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

Bio-accumulative is defined as substances which accumulate within living

organisms
