WikiHow has a fairly comprehensive and detailed set of steps that can be taken to help ensure that you are grounded and that there is not a harmful discharge of static electricity while working on electronics. You can view this information at https://m.wikihow.com/Ground-Yourself
You’ll notice that there are two methods discussed however “method one” most directly applies to the question originally posted by mayer. I have included the 13 steps (in total) that make up both methods. If You view the link provided you will also notice that there is more detailed information available about each of these steps with illustrations provided as well! Here are the headings/titles for the steps described (taken directly from WikiHow):
“Method One of Two:
Working With Computers and Electronics
# Set up your workspace in an area without rugs or carpet.
# Keep pets away from your workspace.
# Work in an environment with humidity levels between 35 and 50 percent.
# Remove trash and other unnecessary items from your workspace.
# Touch a grounded object before starting work on your computer or electronic device.
# Wear an anti-static strap or wristband.
# Stand on an anti-static mat when working on your device.
# Verify your computer is unplugged or turned off before working on its components.
# Handle all components by their edges when installing and removing them from your machine.
Method Two of Two:
Grounding Yourself Using General Techniques
# Increase humidity levels in your environment.
# Avoid wearing clothing made from wool and synthetic fabrics.
# Keep your skin and hands moisturized.
# Touch a metal object using another metal object to release static discharge.”
Another tip is included about preventing damage to electronics and computer parts by storing them inside anti-static bags to mitigate any damage from encounters with static charges during handling, transportation or storage etc.
So far everyone has been pretty spot on and I’ve probably ever seen professionals utilize the anti-static grounding straps/ wristbands. (Never heard of it before but this site https://m-us.gearbest.com/tool-kit/pp_1697094.html?wid=1433363¤cy=USD&vip=14752947&gclid=EAIaIQobChMI_v-M6u6P3gIVBIGzCh193gzBEAkYDCABEgJ8vfD_BwE sells a common wrist strap for $1.70 + “free shipping, (and) no tax”
They make disposable versions and they make real fancy versions too!
