Mostly through reduced manual handling and fewer site visits. Manual handling of large lead-acid monoblocs is a recognised musculoskeletal injury exposure for maintenance crews, and a lithium bank of equivalent usable energy is a fraction of the weight and volume. Front terminal formats remove reaching across live terminals on upper tiers. And maintenance-free or very-low-maintenance systems with remote monitoring cut the number of trips to remote and difficult-to-access locations, which removes driving exposure, usually the largest single risk in remote site work. Note that where hazardous-area or Ex requirements apply, that is a separate specification conversation to have early.
