battery work and the expected rarity of energized work has led to avoidance of necessary maintenance in some organizations and routine approval of EEWPs in others. This has led many to argue that EEWPs should not be required for battery systems [1, 4]. Battery risk assessment can be broken up into specific hazards.
Purpose: The purpose of this sample risk assessment is to provide installers of battery systems with a guide to carrying out a risk assessment for compliance with AS/NZS 5139. This sample is not a complete risk assessment and does not include on-site Safe Work Method Statements (SWMS) or Job Safety Analysis (JSA).

Rising EV battery demand is the greatest contributor to increasing demand for critical metals like lithium. Battery demand for lithium stood at around 140 kt in 2023, 85% of total lithium demand and up more than 30% compared to 2022; for cobalt, demand for batteries was up 15% at 150 kt, 70% of the total.
The costs of battery raw materials have been very volatile, and they reached an all-time high in 2022 because to supply imbalances during the recovery from Covid-19. This was the year they broke the previous record. Increasing battery manufacturing to satisfy the growing demand would not come cheap, which is another point to consider.
