There are many legal considerations that should be taken into account when building and using computer systems. If systems are being assembled by a company then there are many regulations and subsections of regulations that must be adhered to. When constructing a system it should be assembled in such a manner that the assembler is at minimum risk of injury and that there is minimum risk of injury to others.
Legislation is in place to ensure the safety of all concerned and is based on 'common sense' procedures - it is advisable to follow these procedures.
Once a system is assembled it must also meet legislative requirements. The 'new' computer system must be safe to use and the buyer or user must be at minimum risk of injury. For example, if the completed system was incorrectly assembled and the user received an electric shock then the system builder or manufacturer could be liable for damages.
Another common area of legislation concerns the day-to-day use of a computer system. Since many people use computer systems for prolonged periods of time they must also be at minimum risk of injury or disease. Legislation in this area covers items such as monitor position, lighting, noise, eye tests, etc. The aim is to reduce long-term damage due to bad posture, repetitive strain and other physical or mental damage.
