Environmental requirements
Flame retardants
Flame retardants are present
in printed
circuit
boards,
cables,
wwes, casings
and housings
Their
purpose
is to preverr~ or at least to delay the spread of tire. 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
ofenwronmental
toxins, PCBS. Both the flame
retardants
contain ing bromine
or chloride
and the PCBS are suspected
of giving
rise to severe
health
effects,
nrcludlng
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
foeicrs development may occur
The relevant
TC099
demand
requires
that plastic
components
weighing
more than 25 grams must not
contain
flame
retardants
with orgarrlcally
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
m high doses. The relevant
TC099
requirement
states that batter] es, the colour-generating
layers of dmplay
screens and the electrical
or
electronics
components
must not contain
any cadmium.
Mercurya"
Mercury
is sometimes
found
in batteries,
relays and switches.
It damages
the nervous
system and is
toxic in high doses
The relevant
TC099
requwement
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 Iabelled
unit
There
is however
one exception.
Mercury
is, for the hme being, permmed
in the
back I]ght system of flat panel monitors
as there today is no commercially
available
alternative
TCO
alms on remowng
this exception
when
a mercury
free alternative
IS avadable.
CFCS (freons)

TC099
requirement
states that neither

Lead
can be found
in picture

Lead

and m higher
doses, causes
lead poisoning.
The relevant
TCO '99 requirement
permits
the
irrclus]on
of lead stnce no replacement
has yet been developed.
