Environmental Requirements

Flame retardants

Flame retardants are present in printed circuit boards cables wires casings and housings Their purpose is to prevent or at least to delay the spread offire Up to 30% ofthe plastic in a computer casing can consist offlame retardant substances Most flame retardants contain bromine or chloride and those flame retardants are chemically related to another group of environmental toxins PCBs Both the flame retardants containing bromine or chloride and the PCBs are suspected ofgiving rise to severe health effects including reproductive damage in fish-eating birds and mammals due to the bio-accumulative* processes Flame retardants have been found in human blood and researchers fearthat disturbances in fetus development may occur.

The relevant TCO'99 demand requires that plastic components weighing more than 25 grams must not contain flame retardants with organically bound bromine or chlorine Flame retardants are allowed in the printed circuit boards since no substitutes are available.

Cadmium**

Cadmium is present in rechargeable batteries and in the color-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 color-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 It damages the nervous system and is toxic in high doses The relevant TCO'99 requirement states that batteries may not contain any mercury It also demands that mercury is not present in any ofthe electrical or electronics components associated with the labeled unit.

CFCs (fréons)

The relevant TCO'99 requirement states that neither CFCs nor HCFCs may be used during the manufacture and assembly ofthe product CFCs (fréons) are sometimes used forwashing printed circuit boards CFCs break down ozone and thereby damage the ozone layer in the stratosphere causing increased reception on earth of ultraviolet light with increased risks e.g skin cancer (malignant melanoma) as a consequence.
