In the United Kingdom Fire and Rescue Service a Fire Safety Officer (sometimes referred to as a Fire Officer) is a firefighter who has attained the rank of Sub-Officer (also known as a Watch Commander) or above and transferred from front line operational service into the Fire Safety Department of a Fire and Rescue Service. Fire Officers also have the power to place anyone committing an offense under caution Others transfer because it is an alternative way chance to climb promotional ladder or because it is an opportunity to experience another aspect of the fire service's role.
