Under the Fire Safety Order, every employer, property owner, manager or occupier must create a written emergency plan that includes fire emergency procedures. It should set out what employees must do if they find a fire, and how people will be alerted, for example by audible alarms. It should describe how the workplace is evacuated, including arrangements for people with disabilities, and state that nobody re-enters the building until the fire service or the person in charge confirms it is safe.
It must name the assembly point, explain how attendance is checked there, and give the location and use of fire-fighting equipment. It should identify employees with specific responsibilities, including you as a fire warden, and explain how to contact the fire and emergency services and who is responsible for doing so.
