Environmental Labelling of Personal Computers
Congratulations! You have just purchased a TCO’95 approved and labelled
product! Your choice has provided you with a product developed for
professional use. Your purchase has also contributed to reducing the burden
on the environment and to the further development of environmentallyadapted electronic products.
Why do we have environmentally labelled computers?
In many countries, environmental labelling has become an established
method for encouraging the adaptation of goods and services to the
environment. The main problem as far as computers and other electronic
equipment are concerned is that environmentally harmful substances are
used both in the products and during their manufacture. Since it has not been
possible so far for the majority of electronic equipment to be recycled in a
satisfactory way, most of these potentially damaging substances sooner or
later enter Nature.
There are also other characteristics of a computer, such as energy
consumption levels, that are important from both the working and natural
environment viewpoints. Since all types of conventional electricity
generation have a negative effect on the environment (acidic- and climaticinfluencing emissions, radioactive waste, etc.), it is vital to conserve energy.
Electronic equipment in offices consumes as enormous amount of energy,
since it is often routinely left running continuously.
What does labelling involve?
This product meets the requirements for the TCO’95 scheme, which provides
for international environmental labelling of personal computers. The
labelling scheme was developed as a joint effort by the TCO (The Swedish
Confederation of Professional Employees), Naturckyddsfˆreningen (The
Swedish Society for Nature Conservation), and NUTEK (The National
Board for Industrial and Technical Development in Sweden), and SEMKO
AB (an international certification agency).
iii
The requirements cover a wide range of issues: environment, ergonomics,
usability, emission of electrical and magnetic fields, energy consumption and
electrical and fire safety.
The environmental demands concern, among other things, restriction on the
presence and use of heavy metals, brominated and chlorinated flame
retardants, CFCs (freons), and chlorinated solvents. The product must be
prepared for recycling, and the manufacturer is obliged to have an
environmental plan, which must be adhered to in each country where the
company implements its operational policy.
The energy requirements include a demand that the computer and/or display,
after a certain period of inactivity, shall reduce its power consumption to a
lower level, in one or more stages. The length of time to reactivate the
computer shall be reasonable for the user.
Labelled products must meet strict environmental demands, for example, in
respect of the reduction of electric and magnetic fields, along with physical
and visual ergonomics and good usability.
The following is a brief summary of the environmental requirements met by
this product. The complete environmental criteria document may be ordered

iv
TCO’95 Environmental Requirements
Brominated flame retardants are present in printed circuit boards, cabling,
casings, and housings, and are added to delay the spread of fire. Up to 30%
of the plastic in a computer casing can consist of flame-retardant substances.
These are related to another group of environmental toxins, PCBs, and are
suspected of giving rise to similar harm, including reproductive damage in
fish-eating birds and mammals. Flame retardants have been found in human
blood, and researchers fear that they can disturb fetus development.
Bio-accumulative TCO’95 demands require that plastic components
weighing more than 25 grams must not contain flame retardants with
organically bound chlorine or bromine.
Lead can be found in picture tubes, display screens, solder, and capacitors.
Lead damages the nervous system and in higher doses causes lead poisoning.
The relevant bio-accumulative TCO’95 requirement permits the inclusion of
lead, as no replacement has yet been developed.
Cadmium is present in rechargeable batteries and in the color-generating
layers of certain computer displays. Cadmium damages the nervous system
and is toxic in high doses. The relevant bio-accumulative TCO’95
requirement states that batteries may not contain more than 25 ppm (parts
per million) of cadmium. The color-generating layers of display screens
must not contain any cadmium.
Mercury is sometimes found in batteries, relays and switches. Mercury
damages the nervous system and is toxic in high doses. The relevant bioaccumulative TCO’95 requirement states that batteries may not contain more
than 25 ppm of mercury and that no mercury is present in any of the
electrical or electronic components concerned with the display unit.
CFCs (freons) are sometimes used for washing printed circuit boards and in
the manufacture of expanded foam for packaging. CFCs break down ozone
and thereby damage the ozone layer in the atmosphere, causing increased
reception on Earth of ultra-violet light with consequent increased risks of
skin cancer (malignant melanoma). The relevant TCO’95 requirement:
Neither CFCs nor HCFCs may be used during the manufacture of the
product or its packaging.
1
Bio-accumulative means that the substance accumulates within living organisms.
v
Shipping Package
The packaging material can be recycled, or you can save it to return
the monitor to a service center for repair or disposal.
CFC Compounds in Distribution Packaging
Cushioning material used for shipping finished monitors are not
manufactured with nor do they contain any CFC compounds.
Design for Disassembly/Recycling
These monitors have been designed for easy end-of-life disassembly
and recycling. Fasteners are generally of the same type for efficient
disassembly. Components made of different materials can be easily
separated and plastics have been identified using international
symbols to aid in recycling.
Monitor Disposal
If you need to dispose of a monitor, ask a qualified service
representative for the proper procedure. Improper disposal
could result in personal injury from implosion.
