What are brominated flame retardants and why are they needed in computers?


Brominated flame retardants (BFRs) are organobromide compounds that have an inhibitory effect on the ignition of combustible organic materials. It is needed in computers because computers are the most widely used electronic technology in a long period of time. Using this, computers will have a reduced flammability. 

Who is the Greenest Computer Company?      a.   Dell?     b.  Apple

Dell is much a greener computer company than Apple.

Find out all the chemicals used in the making of a computer:

Solvents
Xylene(xylol, dimethylbenzene) - High fire hazard
Chlorinated Hydrocarbons
Glycols
The chip manufacturing industry is extremely complicated. Here are two of the most common ways workers are being exposed to chemicals.Solvents are widely used in electronics for cleansing, stripping, degreasing, operations, encapsulation, and as solders. These are activities which are defining the work day for many workers in Silicon Valley. Solvents are also the cause of a large portion of workplace hazards and exposure problems in the industry. The following have been chosen because of their frequency in the industry.
Aromatic Hydrocarbons
  • Benzene (benzol) - High fire hazard
  • 1,1,1-trichloroethane (methyl chloroform)
  • tetrachloroethane(1,1,2,2-tetrachlorethane)
  • ethylene glycol (glycol, EG, glycol alcohol)
  • methyl collosolve
Gases
The industry uses many potentially dangerous gases. Gases are found in ion implanters, diffusion furnaces, expitaxial reactors, etc. Gases are also used in quality control to detect flaws in electronic components. According to an industry journalist, many semiconductor diffusion furnaces are "all too likely to explode." So the exposure can be over a long period of time, or from a short blast.

How can St Pats students do something to recognize Earth Day and increase Awareness of E waste?

St Pats should have a seminar, symposium, or camps in which they are educated on what is e waste and what should we do aboout it.They should impliment a program in the school to prevent rapid accumulation of e waste. The action should start first in school and they could also help different communities about this.
