• Rate of change — a standard air conditioner both cools and removes
moisture from the air. The rate of change is how quickly the air in the
room is dried. The drier the air, the more static is generated. If you do
not use proper cooling equipment, air dryness can present problems.
• Separation — refers to the static discharge that can be generated when
two objects are separated. For example, printer paper is often stored in
cool dry conditions. If opened and used immediately, the act of
removing the paper from its box generates static. To allow the static to
discharge gradually over time, leave the box open in the computer
room for several hours before use.
Follow these precautions to minimize possible ESD-induced failures in
your computer room:
• Install conductive flooring (conductive adhesive must be used when
laying tiles).
• Use conductive wax if waxed floors are installed.
• Ensure that all equipment and flooring are properly grounded and are
at the same ground potential.
• Use conductive tables and chairs.
• Store spare electric parts in antistatic containers.
• Maintain recommended humidity level and airflow rates.
