Static Protection Measures
Follow these precautions to minimize possible ESD-induced failures in the computer room:
• Install conductive flooring (conductive adhesive must be used when laying tiles).
• Use conductive wax (if waxed floors are necessary).
• 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:
• Dropped ceiling—Cover with a commercial grade of fire-resistant, acoustic rated, fiberglass ceiling tile.
• Sound deadening—Cover the walls with curtains or other sound deadening material.
• Removable partitions—Use foam rubber models for most effectiveness.
