Provides guidance for anyone involved with the management of health and safety at recreational dive sites and is aimed primarily at site owners and operators. It describes the main risks at managed dive sites and recommends a series of steps that can safeguard the health and safety of employees, divers and other visitors to the site.

The guidance applies to any expanse of water, such as a quarry or a lake, where access to divers is controlled as part of a business. The principles may also apply to dive centres and sites where access is controlled to sheltered inshore water, such as private beaches or harbours.
