General Product Design


Any electronic equipment must be designed for safe operation. Most countries have some form of product liability legislation that puts the onus on the manufacturer to ensure that his product is safe. The responsibility devolves onto the product design engineer, to take reasonable care over the safety of the design. This includes ensuring that the equipment is safe when used properly, that adequate information is provided to enable its safe use, and that adequate research has been carried out to discover, eliminate, or minimize risks due to the equipment.
