德国德安DENIOS符合EN 14470-1欧洲防火安全柜存储标准

2023-12-07 10:52

任何在工作场所储存易燃液体的人都应使用符合 EN 14470-1 标准的安全柜。该欧洲标准自2004年起生效,规定了用于在工作场所存放易燃液体的防火安全柜的结构要求和测试条件。如果您选择DENIOS系列中的防火安全柜,您可以确信它已通过EN 14470-1测试并符合所有相关要求。


Anyone who stores flammable liquids at the workplace should do so in safety cabinets tested to EN 14470-1. The European standard has been in force since 2004 and regulates the structural requirements and test conditions for fire-protected safety cabinets for the storage of flammable liquids in workrooms. If you opt for a safety cabinet with fire protection from the DENIOS range, you can be confident that it is tested according to EN 14470-1 and meets all the relevant requirements.


但是,EN 14470-1 到底是什么呢?危化品存储柜必须通过哪些负荷测试才能为您的企业提供更高的安全性?还请往下看~

But what exactly is EN 14470-1 and which load tests does a hazardous materials cabinet have to pass before it can provide added safety to your business? We have summarized it for you here!


即使在极端情况下也能保证安全额耐火存储安全柜



易燃液体——例如溶剂、润滑剂和油漆——在实践中被广泛使用。然而,在某些条件下,它们可能与空气形成易燃混合物。严格来说,危险的不是液体本身,而是其散发出的气体和蒸汽。如果外部热量达到闪点,就会导致严重后果。从潜在的危险来看,工作场所在没有任何保护措施的情况下储存易燃液体是极不负责任的行为。工作区域的风险必须降至最低。欧洲标准描述了用于在正常室温下密闭容器中储存易燃液体的安全柜的设计和测试标准,包括三个主要安全要求:最大限度地减少火灾风险和在发生火灾时,已知(经过测试)的最短时间内保护柜内物品(耐火等级)以及最大限度地减少释放到工作环境中的蒸汽以及控制柜内可能的泄漏。


Flammable liquids - such as solvents, lubricants and paints - are widely used in practice. Under certain conditions, however, they may form flammable mixtures with the air. Strictly speaking, it is not the liquid itself that is dangerous, but the gases and vapors emitted by it. If the flash point is reached with external heat, it can lead to serious consequences. Judging from the danger potential, it would be almost irresponsible to store flammable liquids without any protection at the workplace. In work area in particular, the risk must be minimized. The European Standard describes the design and test criteria for safety cabinets used for the storage of flammable liquids in closed containers at normal room temperature and includes three main safety requirements: minimizing the risk of fire and protecting the contents of the cabinet in case of fire for a known (tested) minimum period of time (Fire resistance class) as well as the minimization of vapors released into the working environment and the containment of possible leaks inside the cabinets.

在实际操作中,用户可以根据耐火等级,在考虑到具体情况的前提下选择安全柜,使工作人员有足够的时间离开房间,也使消防人员有足够的时间在未经过的储存的可燃材料之前进入建筑物来防止发生无法控制的火灾。

In practice, the fire resistance class allows the user, taking into account the particular circumstances, to select a cabinet that gives the workforce ample time to leave the room, and gives the firefighters sufficient time to get into the building before passing through the stored combustible materials to prevent an uncontrollable fire.


90 分钟的安全柜:EN 14470-1耐火性能将安全柜最高级别


EN 14470-1根据耐火性能将安全柜分为4级。等级编号 - 15、30、60 和 90 - 代表安全柜在发生火灾时必须承受的最少持续时间(以分钟为单位)。在许多欧洲国家,耐火时间达到 90 分钟的安全柜是最先进的。例如,TRGS 510 等德国法规要求在工作场所中不受限制地储存易燃液体时必须具有最高的耐火性。TRGS 510 还根据这些 TRGS 轴承对安全柜进行了定义,并将耐火时间至少为 90 分钟的安全柜定义为储存区。另一方面,被归类为 30 分钟的安全柜只能在特定条件下使用。德国根本不允许使用 15 型安全柜。原则上,必须始终遵守各个欧洲国家的最低要求。此外,企业负责人的风险评估结果对于选择所需的耐火等级具有决定性作用。


EN 14470-1 divides safety cabinets into 4 classes according to their fire resistance. The class number - 15, 30, 60 and 90 - represents the duration in minutes that the safety cabinet must at least withstand in case of fire. In many European countries, safety cabinets with a fire resistance of 90 minutes are state-of-the-art. For example, German regulations such as the TRGS 510 demand the highest fire resistance for the unrestricted storage of flammable liquids in workrooms. The TRGS 510 also defines safety cabinets in the sense of these TRGS bearings and with a fire resistance of at least 90 minutes as a storage section. On the other hand, safety cabinets classified as Type 30 may only be used under certain conditions. Type 15 safety cabinets are not allowed in Germany at all. In principle, the minimum requirements in the respective European countries must always be observed. Furthermore, the result of the risk assessment of the responsible persons in the enterprises is decisive for the choice of necessary fire resistance class.

如果符合 EN 14470-1 的安全柜标有类型等级,制造商必须确保安全柜符合标准的设计要求,并通过测试条件中规定的防火测试。安全柜的耐火性由类型检验确定。在负载测试期间,根据EN 1363-1:1999,5.1.1的标准温度曲线,在火室中用火焰对柜体进行加热,并测量柜体内部的温升。根据指定测量点的内部温度达到最高180K所需的时间,安全柜被分为15、30、60或90型。此外,还要测试安全柜是否满足EN 14470-1的其他要求。其中包括:


If a safety cabinet according to EN 14470-1 is marked with the type class, the manufacturer must ensure that the cabinet meets the design requirements of the standard and has fulfilled the fire resistance test stated in the test conditions. The fire resistance of the cabinet is determined by a type examination. During the load test, the cabinet is heated with a flame in a fire chamber according to the standard temperature curve according to EN 1363-1: 1999, 5.1.1 and the temperature rise inside the cabinet is measured. Depending on the time that elapses until the internal temperature at one of the specified measuring points is max. 180 K, the cabinet is classified as type 15, 30, 60 or 90. It is also tested whether the cabinet meets the other requirements of EN 14470-1. This includes:


  • 自动关闭门:柜门必须从任何位置自动完全关闭。从触发时间起关闭时间不得超过20秒。如果安装了制动装置,则机柜前部附近的温度为 50 (+ 0 / -10) °C 时,门必须完全关闭。

  • Self-closing doors: The cabinet doors must close automatically and completely from any position. The closing time from the time of triggering may not exceed 20 seconds. If a detent is installed, the doors must fully close at a temperature of 50 (+ 0 / -10) °C in the vicinity of the front of the cabinet.
  • 自动关闭通风口:指定的供气和排气口在暴露于 70 (+/- 10) °C 的温度时必须自动关闭。

  • Self-closing vents: The specified openings for supply and extract air must close automatically when they are exposed to a temperature of 70 (+/- 10) °C.
  • 内部负载能力:安全柜的搁板和抽拉装置必须能够承受火灾期间制造商规定的最大负载。

  • Interior load capacity: The shelves and pull-outs of the safety cabinet must be able to withstand the maximum load specified by the manufacturer during the duration of the fire.
  • 功能性溢出托盘:为了保留泄漏物,最低层下方必须有一个底部托盘。其最小收集体积必须是柜内存储的所有容器的 10%,或至少是最大单个容器体积的 110%。接触火后,地板必须仍能正常工作。

  • Functional spill pallet: For the retention of leaks, a bottom tray must be present below the lowest level. Their minimum collection volume must be 10% of all vessels stored in the cabinet, or at least 110% of the volume of the largest single container. The floor pan must still be fully functional after exposure to fire.
