New partner research report available: UL 9540A Installation Level Tests with Outdoor Lithium-ion Energy Storage System Mockups
Led by our partners in UL Fire Research and Development,this report涵盖进行的实验结果，以获得来自热失控的火灾和燃烧危险的数据及其通过能量存储系统（ESS）传播。UL 9540A测试标准在电池，模块，单元和安装水平下提供了对热失控和在能量存储系统中的传播的系统评估。来自该测试的数据可用于设计安全选址和安装所需的火灾和爆炸保护系统。该项目团队由UL研究工程师亚当·巴罗和AlexKlieger和UL FSRI研究工程师Mark McKinnon和Jack Regan领导。
In addition to temperature, pressure, and gas measurement instruments installed inside of the container, fire service portable gas monitors were placed at locations inside and outside the storage container during the experiments to assess their ability to detect products of thermal runaway and inform fire service size-up decisions. Review section 2.2.3 Fire Service Size-up Equipment to learn more.
This research demonstrates a clear need for responding firefighters to have early access to data from instrumentation installed within an ESS, particularly gas measurement instrumentation, available through a monitoring panel. Additionally, it highlights the importance of communication between responding firefighters and personnel responsible for management of the ESS, who can aid in complete evaluation of system data to develop a more clear picture of system status and potential hazards.
Tactical considerations for the fire service include:
- Thermal imaging cameras do not enable evaluation of the number or location of ESS units in thermal runaway.
- Thermal imaging cameras enable a limited ability to determine whether a suppression system has operated or is operating.
- Thermal imaging cameras are not a viable tool for determining the nature of visible vapors (e.g., battery gas, steam, Novec 1230, etc.)
- First responders should consider the practicality of continuous monitoring of the interior and exterior gas environment.
- Gas meters and visual observations should be utilized for defining the hot zone or exclusion zone at ESS incidents.
- Full structural PPE (Level D ensemble) with full SCBA should be donned before performing size-up or operating within the hot zone.
- 便携式煤气表具有有限的有效性，可评估ESS容器内的爆炸性氛围的潜力。
- Fire service portable gas meters have limitations in a battery gas environment.
- Ventilation of an ESS installation may result in a deflagration or rapid transition to flashover.
