Eye Strain - Eye strain is quite common among people using monitors over extended periods of time. It can result in irritated eyes and blurred vision.

Solutions - to reduce eye strain, users should look away from the monitor and focus on a distant object from time to time to relax their eye muscles.

A screen glare deflector can help some users.

Back problems - Sitting at the computer for long periods of time is never comfortable. Leaning back in the chair reduces the pressure on the spine but then the arms have to reach forward to the keyboard creating muscle tension which leads to aches and pains in the neck, shoulders, back and arms.

Solutions - while working at the keyboard, the correct seating position is sitting upright with the feet flat and the lower arms and thighs in a roughly horizontal position. Adjustable chairs that give the maximum support for the back are also best.

Safety Risks:Power supply:•Computers are generally connected to 240v mains electricity and

must be treated with care. The computer should be properly earthed and the plugs should have the correct fuses

•Trailing electrical leads should be avoided to reduce the risk of tripping or them being damaged.

•There should be enough power sockets to avoid power sockets being overloaded

•Mains plugs and leads must be checked for safety once a year

Fire risks:•In case of a fire, the fire extinguishers should be powder-based

or CO2 (carbon dioxide) devices. •Water-based fire extinguishers should not be used on electrical

appliances.
