Environmental Requirements
Brominated flame retardants
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 fisheating birds and
mammals, due to the bio-accumulative * 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. The relevant TCO'99 requirement states that batteries, the colour-generating layers of display
screens and the electrical or electronics components 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. Mercury is, for the time being, permitted in the
back light system of flat panel monitors as there today is no commercially available alternative. TCO aims on removing this exception when
a mercury free alternative is available.
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.
The TCO'95 requirement: neither CFCs nor HCFCs may be used during the manufacturing of the product or its packaging.
