Don’t do this unless it is necessary
Keep one hand in your pocket
Use proper insulated shoes
Don’t touch any wires or metallic parts unless you have to. All metallic parts should have been grounded when it was built, but the ground may be missing.
If you have to touch something, turn off all power first, and wait for any caps to discharge. Use only one hand. You did put discharge resistors across all the HV caps?
Make sure someone else is nearby when you do this.

First be sure that the input power supplied to the device is OFF.
Keep at a distance (do not touch) from the device, as you turn the power on, and while it it is turned on.

This is the number you need. Under a relative humidity of about 40%, the minimum voltage required to produce a spark is
30 kV/cm
which means that at a distance of 1 cm there will be an arc if the voltage is more than 30kV, there will be a spark in air. So, make sure that is not you. This value changes dramatically with the relative humidity so if you are in Florida, be aware cause it will be lower.
Make sure that you are properly insulated and NOT grounded; you don’t want to become a short path for the high voltage to ground. There should be a properly grounded metal rod around so that if there is an accidental surge of high voltage, it goes there and not through you. Having a wire that directly connects to water piping is a good thing to have close by.

Outlets
Check for outlets that have loose-fitting plugs, which can overheat and lead to fire. Replace any missing or broken wall plates. Make sure there are safety covers on all unused outlets that are accessible to children.
Cords
Make sure cords are in good condition—not frayed or cracked. Make sure they are placed out of traffic areas. Cords should never be nailed or stapled to the wall, baseboard or to another object. Do not place cords under carpets or rugs or rest any furniture on them.
Extension Cords
Check to see that cords are not overloaded. Additionally, extension cords should only be used on a temporary basis; they are not intended as permanent household wiring. Make sure extension cords have safety closures to help prevent young children from shock hazards and mouth burn injuries.
Plugs
Make sure your plugs fit your outlets. Never remove the ground pin (the third prong) to make a three-prong fit a two-conductor outlet; this could lead to an electrical shock. NEVER FORCE A PLUG INTO AN OUTLET IF IT DOESN’T FIT. Plugs should fit securely into outlets. Avoid overloading outlets with too many appliances.
Ground Fault Circuit Interrupters (GFCIs)
GFCIs can help prevent electrocution. They should be used in any area where water and electricity may come into contact. When a GFCI senses current leakage in an electrical circuit, it assumes a ground fault has occurred. It then interrupts power fast enough to help prevent serious injury from electrical shock. Test GFCIs according to the manufacturer’s instructions monthly and after major electrical storms to make sure they are working properly. Replace all GFCIs that are not working properly, but never replace a GFCI with a standard non-GFCI outlet or circuit breaker. Do not use an appliance or device that trips a GFCI on a nonGFCI-protected circuit; instead, take the appliance to authorized repair center to be checked for faulty wiring or replace it.
