Under the Workplace Health and Safety Act 1995, an employer has a legal obligation to ensure the health and safety of everyone in the workplace -workers, customers and visitors. 

It is an employer's responsibility to find out about the hazards in the workplace and assess their potential to cause harm. Some hazards pose a significant threat to health and safety; others are relatively low risk. 

Then, if necessary, an employer must take steps  to control the risk, either by eliminating it, or reducing it to an acceptable level.
