Reliable protection in case of fire

What do I need a safety storage cabinet for?

When handling hazardous substances, the utmost care is essential. Our technology with maximum fire resistance helps you to achieve this. Thanks to their special design, our safety storage cabinets guarantee 90 minutes of fire resistance, type-tested in compliance with DIN EN 14470-1.

DÜPERTHAL safety storage cabinets with Type 90 fire resistance rating allow sufficient time for workers to leave the room in the event of a fire and allow fire fighters sufficient time to get into the laboratory. All of this before a small and extinguishable fire from stored flammable substances can cause an uncontrollable fire. The cabinet is tested under fire conditions as standard. Each cabinet model is type-tested in a fire chamber in accordance with DIN EN 14470-1.

90 minutes – Development and timeline of a fire

Start of fire

The fire alarm is activated.
Evacuation of employees begins

5-10 min after start of fire

Employees are outside the danger zone
The fire brigade is on the way to the site

10-15 min after start of fire

The fire brigade is at the source of the fire
Safety storage cabinets with a fire resistance of only 10 minutes stop working at this point
The flammable substances are no longer safety stored
The fire brigade has to fight the fire with a considerably increased risk
Increased damage can be expected

90 min after start of fire
Advantages of 90-minute technology for you

Type 90 safety storage cabinets continue to function for 90 minutes.
The critical hazardous substances are stored safely for at least 90 minutes.
The fire brigade has considerably more time to extinguish the fire safely.
Reduction of the fire load and minimisation of damage.

DÜPERTHAL SAFETY CABINET TYPE 90 IN EXTREME TEST

How does a safety storage cabinet work?

Fire chamber test in accordance with DIN EN 14470-1

The fire resistance rating of safety storage cabinets in accordance with DIN EN 14470-1 is determined by the rise in temperature of the cabinet interior inside a fire chamber, based on the temperature/time curve set out in DIN EN 1363-1. Based on an initial temperature of 20 +/- 5 °C and the time it takes for the temperature in the cabinet interior to reach max. 180 °C, the cabinet is then classified as Type 30, 60 or 90 (corresponding to the time in minutes). Safety storage cabinets for pressurised gas cylinders complying with DIN EN 14470-2 are subjected to a comparable test, see here for details.

Your technical advantage

US standards in accordance with FM/UL, NFPA 30

Max. permissible temperature in cabinet in accordance with FM/UL = 163 ° (325 °F).
Temperature profile in accordance with NFPA 251 in the open fire chamber.
Example of the rising temperature in an FM/UL cabinet during the fire test, monitored with 1 thermometer.

European standard DIN EN 14470-1

Max. permissible temperature in cabinet in accordance with DIN EN 14470-1 = 200 °C (392 °F).
Temperature profile in accordance with DIN EN 1363-1 in the closed fire chamber.
Example of the rising temperature in a Type 90 cabinet during the fire test, monitored with 11 thermometers.

Your economic advantage

90 minutes of safety thanks to special design

The doors and the outer carcass are made of powder-coated sheet steel.

The inner carcass and the inside of the doors are made of high-quality decor panels.
There is a special insulation between the inner and outer carcasses, so that the heat cannot penetrate into the cabinet interior in case of fire.
In case of fire, doors, drawers and ventilation openings for the air supply and exhaust air are automatically closed and the door gaps as well as open joints are sealed by foam-forming seals.

Benefits of DÜPERTHAL safety storage cabinet Type 90 to you

Chain reactions are avoided in case of fire.
Workers, the fire brigade, and rescue services will be protected.
Maximum fire protection for buildings and systems.
Reduction of insurance contributions for fire protection is possible.
Financial security, e.g. by reducing the risk of default of production and buildings.
Meets the requirements for risk management in accordance with ISO 9000 and ISO 14001.
Use of High Quality safety storage cabinets conserves resources and strengthens the image of your company.

Test criteria, protection objectives and minimum requirements

The three essential requirements for a safety storage cabinet in accordance with DIN EN 14470-1 are minimisation of the risk of fire, minimisation of fumes released into the work environment, and retention of possible leakages. The test requirements of the laboratory furniture standard DIN EN 14727 or the new DIN EN 16121 and DIN EN 16122 also guarantee a minimum level of quality.

Extracts from DIN EN 14470-1

Ventilation

To prevent an explosive atmosphere, the ventilation must be effective directly above the bottom tray.
Ventilation openings for air supply and exhaust air must automatically close themselves when the temperature reaches 70° C.

Interior fittings

The bottom tray, which is used to retain potential leakages, must still be functional after the fire resistance test.
The shelves must be made of non-absorbent material, must hold the permissible load over the duration of the fire and must be a maximum of 1.75 m above the floor.

Door technology

Complete self-closing of the doors within a maximum of 20 seconds; an arrest system with temperature release at 50 ° C available as an option.
The closing force between the main closing and opposite closing edge of the door must not exceed 100 Newtons.
It must be possible to operate each wing of the door with one hand.
If the doors are lockable, the locking mechanism must not prevent self-closing in the event of fire.

Fire chamber test

Each cabinet model and size is type-tested in a fire chamber in accordance with DIN EN 14470-1 Type 90.

Static endurance test

Standing surfaces, e.g. storage shelves, are subject to a static load and impact test and must not show any signs of breakage or other damage.

Dynamic load test

All components that move mechanically such as pull-out shelves, drawers and doors are tested with 50,000 or 80,000 cycles each. After the tests, the doors must close precisely and engage securely.
