Static Dissipative is defined in ohms resistance to charging:
- Anything less than 1 x 10e6 ohms is considered Conductive.
- Anything above 1x10e12 ohms is considered Insulative.
- Anything between these two points is considered Static Dissipative.

How do electrostatic wrist straps work?
How Does It Work. A static discharge from you travels to the wrist strap from a direct connection to your skin. That discharge then follows a path from the wrist strap to the cord and so on until it reaches ground and is safely dissipated.
What is the purpose of the ESD wrist strap?
An anti-static wrist strap is a key piece of safety gear that helps to prevent the buildup of static electricity near sensitive electronics or other projects where static charge could damage electronics or cause safety issues. The wrist strap is often used with an anti-static mat or other type of work space covering.

The Short Answer is yes, anti-static mats and wrist straps protect your computer components from getting a static shock from your body, which can result in damaging one of your components like RAM, CPU, and Motherboard.
Where do you clip anti static wrist band?
attach wrist strap clip to the metal rim of the case while as weaselman said "make sure the cord is plugged into the PSU, and the plug from the power lead is plugged into the wall socket ,but is turned off at the wall socket switch, to give you a good ground."
How do anti static bars work?
Simco-Ion anti-static bars generate an electrical field which causes the air molecules in the vicinity of the bar to break down into positive and negative ions. Because opposite charges attract, any charged material passing near the bar will attract ions until the charge on the material is neutralized.
How do I ground myself for static?

Can you build a PC while standing on carpet?
I don't have a good desk/table for building on so built on the living room floor on the carpet with the pc stood on the polystyrene packing the case came in. It worked without issue. I just try not to move too much on the carpet and kept touching the psu case. I've built/upgrade countless times using similar approach.
Do you need 2 anti static wrist strap?
If you are concerned about touching parts with your other hand, then the body conductivity will provide discharge path for the entire body even with one wrist strap. So the answer is "YES".
What happens if an ESD fails?
In the case of a latent failure, the ESD event can damage a device and it will show no signs of defect and continue to function normally until it is too late to repair or replace. If this damage goes undetected, the lifespan of the device can be shortened resulting in premature failure.
How many volts does an ESD discharge?
It typically takes an ESD discharge of more than 2,500 to 3,500 volts for a person to feel a shock, however, a small discharge of 25 volts can damage electronic components without the engineer feeling a thing.
Why is it important for NASA engineers to use proper precautions when working with ESD sensitive hardware?
It is essential that NASA engineers use proper precautions when working with Electrostatic Discharge (ESD) sensitive hardware, as poor ESD control practices could be the difference between success and failure for a mission. ESD control is a fundamental component of NASA’s workmanship policy, which is why NASA requires operators to verify ESD personnel grounding systems (e.g. wrist or heel straps that are continuously connected to common point ground) are properly functioning before they enter an ESD Protected Area (EPA) or come within one meter of an ESD sensitive item.
Can you use a wireless wrist strap in ESD?
Wireless wrist straps do not meet American National Standards Institute (ANSI)/ESD S20.20 Wrist Strap System performance requirements and therefore are not acceptable for use in ESD controlled areas used to process critical NASA mission hardware.
Do wireless wrist straps drain charge?
According to results from testing performed by the NASA Interagency Working Group on Electrostatic Discharge (IAWG-ESD), it was confirmed that wireless wrist straps failed to prevent charge build up or to drain accumulated charge in order to prevent potential discharges.
How to use ESD mat?
Determine what size of ESD mat you need for good surface coverage at your workspace. Once the mat arrives, clear the work surface of objects and clean it with a clean, dry cloth or paper towel. Place the mat onto the work surface and plug the mat’s grounding connector into the wall socket.
What are the two essential items that are needed to protect electronics?
To create a professional and safe work environment for electronics, one must have two essential items: an ESD mat and an ESD wrist strap . These are the items that can protect electronics from damaging electrostatic discharge.
Why is it important to get rid of static electricity?
For instance, pulling apart socks stuck together may cause sparks to pop from friction.
What is an anti static wrist strap?
An anti static wrist strap is worn by the user and in essence gives a way for a static discharge to leave you and safely discharge to the ground. The wrist strap is often a bright color, easily seen by others and a good visual reminder to the user. The wrist strap should be comfortable and fit snug to allow a proper connection.
Why is it important to wear wrist straps?
By wearing your wrist strap you’ve taken one major step towards preventing a damaging static discharge. You also set the tone as a professional for your peers, manager and anyone who may report to you.
What does a brightly colored wrist strap mean?

How many volts does an ESD floor generate?
Generally less than 50 and with some ESD floors you'll only generate 2 or 3 volts! NOTE: It's important to wear a heel strap on each foot! When walking one heel is not touching the grounded floor (or mat) hence the charge needs to be dissipated by the other foot that's making contact.
How is static electricity generated?
