An SDS library helps bring everything together in one place. It gives your team a reliable way to find, manage, and access Safety Data Sheets whenever they are needed. Whether you're preparing for an inspection, responding to a workplace incident, or introducing a new substance on site, having an organised SDS library makes the process faster, easier, and more compliant.
This article explains how to build an SDS library from scratch, what information it should contain, and how to keep it accurate over time. We’ll also look at practical ways to create and maintain a digital SDS library at no cost, including how ISDSS can provide a free starting point.
Why Your Business Needs an SDS Library
Under COSHH regulations, employers are responsible for identifying every hazardous substance used in the workplace and having the relevant Safety Data Sheet available to the people who work with it. That last part matters. Having a document on a manager's hard drive is not the same as having it accessible.
Businesses that manage this well share a few things in common. They know exactly which substances are on site. They have the current SDS for each one. And the people who need them know where to find them. Getting there does not require expensive software. It requires a system.
Step 1: Take Stock of What You Use
Before you can build a library, you need to know what goes in it. Walk through your site and make a list of every product or chemical your team works with. This means:
- Cleaning products and detergents
- Paints, adhesives, solvents and coatings
- Fuels and lubricants
- Laboratory or process chemicals
- Substances brought in by contractors
- Products left by previous tenants or suppliers
Do this physically rather than from memory. Substances accumulate in cupboards, maintenance stores and areas that are easy to overlook. The only reliable way to get a complete list is to look.
Step 2: Obtain the Current SDS for Each Substance
Once you have your list, there are two main ways to get the documents:
From the manufacturer or supplier
Under UK REACH, manufacturers and suppliers are legally required to provide an SDS for any hazardous substance. If you do not have one, request it. They must provide it. The HSE guidance on Safety Data Sheets sets out what a compliant document needs to contain.
From an SDS database
Contacting each manufacturer individually is slow. An online SDS database gives you access to documents from thousands of manufacturers in one place. ISDSS provides free access to over 1.5 million Safety Data Sheets, searchable by product name or manufacturer. You can find and download documents without going back to suppliers.
Step 3: Organise Your Library
There is no single right way to organise an SDS library. What matters is that people can find what they need quickly. A few approaches work well depending on the size of your operation:
◉ By location or area of use
Useful for multi-area sites where different teams work with different substances. A cleaning team does not need to search through engineering documents, and vice versa.
◉ Alphabetically by product name
Simple and consistent. Works well for smaller libraries or when substances are used across the whole site.
◉ By hazard category
Grouping by GHS hazard type (flammables, corrosives, irritants) helps workers find information about substances with similar properties and compare precautions.
Whichever structure you choose, a simple index spreadsheet is worth maintaining alongside it. A spreadsheet with product name, manufacturer, SDS location and revision date gives you a searchable catalog and makes it easy to spot when a document is due for a check.
ISDSS has an 'Add to My Library' feature that saves SDS documents to your personal account. If you are building a digital library, this is a useful way to organise the substances you use most without maintaining a separate folder structure.
Step 4: Keep It Current
An SDS library that has not been reviewed in a year is a liability, not an asset. Manufacturers revise documents regularly as hazard classifications change and new data becomes available. An SDS that was accurate two years ago may carry different signal words, H-phrases or PPE requirements today.
A few habits that help:
- Check for updated SDS when you renew supplier contracts or change product brands
- Review the full library annually as part of your COSHH assessment
- When you search ISDSS, the revision date appears on each product page, so you can check whether the version you hold is still current
- When you replace a document, note the date and keep a record of what changed
A printed binder of SDS documents that has never been reviewed is not a library. It is a record of what the hazards were at some point in the past.
Step 5: Make Sure Workers Know How to Use It
The best SDS library is useless if the people who need it cannot find what they are looking for. This is worth a short session during induction and occasional reminders. Workers should know where the library is stored, how to search for a product by name, and what sections of the SDS are most relevant in different situations. The ISDSS Safety Training page has further resources if you want to build this into a broader safety programme.
For physical libraries, make the location visible and known. A folder in the office that nobody on the shop floor knows about does not count as accessible. For digital libraries, a QR code posted near chemical storage areas linking directly to the SDS search is a practical shortcut that costs nothing to set up.
⚠️ Common Mistakes to Avoid
- Only keeping SDS for substances you purchased. Substances brought in by contractors or left by previous occupants are still your responsibility if they are on your site.
- Using the SDS as the risk assessment. The SDS gives you the hazard information needed for a COSHH assessment. It is not the assessment itself. The two serve different purposes.
- Printing and forgetting. A binder of documents that nobody maintains is not compliance. It is a paper trail that will work against you in an inspection.
- Keeping only one copy. If your SDS library lives on one person's computer, what happens when they are off sick?
- Not checking revision dates. SDS documents are updated more often than most businesses expect. A classification that was current last year may have changed.
