Do safety data sheets expire?

Not by law in a fixed number of years. Neither OSHA nor REACH sets a calendar expiry date for an SDS. However, suppliers must revise an SDS when significant new hazard information appears (within three months under OSHA; without delay under REACH), so an SDS can become outdated at any time. That is why labs set their own review interval and treat an SDS past that interval as “expired” until it has been checked.

How often should a lab check for updated SDSs?

There is no single legal interval. Many institutions choose a fixed cycle such as every one to three years, with shorter cycles for highly hazardous substances, and also check whenever a chemical is reordered. In Labcup, the host administrator sets this interval once for the whole site.

Is electronic SDS access allowed, or do we need paper binders?

Electronic access is allowed. OSHA permits electronic access and other alternatives to paper as long as they create no barrier to immediate employee access in each workplace. REACH allows SDSs to be supplied on paper or electronically. Plan a fallback, such as offline copies or a QR code on the label, for power or network outages.

How long should old SDSs be kept?

Keep them. REACH requires downstream users to keep the information they need for compliance for at least 10 years after they last used a substance (Article 36). Archiving every superseded version, rather than deleting it, also lets you show which hazard information applied on a given date.

Who is responsible for keeping SDSs current?

The supplier is responsible for writing and revising the SDS. The employer, meaning the lab or institution, is responsible for holding a current SDS for every hazardous chemical it uses and making it accessible. Software can flag gaps and offer newer versions, but a person should review and approve each update.

What is the difference between an SDS and an MSDS?

An MSDS (material safety data sheet) was the older format, which varied in layout. The SDS is the GHS-aligned replacement with 16 sections in a fixed order. In the US, the switch came with OSHA’s 2012 revision of the Hazard Communication Standard.

What should a lab do with chemicals that came without an SDS?

Under OSHA, if a hazardous chemical arrives without an SDS, the employer must obtain one from the manufacturer or importer as soon as possible. In an inventory-linked system, a “Missing SDS” filter makes these chemicals visible immediately.

SDS Management in Labs: Why It Matters and How to Link Safety Data Sheets to Your Chemical Inventory

What the law requires, where labs usually go wrong, a 7-step setup, and how keeping every SDS on the chemical’s inventory record makes compliance a by-product of daily work.

Quick answer

SDS management is the process of keeping a current safety data sheet (SDS) for every hazardous chemical in your lab, making it instantly accessible to the people who handle that chemical, and tracking when it needs to be replaced. Regulators such as OSHA in the US and REACH in the EU require it. The most reliable and least labour-intensive way to do it is to attach each SDS directly to the chemical’s record in your chemical inventory, so that every container, location and user is automatically linked to the right safety information.

OSHA requires employers to keep an SDS for each hazardous chemical in the workplace and to keep it readily accessible to employees during every work shift (29 CFR 1910.1200(g)(8)).
Electronic SDS access is explicitly permitted, provided it creates no barrier to immediate employee access.
Under OSHA, SDS authors must add significant new hazard information to the SDS within three months of becoming aware of it, so SDSs do change over time.
Under the 2024 update of the OSHA Hazard Communication Standard, employers must update workplace labels, the hazard communication program and training for newly classified substance hazards by November 20, 2026, and for mixtures by May 19, 2028.
An SDS stored in a binder or shared drive is disconnected from what is actually on your shelves. An SDS linked to the inventory record shows you, in one search, which chemicals have no SDS, which SDSs are outdated, and where every hazardous container is located.

What is a safety data sheet (SDS)?

A safety data sheet (SDS) is a standardized document, written by the chemical’s manufacturer, importer or supplier, that describes a chemical’s hazards and how to handle, store, transport, dispose of and respond to it safely. SDSs replaced the older Material Safety Data Sheets (MSDS) when regulators aligned with the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

Every GHS-aligned SDS has the same 16 sections in the same order:

Identification
Hazard(s) identification
Composition / ingredients
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
Ecological information
Disposal considerations
Transport information
Regulatory information
Other information, incl. date of last revision

Section 16 matters for management: it carries the date of preparation or last revision, which is how you tell whether the SDS you hold is the current one.

What is SDS management?

SDS management is the ongoing process of making sure that, for every hazardous chemical on site, the lab:

Has an SDS (no chemical without one).
Holds the current version, in the right language and for the right region.
Makes it immediately accessible to everyone who works with or near the chemical, including emergency responders.
Reviews it periodically and replaces it when the supplier issues a new version.
Keeps an archive of earlier versions as a historical record.
Can prove all of the above to an auditor, insurer or inspector.

Why is SDS management important in laboratories?

SDS management matters for five reasons: it is a legal duty, suppliers do not always push updates to you, it protects people at the moment of exposure, it decides how well an emergency goes, and it is what auditors and insurers check first.

1. It is a legal requirement in the US and the EU

Requirement	United States (OSHA HCS, 29 CFR 1910.1200)	European Union (REACH, Regulation (EC) 1907/2006)
Who must hold an SDS	Every employer must have an SDS in the workplace for each hazardous chemical it uses. Laboratories must keep the SDSs received with incoming shipments ((b)(3)(ii)).	Suppliers must provide an SDS for hazardous substances and mixtures (Art. 31(1)); downstream users, including labs, receive and use it.
Accessibility	Readily accessible to employees in their work areas during every shift; electronic access allowed if it creates no barrier ((g)(8)).	Provided free of charge on paper or electronically (Art. 31(8)).
Format	16 sections in a fixed order, in English ((g)(2)).	16 headings, dated (Art. 31(6)), in an official language of the Member State where it is placed on the market (Art. 31(5)).
Updates	New significant hazard information must be added within three months ((g)(5)).	Supplier must update without delay when new hazard or risk-management information appears, and after an authorisation or restriction (Art. 31(9)).
Record keeping	SDSs must be available on request to employee representatives and OSHA ((g)(11)).	Information needed for REACH duties must be kept for at least 10 years after the substance was last used (Art. 36).

Sources: OSHA 29 CFR 1910.1200, REACH Article 31, REACH Article 36.

Hazard Communication is not a niche rule. It was the second most frequently cited OSHA standard in fiscal year 2025 (Oct 2024 – Sep 2025), behind only construction fall protection (OSHA Top 10).

2. Suppliers will not always tell you when an SDS changes

Under REACH, a supplier must send a revised SDS only to customers it supplied in the preceding 12 months (Art. 31(9)). A bottle bought three years ago and still on your shelf can therefore carry an SDS that is out of date, and nobody will notify you. The only reliable defence is a lab-side review cycle.

The US rules are also changing. OSHA’s 2024 update to the Hazard Communication Standard aligns it with GHS Revision 7. Manufacturers had to reclassify substances by May 19, 2026, and employers must update labels, their hazard communication program and training for newly identified substance hazards by November 20, 2026. For mixtures the deadlines are November 19, 2027 (suppliers) and May 19, 2028 (employers). Many SDSs in circulation are being reissued right now.

3. It protects people at the moment of exposure

The SDS is where a researcher finds first-aid measures (Section 4), the gloves and respirator to wear (Section 8) and the incompatible materials to keep apart (Section 10). An SDS that is missing, outdated or hard to find fails exactly when someone needs it.

4. It shapes how emergencies end

Fire crews and first responders need to know what is stored where, in what quantity, and how to fight it (Section 5) or contain it (Section 6). If the SDS is buried in a binder in a locked office, that knowledge arrives too late.

5. It is what audits and insurers check

Inspectors routinely ask to see the SDS for a chemical picked at random from a shelf. Insurers and internal auditors expect a historical record of which SDS version was in force at a given time. Both are easy to show when SDSs live inside the inventory system, and hard to show when they live in folders.

What are the most common SDS management problems in labs?

Most labs do not lack SDSs on purpose. They lose track of them because the SDS collection and the chemical inventory are kept in two different places. Typical symptoms:

Missing SDSs. Chemicals arrive, get shelved, and the SDS that came with the shipment is never filed. Samples transferred between groups often arrive with no SDS at all.
Outdated SDSs. The binder or shared drive holds the version from the first purchase, years ago. Nobody knows whether a newer one exists.
Orphan SDSs. The folder still holds SDSs for chemicals that were used up or disposed of, so it no longer reflects what is actually on site.
Wrong language or region. A multinational supplier’s SDS in English is filed, but local law requires the local language (REACH Art. 31(5)).
No overview. The safety officer cannot answer simple questions such as “how many of our chemicals have no SDS?” or “which SDSs are more than three years old?” without a manual count.
Slow access in an emergency. Responders have to find the right person, the right room and the right binder before they can read Section 5.
No history. When an old SDS is replaced, the earlier version is thrown away, so the lab cannot show which hazard information was in force at the time of an incident.

Why manage SDSs together with your chemical inventory?

Because the inventory already knows which chemicals you have, how much, and where. Attaching the SDS to each inventory record turns SDS management from a separate filing job into a by-product of normal inventory work. OSHA itself expects the two to line up: the written hazard communication program must include a list of hazardous chemicals identified by a product identifier that is referenced on the matching SDS (1910.1200(e)(1)(i)).

Question	Standalone SDS folder or binder	SDS linked to the chemical inventory
Does every chemical on site have an SDS?	Manual cross-check between two lists	One search filter: “Missing SDS”
Which SDSs are out of date?	Open each file and read Section 16	Search filter on SDS revision or expiry date
Is the folder in sync with what is on the shelves?	Drifts as chemicals are used up or disposed of	Always in sync: the SDS follows the inventory record
Where is this hazardous chemical, and how much is there?	Not answered	Location and quantity sit next to the SDS
Can a responder reach the SDS from the container?	Only by finding the binder	Scan a QR code on the bottle label
Can I prove compliance to an auditor?	Build a report by hand	Export an SDS report in minutes
Which SDS version was valid last year?	Usually lost	Archived versions kept with the record

The linked approach is also easier for researchers. They already search the inventory to find or order a chemical; the SDS is one click away in the same place, so nobody needs to remember a second system.

How to set up SDS management in your lab: 7 steps

These steps work with any system, but each one is far easier when the SDS lives on the chemical’s inventory record.

Build or clean up the chemical inventory. Every container gets a unique barcode or ID, a location and a quantity. You cannot manage SDSs for chemicals you do not know you have.
Attach an SDS to every hazardous chemical. Start with the SDS that came with the shipment; if there is none, download the current one from the manufacturer or supplier.
Record the SDS metadata, not just the PDF. Capture the revision number, the revision date from Section 16, the upload date, the language and the region. This is what makes searching and reporting possible.
Set a review interval. Decide how often an SDS should be checked for a newer version (for example every 1–3 years, or shorter for high-hazard substances) and let the system flag SDSs that pass that date.
Make access immediate. Give every user read access to SDSs, and print a QR code linking to the SDS on container labels so it can be opened from the bench or by emergency responders.
Archive, never delete. When a new version arrives, keep the old one as an archived record. Under REACH, information needed for compliance must be kept for at least 10 years after a substance was last used.
Report on it regularly. Run a monthly or quarterly report of missing and expired SDSs, assign owners, and track the numbers down to zero.

How Labcup handles SDS management inside the chemical inventory

Labcup is a cloud-based laboratory inventory management system used by research universities and life-science companies. In Labcup, every SDS is attached to the chemical’s record in the chemical inventory, so each step above happens where users already work.

SDS management need	How Labcup does it
Get the SDS in	SDSs are pulled in automatically from Labcup’s reference catalogue where available, or uploaded by users as PDF. The fastest way to add one is to drag and drop the file onto the chemical in the search results.
Capture the metadata	Labcup reads the SDS version number and the latest date printed on the SDS (creation, revision, printout or download date), and fills in language and region automatically where possible. It records the upload date and whether the SDS came from the catalogue or a user.
Find missing SDSs	A “Missing SDS” search filter on the Inventory page, the Safety search page and the Stock control → Review Chemical’s Data page lists every chemical without an SDS.
Flag outdated SDSs	The host administrator sets an SDS expiry time in days (Administration → Inventory Configuration → Chemical → General → SDS Expiry). Expiry date = upload date + expiry time. Expired SDSs show a yellow triangle in the “Hazard labels” column and can be listed with the “Expired SDS” filter.
Check for newer versions	External lookup and update buttons compare against a reference catalogue and appear only when a newer SDS version is available. Direct links to the supplier’s or manufacturer’s SDS page are also shown.
Keep a history	Uploading a new SDS automatically archives the previous version. All versions are kept unless explicitly deleted, and the “Show archived” toggle displays them, supporting insurance and audit needs.
Support several languages	Each enabled SDS language (Administration → Host configuration → SDS Languages) is tracked separately, and the latest SDS per language is shown on the chemical’s data sheet.
Report on compliance	Any inventory or safety search can be exported to XLS with the “SDS All” column: revision, revision date, upload date, comment and expiry date for each language. The safety officer sees at a glance how many chemicals are missing SDSs.
Reach the SDS in an emergency	Labcup’s label designer can print a QR code on each container label that opens the chemical’s SDS directly, so responders get first-aid and fire-fighting information in seconds.
Control who changes what	Any user can open an SDS; only users with edit rights can upload or update one. Changes to inventory items are recorded in Labcup’s audit log.

Two design choices are deliberate. First, Labcup never replaces an SDS in your approved database automatically: a person reviews and uploads each new version, because keeping the SDS current remains the user’s legal responsibility. Second, because the SDS sits on the inventory record, the same GHS data feeds Labcup’s other safety features, including automatic IFC hazard classification and NFPA 704 rating, maximum allowable quantity (MAQ) tracking and the live hazard information on digital floorplans and the emergency page.

Example: clearing an SDS backlog in Labcup

Open the Safety search page and switch on the “Missing SDS” filter. Click Search.
Drag each available SDS PDF onto the matching chemical in the results.
Switch to the “Expired SDS” filter and repeat, using the external update button where a newer version is offered.
Enable the “SDS All” column and click Export to produce an XLS report for your safety committee.

Make SDS management a by-product of your inventory

SDS management is required by law, it protects researchers and responders, and it is one of the first things an inspector or insurer checks. It becomes hard only when SDSs are kept apart from the chemicals they describe. When every SDS is attached to the chemical’s inventory record, finding missing SDSs, flagging outdated ones, keeping an archive and proving compliance each take a search and a click.

Labcup builds SDS management into its chemical inventory: automatic SDS sourcing, missing and expired SDS filters, configurable expiry, versioned archives, multi-language support, exportable SDS reports and QR-coded labels that open the SDS from the bottle.
