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 chlorine, and those flame retardants are chemically related to PCBs. Both the flame
retardants containing bromine or chlorine and the PCBs are suspected of giving rise to health
effects, including reproductive damage in fish-eating birds and mammals, due to the bio-
accumulative* processes when not disposed of in accordance with strict standards for disposal.
