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 of fire. Up to 30% of the plastic in a computer casing can consist of

flame 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 of giving 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 fear that disturbances in foetus 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 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. 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 of the electrical or electronics components associated with the

labelled unit. There is however one exception. Mercury is, for the time being, permitted in the back light

system of flat panel monitors as today there is no commercially available alternative. TCO aims on removing

this exception when a Mercury free alternative is available.

CFCs (freons)

The relevant TCO'99 requirement states that neither CFCs nor HCFCs may be used during the manufacture

and assembly of the product. CFCs (freons) are sometimes used for washing 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 e.g. increased risks of skin cancer (malignant melanoma) as a consequence.

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. The relevant TCO'99 requirement permits the inclusion

of lead since no replacement has yet been developed.
