[CentOS] OT: high static in server room

Thanks all for the reply.
What is the worst thing can happen from excessive static?
We have two corrupted UEFI when we reboot servers which now I suspect
because of static.
Yesterday I actually saw a spark when I put a memory module on
motherboard even though I was careful like touching the metal casing
first. That just blow my mind and made me ask you in this list.
