Airborne Contaminants

Airborne particulates can damage tape libraries, drives, and tapes. The operating
environment for the tape library must meet to the following requirements:
ISO 14644-1 Class 8 Environment
■
Total mass of airborne particulates must be less than or equal to 200 micrograms
■
per cubic meter
Severity level G1 per ANSI/ISA 71.04-1985
■
Particles ten microns or smaller are particularly harmful to most data processing
hardware. Gasses that are particularly dangerous to electronic components include
chlorine compounds, ammonia and its derivatives, oxides of sulfur, and petrol
hydrocarbons. In the absence of appropriate hardware exposure limits, health
exposure limits must be used.
Humidification with chlorinated water is a common source of airborne chlorine.
Appropriately-designed carbon filters must be used to ensure safe levels of airborne
chlorine when chlorinated water is used for humidification.

Some basic precautions to follow:
Do not allow food or drink into the data center.
■
Do not store cardboard, wood, or packing materials in the data center clean area.
■
Identify a separate area for unpacking new equipment from crates and boxes.
■
Do not allow construction or drilling in the data center without first isolating
■
sensitive equipment. Dry wall and gypsum are especially damaging to equipment.

Seismic or Earthquake Ratings

The requirements for seismic compatibility vary dramatically throughout the world.
Therefore, Oracle does not offer a standard "seismic" feature for the SL3000 library. If
you have seismic concerns, Oracle recommends that you work with local experts who
are familiar with the local code and requirements. Professional Services can also help
coordinate this activity.
Caution: Bodily injury and equipment damage: You must consult a
qualified seismic engineer to verify seismic zone exposures and
adequate site preparation.
