The Act sets out the general obligations which businesses have towards workers and individuals from the general population, and representatives need to themselves and to each other.
These obligations are qualified in the Act by the guideline of 'so far as is sensibly practicable' as such, a business does not need to take measures to maintain a strategic distance from or lessen the danger on the off chance that they are in fact outlandish or if the time, inconvenience or cost of the measures would be terribly unbalanced to the danger.
What the law requires here is the thing that great administration and judgment skills would lead bosses to do in any case that is, to take a gander at what the dangers are and take sensible measures to handle them.
