General Site Preparation Guidelines Environmental Elements • Ensure that all equipment and flooring are properly grounded and are at the same ground potential. • Use conductive tables and chairs. • Use a grounded wrist strap (or other grounding method) when handling circuit boards. • Store spare electronic modules in antistatic containers. • Maintain recommended humidity level and airflow rates in the computer room. Acoustics Computer equipment and air conditioning blowers cause computer rooms to be noisy. Ambient noise level in a computer room can be reduced as follows: • Cover the ceiling with a commercial grade of fire-resistant, acoustic rated, fiberglass ceiling tile. • Cover the walls with curtains or other sound deadening material. • Use foam rubber models as removable partitions for most effectiveness. 42 Appendix B

Cover the ceiling with a commercial grade of fire-resistant, acoustic rated, fiberglass ceiling tile.
•
Cover the walls with curtains or other sound deadening material.
•
Use foam rubber models as removable partitions for most effectiveness.
