FIRE MARSHAL REQUIREMENTS CALCULATOR
How many fire marshals does my workplace need?
Use our free fire marshal requirements calculator to estimate the level of cover your workplace may need based on your premises, occupancy and evacuation arrangements.
Plan practical fire-marshal cover
Answer a few questions about your premises, occupancy and evacuation arrangements. We'll give you a practical starting recommendation and point out where your fire risk assessment needs to lead the decision.
This is not a statutory ratio calculator.Northern Ireland fire-safety law does not set one universal fire-marshal number. Your fire risk assessment remains the authoritative basis for the arrangements you put in place.
Complete this calculator for one premises at a time. If your organisation operates from multiple sites, assess each premises separately.
