For workplaces, the Victorian Occupational Health and Safety Act and Regulations places an obligation on employers to provide and maintain for employees a safe working environment. To achieve a safe working environment, it is reasonable to establish controls for the prevention and mitigation of emergencies. Some sections of the regulations are very specific on these arrangements for certain types of work, but emergency planning should form part of any workplace.
Australian Standard AS3745 – Planning for Emergencies in Facilities, sets the standard for Emergency Planning. Its application goes beyond just workplaces, and includes any buildings and structures occupied by people, with the exception of Class 1a buildings (unless they are used as a workplace).
