Safety data sheets and the chemical substances and SDS register: what really has to be under control

The sheet has sixteen sections, but the shop floor works with five. Section 2 covers hazards and hazard statements — this is where you check whether the substance is carcinogenic, mutagenic, toxic for reproduction or a strong sensitiser, because that changes health surveillance and register requirements.

Section 4 is first aid, content that must be available immediately rather than after a call to the office. Section 7 covers storage and incompatibilities, answering what must not stand next to what. Section 8 gives limit values and required personal protective equipment, and section 13 covers waste and residues.

The practical consequence is that a worker does not need to read the whole sheet. They need an extract of those sections at the workstation, with the full sheet available on demand — for example after scanning a code on the rack.

That extract becomes the workstation card: a single page with the GHS pictograms, the signal word, the key hazard and precautionary statements, the required protective equipment and first-aid rules. It is a document a worker reads in half a minute — unlike the sixteen pages of the full safety data sheet.

A sheet has no expiry date in the everyday sense, but it becomes outdated when the classification changes, the mixture composition changes, regulations change, or the supplier changes. The manufacturer must send an updated version to recipients, but in practice the new sheet lands in the purchasing inbox and stays there.

An effective mechanism is simple: at every delivery, the person receiving goods checks the sheet date and version on the packaging or documents against the version in the register. A mismatch creates a task for whoever owns chemicals.

The second mechanism is a periodic register review — quarterly for high-hazard substances, annually for the rest. The review also asks whether the substance is still used. Removing an entry matters as much as adding one.

In practice, most of the time goes not to reading sheets but to retyping them: copying hazard statements into the risk assessment, copying protective equipment into the workstation card, copying the name and supplier into the register. Every retyping is a chance for an error and one more document version to track.

In VIMS the workflow starts with uploading the safety data sheet PDF to the chemical substances and SDS register. The system reads the key data from the document — product name, manufacturer, pictograms, hazard and precautionary statements, required protective equipment — and transfers it to the substance record. From that data it generates a printable workstation card, and a QR code at the rack or workstation lets a worker open the full sheet on a phone.

When the supplier sends a new version, uploading it to the same record updates everything in one place: the register version, the workstation card and the content behind the QR code. No replacing pages in binders, no checking which copy on the floor is current.

The chemical substances and SDS register is not a standalone document. Substance properties determine the scope of workplace exposure measurements, and those results shape the scope and frequency of health surveillance and the content of the risk assessment.

Introducing a new substance should therefore raise three questions automatically: does the measurement list change, does the health surveillance referral for people at that workstation change, and does the risk assessment need review. If only one person's memory asks those questions, sooner or later one will be missed.

A safety data sheet (SDS, formerly MSDS) is the supplier's 16-section document required by Article 31 of REACH, in the official language of the country where the product is placed on the market. The supplier provides and updates it; the employer makes it available to workers.

CLP is the classification, labelling and packaging regulation: GHS pictograms, signal words and H (hazard) and P (precautionary) statements. The UFI (unique formula identifier) is a 16-character code on hazardous mixture labels linking the product to its PCN notification to poison centres via the ECHA portal; for industrial-use mixtures the UFI may appear in SDS section 1 instead of the label.

SDS vs workstation chemical card: the SDS is the supplier's document, while the workstation card is the plant's extract — hazards, protection, first aid and spill response in language workers understand. See the chemical register and SDS module.

CMR substances are carcinogenic, mutagenic or — after the EU amendment — reprotoxic. Work exposing staff to them requires a register of work and of exposed workers, kept for 40 years, and annual reporting to the sanitary inspectorate. Stricter measurement intervals are covered in the exposure measurements guide.

The most common is straightforward: the sheet is in a binder in the office and unavailable at the workstation. The second is a substance standing in the hall and missing from the register. The third is decanting into an unlabelled container — a frequent and risky shortcut when diluting cleaning agents.

The fourth concerns storage: incompatible substances kept together, no spill containment, no ventilation. The fifth is inconsistency between the chemical substances and SDS register, the risk assessment and health surveillance referrals — three documents describing three different realities.
