What does labelling involve?
This product meets the requirements for the TCO'95 scheme, which provides for international
environmental labelling of monitors. The labelling scheme was developed as a joint effort by the
TCO (The Swedish Confederation of Professional Employees), Naturskyddsforeningen (The
Swedish Society for Nature Conservation) and NUTEK (The National Board for Industrial and
Technical Development in Sweden).
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 restrictions 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 conducts
its operations policy. The energy requirements include a demand that the monitor 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 monitor 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.

Brominated flame retardants are present in printed circuit boards, cables, wires, casings and
housings. In turn, they delay the spread of fire. Up to thirty percent of the plastic in a computer
casing can consist of flame retardant substances. These are related to another group of
environmental toxins, PCBs, which are suspected to give rise to similar harm, including
reproductive damage in fish eating birds and mammals, due to the bioaccumulative processes.
Flame retardants have been found in human blood and researchers fear that disturbances in
foetus development may occur.

TCO'95 demand requires that plastic components weighing more than 25 grams must not
contain organically bound chlorine and bromine.
Lead
Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the
nervous system and in higher doses, causes lead poisoning.
