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 colourgenerating 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 colourgenerating layers of display screens must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays, switches, and back-light systems, 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, except the back-light system.
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.
* Bio-accumulative is defined as substances which accumulate within living organisms.
** Lead, Cadmium and Mercury are heavy metals which are Bioaccumulative.
