How should workplace chemicals be stored and labelled?

Why a tidy cupboard can still be unsafe

Neat shelves do not show chemical compatibility, whether a container is suitable or whether a spill would reach food or people. HSE’s hospitality cleaning-substance guidance advises following manufacturer storage instructions and avoiding food or drink containers for hazardous cleaning products.

The plan must cover receipt, put-away, dispensing, use, returns and disposal. A safe main store does not resolve an unidentified bottle left beside a working sink.

Build the storage plan from actual stock

Create an inventory with product name, supplier, location, quantity and a route to the current safety data sheet. Use HSE’s safety data sheet guidance to distinguish supplier hazard information from the workplace assessment you must make.

HSE’s food-and-drink disinfectant guidance includes storage, chemical compatibility and emergency arrangements within the assessment.

Keep the identity and hazards clear at the point of use

Retain readable original labels and use suitable, clearly identified containers for authorised transfers. Never use a food or drink container for hazardous cleaning substances. If the identity is uncertain, stop use, isolate it safely under the site arrangements and obtain competent help; do not identify it by smelling or mixing it.

Workplace container and pipe marking duties are addressed in HSE’s safety-signs guidance. Supply labels and workplace marking are not identical rules in every circumstance. Agree the required marking and instruction for your system rather than assuming every temporary container needs precisely the same label format as a newly supplied product.

Assess health exposure and fire risks separately

COSHH controls health risks from hazardous substances. A store may also need assessment under GB DSEAR guidance for the safety hazards within that regime. A COSHH sheet alone does not demonstrate that those issues have been resolved.

Northern Ireland has its own COSHH framework and separate DSEAR regulations. Do not automatically import the scope of later GB changes into NI. Obtain competent advice for specialist storage arrangements and applicable fire duties.

Example: checking a shared cleaning cupboard

A café supervisor finds an unmarked spray bottle, a leaking returned container and products arranged only by bottle size. Staff stop using the unidentified bottle and follow the site’s defect and spill arrangements. The supervisor reconciles the inventory with supplier information, agrees compatible locations and records who may decant.

The resulting check is specific: labels readable, approved containers closed, assigned locations used, no damaged stock left unresolved and the spill route accessible. “Cupboard tidy” would not capture those decisions.

Common mistakes

• Using a generic colour chart instead of actual incompatibility information.
• Buying a cabinet without checking its suitability for the contents.
• Allowing decanting without an agreed container and identification method.
• Keeping damaged or obsolete stock without an action owner.

Next steps

Walk the full route from delivery to disposal with the inventory and supplier instructions. Correct identification and container problems promptly, then record the storage decisions and responsible person.
