Abstract: High-energy capacitor banks may have a significant amount of residual energy after a test or malfunction. This presents distinct hazards from shock, arc flash, projectile, and lung/ear/eye when the capacitor bank is to be manually rendered safe. Although standard operating procedures address most of these hazards, the danger to the ear and lung from the over-pressure of an arc blast has not been satisfactorily established. This lung and ear danger is addressed in this report, along with proposed mitigation techniques.
