If a company made safety of paramount importance, it would soon be out of business. The reason for this is that if something is 'paramount' it is the top priority. But what is the top priority for any company? You have to agree that it is to make profit. On the other hand, the safest factory is an empty one; as soon as you bring in a machine and a person, it becomes inherently unsafe and you have to manage the risk. A simple example of managing a risk would be a trailing cable in an office environment that is covered by a cable cover/protector to reduce the chance of somebody tripping over it. Although this does not guarantee that tripping will be prevented, it does reduce the risk to what is called an acceptable or tolerable level. What this means is that we have chosen this control as an alternative to burying the cable and putting a socket in the floor - which would be deemed to be too expensive when balanced against the risk or, in legal terminology, it would not be 'reasonably practicable'.However, it must be recognised that the best control, which is burying the cable and installing a socket in the floor, would be reasonably practicable to implement at the design stage, because putting a socket in the floor at the design and planning stage would be no more expensive than putting one in the wall.
