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!

Small Business Computer Consulting Appropriately Setting Your Rates

In small business computer consulting, $100 an hour can be a reasonable and livable rate. Why can setting your rates at $100 an hour make all the difference in the world?

Take the $100 an hour and multiply it by 1,500 hours a year. This is reflecting a 75% utilization rate; or 75% of a typical forty hour work week as billable time. Now youre at $150,000 a year gross.

Salary and Affordability

As a small business computer consulting firm, you will want to take a third of the gross and plow it into sales and marketing. Therefore you can afford a $40,000 base salary for your sales account executive. So, of that one third of your gross small business computer consulting income, $40,000 can go to the base salary and $10,000 can go to related marketing expenses.

Additionally, one third will take care of taxes, insurance and overhead items for the most part, and you have a third of it or $50,000 left to pay a technical staff salary.

Surpassing $100 an Hour

You may be considering exceeding a rate of $100 an hour for your small business computer consulting firm. At that point, you can hit what we call the not-so-imaginary-hourly-billing-rate ceiling.

Needless to say, if your small business computer consulting clients are paying $110 to $125 an hour, it gets even easier to be able to afford really bright, motivated, highly qualified sales and technical staff.

Higher Rates Equal Bigger Businesses

However, if you want to charge above $100 an hour in your small business computer consulting firm, youll almost always need to move above and beyond sweet spot small business clients into really large small businesses, medium size businesses and enterprise-sized accounts that require a different business model and technical skill set.

Once you do that, youre going to be operating under a completely different type of business model. And you will need even more polished and seasoned salespeople to be able to handle those accounts.

The Pros And Cons Of The All-in-one Computer Versus Traditional Desktops

There are many choices in the computer market with different models and designs all created for different benefits and uses. Computer manufacturers design systems made for all possible uses with a variety of features to perform any type of computing task. There are also different models and designs available and a whole mobile sector that makes it easy to compute from anywhere without being tied to a plug.

As far as desktop systems go there are two main designs, the all-in-one and the traditional desktop computer system. Each has its own benefits and pros and cons. The choice sometimes comes down to how and for what the computer will be primarily used.

The all-in-one model is where the monitor and CPU are part of one unit so you do not have a CPU tower and a separate monitor that takes up more space as is the case with the traditional desktop system. The all-in-one eliminates the bulky and messy cables and connection wires that are part of the traditional set up.

There are some important differences between an all-in-one desktop computer and a traditional desktop computer. The traditional desktop is big and bulky. It can take up a lot of room, especially when you have a limited amount of space, with the CPU tower, plus the monitor as well as other peripherals, such as a printer or scanner.

The all-in-one also has no cables except for the power cord and peripheral cables and so it creates much less clutter under your desk. Overall the all-in-one desktop is able to provide you with much more space because of its compactness and size, which makes it much more space friendly. Another benefit of them is the fact that they come with notebook computer components, which require less power and generate less heat and so they save on power, which saves some money.

There are some cons with the all-in-one models. As opposed to the traditional desktop computer, which has plenty of room for expansion such as adding a hard drive or more memory, the compactness of the all-in-one leaves little room for it. So while the all-in-one is more efficient, it is less upgradeable. But unless you need a lot of features or you are a power user, the all-in-one because is a great choice for aesthetics, space and power saving benefits. However, for extreme gamers or power users the traditional system is a better choice.

How To Scrap A Computer

Getting cash for computer scrap is one of the easiest ways to make money. Whats the use of leaving your old desktop in the corner to collect dust, when you can scrap it and make some extra cash? Since the inception of computer scrap recycling programs, and programs that offer cash for other types of electronic scrap, thousands of eco-enthusiasts have been praising the cash for electronic scrap industry and recommending the services to friends.

But what many do not know is that by paying attention to the following steps, hints, and tricks, you can prepare your computer to get scrapped in a way that will guarantee more cash in your pocket. When scrapping computers, volume is a crucial and deciding factor. Before attempting to sell your computer scrap on E-bay and other vendor sites, having at least 5-10 pounds of computer scrap would be in your best interest. That way, these vendors will be more interested in your items and pay you a greater amount.

Before scrapping a computer, be sure to evaluate the technology and make sure its actually worthless. Usually, working parts within a computer will be worth more than what youll get when selling your computer scrap to a vendor. Everything inside a computer is worth a different amount, because they are each composed of different precious metals. The main components of a computer are the case, disk drives, hard drives, motherboards, CPUs, RAM, PCIs, and power supply. When scrapping a computer, it is important that you can recognize and remove these components without causing damage to the system.

Remember, quantity is what matters, so amass as many parts of different desktops and laptops as you can before separating the computer scrap into the following categories: 1) Gold Fingers, 2) PCI boards and motherboards, 3) CPUs, and 4) RAM. Each of these categories pays a bit differently, which is why it is important to understand the classification process and criteria qualifications of these categories. By visiting e-scrap websites, doing research, and educating yourself about the technology found within your computers, you will be well on your way to making lots of cash for your electronic scrap.

While hard drives, computer cases, and disk drives can easily be sold to scrap yards, the other components of a computer should strictly be sold online. Online vendors will usually pay more, but with this convenience and larger payout comes a larger risk. So do your research, read reviews, and protect yourself from greedy online vendors whose main priority is ripping you off.
