6-Point checklist for creating
and maintaining an EPA
CONTROL PLAN Includes e.g. component/product sensitivity levels, ESD protection level, daily routines and
1
maintenance procedures.
2 FLOORING Grounded ESD floor or mat enables convenient usage of trolleys and chairs in EPA.
3 FURNITURE All furniture in EPA needs to be grounded.
4 PERSONNEL Wrist strap is the most efficient way to ground people working on EPA.
5 STORING, MOVING AND PACKING Store ESDS components in their original packages and minimise
the transportation and movements.
6 CLEANING AND TESTING Regular cleaning with ESD detergent in EPA maintains the ESD protection.
