Printed Circuit Boards
Printed circuit boards may contain lead in components and materials. Shipping
and handling of these boards are typically not restricted by environmental
regulations, however, lead is considered a hazardous substance. Circuit boards
must be disposed of according to local regulations and must not be disposed of
with general landfill refuse.
Chromate Plating
Sheet steel and fasteners may be plated with zinc and sealed with a chromate-
based dip (gold- or silver-colored finish). Shipping and handling of chromate
plated parts are typically not restricted by environmental regulations, however,
chromate is considered a hazardous substance. Chromate plated parts must be
disposed of according to local regulations and must not be disposed of with
general landfill refuse.
In Case Of Fire
This product is highly protected against arcing faults and therefore it is very
unlikely it would be the cause of a fire. In addition, the materials used are self-
extinguishing (i.e. they will not burn without a sustained external flame). If,
however, the product is subjected to a sustained fire from some other source,
some of the polymer materials 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 product, it should be disassembled and separated into
groups of recyclable material as much as possible (for example, 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.
