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 fetus development
may occur.
The relevant TCO'95/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' 95/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'95/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 labeled unit.
CFCs (freons)
The relevant TCO'95/TCO'99 requirement states that neither CFCs nor HCFCs may be used during the
