Battery Energy Storage Systems Q&A

Описание: Join ORR Protection experts Lee Kaiser and Aaron Wille as they discuss battery safety and fire suppression systems for battery energy storage systems, like those found in data centers.

0:00 Welcome from Lee Kaiser
0:40 Does NFPA 855 apply to the data center environment?
2:43 Which sections of NFPA 855 refer to data centers?
3:37 How does UL9540A apply to data centers?
7:13 What should an end-user look for in the UL9540A listing and large-scale fire test report?
12:10 Is a lithium battery fire a self-sustaining fire and can thermal runaway be avoided by simply breaking the fire triangle?
16:44 Where can one find the appropriate sprinkler density for different batteries or technologies?
19:56 What are some examples of listed devices or approved methods to detect and minimize thermal runaway?
21:16 Does Li-ion tamer utilize off-gas detection instead of the typical heat detection in battery management systems?
22:59 Can battery management and UPS systems be integrated into the fire alarm system?
25:20 What is the recommended best-practice for a fire department first responder in a Lithium-ion battery fire situation?
30:32 What are some alternatives that can better our response to Bess fires?
33:04 Are there any clean agents capable of suppressing a Lithium-ion battery fire?
35:30 What are some other alternatives to suppressing a battery fire other than sprinkler systems and clean agents?
38:26 What’s required to meet NFPA 855 if users are going to put Lithium-ion batteries in their new-construction data centers?
45:36 Which level of gas detection would typically turn the emergency exhaust fan on?
46:30 LEL is the only form really required by NFPA 855, not necessarily off-gas detection?
47:00 What are some of the biggest challenges of data centers moving from Lead-acid to Lithium-ion battery storage?
51:45 In data center environments with distributed UPS, how is the fire protection and suppression design affected and how is that affected by NFPA 855 requirements?
56:22 How do we dispose of batteries that have gone through thermal runaway?
