2. Preventive measures against electrostatic discharges
This section deals briefly and in a non-exhaustive way with the means of prevention against ESD in the electronics industry. The means of prevention described in the standards are most often defined for a component sensitivity equal to or greater than 100 V according to the HBM model.
2.1 DES-protected areas
ESD control involves limiting the generation of static charges, and discharging these charges to earth, while limiting the discharge current to avoid damaging components.
Protected work areas (EPA: Electrostatic Protected Area) are clearly defined by ground markings and standardized signs, encouraging personnel to take precautions when handling ESD-sensitive components and equipment (ESDS: ElectroStatic Discharges Sensitive). In...

Regulations
Existing regulations cover the risks of explosion and/or fire that can be caused by electrostatic discharges in certain industrial environments. See European Directive 94/9/EC or ATEX 137 (for explosive atmospheres) for equipment and 1999/92/EC or ATEX 100A for worker safety.

Statistical and economic data
It is estimated that at least 60% of faults encountered in the electronics industry are due to electrical overload (EOS: Electrical Over Stress) or electrostatic discharge (ESD), and in this case 70% of faults are due to ungrounded personnel. Personnel are becoming increasingly aware of the ESD risk, but at the same time, the evolution of technology (continuous reduction in the size of electronic components)...
