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.

Congratulations
!
You have just purchased a TCO'99 approved and labelled product! Your choice has provided you with a product developed for
professional use. Your purchase has also contributed to reducing the burden on the environment and also to the further development of
environmentally adapted electronics products.
This product meets the requirements for the TCO'99 scheme which provides for an international environmental and quality labelling
labelling of personal computers. The labelling scheme was developed as a joint effort by the TCO(The Swedish Confederation of
Professional Employees), Svenska Naturskyddsforeningen(The Swedish Society for Nature Conservation), Statens
Energimyndighet(The Swedish National Energy Administration) and SEMKO AB.
