Electrostatic Discharge
Electrostatic discharge = ESD
Indicates potential hazard for components at risk of ESD
Damage to Electronic Components
CAUTION: A grounding wrist‐strap should be worn to protect electronic
parts from electrostatic discharges when installing/removing them.
Electrostatic discharge (ESD) is a spark that is created by great differences
in potential in an electrically insulating material. The spark causes a very
short, high pulse of electrical current. Plastic tool grips can cause
electrostatic potential differences, which can damage sensitive components.
A charge from frictional electricity is usually the source of the difference in
potential. Frictional electricity is generated e.g. when walking on carpet, in
which case a person can receive a charge of approx. 30,000 V.
Personal Injury and Risk of Fire
While electrostatic discharges in parts of the body pose a risk only in that
they frighten a person, they can cause fires in high risk areas.
This also applies to handling flammable liquids and gases. Dust can also
ignite (e.g. mill dust explosion).
