Environmental Requirements
* Bio-accumulative is defined as substances which accumulate within living organisms.
Mercury
Mercury is sometimes found in bat-
teries, relays and switches. Mercury
damages the nervous system and is
toxic in high doses.
batteries may not contain more than
25 ppm (Parts per million) of mer-
cury. It also demands that no mer-
cury is present in any of the electri-
cal or electronics components con-
cerned with the display unit.
Lead
Lead can be found in picture tubes, dis-
play screens, solders and capacitors. Lead
damages the nervous system and in hig-
her doses, causes lead poisoning.
clusion of lead since no replacement has
yet been developed.
Cadmium
Cadmium is present in rechargeable bat-
teries and in the colour generating lay-
ers of certain Computer displays. Cadmi-
um damages the nervous system and is
toxic in high doses.
teries may not contain more than 25 ppm
(Parts per million) of cadmium.The co-
lour-generating layers of display screens
must not contain any Cadmium.
CFCs (freons)
CFCs (freons) are sometimes used
for washing printed circuit boards
and in the manufacturing of expan-
ded foam for packaging. CFCs break
down ozone and thereby darnage the
ozone layer in the stratosphere, cau-
sing increased reception on Earth of
ultraviolet light with consequent in-
creased risks of skin cancer (malig-
nant melanoma).
ment: Neither CFCs nor HCFCs may
be used during the manufacturing of
the product or its packaging.
