Concept
Antistatic device
Summary
An antistatic device is any device that reduces, dampens, or otherwise inhibits electrostatic discharge, or ESD, which is the buildup or discharge of static electricity. ESD can damage electrical components such as computer hard drives, and even ignite flammable liquids and gases.
Many methods exist for neutralizing static electricity, varying in use and effectiveness depending on the application. Antistatic agents are chemical compounds that can be added to an object, or the packaging of an object, to help deter the buildup or discharge of static electricity. For the neutralization of static charge in a larger area, such as a factory floor, semiconductor cleanroom or workshop, antistatic systems may utilize electron emission effects such as corona discharge or photoemission that introduce ions into the area that combine with and neutralize any electrically charged object. In many situations, sufficient ESD protection can be achieved with electrical grounding.
Various symbols can be found on products, indicating that the product is electrostatically sensitive, as with sensitive electrical components, or that it offers antistatic protection, as with antistatic bags.
ANSI/ESD standard S8.1-2007 is most commonly seen on applications related to electronics. Several variations consist of a triangle with a reaching hand depicted inside of it using negative space.
Versions of the symbol will often have the hand being crossed out as a warning for the component being protected, indicating that it is ESD sensitive and is not to be touched unless antistatic precautions are taken.
Another version of the symbol has the triangle surrounded by an arc. This variant is in reference to the antistatic protective device, such as an antistatic wrist strap, rather than the component being protected. It usually does not feature the hand being crossed out, indicating that it makes contact with the component safe.
Another common symbol takes the form of a bold circle being intersected by three arrows. Originating from a U.S.

Static cling
Static cling is the tendency for light objects to stick (cling) to other objects owing to static electricity. It is common in clothing, but occurs with other items, such as the tendency of dust to be attracted to, and stick to, plastic items. In clothing, static cling occurs from static electricity. An electrostatic charge builds up on clothes due to the triboelectric effect when pieces of fabric rub against each other, as happens particularly in a clothes dryer. The separate positive and negatively charged surfaces attract each other.
Static electricity
Static electricity is an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, where the electric charge flows through an electrical conductor or space, and transmits energy. A static electric charge can be created whenever two surfaces contact and or slide against each other and then separated.
Electric spark
An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures. Michael Faraday described this phenomenon as "the beautiful flash of light attending the discharge of common electricity". The rapid transition from a non-conducting to a conductive state produces a brief emission of light and a sharp crack or snapping sound.
