What this is
What is a chemical and substance register?
What is a chemical and substance register?
It is the inventory of hazardous products present at a site, one row per product as supplied, holding the identity on the container, the manufacturer, the label hazard information, the current safety data sheet, the storage location and the maximum quantity held. It is master data: created once per product and maintained while the product is on site, with assessments, storage checks and training records referring back to it.
Is the register the same thing as the safety data sheet library?
No, and treating them as one is the most common design error. The data sheet is the manufacturer's sixteen-section document; the register is your record of which products you hold, in what quantity, where and for what task. A complete sheet library says nothing about whether a product is still on site, and an inventory without sheets says nothing about the hazard.
What counts as a hazardous substance for register purposes?
Anything classified as hazardous under the applicable GHS implementation, plus substances hazardous to health carrying no supplier classification at all: welding fume, silica, flour and wood dust, exhaust emissions and anything else the work itself generates. Registers built only from purchased labelled products miss the generated ones, which is where several of the serious occupational disease exposures sit.
Scope
When is a chemical and substance register required?
This register is foundation master data for everything chemical, and its most common misuse is being asked to be the assessment. The row holds identity, hazard classification, data sheet currency, quantity and location; the judgement about whether the substance can be used safely in a given task belongs elsewhere.
Use this template when
- A site is being set up and the products already in stores, workshops and laboratories need rows
- A new product is being introduced, including trials, samples and one-off purchases
- A supplier has reissued or revised the safety data sheet, or reformulated the product
- A product is being withdrawn and the last container has left site
- Storage location, maximum quantity held or the tasks the product is used in have changed
Do not use it for
- Holding the sixteen-section data sheet content itself, which belongs in Safety Data Sheet (SAF-176); the register holds the file, the issue date and the pointer
- Assessing exposure and controls for a task, which belongs in Chemical Risk Assessment (SAF-086) against the substance as used
- Deciding what may be stored next to what, which belongs in Chemical Storage Compatibility Check (SAF-087) using section 7 and section 10 data
- Recording workplace labels for decanted containers, which belongs in Workplace Label Record (SAF-177)
- Combustible dust and explosive atmosphere work, which belongs in Dust Hazard Assessment (SAF-090) and Explosive Atmosphere Zoning Record (ENV-050)
Compliance mapping
Which WHMIS 2015 requirements does this satisfy?
Chemical inventory is one of the few records that regulation names explicitly. Hazard communication regimes require a list, require the data sheets behind it to be current and accessible, and in Australia require the register to be produced on request.
| Clause | Requirement | Where it lands |
|---|---|---|
| OSHA 1910.1200(e)(1)(i) | Written hazard communication programme to include a list of the hazardous chemicals known to be present, using an identity referenced on the appropriate safety data sheet | Identification |
| OSHA 1910.1200(g)(8) | Safety data sheets maintained and readily accessible to employees in their work area during each work shift | Hazard information |
| OSHA 1910.1200(f)(6) | Workplace containers labelled with the product identifier and words, pictures or symbols conveying the hazards | Hazard information |
| Hazardous Products Regulations SOR/2015-17, Schedule 1 | Sixteen-section data sheet content and label elements, including signal word, hazard statements and pictograms, under WHMIS 2015 | Hazard information |
| WHS Regulation 344 (Australia) | Register of hazardous chemicals used, handled or stored, containing the current safety data sheet for each, kept readily accessible to workers | Related records |
| COSHH 2002 reg.6 | Suitable and sufficient assessment of risk to health from substances as used, which presumes the substance, its exposure limit and the task are known | Storage and use |
| DSEAR 2002 reg.5 | Risk assessment for dangerous substances, informed by flash point, physical state and the quantity held at the location | Storage and use |
| CLP Regulation (EC) 1272/2008 art.17 | Label content for substances and mixtures classified as hazardous, including signal word, hazard statements and pictograms | Hazard information |
What it does not cover
- The safety data sheet, which is the manufacturer's sixteen-section document; the register holds a copy and an issue date, and cannot substitute for the sheet being current and reachable at the point of use.
- Chemical risk assessment, which must address the substance as used, including quantity, method, duration, ventilation and who else is in the area, none of which the register captures.
- Storage segregation, which requires a compatibility check against section 7 and section 10 of each data sheet; the free-text incompatible-with field is a reminder, not an assessment.
- Hazard communication training and workplace labelling, which are separate duties under OSHA 1910.1200(f) and (h) and under WHMIS worker education requirements.
- Quantity-threshold regimes, which include process safety management under 29 CFR 1910.119, EPCRA sections 311 and 312 reporting, Seveso III and the WHS manifest, each with its own list and its own arithmetic.
Global
Chemical and Substance Register requirements by country
Every GHS jurisdiction requires labels, data sheets and worker information. They diverge on whether the inventory itself is mandatory, whether it must be produced on request, and at what holding the reporting regimes begin.
29 CFR 1910.1200; EPCRA sections 311 and 312, 40 CFR 370
The hazard communication programme must include a list of hazardous chemicals present, and holdings above threshold trigger annual inventory reporting to state and local authorities and the fire department.
The same inventory serves the safety programme and the Tier II filing, so a register that omits quantity cannot support the reporting duty at all.
COSHH 2002 reg.6 and reg.7; DSEAR 2002; GB CLP
No standalone inventory duty, but assessment, control and fire and explosion duties all presume a known population of substances and quantities.
HSE inspectors work outwards from the inventory, comparing it to the store room, so an inventory shorter than the shelf is where the visit starts going badly.
Regulation (EC) 1272/2008 (CLP); Regulation (EC) 1907/2006 (REACH) art.31; Chemical Agents Directive 98/24/EC art.4
Suppliers classify and label, provide data sheets on request, and employers must determine whether hazardous chemical agents are present and assess the risk.
Determining presence is the inventory duty in all but name, and it applies to agents generated by the work as well as products purchased.
WHMIS 2015 under the Hazardous Products Act and Regulations; provincial OHS and Canada Labour Code Part II
Suppliers must classify to GHS and provide compliant labels and sheets; employers must maintain data sheets, label workplace containers and educate workers.
Employer duties are provincial, so a multi-province operation has one supplier regime and several employer regimes, and the register is the common denominator.
Model WHS Regulations reg.344 and reg.346
A register of hazardous chemicals with current data sheets is mandatory and must be readily accessible; above Schedule 11 quantities a manifest is also required.
The most explicit inventory duty in the common-law world: an inspector can ask for the register, and an out-of-date sheet in it is a breach on its own.
UN GHS; ISO 45001 cl.6.1.2
GHS provides the classification and communication grammar; ISO 45001 requires proactive hazard identification covering substances and how work is organised.
GHS revisions are adopted at different dates in different jurisdictions, so the same product can carry different classifications in two of your sites legitimately.
How to complete it
How to complete a chemical and substance register, step by step
The form asks for the label, the sheet and the store. The judgements that decide whether the register is worth anything are about what counts as a row, how a row is keyed, and how a row ends.
The purchasing catalogue is the wrong source. Walk the stores, workshops, laboratories, maintenance vans, cleaning cupboards and roof plant, and register what is physically there, including the decanted bottles, the trial samples and the drum a contractor left behind. The first walk on a mature site routinely finds products the system knew nothing about, and about half of those have no data sheet on site.
Product Name is what every downstream pick list displays, and product names are neither unique nor stable. Two manufacturers sell degreasers with near-identical names and wholly different classifications, and one manufacturer will reformulate under an unchanged name. The manufacturer recorded alongside the identifier is what makes a row resolvable; CAS numbers help for single substances and are meaningless for mixtures, which is most of what a site holds.
Maximum Quantity Held is optional in the form and decides whether an entire regulatory regime applies to you. Settle what it means before anyone fills it in: maximum per storage location, or aggregate across the site. The thresholds that matter are aggregate, and a register of per-cupboard maxima cannot be summed into them.
A withdrawn product leaves behind a spill plan, a training module, an assessment and a storage rule that all still reference it, plus a row that still appears in every chemical picker. Set the state when the last container leaves site, not when the last order is cancelled, and keep the row rather than deleting it: the exposure history of anyone who worked with it depends on the register knowing the product was once here.
What auditors find
Most common chemical and substance register findings
Chemical register findings divide neatly into two. The inventory does not match the shelf, or the inventory matches the shelf but the hazard information behind it is stale.
| Finding | Clause | What fixes it |
|---|---|---|
| Products found in stores, workshops or vehicles with no row in the register. | OSHA 1910.1200(e)(1)(i) | Gate chemical entry to site through an approval request, and reconcile the register to a physical walk at a stated frequency. |
| Safety data sheet in the register is superseded by a revision the supplier has already issued. | WHS Regulation 344 | Trigger review on receipt of a new sheet or a delivery of a new batch, not only on the calendar review date. |
| Data sheets held centrally and not reachable by workers in the area where the product is used. | OSHA 1910.1200(g)(8) | Make sheets accessible at the point of use on every shift, including when the network or office is unavailable. |
| Decanted containers in use with no workplace label and no corresponding register entry. | OSHA 1910.1200(f)(6) | Require a label record for every decant, referencing the parent product row rather than creating a new one. |
| Hazard information in the register does not match the label on the container. | CLP Regulation (EC) 1272/2008 art.17 | Populate hazard fields from section 2 of the current sheet, not from the previous row or from memory. |
| Incompatible products stored together despite both being registered. | COSHH 2002 reg.7 | Run a compatibility check from sections 7 and 10 for the products actually sharing each store, and set the segregation rule there. |
| Exposure limit blank for substances that have one, so no basis exists for monitoring or control. | COSHH 2002 reg.6 | Populate the limit and its basis from the sheet or the national list, and flag substances requiring health surveillance. |
| Substances generated by the work, dusts, fume, mists, absent from the register entirely. | ISO 45001 cl.6.1.2 | Add process-generated agents as rows with their own assessments; no supplier will send you a sheet for them. |
| Quantities not recorded or recorded inconsistently, so threshold applicability cannot be determined. | 40 CFR 370 | Define the quantity basis, then hold maximum quantity per location and derive the site aggregate from it. |
| Withdrawn products still active in the register and still selectable in downstream pickers. | WHS Regulation 344 | Set the state when the last container leaves site and exclude non-current products from selection while retaining the history. |
Case in point
Case in point: the sanitiser that changed without changing its name
A food plant had held the same sanitiser in its wash bay for six years. The register row was accurate when it was written: a quaternary ammonium product, corrosive, no oxidiser hazard, and the incompatible-with field read strong acids only as a general caution. The data sheet on file was issued in 2019 and had been reviewed twice, both times by confirming that a sheet existed and was under three years old at the time of the check.
The supplier reformulated to a chlorine-releasing chemistry and kept the trade name and the pack. Deliveries continued, the label changed, and nobody compared it to the register, because the name in the ordering system had not changed and the register was keyed on that name. Eight months later a night-shift cleaner topped up the wash-bay dispenser from an acid descaler drum on the same racking, and the reaction released chlorine into a small, poorly ventilated room. Two people went to hospital.
The register had not been neglected. It had been maintained against the wrong key and the wrong trigger. The corrective actions were narrow: key rows to product identifier plus manufacturer plus sheet revision, treat receipt of a revised sheet as the review trigger rather than the age of the sheet, and derive segregation from the current classification rather than from free text written once.

From a document you fill in to a programme that runs itself
The register is a table. What fails around it is the flow of chemicals on and off site: the product that arrived through engineering, the sheet revised without anyone comparing it, the withdrawn product still selectable in every picker.
Holds chemical assessments, storage compatibility checks, spill kit inspections and workplace labels against the substance row rather than as separate lists.
Watches deliveries, approval requests and revised data sheets for changes that should invalidate a row, and raises the review before the calendar date arrives.
Connects exposure limits and health-hazard classifications to monitoring and health surveillance, so a substance with a limit produces a programme rather than a field.
Takes environmental hazard classification, quantity and storage into spill response, restricted substance compliance and substitution assessment.

Chemical and Substance Register definitions and key terms
- Product identifier
- The name or number appearing on both the label and section 1 of the data sheet, which is the only value that reliably links the container to the record.
- Hazard class and category
- The GHS classification of a hazard and its severity band, such as flammable liquids category 2, which together determine signal word, statements and control expectations.
- Signal word
- Danger or Warning, assigned by the classification and printed on the label; danger denotes the more severe categories and is not a matter of judgement.
- CAS number
- A unique registry number for a single chemical substance, useful for pure substances and inapplicable to mixtures, which is what most workplace products are.
- Occupational exposure limit
- The airborne concentration a worker may be exposed to over a stated reference period, set nationally, and the reference point for monitoring and control adequacy.
- Flash point
- The lowest temperature at which a liquid gives off enough vapour to ignite, which drives flammability classification, storage rules and explosive atmosphere zoning.
- Workplace label
- The employer-applied label required on decanted containers, carrying the product identifier and hazard information in words, pictures or symbols.
- Manifest quantity
- The holding above which a separate manifest and notification to the regulator is required, a distinct duty from the register itself in Australian WHS regulation.
FAQ
Frequently asked questions about chemical and substance register
Does the register have to include cleaning products and office consumables?+
If they are classified as hazardous, yes. Household-strength products are the ones most reliably left out and most reliably involved in incidents: bought outside procurement, decanted freely, used by people who never received chemical training. The exemption worth reading carefully covers consumer products used in the same way and quantity as a consumer would, which rarely describes industrial cleaning.
How often should safety data sheets be replaced?+
On revision, not on a birthday. Under WHMIS 2015 the supplier must update the sheet within ninety days of becoming aware of significant new hazard data, and the duty on you is to hold the current one. A three-year flag is a useful prompt to go and ask the supplier, but a sheet that is two years old and superseded is a worse problem than one that is four years old and current.
One product or one container per row?+
One product, with quantity and location as attributes. A row per container turns the register into a stock system it was never designed to be and makes the data sheet relationship many-to-one for no benefit. Where the same product is held in materially different forms or concentrations, those are different products with different classifications and deserve separate rows.
Do we need a row for substances generated by our own processes?+
Yes, and this is where most registers are thinnest. Welding fume, wood dust, flour dust, silica from cutting and diesel exhaust emissions are all substances hazardous to health with no supplier and no data sheet. Add them with the assessment and the exposure limit attached, because the assessment obligation does not depend on somebody having sold you a labelled container.
Can the register be the safety data sheet library?+
It can hold them, and it should not be described as being them. The register answers what we hold, where and how much; the library answers what this substance is. Merging them tends to produce a register that is maintained whenever a sheet arrives, which is precisely the trigger that reformulation and new products defeat.
What is the fastest way to make a stale register usable again?+
A physical walk, store room by store room, comparing shelf to register in both directions, photographing the label as you go. Reconcile missing rows first, then stale sheets, then quantities. The reverse order, tidying data before establishing what is on site, produces a clean register that is still wrong.
