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 there today 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?9 requirement permits the inclusion of lead since no replacement has yet been developed.
*
Bio-accumulative is defined as substances which accumulate within living organisms
**
Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
Energy Efficiency
The proper operation of the function requires a computer with VESA® DPMS power management capabilities. When used with a computer
equipped with VESA® DPMS, the monitor is
ENERGY STAR
®-compliant.
As an
