Corrosive Storage Cabinet

What is the Corrosive Storage Cabinet?

A corrosive storage cabinet has a chemically resistant lining for acids or bases, often with ventilation. It protects the cabinet and the room from aggressive vapours. It also limits corrosion damage to nearby equipment.

Overview

The cabinet is built with a steel or plastic body and a polypropylene, polyethylene or epoxy lining that resists acid and base attack. It is usually ventilated, with a low-level inlet and a high-level exhaust to a duct or filter, because acid vapour corrodes steel and can damage nearby equipment. Shelves are non-corroding, often polypropylene, and carry 40–100 kg, and secondary trays collect drips. Storage is separated into acid and base cabinets so that neutralisation reactions cannot occur if a container leaks. Some models use an all-plastic construction for hydrofluoric acid or strong oxidisers. Capacity is typically 30–200 L. The cabinet is labelled by hazard class, and doors should be kept closed with the ventilation running.

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?

• Polypropylene or epoxy acid-resistant lining
• Low-level inlet and high-level exhaust
• Non-corroding shelving at 40–100 kg
• Separate acid and base cabinets
• Corrosion-resistant secondary trays
• All-plastic option for HF and oxidisers

What are the technical specifications?

A typical corrosive storage cabinet configuration offers cabinet type of Corrosive storage, lining of Polypropylene or epoxy, ventilation of Low inlet, high exhaust, shelf load of 40–100 kg, capacity of 30–200 L and trays of Corrosion-resistant secondary. 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 Corrosive Storage Cabinet is used in acid and base reagent storage, sample digestion reagents, battery and plating chemicals and hydrofluoric acid storage. 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 Corrosive Storage Cabinet?

Choose a corrosive cabinet with a lining compatible with the acids or bases stored, and specify ventilation where vapour is aggressive. Keep acid and base cabinets separate. RFQ: chemicals, concentrations, volumes, lining material and ventilation route.

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.
