A.
The trainee should wear an anti-static wrist strap.

B.
The trainee should change to shoes with rubber soles.

C.
Wash the hands with alcoholic soap to dissipate the static electricity.

D.
After opening the case the trainee should spray anti-static spray on the internal components.

E.
The trainee should keep the workstation on an anti-static mat the whole duration of the task.
