Machine covers and metal tables are electrical grounds.They increase the risk of damage,
because they make a discharge path from your body through the ESD-sensitive part.
(Large metal objects can be discharge paths without being grounded.)
Prevent ESD-sensitive parts from being accidentally touched by other personnel and do not put
unprotected ESD-sensitive parts on a table.
Be extra careful in working with ESD-sensitive parts when cold-weather and heating is used,
because low humidity increases static electricity.
