Fire-Rated Flammable Storage Cabinet

What is the Fire-Rated Flammable Storage Cabinet?

A fire-rated flammable storage cabinet is type tested to keep contents below ignition temperature for 30, 60 or 90 minutes. It suits code- or insurance-driven installations with larger solvent inventories and defined fire performance.

Overview

This cabinet is tested to EN 14470-1 or an equivalent fire test, so its construction is optimised for thermal protection in addition to spill containment. Walls use double skin, mineral insulation and intumescent door seals, and the internal temperature must stay below a defined limit for the rated period even when the exterior is exposed to a fire. Doors are self-closing with fusible links, and vent ports, if used, are fitted with fire dampers. Shelves are adjustable and load rated, and secondary trays are standard. The cabinet carries a test certificate and a rating label. It is used where local codes, insurance or a large solvent inventory demand a defined fire performance, and the certificate should be kept with the asset record.

How does it work?

A laboratory safety cabinet is a container designed to hold hazardous chemicals safely under normal use and during a fire. Flammable liquid cabinets use double walls with an air space, thermal insulation, self-closing and self-latching doors and a sill that contains spills. They keep the internal temperature below the ignition temperature of the contents for a rated period, such as 30, 60 or 90 minutes, so occupants can evacuate and the fire service can respond. Many are tested to EN 14470-1 or FM 6050, and some are vented to relieve pressure or remove vapour. Corrosive cabinets use chemically resistant linings and often ventilated extraction so acid or base vapour does not attack the cabinet or the room. Labelling, segregation by hazard class and secondary containment trays are integral to safe use, and cabinets should be closed except when loading.

What are the key features?

• Type tested to EN 14470-1, 30–90 min
• Double skin with mineral insulation
• Intumescent door seals
• Self-closing doors with fusible links
• Fire dampers on vent ports
• Test certificate and rating label

What are the technical specifications?

A typical fire-rated flammable storage cabinet configuration offers fire rating of 30, 60 or 90 min (EN 14470-1), construction of Double skin, mineral insulation, door seals of Intumescent, doors of Self-closing with fusible link, vent ports of Fire dampers if fitted and capacity of 30–250 L. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Fire-Rated Flammable Storage Cabinet is used in code-driven solvent storage, insurance-specified installations, large solvent inventories and central chemical stores. Across the wider Safety Cabinets class, laboratories also deploy it for solvent storage in chemistry laboratories, acid and base storage and pharmaceutical reagent storage.

Which standards and certifications apply?

Relevant standards and methods include EN 14470-1 (fire safety storage cabinets), NFPA 30 (flammable and combustible liquids code), OSHA 29 CFR 1910.106 (flammable liquids), FM 6050 (storage cabinets for flammable liquids), GB 15603 (chemical storage rules) and GHS labelling requirements. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place cabinets on a level, load-rated floor away from exits, heat sources and ignition points, and confirm the required distance from escape routes under local codes. Inspect doors, latches and hinges monthly and confirm self-closing and self-latching operation. Check the fire rating documentation and keep it with the asset record. If a cabinet is vented, confirm the duct does not defeat the fire rating and that the exhaust is suitable. Keep incompatible chemicals in separate cabinets, use secondary trays and never exceed the rated capacity or shelf load, since shelves may fail and spill the contents. Review stored inventory regularly and remove expired or unneeded items.

How do I select the right Fire-Rated Flammable Storage Cabinet?

Choose a fire-rated cabinet when a code, insurer or large inventory requires defined fire performance. Confirm the rating period and keep the test certificate. RFQ: rating required, capacity, venting, width and placement. Always ask for the type test certificate.

How does it compare with other Safety Cabinets variants?

Select the cabinet by hazard class and quantity. For flammable liquids, confirm the fire rating and capacity in litres, and whether the cabinet must be fire rated under EN 14470-1 or listed to NFPA 30 and FM 6050. Choose a corrosive cabinet with a resistant lining and, where required, ventilation for acids or bases separately. Decide between freestanding, under-bench and ventilated versions to suit the room layout and airflow. Check door operation, sill height, shelf adjustability and load capacity, and plan secondary containment trays. Confirm that placement meets local codes, including distance from exits and ignition sources, room ventilation and signage. Document installation, inspection and any venting arrangement, and train staff to keep doors closed.
