Environmental Requirements
Flam e 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 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 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
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 ofcertain 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 CFOs nor HCFCs may be used during the
manufacture and assembly ofthe product. CFOs (fréons) are sometimes used forwashing printed
circuit boards. CFOs 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.
Lead**
Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the
