Housekeeping, Not Chemistry: A Six-Monthly Substance Store Check for UK Managers
Most UK workplaces keep a modest store of substances that are not especially exotic: washing-up liquid, disinfectant, bleach, degreaser, paint, lubricant, sealant and the occasional aerosol. They are often kept in a cupboard under the stairs, a locked maintenance cabinet or a corner of a plant room. Because they are familiar, they are easily overlooked.
A six-monthly substance store check is not a substitute for a COSHH assessment. It is the housekeeping layer that keeps an assessment credible. The distinction matters. Managers who are not chemists can still verify that containers are labelled, that safety data sheets are present, that incompatible products are separated and that spill provisions exist. That work takes less than half an hour if the store is reasonably organised.
Why a cupboard check is not a COSHH assessment
The Control of Substances Hazardous to Health Regulations 2002 require employers to assess the risks arising from work with hazardous substances, prevent or adequately control exposure, and review the assessment when circumstances change. A visual check of a store does not decide whether exposure is adequately controlled. It does, however, confirm whether the basic conditions for control are still in place.
Think of the check as an audit of storage discipline. It answers practical questions: can staff identify what they are using, can they find the relevant safety data sheet, are products stored in a way that reduces the chance of a dangerous reaction, and is there a sensible response to a small spill? Those answers feed the COSHH assessment rather than replace it.
What to take with you
Keep the visit simple. Take the current substance inventory, the one-page record sheet, a torch, a pen and a camera or phone for photographs of defects. Gloves are sensible if containers are dusty or damaged, but the check should not require opening sealed containers or decanting products.
If the store is locked, confirm who holds the key and whether the access list is still accurate. A cupboard that only one person can open is a resilience risk, not a compliance achievement.
The thirty-minute sequence
1. Inventory and labels
Start with a quick count. Compare what is physically present with the inventory. Look for unlabelled containers, faded labels, handwritten bottles and products decanted into drinks bottles or food containers. Any decanting into unlabelled packaging is a stop item: it should be corrected immediately, not noted for later.
Check that labels are legible and that hazard symbols and signal words are visible where required under GB CLP. A label that has been wiped clean by condensation or obscured by tape is a small defect with a large consequence.
2. Safety data sheets
Confirm that a current safety data sheet is available for each product. Paper is acceptable if it is accessible in the store or a known folder; digital access is acceptable if staff can reach it without leaving the area or hunting through a shared drive. The check is not a scientific review of the sheet. It is a confirmation that the document exists, relates to the product actually held and is not for a discontinued formulation.
Where a product has been replaced, remove the old sheet from the working folder and archive it if retention is required. A folder full of superseded sheets creates false confidence.
3. Segregation and storage
Look at what is stored next to what. Bleach and acidic cleaners should not be positioned where a leak could mix them. Oxidisers should be kept away from solvents and combustible materials. Aerosols should not be stored near heat sources or in direct sunlight. Flammable liquids may bring DSEAR considerations if quantities are more than trivial, so note the volume and location rather than guessing.
Check that containers are upright, closed and not leaking. Look at the floor of the cupboard for staining, corrosion or crystallised residue. These are signs of past leaks and may indicate that the base of the store is unsuitable or that containers are deteriorating.
4. Ventilation and spill provision
A small, well-ventilated store is easier to manage than a sealed cupboard that smells strongly when opened. Confirm that vents are not blocked by boxes or bags. If the store has no ventilation, record the fact and consider whether the volume and type of substances remain suitable for that space.
Check that a spill kit is present, complete and appropriate. For a general cleaning store, absorbent granules, a scoop, disposable bags and gloves may be enough. For larger quantities or flammable products, the provision should match the risk. A spill kit that has been used and not restocked is worse than an obvious gap because it suggests readiness that does not exist.
5. Expiry and condition
Look for out-of-date products, swollen containers, rusted tins and damaged caps. Some substances become more hazardous with age, and some simply lose effectiveness. Record the date received where known and operate a first-in, first-out approach. If the store contains products that nobody can remember using, that is a sign to challenge whether they are needed at all.
The one-page record
A record sheet should be short enough to complete during the visit. The following structure works for a small store:
| Check | Yes / No | Action required | Owner | Date closed |
|---|---|---|---|---|
| Inventory matches the store | ||||
| All containers labelled and legible | ||||
| Safety data sheet available for each product | ||||
| Incompatible products separated | ||||
| Containers upright, closed and undamaged | ||||
| Ventilation unobstructed | ||||
| Spill kit present and complete | ||||
| No out-of-date or unidentified stock | ||||
| Access arrangements still appropriate |
Add a short section for observations and a signature. The record should show the date of the check, the person who completed it and any actions raised. It does not need to repeat the COSHH assessment.
When the cupboard check is enough
A six-monthly check is likely to be sufficient where the store holds small quantities of common, lower-risk products, the range has not changed, staff are trained in their use, there have been no spills or incidents, and the existing COSHH assessment remains valid. In that situation, the check is a monitoring activity. It confirms that the arrangements described in the assessment still exist in practice.
It is not enough to rely on the check alone if the store is crowded, poorly ventilated or used by several teams with different working practices. Housekeeping can only support a sound assessment; it cannot compensate for one that is out of date.
When to escalate to a fuller COSHH review
Arrange a fuller review when a new substance or process is introduced, when quantities increase materially, when a container fails or a spill occurs, when someone reports symptoms that may be linked to exposure, or when the workplace or ventilation changes. A review is also needed if the safety data sheet indicates a hazard that the current assessment does not address, or if staff are unsure about handling, mixing or emergency arrangements.
For managers without a chemistry background, the safest trigger is doubt. If the check raises a question that cannot be answered from the assessment and the safety data sheet, record it and seek competent advice. That is not a failure of the check. It is the check doing its job.
The cupboard under the stairs will never be a laboratory. It can, however, be a well-run store. A short, documented inspection every six months keeps it that way and gives the COSHH assessment a firmer foundation.
