Environmental Considerations

Appendix G

Chromate Plating

Some sheet steel and fasteners are plated with zinc and sealed with a chromate-
based dip. Shipping and handling of the chromate plating parts is typically not
restricted by environmental regulations, however, chromate is considered a
hazardous substance. Dispose of chromate plated parts according to local
regulations, not with general landfill refuse.

In Case Of Fire

This drive is highly protected against arcing faults and therefore it is very unlikely
the drive would be the cause of a fire. In addition, the materials in the drive are
self-extinguishing (i.e. they will not burn without a sustained external flame). If,
however, the drive is subjected to a sustained fire from some other source, some of
the polymer materials in the drive will produce toxic gases. As with any fire,
individuals involved in extinguishing the fire or anyone in close proximity should
wear a self-contained breathing apparatus to protect against any inhalation of
toxic gases.

Disposal

When disposing of the drive, it should be disassembled and separated into groups
of recyclable material as much as possible (i.e. steel, copper, plastic, wire, etc.).
These materials should then be sent to local recycling facilities. In addition, all
disposal precautions mentioned above must also be taken for those particular
materials.
