As of the end of 2021, the cumulative installed capacity of new energy storage globally reached 25.4 GW, with LIB energy storage accounting for 90% (CENSA, 2022). However, the number of safety incidents such as fires and explosions in lithium-ion BESSs has been rapidly increasing across various countries in the world.

Of interest is noting that two different documents describe the hazard levels in distinct ways. In the SAE J2464 manual [6] the rupture hazard is in position 5 while flame is in position 6. In the case of the older EUCAR documentation and the SAND2005 report [5], [7], these two positions are interchanged, and moreover there are differences

Two approaches, Hazard and Operability Analysis and System Theoretic Process Analysis, were used to evaluate hazards associated with automotive rechargeable energy storage systems (RESSs). The analyses began with
Potential Hazards and Risks of Energy Storage Systems The potential safety issues associated with ESS and lithium-ion batteries may be best understood by examining a case involving a major explosion and fire at an energy storage facility in Arizona in April 2019, in which two first responders were seriously injured.
In the last few years, the energy industry has seen an exponential increase in the quantity of lithium-ion (LI) utility-scale battery energy storage systems (BESS). Standards, codes, and test methods have been developed that address battery safety and are constantly improving as the industry gains more knowledge about BESS.

There has been a dramatic increase in the use of battery energy storage systems (BESS) in the United States. These systems are used in residential, commercial, and utility scale applications. Most of these systems consist of multiple lithium-ion battery cells. A single battery cell (7 x 5 x 2 inches) can store 350 Whr of energy.
1. Introduction Lithium-ion batteries (LIBs) have raised increasing interest due to their high potential for providing efficient energy storage and environmental sustainability [1].LIBs are currently used not only in portable electronics, such as computers and cell phones [2], but also for electric or hybrid vehicles [3]..
To the best of the authors'' knowledge, there is a lack of studies focusing on system safety/hazard analysis of large-scale EES systems beyond batteries, despite the significant highly localized concentration of energy involved.
A Lithium-Ion battery fire presents multiple hazards including fire damage to buildings and personnel, gas release, chemical damage and reactions, and hazardous material contamination. Containers/ infrastructure for BESS must be clear of vegetation, including grass, for at least ten (10) metres on all sides.
Reports of fire incidents highlight the criticality of battery safety, particularly unpredictable thermal runaways in EVs [17] and grid-scale storage [18, 19]. In recent times, thousands of EVs across major companies were recalled due to safety concerns [ 20 ], incurring costs estimated in the tens of billions to mitigate hazards [ 21 ].
