Small capacitors can become shrapnel hazards if explosion occurs.
Electric arcs can generate temperatures up to 35,000 degrees Fahrenheit. Internal failure of one capacitor in a bank may result in an explosion when the other capacitors in the bank discharge into the failed capacitor. Older fluids contain PCBs Capacitors can be Dangerous when you Least Suspect Capacitor with terminals shorted to metal case. Induced charge Movement of an improperly grounded capacitor in a high intensity magnetic field can cause it to charge See dielectric absorption below Large capacitors are heavy, awkward, and may be difficult to lift for maintenance. High voltage cables should be treated as capacitors since they have the capability to store energy Knowledge of any electrical system is essential prior to working with it Dielectric Absorption Absorption of a charge by the dielectric when subjected to an electric field other than normal polarization or charging.
