Type 30 and Type 90 Flammable Storage Cabinets
Most organisations typically fall into one of two categories when selecting COSHH storage cabinets. The choice usually depends on the level of risk present in the workplace and the volume or type of hazardous substances being stored.
Type 30 - Suitability for lower-risk environments
Type 30 COSHH storage cabinets are used in lower-risk areas where smaller amounts of flammable liquids are stored. They provide 30 minutes of fire resistance, giving important early protection in the event of a fire.
These cabinets are suitable for small workshops, maintenance areas, or workplaces where hazardous substances are used but not stored in large volumes. They help meet COSHH requirements while offering a compact and practical storage solution for everyday use.
Type 90 - Certified fire protection for high-risk workspaces
Type 90 COSHH storage cabinets provide 90 minutes of fire resistance and are used in higher-risk environments where more hazardous substances or larger quantities are stored. They are commonly found in laboratories, manufacturing sites, and industrial workshops. The extra protection helps contain fire for longer, giving more time for evacuation and emergency response while supporting COSHH requirements in higher-risk settings.
Fire-resistant Safety Cabinets
BS EN 14470-1 is the recognised standard for fire-resistant COSHH storage cabinets used to store flammable liquids safely. While COSHH requirements set the legal duty to control hazardous substances, this standard explains how fire protection is achieved in practice.
EN 14470-1 certified cabinets are designed to stay safe and stable during a fire and are commonly used in workplaces where documented compliance is required.
They typically provide:
Certified fire resistance (Type 30 or Type 90) for 30 or 90 minutes of protection
Insulated construction to slow down heat and prevent fire spread
Automatic door closing when temperatures rise
Self-expanding seals that help contain smoke and flames
Built-in spill containment to support COSHH secondary containment requirements
Secure locking systems to prevent unauthorised access
These COSHH storage cabinets are tested under real fire conditions, helping ensure they maintain their structure and performance when it matters most.
They are widely used in laboratories, workshops, manufacturing sites, and chemical storage areas where flammable liquids are handled and strict safety standards must be met.
Choosing the Right Flammable Storage Cabinet
Choosing the right COSHH storage cabinets depends on your risk assessment and the level of fire protection needed under COSHH requirements. You must ensure flammable liquids are stored safely, kept away from ignition sources, and contained in case of a spill.
In lower-risk environments with smaller volumes, Type 30 cabinets may be suitable. For higher-risk workplaces such as laboratories, manufacturing sites, or mixed chemical storage areas, Type 90 cabinets are often the preferred option due to their increased fire resistance and stronger alignment with COSHH compliance.
Key options to consider include:
Ventilated cabinets – help reduce vapour build-up
Colour-coded cabinets – improve clear identification (e.g. yellow for flammables)
Underbench cabinets – space-saving storage close to the point of use
Type 90 COSHH storage cabinets are widely used in higher-risk environments where stronger fire protection is required to meet safety and compliance standards.
The Benefits of Certified Fire Safety Cabinets
Certified fire safety cabinets are important under COSHH requirements because they provide clear, testable evidence that hazardous substances are being stored safely. A certified DENIOS cabinet helps demonstrate compliance during inspections and supports safer day-to-day handling of flammable liquids.
A few COSHH-relevant benefits include:
Documented fire resistance performance (30–90 minutes) - proven protection to safeguard escape routes and limit fire spread
Supports workplace inspections and insurance requirements - provides clear evidence of compliant COSHH storage
Self-closing doors - reduce the risk of human error and improve fire containment
Integrated spill containment (sump) - supports COSHH secondary containment requirements
Corrosion-resistant materials - suitable for demanding industrial environments and chemical exposure
Clear segregation options - help safely separate incompatible hazardous substances
Tested seals, joints, and closing mechanisms - ensure reliable performance during fire conditions
Durable industrial construction - designed for long-term use in workshops, laboratories, and production sites
When combined with EN 14470-1 certification, these features provide strong assurance that COSHH storage cabinets are meeting both safety expectations and regulatory requirements in real workplace conditions.
The New Generation of Flammable Storage
Modern Design & Colour-Coded Safety Integration
Modern COSHH storage cabinets combine certified safety with practical workplace design. Available in seven door colours, cabinets can be matched to existing safety coding systems, making it easier to identify different chemical classes and reduce handling errors in busy laboratories and industrial workspaces.
Flexible Sizes for Every Workplace
Available in 60, 90, and 120 cm widths, these cabinets are designed to fit a wide range of environments, from compact labs to larger production areas. Their dimensions also allow easier transport and installation, with models designed to pass through standard doorways using pallet trucks during relocations or site changes.
Improved Access for Safer Chemical Handling
Modern cabinet layouts are designed to improve ergonomics and day-to-day handling of hazardous substances. Options such as pull-out drawers provide better visibility and easier access to smaller chemical containers, helping reduce strain, spills, and handling risks during use.
Expert Support for Complex Storage Needs
For workplaces storing large numbers of small containers or mixed hazardous substances, drawer systems can offer more efficient organisation than fixed shelving. Pull-out storage also improves visibility and supports safer handling during frequent access.
FM Certified Storage
EN 14470-1 is the recognised European standard for COSHH storage cabinets, but if your workplace follows American standards such as NFPA or OSHA, FM-approved cabinets are often the preferred option.
FM testing requirements include:
Double-wall steel construction with a 38 mm air gap
2-point locking systems
A minimum sump depth of 51 mm
Flame arrestor vents
A maximum internal temperature threshold over a 10-minute test period
FM-certified flammable storage cabinets are designed to provide durable, reliable storage for hazardous substances and are widely recognised in industrial environments operating to US safety standards.
Compact and Small-Format Flammable Cabinets
Compact COSHH storage cabinets are ideal for workplaces with limited space, fitting easily under benches or extractor hoods while still providing certified protection for flammable liquids.Â
They are commonly used in laboratories, workshops, and industrial environments where hazardous substances need to be stored safely close to the point of use.
These smaller units typically include:
Adjustable shelves - allow flexible storage of different container sizes, helping improve organisation and reduce the risk of unstable storage.
Integrated spill containment sump - captures leaks or spills inside the cabinet, helping support COSHH secondary containment requirements and preventing contamination of surrounding work areas.
Automatic fire-triggered door closing - helps contain fire and reduce oxygen supply if temperatures rise, improving safety during an emergency.
Compact footprint with certified fire protection - provides the same level of protection as larger cabinets while saving valuable floor space in smaller work areas.
Ventilation for Flammable and Hazardous Substance Cabinets
COSHH requires employers to prevent or control exposure to hazardous vapours, making ventilation an important part of safe chemical storage. Without proper airflow, vapours from flammable liquids and hazardous substances can build up inside storage areas, increasing the risk of inhalation, fire, or explosive atmospheres.
When is ventilation required under COSHH?
If hazardous vapours can accumulate during storage or normal use, employers must take steps to control exposure and reduce risk to employees. This is particularly important in laboratories, workshops, manufacturing environments, and other enclosed workspaces where flammable substances are handled regularly.
Ventilated COSHH storage cabinets help:
Reduce vapour build-up inside the cabinet
Lower inhalation risks for employees
Improve overall workplace safety
Help prevent the formation of explosive atmospheres
Support compliance with COSHH exposure control requirements
The New UFA 2.0 Recirculating Filter Module
For many workplaces, ducting is impractical. COSHH doesn’t specify whether extraction must be ducted or filtered - it only cares about effectiveness.Â
The UFA 2.0 recirculating air filter attachment satisfies that requirement with calibrated VOC sensors and continuous airflow monitoring, giving you measurable proof of exposure control.

FAQs
COSHH regulations do not specifically state that a cabinet must be used, but employers are legally required to store hazardous substances safely and control associated risks. In many workplaces, COSHH storage cabinets are the most effective way to meet these requirements for flammable or hazardous chemicals.
Flammable storage cabinets are designed for substances such as solvents, fuels, paints, aerosols, and other flammable liquids. The suitability of a cabinet depends on the type and volume of chemicals being stored, so it is important to check Safety Data Sheets (SDS) and risk assessments before use.
Ventilation may be required where hazardous vapours could build up inside the cabinet or the surrounding workspace. Ventilated COSHH storage cabinets help reduce inhalation risks, improve workplace safety, and support compliance with COSHH exposure control requirements.
Type 30 cabinets provide 30 minutes of fire resistance and are generally used in lower-risk environments with smaller quantities of flammable substances. Type 90 cabinets provide 90 minutes of fire resistance and are typically used in higher-risk workplaces such as laboratories, workshops, and manufacturing facilities.
