Yes, but you have two alternatives:
1) Store ESD sensitive items on grounded ESD surfaces
2) Store ESD sensitive items in enclosed ESD packaging that has ESD shielding property.
Per ESD-ADV53.1 ESD Protective Workstations Electrical Requirements “Workstation elements shall be connected to, and maintain electrical continuity to, the common point ground as follows:
Worksurfaces - Resistance: Between 1 x 10^6 ohms and 1 x 10^9 ohms
Surfaces of shelves and drawers intended to be used for unprotected ESD sensitive devices - Resistance: Between 1 x 10^6 ohms and 1 x 10^9 ohms”.
So if the ESD sensitive items are not in closed shielding bags, etc., the drawer or particle board surfaces should have 10^6 - 10^8 ohm grounded matting.
If surfaces are not conductive/dissipative and grounded, it would be considered outside the ESD protected area. And per ANSI/ESD S541 section 6.2 Outside an EPA “Transportation of sensitive products outside of an EPA shall require packaging that provides:
1. Low charge generation.
2. Dissipative or conductive materials for intimate contact.
3. A structure that provides electrostatic discharge shielding."
See Statshield ESD Shielding Bags and In Plan Handlers.
Per ANSI/ESD S541 section 7.2.2 Resistance of Dissipative Materials “A static dissipative material shall have a surface resistance of greater than or equal to 1.0 x 10^4 Ohms but less than 1.0 x 10^11 Ohms. Packaging materials that are in intimate contact with devices should be dissipative.”
