What is the purpose of storing flammable hazardous substances in safety storage cabinets? By storing flammables in safety cabinets with a defined fire resistance, the basic safety requirements for fire load minimisation are fulfilled. Safety cabinets must be designed, installed, operated and maintained in a way that guarantees the safety of employees and third parties. What are the advantages of storing in safety storage cabinets? Safety storage cabinets with a fire resistance of 90 minutes are considered a separate fire compartment. Thus, storage in these cabinets offers the following advantages: ››› Fire and explosion protection requirements are met. The use of safety cabinets is also recommended for small quantities of flammable liquids! ››› Easy and flexible installation in workrooms. ››› Reduction of in-house transport of hazardous substances and the associated risks. ››› Installation in corridors is possible after consultation with the local fire brigade, provided the width of the escape route is observed. What types of safety storage cabinets are there? There are three types: 1. Fire-resistant storage cabinets for flammable liquids: Safety storage cabinets according to EN 14470-1 for the storage of flammable and combustible liquids, solid hazardous substances, compressed gas cartridges and aerosol dispensers. 2. Fire-resistant storage cabinets for compressed gas cylinders: Safety storage cabinets in accordance with EN 14470-2 for the storage of pressurised gas cylinders, pressurised gas cartridges and aerosol dispensers. For more information, see the corresponding chapter from p. 240. 3. Fire-resistant safety cabinets for lithium-ion batteries: Safety storage cabinets, at the moment without normative reference, for the storage and charging of lithium-ion batteries. For more information, see the corresponding chapter from p. 230. How are safety storage cabinets classified? Safety storage cabinets are classified according to their fire resistance in a fire chamber test as follows: RESPONSIBLE STORAGE IN SAFETY STORAGE CABINETS Type of safety storage cabinet Measured time for temperature rise in the fire chamber test Safety storage cabinet for flammables* EN 11470-1 Safety storage cabinets for compressed gas cylinders** EN 14470-2 Safety storage cabinets for lithium-ion batteries*** 30 minutes Type 30 G 30 - 60 minutes Type 60 G 60 - 90 minutes Type 90 G 90 90 * Flammable liquids: Measured time for temperature rise by 180 K, measured inside the cabinet ** Compressed gas cylinders: Measured time for the temperature rise by 50 K, measured on the surface of the gas cylinder valve holder *** Lithium-ion batteries: Measured in accordance with EN 1363 and EN 14470-1 State of the art Safety storage cabinets with a certified fire resistance of 90 minutes are designated as state of the art. As a result, they are considered a separate fire compartment or storage section. Please observe local legislation and regulations. 28 Flammables
