98 HAZARDOUS SUBSTANCES CABINETS - DIN EN 14470-1 Hazardous substances may only be stored in workrooms if storage is compatible with the protection of workers and is carried out in special facilities! Safety cabinets for flammable liquids as per DIN EN 14470-1 Fig.: SiS Type 30 / 1200 GL (≥ 30 minutes - type-approved) The classification of fire resistance was set to 4 types: Type 15 = ≥ 15 minutes* Type 30 = ≥ 30 minutes Type 60 = ≥ 60 minutes Type 90 = ≥ 90 minutes As in Germany safety cabinets type 15 minutes are not approved and safety cabinets types 30 minutes and 60 minutes are only of limited use, in Germany safety cabinets are confirmed with a fire resistance of 90 minutes (type 90) as a state of the art. In many other European countries, however, is due to lack of legal regulations, the use of other type classes is also possible. That is why we also have low-class hazardous materials cabinets in the delivery program (for example type 30 = ≥ 30 minutes). * deleted by revised version DIN EN 14470-1 : 2023 ◆ Construction and testing of safety cabinets: ◆ The type examination of the entire cabinet construction area in a fire chamber of an independent materials testing institute (flame impingement) is in accordance with European standard test conditions. Deviations without comparative tests are limited to a reduction in height and width to a maximum of 100 mm and reduction in the depth of 150 mm. q q Protective goals: ◆ Sufficient escape time for the employees in the working area. Firefighters and rescue teams must have a plenty of time to get into the working area before the hazardous substances stored in a safety cabinet turn a small erasable fire into an uncontrollable one. q q PRACTICAL INFORMATION 6 Development and construction Examination by an independent materials testing institute Approval / certificates
