Low Level Pc Poisons – Computer Fumes Dust And Gases

Copyright 2006 Michael Madigan

Did you know computer equipment continually gives out small amounts of different gases and fine dusts? Some people are highly sensitive to these.

Plastic PC components are one source, as most plastics are unstable and break down naturally over time, especially when exposed to ultraviolet light and sunlight. (That’s the reason why they turn yellow and get brittle.)

Another source comes from vapour produced from traces of manufacturing materials slowly evaporating.

The gases and fumes given off are called ‘out-gassing’ and only occur in small amounts. But when the equipment is new, the out-gassing is greater and noticeable even to people who aren’t particularly sensitive.

This is similar to the smell that we get when we first get into a new car – out-gassing from the vinyl, plastic carpet and hard plastic interiors, as well as the wiring.

A new computer has a similar smell. So to some extent you can avoid outgassing, at least of ‘new’ volatile components, by buying a good quality ‘used’ PC.

Other office materials, particuliarly new furnishings, may also outgas – chipboard contains phenolic resins, which release trace amounts of formaldehyde; also carpeting (especially foam padding), paint and fabrics give off obnoxious chemicals when new.

People who have been sensitized (by previous exposure) may react badly to even very tiny amounts of these gases, by getting headaches, dizziness, and respiratory problems. The problems may persist even when the original cause is reduced, or disappears. In such a case it’s wise to seek qualified medical advice.

Casings may also be contaminated by fine brominated phenolic dust originally put on as a fire retardant, which can be blown out by fans, circulation or movement.

The best solutions are :-

– Initally, to run any new equipment in an empty well ventilated room to allow most of the outgassing to occur before use.

– Always work in a room with good ventilation and avoid continual high room temperaturesoutgassing will increase as the temperature rises.

Laser printers emit a lot of toner dust, which contains carbon and solvents, and quite a few people are sensitive to it. You can smell it when the printer is on, and especially on freshly printed-paper. You may notice wheeziness, coughing, and sneezing.

People working at copy centers and service bureaus often suffer from headaches, and toner dust is the main suspect. NCR paper (‘carbonless’ paper) can also cause wheeziness.

Good ventilation, drawing air away from the operator and filtering out particles, will help reduce these reactions, but effective ventilation in a commercial or home office is sometimes hard to achieve, especially in sealed buildings.

You can try going outdoors and breathing deeply for 10 minutes every hour or so. Open doors, maybe have a fan on., and avoid routine (multiple) photocopying every single document.

Think long term. Removing even mild poisons from your environment is yet another way to keep safe, stay fitter at the PC and enjoy a healthy computing career!

Cbse India Introduces A Common Syllabus For Maths & Science!

The Union Ministry of Human Resource and CBSE India are leaving no stone unturned to make lives easy for school students across the various boards in India! The latest stride towards this endeavor is the introduction of a common syllabus for Maths and Science for the students of classes XI and XII across all the educational boards. Therefore, from the academic year starting 2011-12, students from all the boards in the country can look forward to a uniform syllabus!

An initiative like this by CBSE India will ensure a level playing field for all the students while they prepare for their engineering and medical entrance examinations. Hence, while all you students studying in classes XI & XII, preparing for your national level engineering and medical entrance exams from the year 2012, need no longer worry about the extensive syllabi covered by your friend in CBSE or other national/ state board.

A common syllabus is just the first step by the Human Resource Ministry and CBSE India towards a flexible pattern of education that is comparable to the education systems existing in the West. CBSE India also has plans in the pipeline to conduct a common entrance exam for Medical and Engineering courses in India by 2013. If such a plan by CBSE India gains acceptance from all the academic corners in the country, life after class XII is only set to get easier for students.

However, implementation of a common syllabus by CBSE India has also garnered a lot of criticism by NCERT. NCERT is of the view that Council of School Board of Education (COBSE) has no right to push the common syllabus agenda. NCERT believes that the decision to undertake any curriculum revision exercise should rightfully rest with itself as NCERT has been instrumental in all such changes over the past years. It also believes that COBSE is just a coordinating body between the various school boards in the country.

Amidst all this controversy, major stakes are now on successful implementation of this common syllabus scheme for Maths and Science. Success of a common syllabus like this could also spread cheer in the lives of students studying in the Commerce and Humanities streams. Talks are around for a uniform syllabus for various subjects in these streams as well. What more could have students asked for to ensure a smooth and stress-free studying experience!

There are various websites that provide CBSE-aligned learning resources for students studying in classes V-XII. A common syllabus for Maths and Science will also ensure that more students can now seek help from such websites and reap benefits of quality and extensive learning resources.

All students studying under CBSE India can expect a lot of good news in the near future as well.

All the best for the future!

Avoiding Downtime Via Computer Support

techno15

One of the things that operations managers would loathe is downtime. A downtime in business can be defined as a situation wherein operations could not continue. One of the leading causes of business downtime is the failure of equipment, specifically computer equipment. For example, if your offices email servers would go down then interoffice communication would usually cease. Even simpler, printer malfunction could lead to downtime as you wait for the paper jams to clear up.

Thus, businesses are often in the lookout for methods to be able to curb the downtime. A way that they would be able to do that is by contacting a Computer support firm. Computer support firms can help you solve this issue through a variety of ways such as:

24/7 support:

More often than not, breakdowns happen in times when people are not actively monitoring the situation. This would occur late into the shift and would often cause troubles the next day. If you have contacted a computer support firm to provide you with round the clock service, then you would not have to wait until the next day to detect or even fix the problems.
They could easily monitor your systems even if your own staff is not actively checking or guarding them. This would lead to a quicker response time than having to do next day fixes, avoiding he lengthy down times that managers hate.

Expert assessment:

Another common cause for downtime is the assessment and investigation that occurs whenever an issue is found. Usually operation is stopped as the IT experts would have to do a thorough checking on how the problem came up.

By contacting a computer support firm, you would be able to bank on their expert knowledge of handling the various computer systems. This means that investigation and assessment time is narrowed down as they would already have prior experience in solving various computer issues.
The help of the computer support team streamlines the time needed to be able to provide a solution for your computer problems.

Quick access to parts:

Lastly, a computer support company would have a much wider network from which to access replacement parts and accessories for your busted equipment. Usually, in house purchasing would have to go to a single supplier and hope that they have the parts that are needed for the fixes.
A computer support partner would have more options as they would usually have more connections.
