Ingress of water or liquid

Hazard Knowledge

The legislation refers to the risk of drowning from an increase in the level of a liquid. This could be a result of the hazard of ingress of water or liquids.

Liquids can flow into a confined space and lead to drowning; for example, the ingress of liquid when working in sewers or from other plant that has not been adequately isolated in an industrial situation.

The presence of a liquid can also lead to death, serious injury or an effect on health, depending on the nature of the liquid, such as its corrosiveness or toxicity. Drowning can occur in even a small depth of liquid.
