Drowning chain

The drowning chain is a series of conditions that on their own, or together can lead to a person being drowned. Each link in the chain can lead on to another link, or directly to a drowning or near drowning. The chain is used by lifeguards as a basis for targeting their activity at preventing, rather than reacting to, drowning or other incidents.

The conditions that allow drowning to occur can be summarised by the 'drowning chain', in which each link can lead directly to an incident, or can lead on to the next link, and is shown below.
