English to Spanish Bus/Financial Printing & Publishing signage

from a signage policy.

Control signage should be appropriately posted at each ZXC facility and, as appropriate, office location, to provide for the safety and security of Company employees, contractors and visitors. While there may oftentimes be separate signage requirements associated with work-place safety and emergency procedures, this section provides for general recommendations regarding security applications. The guidance provided here is considered to be the minimum acceptable security requirements; additional signage may be applied as a matter of local custom or where required by law.
Minimum Requirements
Vehicle Gates
1. Wording: "All vehicles entering this facility are subject to inspection of contents upon entry and exit. Entry shall constitute acknowledgement of this right and consent to inspection."
2. Location: Affixed to the outside and inside of all gates that are manned or opened only when vehicles enter or leave and on the outside of the fence next to the gate if the gate is left open and unmanned.
3. Size: Not less than 30" X 36", letters not less than 1 ½ high.

Any ideas, folkZ?
Thank you.
