# Control

Any ongoing measure which mitigates a risk’s severity, or reduces the likelihood of a risk occurring (prevention) is a control.

Examples of controls could be that compartments are protected by fire doors fitted with smoke seals (to prevent spread of smoke through a building) or that regular EICRs are performed (to ensure wiring is in good condition so the risk of an electrical fire is low).

Controls may be predefined, or a custom one may be added if predefined ones are not suitable. If an author adds a control they would like to appear against a checklist item in future during an assessment they can link it during the assessment.
