TCO Developm ent SE-114 94 Stoc kholm, Sweden Fax: +46 8 782 92 07 Email (Internet): [email protected] Current information regarding TCO'99 approved and labelled products may also be obt ained via the Internet, using the address: http://www.tco-info.com/ Environm ental requirements Flam e retardants Flame retardants are present in printed c ircuit boards, cables, wires, casings and hous ings. Their purpos e is to prevent, or at least to delay the s pread of fire. Up to 30% of the plastic in a computer casing can consist of flame retardant s ubstances. Most flame retardants contain bromine or c hloride, and thos e flame retardants are chemically related to another group of environmental tox ins, 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* proc esses. Flame retardants have been found in human blood and researchers fear that disturbances in foetus dev elopment may occ ur. The relevant TCO'99 demand requires that plastic components weighing more than 25 grams must not contain f lame retardants with organically bound bromine or chlorine. Flame retardant s are allowed in the printed circuit boards since no s ubstitutes are available. Ca dmi um** Cadmium is present in rechargeable batteries and in the colour -generating layers of certain computer displays. Cadmium damages the nerv ous 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 c ontain any cadmium. Mercury** Mercury is sometimes found in batteries, relays and switc hes. 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 elec tronics components associated with the labelled unit. There is however one exc eption. 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 ex ception when a Mercury free alternative is available. CFCs (freons) The relevant TCO'99 requirement s tates that neither CFCs nor HCFCs may be used during the manufacture and ass embly 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 inclus ion of lead sinc e no replacement has yet been developed. * Bio -accumulative is defined as substanc es which accumulate within liv ing organisms. ** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
