AI Customer ServiceOpen a window, aerate the room and have the board repaired. Eventually, you will die. But it's unlikely the capacitor will be the culprit Yes it's toxic; No it's not mercury; Yes you'll live :) If it was a "wet" capacitor type, then most likely that was sulfuric acid or some organic or inorganic solvent.
Is it safe to short (discharge) an AC capacitor before you remove it from the circuit. Or do you have to wait until after you remove it from the unit? Always short the capacitor as early into the disassembly process as you can.
Big capacitors (the kind most likely to be dangerous) are usually cylindrical and look roughly like battery cells. Assume they are charged until you've confirmed they are discharged. Use an appropriate tool to discharge and/or ground large capacitors, while keeping yourself well insulated and at a safe distance.
If they are chained serially and one fails open, then the capacitor won't discharge. If they are in parallel and one fails shorted, then you'll get a big spark when the capacitor discharges. Seems like you'd want both, like 2 parallel banks of 5?
To safely discharge a capacitor, the process is similar to charging the capacitor. The accumulated charges, which have opposite potentials and equal value, are stored in the capacitor when DC voltage (U) is applied to its terminals. The capacitance (C) and voltage (U) determine the charge (Q) stored in the capacitor.
Large value caps can recharge themselves from charge that is "hidden" in the electrolyte, and slowly percolates back onto the capacitor plates. If you remove the resistor, after a few hours you might discover (the painful way!) that the voltage has recovered to half what it was before you "fully discharged" the cap. Nice!
