Safety data sheets are available for free through manufacturer websites, online databases, and your employer’s workplace system. If you’re searching for “MSDS sheets,” you’re looking for what are now officially called Safety Data Sheets (SDS). OSHA updated the name in 2015 when the U.S. adopted the Globally Harmonized System for classifying chemicals, but the documents serve the same purpose: telling you exactly what’s in a chemical product and how to handle it safely.
Search Engines Are the Fastest Route
The simplest way to find an SDS for any product is a regular Google search. Type the product name, the manufacturer (if you know it), and “SDS” into the search bar. For example: “Simple Green All-Purpose Cleaner SDS” or “WD-40 SDS.” The manufacturer’s PDF will usually appear in the first few results. This works for everything from industrial solvents to household cleaners.
Free Online SDS Databases
Several large repositories collect safety data sheets from thousands of manufacturers in one searchable location. These are especially useful when you don’t know the manufacturer or need to compare products.
- Sigma-Aldrich: One of the largest collections, searchable by product name, CAS number, or product number. Particularly strong for laboratory chemicals.
- Fisher Scientific: Another major scientific supplier with a comprehensive SDS library covering research and industrial chemicals.
- Chemical Safety (chemicalsafety.com): Searchable by product keyword, manufacturer, or CAS number.
- MSDS Digital: A collection of over 130,000 safety data sheets searchable by product name.
- Verisk 3E SDS Search: Searchable by product or manufacturer keyword.
- Consumer Products Information Database: Specifically designed for household products like cleaners, paints, and automotive fluids, pulling safety information directly from product labels and SDS documents.
- National Library of Medicine (TOXNET): Maintained by the NIH, this resource provides toxicology data alongside safety information for chemical substances.
Finding SDS on Manufacturer Websites
Most major chemical and product manufacturers host their own SDS libraries. The search process varies slightly by company. On 3M’s site, for instance, you select “Product Name/Number” from the search dropdown and type in what you’re looking for. Sigma-Aldrich lets you search by product name, CAS number, or catalog number. Virtually every manufacturer that sells chemical products is required to produce an SDS, so even smaller companies typically have them available on their websites or will email one on request.
If a manufacturer’s website doesn’t have an obvious SDS section, look for links labeled “Safety,” “Resources,” “Technical Documents,” or “Product Stewardship.” The document will be a downloadable PDF.
Accessing SDS at Your Workplace
If you work with chemicals on the job, your employer is legally required to make safety data sheets readily accessible during every work shift, in your work area. OSHA’s Hazard Communication Standard is clear on this point: you should not have to ask anyone for an SDS. If accessing the sheet feels like navigating a barrier, that’s a compliance problem.
Many workplaces have shifted from physical binders to electronic SDS systems, and OSHA accepts this. There are three requirements for an electronic system to be compliant. First, the electronic SDS system must be included in the organization’s written Hazard Communication Plan. Second, employees must be able to find and print a hard copy of any SDS if they request one. Third, there must be a backup system in case the electronic system goes down during an emergency.
You don’t need a printed binder at every workstation. But if the power goes out or the network crashes, there needs to be a way to access the information. Some workplaces keep a smaller backup binder with sheets for the most hazardous chemicals on site, while others use offline-capable software or a second access point.
What’s Inside a Safety Data Sheet
Every SDS follows the same standardized 16-section format, which makes them predictable once you’ve read one. The sections most people need are concentrated in the first eight.
Section 1 identifies the chemical and provides the supplier’s contact information, including an emergency phone number. Section 2 tells you the hazard classification: how dangerous it is, what warning symbols apply, and what precautions to take. Section 3 lists the ingredients, their chemical names, CAS numbers, and concentrations.
Section 4 covers first-aid measures for different types of exposure (inhalation, skin contact, eye contact, ingestion) and describes what symptoms to watch for. Section 5 addresses fire-fighting, including which types of extinguishers to use and what toxic fumes the chemical produces when it burns. Section 6 tells you how to handle spills and leaks, from personal precautions to cleanup procedures.
Section 7 gives guidance on safe handling and storage, including which other chemicals it shouldn’t be stored near. Section 8 is where you’ll find the recommended protective equipment: what kind of gloves, goggles, respirator, or ventilation you need.
The remaining sections (9 through 16) cover physical properties like boiling point and flash point, chemical stability, toxicology data, environmental impact, disposal guidance, transportation classification, regulatory status, and other supplementary information. These tend to matter more for safety professionals, but the disposal section (13) is worth checking if you need to get rid of a chemical properly.
MSDS vs. SDS: What Changed
The old Material Safety Data Sheets had no required format. One manufacturer might put first-aid information in section 3, another in section 8. The 2012 revision to OSHA’s Hazard Communication Standard changed that by adopting the GHS format, which locks every safety data sheet into the same 16-section structure. Chemical manufacturers and importers were required to comply by June 2015.
In May 2024, OSHA published another update to keep the U.S. standard aligned with the latest version of GHS. This revision updates the hazard identification, ingredient composition, physical properties, and toxicology sections of the SDS. It also changes how manufacturers can claim ingredient concentrations as trade secrets, requiring them to list prescribed concentration ranges instead of omitting the information entirely. Chemical manufacturers have 18 months from the July 2024 effective date to update sheets for single substances, and 36 months for mixtures. During this transition period, you may encounter SDS documents following either the older or newer format.
If you find an older document still labeled “MSDS,” the safety information in it is generally still valid, but it may be outdated or organized differently. Look for the current SDS version from the same manufacturer to get the most accurate and standardized information.
