Control measure knowledge

Strategic actions

Fire and rescue services should:

Ensure that attending personnel are aware of the dangers presented by the inflow of liquids in confined space environments
Ensure that those supervising confined space operations are able to recognise and inform attending crews of this hazard

Tactical actions

Incident commanders should:

Identify the potential for liquids to enter confined spaces, including surface water
Isolate all sources of liquid ingress to confined spaces where possible
Implement suitable contingency arrangements where there is a risk of liquid ingress into a confined space

TRAINING SPECIFICATION

Learning outcome

Isolate or limit liquids

Understand:

The additional dangers in confined spaces where ingress of substances cannot be controlled
Contingency arrangements when flow of additional substances cannot be controlled

Refer to: Hazard – Flammable or explosive atmosphere; Control measure – Isolate or limit gases, liquids or other flowing materials
