Computer health and safety is necessary to keep the system in good condition. The system should be kept in the appropriate place where it could get fresh air and temperature. Excessive temperature can harmed the system so it should be kept in appropriate place. We should protect the system from the dust particles. Regular back up of crucial document and file is necessary in order to protect from the loss of data. updated anti-virus program should be installed to the system to protect from the access of malicious and spy ware programs(which has the destructive nature).so these types of precautions should be followed to keep the computer in the proper condition. Noise is an inevitable part of the office life, and most of us are able to filter out and ignore sounds, which mean little to us. Noise becomes a nuisance when it exceeds levels, which we can ignore, even when the content of the sound is irrelevant to what we are doing. Our ability to hear serves primarily as a means of communication between individuals, but it has a secondary role as an alarm mechanism. Unexpected, unfamiliar or loud noises trigger hand to the interpretation of sound and preparation of an appropriate response. if this happens regularly, it becomes more difficult to concentrate. Being in a constant state of mild alarm is also exhausting, making comparatively mild noise levels distracting during the office work.
