A fire and rescue service is calling for people to sign up as on-call firefighters.

Half of Hertfordshire County Council's Fire and Rescue Service's engines are crewed by part-time firefighters who are on call to respond to emergencies alongside their normal jobs.

The service is now looking to recruit more people who live four or five minutes from a fire station to train up, ensuring a full crew is on standby at all times.
