How to Access Material Safety Data Sheets (MSDS)?

Material Safety Data Sheets (MSDS), now known as Safety Data Sheets (SDS), are typically provided by the manufacturer or supplier of a product. Here are a few ways you can access them:

  • Directly from the manufacturer or supplier: Manufacturers and suppliers of hazardous chemicals must provide an MSDS with their products. If you can’t find an MSDS that was supposed to come with a product, contact the manufacturer or supplier directly to ask for it.
  • Manufacturer or supplier website: Many manufacturers and suppliers provide MSDS for their products on their websites. Look for a link to “MSDS,” “Safety Data Sheets,” or “Product Safety” on the company’s website.
  • Online databases: Several online databases collect and provide access to MSDS from various manufacturers and suppliers. These include databases run by private companies, industry associations, and government agencies. Examples include the SIRI MSDS Index, MSDSonline, and the National Library of Medicine’s PubChem database in the United States. While these databases can be useful, they may not always have the most recent version of an MSDS. If possible, always get the most up-to-date information directly from the manufacturer or supplier.
  • In the workplace: Employers must keep a copy of the MSDS for every hazardous chemical used and make them readily accessible to employees. They can be kept in a binder in a central location or stored electronically as long as employees know how to access them and there is a backup system in case of computer or power failures.

Remember, it’s important to ensure that the MSDS you are referring to is the most recent version as manufacturers and suppliers must update their MSDS whenever new significant information about a product’s health, safety, or environmental hazards becomes available.

Material Safety Data Sheet

Historical Background And Evolution Of MSDS

The concept of Material Safety Data Sheets (MSDS), now known as Safety Data Sheets (SDS), traces its roots back to the late 20th century when workplace safety emerged as a significant concern. Here’s a brief look at the history and evolution of MSDS:

  • 1970s – OSHA Formation and the Hazard Communication Standard: In the United States, the Occupational Safety and Health Administration (OSHA) was established in 1970 to ensure workers’ safe and healthy working conditions. One of the regulations OSHA enforced was the Hazard Communication Standard (HCS), originally promulgated in 1983. This standard required chemical manufacturers and importers to evaluate the hazards of the chemicals they produce or import and provide information about them through labels on shipped containers and more detailed information sheets called MSDS.
  • 1994 – Standardization of MSDS: In 1994, OSHA revised the HCS to include a standardized 16-section format for MSDS. This format was voluntary but recommended to help users find pertinent information quickly and easily. It included information such as product and company identification, hazard identification, first-aid measures, fire-fighting measures, accidental release measures, handling and storage, exposure controls/personal protection, physical and chemical properties, stability and reactivity, toxicological information, and ecological information.
  • 2002 – Introduction of the Globally Harmonized System (GHS): 2002 the United Nations adopted the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This system aimed to standardize and harmonize hazard classification and communication globally, including standardizing the format and content of safety data sheets.
  • 2012 – OSHA Adopts GHS: In 2012, OSHA revised its HCS to align with the GHS. As part of this update, “Material Safety Data Sheets” was replaced with “Safety Data Sheets,” and the standardized 16-section format was made mandatory. Adopting the GHS helped ensure that the same set of labels, pictograms, and safety data sheets could be used for hazardous chemicals worldwide, making it easier for workers to understand the hazards, especially for those who work with chemicals from multiple sources.

Over the years, the MSDS (now SDS) has evolved significantly, with a primary goal of improving workplace safety by providing clear, concise, and standardized information on the hazards of chemicals and how to handle them safely.

An MSDS, or Material Safety Data Sheet, is a document that contains information on the potential hazards (health, fire, reactivity and environmental) of a chemical product and how to work safely with the chemical product.

Any workplace where the workers are potentially exposed to hazardous chemicals should have MSDSs available for the employees. This includes places like factories, laboratories, agricultural settings, and many more. It also extends to emergency responders who may encounter the chemicals during their work.

An MSDS typically includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures.

The manufacturer or importer of a chemical product is responsible for creating the MSDS.

It varies by jurisdiction, but generally, MSDS should be reviewed every three to five years or when new information about the chemical becomes available.

MSDS should be stored in an easily accessible location where the employees can access them in case of emergency.

MSDS and SDS essentially serve the same purpose. The difference is that the SDS format is more consistent and universally applicable, as it follows the globally harmonized system (GHS) for classification and labeling of chemicals.

Yes, in many countries, including the United States, Canada, and member states of the European Union, the availability of MSDS for certain types of products is a legal requirement. This is part of the right-to-know laws which mandate that employees have access to information about the chemicals they are exposed to in their workplace.


Please note that while we strive to provide accurate and timely information, laws and regulations regarding MSDS can change. So, it’s always a good idea to consult with a local authority or expert in your area if you have specific questions.


In conclusion, the Material Safety Data Sheet (MSDS) is a fundamental resource in occupational safety. It’s a comprehensive document that provides vital information about the nature of chemicals used in the workplace, their risks, and the precautions necessary for safe handling and use. Beyond its role in everyday operations, the MSDS is instrumental in training employees, preparing for emergencies, and ensuring regulatory compliance.

This guide provides a complete overview of an MSDS, its components, purpose, and use. By understanding and effectively utilizing MSDS, companies can ensure a safer work environment and foster an informed and alert workforce, which is the bedrock of any successful safety program.
