Determining the correct number of protective enclosures is essential for compliance and safety. How many fire extinguisher cabinets should be in a space depends on building size and local regulations. This guide explains calculation methods and placement requirements for portable firefighting equipment across European countries.
Understanding Fire Extinguisher Cabinet Requirements
Fire extinguisher cabinets serve dual purposes: they protect firefighting equipment from environmental damage and ensure visibility and accessibility during emergencies. The number of protective enclosures required in any given space isn't arbitrary—it's governed by a combination of building codes, occupancy types, and square footage.
Unlike exposed extinguishers, cabinets offer additional protection against tampering, weather conditions in semi-outdoor areas, and aesthetic integration within architectural designs. This is particularly important for interior architects who must balance safety compliance with visual harmony.
Why Cabinet Quantity Matters
Installing too few cabinets creates dangerous gaps in coverage distance regulations for suppression devices. Too many cabinets, while safe, represents unnecessary expenditure and potential visual clutter. The optimal number ensures:
- Compliance with national and local fire safety codes
- Maximum travel distance requirements are met
- Adequate protection for high-risk areas
- Cost-effective safety implementation
- Seamless integration with interior design

Key Factors Determining Cabinet Quantity
Several variables influence how many fire extinguisher cabinets should be in a space. Understanding these factors helps facility managers and architects make informed decisions.
Building Square Footage
Total floor area remains the primary determinant. Most European regulations use a ratio-based approach linking cabinet quantity to surface area. For example, the EN 3 standard (European standard for portable fire extinguishers) provides guidance on extinguisher distribution based on fire risk levels.
Occupancy Classification
Different building uses demand different approaches:
- Office spaces: Lower fire risk, standard coverage
- Retail environments: Higher foot traffic, increased requirements
- Industrial facilities: Elevated risk, specialized equipment needed
- Healthcare facilities: Critical safety needs, redundant coverage
- Hospitality venues: Public access areas require strategic placement
Fire Risk Assessment
A comprehensive fire risk assessment evaluates:
- Combustible materials present
- Ignition sources
- Evacuation routes
- Historical incident data
- Process-specific hazards
Higher risk ratings typically require reduced travel distances and therefore more cabinets per square meter.
Building Layout and Obstructions
Open-plan spaces require fewer cabinets than compartmentalized layouts. Corridors, stairwells, and physical barriers affect optimal placement requirements for portable firefighting equipment. Architects must account for:
- Wall configurations
- Column placement
- Accessibility compliance
- Visibility from multiple angles
- Obstruction-free access
European Regulatory Standards by Country
European countries follow harmonized standards while maintaining national specifications. Here's a breakdown of key regulations across major markets:
| Country | Primary Standard | Maximum Travel Distance | Typical Floor Area Coverage |
|---|---|---|---|
| Germany | ASR A2.2 | 20-30m depending on risk | 200-600 m² per extinguisher |
| United Kingdom | BS 5306-8 | 30m (Class A fires) | Based on fire rating units |
| Netherlands | NEN 2654 | 20-25m | 200-400 m² depending on use |
| Italy | D.M. 10/03/1998 | 30m | Varies by activity category |
| Spain | RD 513/2017 | 15-25m | Based on risk level |
Germany: ASR A2.2 Guidelines
German workplace regulations (ASR A2.2) specify that the number of fire extinguisher cabinets depends on the workplace risk category. Low-risk environments require one 6kg extinguisher per 200-300 m², while high-risk areas need coverage every 100-150 m².
United Kingdom: BS 5306-8 Standard
The British Standard uses a fire rating point system. Class A fire risks require a minimum 13A rating per 200 m² of floor space. Coverage distance regulations for suppression devices mandate that no person should travel more than 30 meters to reach an extinguisher for Class A fires.
Netherlands: NEN 2654 Approach
Dutch regulations emphasize risk-based assessment. The NEN 2654 standard requires cabinets positioned so maximum travel distance doesn't exceed 20 meters in most commercial buildings. Industrial settings may have stricter requirements.
Italy: Ministerial Decree Framework
Italian regulations categorize activities by fire risk (low, medium, high). Building size and cabinet quantity calculation follows prescribed ratios, with high-risk activities requiring one extinguisher per 100-150 m² and low-risk spaces per 200 m².
Spain: Real Decreto 513/2017
Spanish regulation distinguishes between surface risk and special risk zones. General spaces require coverage every 15 meters of travel distance, with specific requirements for high-occupancy areas and industrial processes.
Calculating the Number of Cabinets Needed
Determining how many fire extinguisher cabinets should be in a space requires systematic calculation. Follow this step-by-step methodology:
Step 1: Determine Total Floor Area
Measure the gross floor area in square meters. For multi-story buildings, calculate each floor separately as vertical travel distances apply different rules.
Step 2: Identify Occupancy Type and Risk Level
Classify your space according to local regulations:
- Low risk: offices, residential
- Medium risk: retail, light manufacturing
- High risk: chemical storage, woodworking
Step 3: Apply Coverage Ratio
Use the appropriate coverage ratio from your jurisdiction. For example, a 1,200 m² medium-risk German facility would require:
1,200 m² ÷ 200 m² per extinguisher = 6 extinguishers minimum
Step 4: Verify Travel Distance Compliance
Plot cabinet locations on floor plans ensuring no point exceeds maximum travel distance. This often requires more cabinets than the area ratio alone suggests.
Step 5: Add High-Risk Supplements
Supplement the base calculation with additional cabinets near:
- Electrical panels
- Kitchens or cooking areas
- Server rooms
- Chemical storage
- Workshop areas
Practical Calculation Example
Scenario: 800 m² office space in the Netherlands, low-risk classification
- Base calculation: 800 m² ÷ 300 m² = 2.67, round up to 3 cabinets
- Maximum travel distance: 20 meters
- Layout check: L-shaped office with 60m longest dimension
- Additional cabinet needed for distance compliance
- Final requirement: 4 fire extinguisher cabinets
Coverage Distance Regulations for Suppression Devices
Travel distance—the actual path a person must walk to reach an extinguisher—is often more restrictive than area-based calculations. Coverage distance regulations for suppression devices prioritize rapid emergency response.
Measuring Travel Distance Correctly
Travel distance isn't straight-line measurement. It accounts for:
- Hallways and corridors
- Doorways and access points
- Furniture and fixtures
- One-way circulation patterns
- Accessibility obstacles
Always measure along the actual walking path, not as-the-crow-flies.
Class-Specific Distance Requirements
Different fire classes may have different maximum distances:
- Class A (combustibles): Typically 30m maximum in UK, 20-30m in Germany
- Class B (flammable liquids): Often 10-15m in high-risk areas
- Class F (cooking oils): Usually 10m maximum from cooking equipment

Multi-Story Considerations
Vertical travel adds complexity. Placement requirements for portable firefighting equipment generally mandate cabinets on every floor, near stairwells and exits. Don't assume occupants will travel between floors to access firefighting equipment.
Special Considerations for Different Building Types
Different environments present unique challenges for determining how many fire extinguisher cabinets should be in a space.
Office Environments
Open-plan offices allow fewer cabinets due to unobstructed sightlines and travel paths. However, private offices, meeting rooms, and storage areas may create coverage gaps. Place cabinets:
- Near main entrances
- At corridor intersections
- Near server rooms and electrical closets
- In kitchenettes and break rooms
Retail Spaces
Public access buildings require highly visible cabinet placement. Customer circulation patterns differ from employee routes. Consider:
- Front-of-house versus back-of-house coverage
- Seasonal layout changes
- Display fixtures that obstruct access
- After-hours versus operating-hours access
Industrial Facilities
Manufacturing environments often have segregated risk zones. Building size and cabinet quantity calculation must account for process-specific hazards. Specialized extinguishers for metal fires, electrical equipment, or chemical processes may require dedicated cabinets.
Healthcare Facilities
Hospitals and care homes face unique challenges:
- Vulnerable occupants with limited mobility
- 24/7 operations
- Infection control protocols
- Medical gas and electrical equipment risks
Higher redundancy and reduced travel distances are standard.
Educational Institutions
Schools require cabinets that balance accessibility with tamper-resistance. Locations should be:
- Visible to staff
- Accessible during emergencies
- Strategically placed in high-traffic areas
- Supplemented in laboratories and workshops
Practical Examples and Case Studies
Real-world applications illustrate how regulations translate into actual installations.
Example 1: 600 m² UK Office
Parameters:
- Single-floor open-plan office
- Low fire risk
- Rectangular layout: 40m × 15m
Calculation:
- BS 5306-8: Minimum 13A rating per 200 m²
- 600 m² ÷ 200 m² = 3 extinguishers
- Maximum travel distance: 30m
- Longest dimension: 40m
Solution: 3 fire extinguisher cabinets positioned at each end and center of the long axis, ensuring no point exceeds 20m travel distance.
Example 2: 1,500 m² German Retail Store
Parameters:
- Ground floor retail with storage area
- Medium fire risk
- Complex layout with fitting rooms and stockroom
Calculation:
- ASR A2.2: 200 m² per extinguisher for medium risk
- 1,500 m² ÷ 200 m² = 7.5, round to 8
- Maximum travel distance: 25m
- Stockroom classified as higher risk
Solution: 8 base cabinets plus 2 additional in stockroom = 10 fire extinguisher cabinets total, including specialized Class F units near staff kitchen.
Example 3: Multi-Story Dutch Office Building
Parameters:
- 3 floors, 400 m² per floor (1,200 m² total)
- Low risk
- Central stairwell with corridors
Calculation:
- NEN 2654: 300 m² coverage per extinguisher
- Per floor: 400 m² ÷ 300 m² = 1.34, minimum 2 per floor
- 20m maximum travel distance
- Each floor: 50m × 8m dimension
Solution: 2 cabinets per floor near stairwell exits = 6 fire extinguisher cabinets total across three floors, meeting both area and distance requirements.
