Environmental Requirements
Brominated flame retardants are present in printed circuit boards, cables, wires, casings and housings. In turn, they delay
the spread of fire. Up to thirty percent of the plastic in a computer casing can consist of flame retardant substances. These
are related to another group of environmental toxins, PCBs, which are suspected to give rise to similar harm, including
reproductive damage in fish eating birds and mammals, due to the bioaccumulative processes. Flame retardants have
been found in human blood and researchers fear that disturbances in foetus development may occur. TCO'95 demand
requires that plastic components weighing more than 25 grams must not contain organically bound chlorine and bromine.
Lead
Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the nervous system and in
higher doses, causes lead poisoning. TCO'95 requirement Permits the inclusion of lead since no replacement has yet
been developed.
Cadmium
Cadmium is present in rechargeable batteries and in the colour generating layers of certain computer displays. Cadmium
damages the nervous system and is toxic in high doses. TCO'95 requirement states that batteries may not contain more
than 25 ppm (parts per million) of cadmium. The colour-generating layers of display screens must not contain any
cadmium.
Mercury
Mercury is sometimes found in batteries, relays and switches. Mercury damages the nervous system and is toxic in high
doses. TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million) of mercury. It also
demands that no mercury is present in any of the electrical or electronics components concerned with the display unit.
CFCs (freons)
CFCs (freons) are sometimes used for washing printed circuit boards and in the manufacturing of expanded foam for
packaging. CFCs break down ozone and thereby damage the ozone layer in the stratosphere, causing increased reception
on Earth of ultraviolet light with consequent increased risks of skin cancer (malignant melanoma).
.
The relevant TCO'95 requirement: Neither CFCs nor HCFCs may be used during the manufacturing of the
product or its packaging.
