United Nations. SDS's typically contain chemical properties, health and environmental hazards, protective measures, as well as safety precautions for storing, handling, and transporting chemicals. The International Hazard Communication Standard (HCS) mandates that chemical manufacturers must communicate a chemical’s hazard information to chemical handlers by providing a Safety Data Sheet. A safety data sheet, or SDS, is a standardized document that contains occupational safety and health data.
