The Pi has lots of capacitors, all of which can potentially hold some charge. As to whether enough to be a problem with your 'explosive gas sterilisation process' I have no idea.

I have a basic question about the Raspberry Pi Zero W regarding if this part can be sterilized. The main question I have is if the Raspberry Pi Zero W holds a charge (has a capacitor or something similar). The sterilization method in question uses explosive gas, so it is import that the Raspberry Pi Zero W cannot in anyway cause an ignition.
Thanks for your help!
Wikipedia's comments on ethylene oxide are simply wrong in some clinical regards:Heater wrote: ↑Sat Mar 23, 2019 7:20 amAccording to wikipedia Ethyle oxide is often used for sterilization of electronics:
"Ethylene oxide is one of the most commonly used sterilization methods in the healthcare industry because of its non-damaging effects for delicate instruments and devices that require sterilization, and for its wide range of material compatibility. It is used for instruments that cannot tolerate heat, moisture or abrasive chemicals, such as electronics, optical equipment, paper, rubber and plastics"
Not that it would not be wise to test for adverse effects.
Just autoclave it. Pi can take 120C for twenty minutes
Code: Select all
As a toxic gas that leaves no residue on items it contacts,
Ethylene oxide is one of several tools in the medical trade for killing bugs but must be used with great care for patient and handlers alike."... ethylene oxide itself is a very hazardous substance. At room temperature it is a flammable, carcinogenic, mutagenic, irritating, and anaesthetic gas.
And others of the same name working in bio-engineering and medical fields.
What information?...this information although only in specific uses could be invaluable.
Please...not "sterilizing" but "disinfecting". Sterilizing means NO viable bugs. Disinfecting means "few", but not the same as "Sterile".

Miles OT in the meantime.
If they want to use ethylene oxide or chlorine dioxide the question the TO asked was: Is there a risk for electronic discharging? Answer: no, 10 sec after powering off (by jdb » Fri Mar 22, 2019 4:23 pm)
The remaining posts (including my) are not helpful at all. People having equipment for ethylene oxide sterilization typically know what they are doing...
