In many cases, the build-up of charge can be avoided by using special
materials, for example, garments and packaging can be made of antistatic
materials or materials that have high resistance, but yet are not insulators.
The best way to avoid damage by electrostatic discharge is a combination of
means and procedures that achieves the following goals:
| Avoid build-up of electrostatic charges.
|
Create a protected work environment that helps prevent electrostatic
discharges.
| Provide means for controlled discharge of any accumulated electrostatic
charges when entering the protected work environment.

:
An area in which ESDs can be handled with
minimum risk of damage as a result of electrostatic discharge
or fields, and in which the operator is not exposed to
additional risks, is called an ESD Protected Area (EPA).
Personnel Training
During production and assembly, equipment is handled in workspaces
especially prepared and certified to serve as a permanent EPA. However, in
many cases the environment in which the same equipment is installed or
maintained cannot be assumed to form an EPA with a permanently controlled
boundary. Therefore, all the work involving handling of unprotected ESDs
must be considered as
field work .
Field work in this context includes such activities as service and maintenance,
installation, site inspections, and commissioning of components and assemblies
classified as ESDs, together with associated packing and unpacking activities.
All the staff involved in field work must be trained to perform field work in the
same way as work performed in permanent EPAs with respect to the material
quality, personal responsibilities, training, labeling, and packing.
