Basics and Definitions
The fire triangle is a model illustrating the three essential components required for a fire to ignite and sustain combustion: Fuel, Heat, and Oxygen. If any one of these elements is removed, the fire cannot start or will be extinguished.

A fire warden (or fire marshal) is a trained employee appointed to manage fire safety, prevent risks, and lead safe evacuations in a workplace.
Read more: What is a Fire Warden and What Do They Do?
For buildings with shared spaces, the policy is either to evacuate or to stay put. Understanding which applies to you is vital for your safety.
Stay put policy: A fire safety approach where occupants remain inside their flat or unit because the building is designed to contain fire within compartments, keeping other areas safe.
Evacuation strategy: A plan that requires occupants to leave the building quickly and safely using designated escape routes when a fire alarm or danger is present.
Legal Responsibilities and Compliance
Yes. In the UK, fire safety training is mandatory for employees.
Employers are legally required under the Regulatory Reform (Fire Safety) Order 2005 to provide adequate fire safety training to all staff, including at induction and with regular updates.

Legal penalties for not complying with UK fire safety regulations can include fines, imprisonment, and enforcement action.
-
Minor offences can lead to fines (previously up to £5,000).
-
Serious breaches can result in unlimited fines and up to 2 years in prison.
-
Authorities may also issue enforcement or prohibition notices, which can restrict or close a building.
There is no fixed legal number of fire wardens in the UK — it depends on your fire risk assessment and the nature of your premises.
As a general guideline:
-
Low-risk workplaces: about 1 fire warden per 50 people
-
Medium risk: about 1 per 20 people
-
High risk: about 1 per 15 people
You should also ensure at least one warden per floor/area and enough to cover all shifts and absences.
No — in the UK, you do not need a Fire Certificate anymore.
Fire certificates were abolished under the Regulatory Reform (Fire Safety) Order 2005, and replaced with a system where the Responsible Person must carry out a fire risk assessment and manage fire safety on an ongoing basis.
Fire Risk Assessments
A Fire Risk Assessment (FRA) is basically a structured check of your building to identify fire hazards, evaluate the risk, and put measures in place to keep people safe.
In the UK, it’s a legal requirement under the Regulatory Reform (Fire Safety) Order 2005, enforced by authorities like London Fire Brigade.
What a Fire Risk Assessment involves
A proper FRA usually follows 5 key steps:
1️⃣ Identify fire hazards e.g.:
- Sources of ignition (electrics, heaters)
- Fuel (paper, furniture, flammable liquids)
- Oxygen sources
2️⃣ Identify people at risk e.g.:
- Staff, visitors, residents
- Anyone more vulnerable (elderly, disabled, lone workers)
3️⃣ Evaluate and reduce risk e.g.:
- Are there enough fire exits?
- Are alarms, extinguishers, and lighting adequate?
- What can be improved?
4️⃣ Record findings & act:
- Document what you found
- Fix issues (e.g. blocked exits, faulty alarms)
5️⃣ Review regularly:
- Update if things change (layout, staff, equipment)
- Revisit periodically to keep it current
Why it’s necessary
It’s the law
- If you’re a business owner, landlord, or responsible person, you must have one
- Failure can lead to fines or prosecution
🔥 Prevents fires (not just reacts to them)
- Identifies risks before something goes wrong
🧑🤝🧑 Protects lives
- Ensures people can escape quickly and safely
🏢 Protects property & business
- Reduces damage, downtime, and insurance issues
📋 Required for inspections
- Fire authorities like London Fire Brigade may ask to see it
🏠 Who needs one?
- Businesses (offices, shops, warehouses)
- Landlords (especially HMOs, flats with common areas)
- Public buildings
A typical single private home doesn’t legally require one.
Simple way to think about it
A Fire Risk Assessment is your plan to stop fires starting—and to make sure everyone gets out safely if one does.
In the UK, there’s no fixed “every X months” rule, but the Regulatory Reform (Fire Safety) Order 2005 says a Fire Risk Assessment (FRA) must be kept up to date. In practice, this means reviewing it whenever there’s a significant change—or at least periodically.
When to review or update your FRA
1️⃣ Periodic review
- Typical guidance: annually for most workplaces
- Some high-risk sites may require more frequent reviews (every 6 months or quarterly)
2️⃣ After significant changes
- Change of occupancy (more staff, visitors, residents)
- Building alterations or layout changes
- New equipment or processes (e.g., adding flammable materials, cooking areas)
- Change in fire safety systems (alarms, sprinklers, emergency lighting)
3️⃣ After a fire or near-miss
- Even a small incident should trigger a review
- Helps prevent repeat problems
4️⃣ After inspections or enforcement notices
- If the fire authority flags an issue, update the FRA to show corrective actions
Key point
The FRA is a living document that reflects the current risks and safety measures in your building.
Yes, in most cases you can carry out your own Fire Risk Assessment (FRA) in the UK—but it depends on the complexity and risk level of your building. The law doesn’t require you to hire a professional; what matters is that the assessment is “suitable and sufficient” under the Regulatory Reform (Fire Safety) Order 2005.
When you can do it yourself
- Small businesses or low-risk buildings (offices, shops, small flats)
- Simple layouts
- You have a good understanding of your building and its hazards
- You can identify:
- Fire hazards (ignition sources, flammable materials)
- People at risk
- Escape routes and fire safety measures
Many small businesses use official templates and checklists to ensure nothing is missed.
When you should consider a professional
- Large, complex buildings (multi-floor offices, warehouses, factories)
- High-risk environments (kitchens, chemical storage, industrial processes)
- Buildings with:
- Multiple tenants
- Complicated escape routes
- Fire suppression systems (sprinklers, gas suppression, alarms)
Professionals bring:
- Knowledge of UK standards (BS 5839, BS 5266)
- Experience identifying hidden hazards
- A report that may hold up better if inspected by fire authorities
Key point
Whether done yourself or by a professional, the FRA must be documented, acted upon, and reviewed regularly.
In the UK, a proper Fire Risk Assessment (FRA) follows five clear steps, as outlined in guidance from the Regulatory Reform (Fire Safety) Order 2005 and standards like BS 5839. Here’s the breakdown:
The 5 Steps of a Fire Risk Assessment
1️⃣ Identify Fire Hazards
- Look for sources of ignition (heaters, electrics, naked flames)
- Identify fuel sources (paper, textiles, flammable liquids)
- Spot oxygen sources that could intensify a fire
2️⃣ Identify People at Risk
- Consider everyone in the building: staff, visitors, residents
Pay special attention to:
- Elderly or disabled people
- Children or unaccompanied visitors
- People working alone
3️⃣ Evaluate, Remove, Reduce, and Protect from Risk
- Decide how likely a fire is to occur and its potential impact
- Take steps to reduce hazards, e.g.:
- Safe storage of flammable materials
- Regular maintenance of electrical equipment
- Ensure fire protection measures are in place: alarms, extinguishers, emergency lighting
4️⃣ Record, Plan, Inform, Instruct, and Train
- Document your findings in a fire log or report
- Develop an action plan for improvements
- Inform and train staff or occupants on:
- Fire procedures
- Location of exits and equipment
- Personal Emergency Evacuation Plans (PEEPs) if needed
5️⃣ Review the Assessment
- Update the FRA whenever there are changes:
- New equipment, processes, or layout
- Changes in occupancy or staff
- Conduct regular reviews (typically annually)
Rule of thumb:
Think of it as: “Spot hazards → see who’s at risk → reduce risk → record & train → keep it up to date.”
Equipment and Maintenance
In the UK, fire extinguishers are colour-coded and designed for specific types of fires. Using the wrong one can actually make things worse, so it’s worth knowing the basics
Types of Fire Extinguishers
🟥 Water (Red label)
- For: Class A fires
- Good for: Wood, paper, fabrics
- Avoid: Electrical, flammable liquids, grease fires
- Common in offices, schools
🟨 Foam (Cream label)
- For: Class A & B
- Good for: Solids + flammable liquids (like petrol)
- Avoid: Electrical (unless specifically rated)
- Often used in garages, warehouses
⬛ CO₂ (Black label)
- For: Electrical fires & Class B
- Good for: Computers, servers, electrical equipment
- Avoid: Confined spaces (less effective on solids)
- Leaves no residue (big advantage)
🟦 Dry Powder (Blue label)
- For: Class A, B, C + Electrical
- Good for: Multi-risk environments
- Avoid: Indoor/confined spaces (creates dust cloud, breathing hazard)
- Common in industrial settings
🟩 Wet Chemical (Yellow label)
- For: Class F + some Class A
- Good for: Cooking oils/fats (chip pans, deep fryers)
- Avoid: Most other fire types unless specified
- Essential in commercial kitchens
⚪ Specialist (less common)
- Dry Powder for Class D – specifically for metal fires
- Water Mist – safe for multiple classes including electrical (modern option)
In the UK, testing fire alarms and emergency lighting isn’t just “best practice”—it’s expected under fire safety law and guidance like those from British Standards Institution (e.g. BS 5839 and BS 5266). Here’s the practical schedule most workplaces follow:
🔔 Fire Alarm Testing
Weekly (user test)
- Test at least one call point (manual alarm) each week
- Rotate through different call points over time
- Check the alarm sounds clearly throughout the building
🛠️ Every 6 months (engineer service)
- A competent technician inspects and services the system
🔍 Daily (quick check)
- Just a visual check: panel shows no faults, power is on
💡 Emergency Lighting Testing
Monthly (function test)
- Simulate a power failure
- Check lights come on and stay lit briefly
- This is usually a short test (a few minutes)
🔋 Annually (full duration test)
- Lights must stay on for their rated duration (typically 3 hours)
- Confirms batteries will last in a real emergency
📋 Record Keeping (important)
- Keep a fire safety logbook
- Record every test, fault, and repair
- This may be checked by authorities like London Fire Brigade
A couple of real-world tips
- Do weekly alarm tests at the same time each week so people recognise it as a test
- Warn staff beforehand to avoid panic
- Fix faults immediately—don’t let them stack up
Most fire doors should be kept closed—but not all the time, and not always manually. It depends on how they’re set up.
🚪 Why fire doors matter
- Fire doors are designed to hold back fire and smoke, protecting escape routes so people can get out safely. Guidance comes from standards like those by British Standards Institution.
🔒 When fire doors MUST be kept shut
If it’s a standard fire door with a self-closing device, it should:
- Not be wedged open
- Close fully after use
These are common in:
- Stairwells
- Corridors
- Between high-risk rooms (like kitchens or plant rooms)
Wedging them open is a big no—this is something authorities like London Fire Brigade regularly flag.
When they can be open (legally)
Fire doors can be held open only if they have an approved system, such as:
- Electromagnetic hold-open devices linked to the fire alarm
- Acoustic retainers that release when the alarm sounds
In these cases, the door stays open normally but automatically closes if there’s a fire alarm.
🚫 What’s NOT allowed
- Door wedges, bins, or hooks to keep doors open
- Broken or missing self-closers
- Doors that don’t shut properly
🏠 At home vs workplace
- Homes: You don’t have to keep all internal doors shut, but it’s often safer at night
- Workplaces / flats / HMOs: Much stricter—fire doors are part of legal fire safety measures
Simple rule of thumb
- If it’s a fire door and it doesn’t have an automatic release system, it should be kept closed.
Read our Guide to Choosing the Right Fire Extinguisher.
There is no single fixed number in the UK—it’s based on a fire risk assessment, not a blanket rule. But there are clear principles you’re expected to follow under the Regulatory Reform (Fire Safety) Order 2005, enforced by bodies like London Fire Brigade.
The core rule
Your building must have enough fire exits for everyone to escape quickly and safely.
General guidelines (used in practice)
Small, simple buildings
1 exit may be enough if:
- Occupancy is low (roughly under 60 people as a rule of thumb)
- Travel distance to the exit is short
- Fire risk is low
Most workplaces / larger buildings
At least 2 exits are usually required
They should be:
- Independent (not both blocked by the same fire)
- Well-separated (different directions if possible)
Large / complex / high-risk buildings
May need 3 or more exits
Especially if:
- High occupancy (e.g. offices, retail, venues)
- Multiple floors
- Higher fire risk (kitchens, industrial use)
Other key factors (often more important than the number)
Fire safety isn’t just counting doors—it’s about:
- Travel distance – how far people must go to reach an exit
- Escape routes – must be clear, protected (often with fire doors)
- Width of exits – enough capacity for the number of people
- Accessibility – suitable for everyone, including disabled occupants
Guidance typically follows standards from British Standards Institution and government fire safety guides.
Situations where 1 exit is NOT acceptable
- Upper floors with no alternative escape
- High occupancy spaces
- Higher-risk environments (flammable materials, kitchens, etc.)
Simple way to think about it
You need more than one exit whenever a single fire could block the only way out.
What you should do
Carry out (or get help with) a fire risk assessment
This will determine the exact number and layout required for your building
Procedures and Drills
How often to do fire drills
1️⃣ Workplaces / Offices / Public Buildings
- Minimum: once a year
- Best practice: twice a year
Higher-risk environments (schools, hospitals, care homes, factories) may do drills quarterly or even monthly
2️⃣ HMOs / Flats / Residential Buildings with Multiple Occupants
- At least annually
- Must ensure everyone knows escape routes and assembly points
3️⃣ New Staff or Residents
- When someone new starts, give a mini induction drill or briefing
Key elements of a proper drill
- Sound the alarm and have everyone evacuate
- Use all escape routes to check they’re clear
- Time the evacuation to see if it meets safety targets
- Check attendance at assembly points
- Review any issues (blocked exits, slow response) and record them
⚠️ Important
- Drills should be planned and recorded in the fire logbook
- People should take them seriously, but it’s fine to warn staff/residents beforehand if necessary to prevent panic
Rule of thumb:
- At least once a year, but more often if risk or occupancy is high.

- A Personal Emergency Evacuation Plan (PEEP) is a tailored plan for individuals who may need extra help to evacuate safely during a fire or other emergency. In the UK, it’s a legal requirement under the Regulatory Reform (Fire Safety) Order 2005 for anyone with mobility issues, sensory impairments, or other vulnerabilities.Here’s what a PEEP should include:Key Elements of a PEEP1️⃣ Personal details
- Name, department/flat/room number
- Contact information (emergency contact if appropriate)
- Any relevant medical conditions
2️⃣ Nature of the assistance required
- Mobility support: wheelchair, walking aid, assistance from staff
- Sensory support: hearing, visual, or communication needs
- Cognitive support: instructions, guidance, or supervision during evacuation
3️⃣ Evacuation route
- Primary and secondary escape routes
- Accessible paths and stairs/lifts (if applicable)
- Points where assistance is needed (e.g., “needs support at stairwell”)
4️⃣ Equipment or aids required
- Evacuation chairs, lifts, ramps, or other devices
- Communication devices (alarms, paging systems, or mobile alerts)
5️⃣ Responsibilities
- Who will assist the person
- How they will be alerted in an emergency
- Any handover or check-in procedures at assembly points
6️⃣ Emergency assembly point and procedure
- Where the person will meet the assisting staff
- How they will be accounted for and kept safe
7️⃣ Training and testing
- Record any training given to the person and staff
- Include instructions for fire drills involving the PEEP
8️⃣ Review schedule
- Regular updates (usually annually or after any change in mobility, layout, or staff)
Practical tips
- Keep it simple and clear; it’s for quick action in an emergency
- Make sure all assisting staff know it
- Integrate it into your general fire safety plan
Rule of thumb:
- A PEEP is a step-by-step escape plan tailored to the individual, not just a note saying “needs help.”
You can find out more about PEEPs here.
In the UK, fire safety signage is a legal requirement under The Health and Safety (Safety Signs and Signals) Regulations 1996 and guidance from the Regulatory Reform (Fire Safety) Order 2005. The signage ensures people can find exits, fire equipment, and understand hazards quickly, especially in an emergency.
Here’s what you need to know:
Types of Fire Safety Signs
1️⃣ Fire Exit / Escape Route Signs
- Show the direction of escape
- Usually green with a white pictogram
- Must be clearly visible from all areas
Examples:
- “Fire exit →”
- “Emergency escape route”
2️⃣ Fire Equipment Signs
- Identify location of fire extinguishers, hose reels, alarms
- Red background with white pictogram
Examples:
- Fire extinguisher
- Fire alarm call point
3️⃣ Prohibition Signs
- Warn of actions that must not be taken, e.g., “No smoking near flammable materials”
- Red circle with a diagonal line
4️⃣ Mandatory Signs
- Actions that must be taken, e.g., “Keep fire door closed”
- Blue circle with white pictogram
5️⃣ Warning Signs
- Alert to hazards that could lead to fire or injury
- Yellow triangle with black symbol
Key Requirements
Visibility
- Signs must be clearly visible at all times
- Not blocked by furniture, equipment, or decorations
Consistency
- Use standard pictograms (BS EN ISO 7010)
- Match colour coding with the type of sign
Lighting
- Signs on escape routes must be illuminated or photoluminescent
- Ensure emergency lighting works if mains power fails
Positioning
- At decision points (e.g., junctions, stairways)
- At every fire exit and equipment location
Maintenance
- Keep signs clean, intact, and legible
- Replace damaged or faded signs immediately
Practical Tips
- For multi-floor buildings, repeat signs at each floor
- Fire doors should always have “Fire Door – Keep Shut” signs
- Combine exit signs with directional arrows to reduce confusion
Rule of thumb:
If someone unfamiliar with your building can’t find the fire exit in under 30 seconds, you probably need better signage.
If a fire alarm goes off but you don’t see any fire, you still need to treat it seriously—false alarms can happen, but assuming it’s safe can be very dangerous. Here’s what you should do in the UK:
Immediate Action
- Don’t ignore the alarm
- Always assume it could be real, even if there’s no smoke or flames.
- Follow your evacuation plan
- Leave the building immediately using the nearest safe fire exit.
- Do not use lifts.
- If there’s a PEEP (Personal Emergency Evacuation Plan), ensure anyone who needs assistance is supported.
- Go to the designated assembly point
- Wait there for further instructions.
- Do not re-enter the building until fire authorities or building staff say it’s safe.
While Evacuating
- Check doors for heat before opening (back of hand, quickly).
- Stay low if there’s smoke.
- Help others if needed, but don’t put yourself at risk.
After Evacuation
- Report your observations
- Tell your fire warden or responsible person if you saw/heard anything unusual.
- They will confirm whether it’s a false alarm.
- Wait for instructions
- Only return when cleared by fire wardens or the fire brigade.
- Do not try to investigate the cause yourself unless trained.
Dealing with Frequent False Alarms
Report repeated false alarms to building management or fire safety officer.
- Common causes include:
- Cooking smoke
- Steam from showers or kettles
- Dust, aerosols, or faulty detectors
Rule of thumb:
Treat every alarm as real until you’re told otherwise. It’s much safer than assuming it’s a false alarm.
