What is hazardous substance storage?

Hazardous substance storage involves safely storing chemicals or materials that are flammable, toxic, corrosive, or otherwise dangerous to people or property, in accordance with legal regulations.

What UK regulations govern hazardous substance storage?

Storage is governed primarily by the Control of Substances Hazardous to Health (COSHH) Regulations 2002, the Planning (Hazardous Substances) Regulations 2015, and health and safety laws enforced by the HSE.

Why is proper hazardous substance storage important?

Correct storage prevents leaks, spills, fires, explosions, and poisoning risks, protecting worker safety, the environment, and complying with legal requirements.

What types of hazardous substances require special storage?

Flammable liquids, corrosive acids and alkalis, toxic chemicals, oxidisers, and compressed gases typically require dedicated storage solutions.

What are COSHH storage requirements?

COSHH requires businesses to store only the minimum amount needed, keep substances secure in designated areas or cabinets, restrict access to authorised personnel, and follow safety data sheet (SDS) instructions.

What is the recommended storage capacity for flammable liquids?

Only up to 50 litres of extremely flammable liquids (flashpoint below ambient temperature) can be stored in appropriate cabinets without additional controls, with larger volumes subject to stricter regulation.

Are there special cabinets for hazardous substances?

Yes, hazardous substance storage cabinets are designed with chemical-resistant materials, secure locking doors, ventilation options, spill containment, and fire-resistant properties.

How should hazardous substances be stored within cabinets?

Substances should be separated by compatibility groups, kept in original labelled containers, spill trays or bunds should be used, and heavier containers placed on lower shelves.

What security measures should be in place for hazardous substance storage?

Restricted access, locking storage units, fencing, alarms, and controlled entry systems ensure only authorised personnel can access substances.

Can hazardous substances be stored outdoors?

Yes, but storage areas must be secure, weatherproof, ventilated, and comply with COSHH and local authority requirements to reduce environmental risk.

How often should hazardous substance storage areas be inspected?

Regular inspections and maintenance are essential, including checking container integrity, labels, ventilation systems, and spill containment equipment.

What safety signs are required for hazardous substance storage?

Clear hazard signage compliant with UK regulations must be displayed, indicating chemical types, risks, and emergency procedures.

What should I do if a hazardous substance container is damaged?

Immediately isolate the container, follow spill containment procedures, dispose of or repair the container according to SDS guidelines, and report incidents as required.

Are there size limits for hazardous substance storage areas?

Yes, regulations specify maximum quantities depending on substance type and location, with larger volumes requiring hazardous substances consent from local authorities.

Can incompatible hazardous substances be stored together?

No, incompatible substances such as acids and alkalis, or oxidisers and flammables, must be stored separately to prevent dangerous chemical reactions.

What ventilation requirements apply to hazardous substance storage?

Proper ventilation prevents accumulation of hazardous vapours; specific ventilation standards depend on substances stored and quantity.

How can businesses ensure compliance with hazardous substance storage regulations?

Conduct a COSHH risk assessment, follow SDS instructions, implement secure and appropriate storage solutions, train staff, and maintain records and inspections.

What kind of hazardous substance storage products does Action Handling offer?

Action Handling supplies chemical storage cabinets, spill containment pallets, ventilated stores, and bunded units designed to meet COSHH and safety standards.

Are hazardous substance storage cabinets fire-resistant?

Many cabinets have fire-resistant properties and are designed to withstand heat to protect contents during an emergency.
