It is important that you carry out your fire risk assessment in a practical and systematic way. It must take the whole of the workplace into account, including outdoor locations and any rooms and areas which are rarely used.
If your workplace is small you may be able to assess the workplace as a whole. In larger buildings, you will often find it helpful to divide the workplace into rooms or a series of assessment areas using natural boundaries, e.g. process areas, offices, stores, workshops as well as corridors, stairways and external routes.
If your workplace is in a building shared with other employers, you and all the other occupiers and any other person who has control of any other part of the workplace will need to discuss your risk assessments. This will help to ensure that any areas of higher risk, and the need for any extra precautions, are identified.
