Have your plan ready before a fire breaks out.

Which extinguisher hangs where, how many metres is it from the farthest corner to an exit, and when is a fire escape stair needed? This page explains the basic rules of fire safety for Türkiye, the European Union, the United Kingdom and the USA, with sources. Nodaform's Safety step applies the same rules to your plan: you place an extinguisher, corners it can't reach turn red, the route to the exit and its distance are drawn, and the evacuation plan sheet is ready.

The wrong extinguisher makes a fire bigger

Every fire falls into a class based on what is burning, and each extinguisher puts out only certain classes. Spraying water on hot oil makes the flames explode; spraying water on a distribution board can cause an electric shock. The letters on the extinguisher tell you which classes it is suitable for.

A

Solids

Wood, paper, fabric, plastic. Burns and leaves embers.

B

Flammable liquids

Petrol, thinner, paint, alcohol.

C

Flammable gases

Natural gas, LPG, propane. Shut off the gas first.

D

Metals

Magnesium, aluminium powder, sodium. Workshops and laboratories.

F

Cooking oil

Fryer and pan oil. In the USA this class is called K.

⚡

Electrical

In Europe it's not a separate class; it's marked separately on the extinguisher. In the USA, class C means energised electrical equipment.

By space

Which room, which extinguisher

An extinguisher hangs not next to where a fire might start but on the route to it, in the direction of the exit: if you can't put the fire out, your back should be towards the door. Never behind a door, in a locked cupboard or next to a heater.

01 · Home

Kitchen and hallway

A small ABC powder extinguisher in the hallway, near the kitchen but not next to the hob; a fire blanket next to the hob. Never pour water on a pan fire: cover it with a lid or a blanket and turn off the hob.

02 · Electrical

Distribution board and server room

CO₂ extinguisher: leaves no residue and doesn't damage equipment. If possible, switch off the breakers first. Large server rooms get a fixed gas suppression system.

03 · Café and restaurant

Fryer and extractor hood

A class F (class K in the USA) wet chemical extinguisher next to the fryer. In large kitchens, an automatic suppression system in the hood and ductwork; which kitchens require one varies by country, so see the region tabs.

04 · Garage and car park

Vehicles and fuel

ABC powder extinguisher; in enclosed car parks and storerooms, also a large wheeled extinguisher. Where there are batteries and charging points, the electrical risk is also taken into account.

05 · Office and shop

On the escape route

An ABC powder or foam extinguisher near the exit, where everyone can see it; CO₂ next to the distribution board. Area and hazard determine the number; the limit on how far anyone may have to walk to an extinguisher varies by region.

06 · Workshop and storage

By hazard

Foam or powder if there are flammable liquids, class D metal powder if metal is worked. In high-hazard areas, more extinguishers are needed and travel distances are shorter.

Escape routes and fire escape stairs

How many metres from the farthest corner to an exit?

In a fire, it's smoke that kills people; that's why escape routes must be short, clear and protected. The rules ask the same questions in every country: how far do you walk from the farthest point to an exit or a protected stair, can you escape in two directions, are the doors and corridors wide enough for the number of people, and does the door open in the direction of escape?

  • One way, two ways. On a route with escape in one direction only, the permitted distance is much shorter; dead-end corridors are limited separately.
  • Sprinklers extend the distance. In buildings with automatic suppression, the permitted travel distance is usually longer.
  • In crowded spaces, doors open outward. Above a certain number of people (50–60 in most countries), the door must open in the direction of escape and must not be kept locked.
  • Fire escape stairs. A protected stair is an escape enclosure separated from smoke by its walls and doors. As a building gets taller, a second stair, pressurisation and a fire safety lobby are required; an external stair only counts if it meets the conditions.
  • The stair enclosure stays clear. No boiler, meter, air conditioner outdoor unit or belongings in an escape stair.

Fire escape stairs

Fire escape stairs: when and how?

A fire escape stair doesn't have to be a separate external stair; it's often a protected stair inside the building, separated from smoke by its walls and doors. The building's height determines when one is needed. The figures below are from Türkiye's fire regulation; other regions are at the bottom.

Apartment building section · fire escape stairsExample
21.50 m30.50 mpressurisation fanprotected stair enclosuresmoke-tight door,self-closingfire safety lobbyexternal escapestairwithin 3 munprotectedno openings±0.00+33.00

The elements are shown together; the table alongside tells you which ones each building needs.

When
In residential buildings up to a building height of 21.50 m, a normal stair is enough. Between 21.50 and 30.50 m, at least two stairs, one of them protected. Between 30.50 and 51.50 m, two protected stairs, one with a fire safety lobby or pressurisation. Above 51.50 m, both with a lobby and pressurisation. art. 48
Door
Stair and lobby doors are self-closing and smoke-tight; they resist fire for at least 60 min if they serve fewer than 4 floors, and at least 90 min if they serve a basement or more than 4 floors. The stair enclosure wall at least 120 min. art. 38, 47
Dimension
Riser height at most 17.5 cm, tread depth at least 25 cm. In high-rise buildings, stairs are at least 120 cm wide; stairs wider than 200 cm are divided by a handrail. art. 33, 41
Fire safety lobby
An intermediate space of 3–6 m² between the stair and the floor, with 120-minute walls and a 90-minute door, so that smoke doesn't get into the stair. art. 34
External stair
Can be used instead of an internal stair; there must be no less-protected doors or windows within 3 m of it. If the building height exceeds 21.50 m, an open external stair does not count as an escape stair. art. 42
Prohibited
No boiler, meter, air conditioner outdoor unit or belongings in the stair enclosure. A spiral stair counts as an escape stair only for up to 25 people and up to a height of 9.50 m. art. 41, 43

Other regions: in the United Kingdom (England), more than one common stair is recommended in new apartment buildings whose top floor is at 18 m or higher (since 30 September 2026, with transitional provisions; it does not apply to existing buildings). In the USA, escape stair enclosures connecting 4 or more storeys have a 2-hour fire-resistance rating, those connecting fewer have 1 hour (IBC 1023.2). In Germany, the walking distance from any point to a required stair enclosure or to the outside is at most 35 m. Source: Regulation on Fire Protection of Buildings · last checked 18 October 2026.

Extinguishing, detection and lighting

Where extinguishers aren't enough, systems take over

A portable extinguisher is for the first few minutes. Large, tall or crowded buildings need systems that detect a fire, raise the alarm and put it out automatically. The region tabs tell you which is mandatory in which building.

Sprinkler

Automatic sprinklers

The heads on the ceiling open one by one with heat and release water only over the fire. They may be mandatory in high-rise buildings, large car parks and shops; in some countries in new homes too.

Hose reels and hydrants

Fire hose reel cabinets, hydrants

Hose reel cabinets are inside the building; hydrants are outside, for the fire service. Cabinets are on escape routes, with a limited distance between them.

Kitchen

Kitchen hood suppression

A wet chemical system installed in the hood and ductwork above cookers and fryers; it also shuts off the gas.

Gas

Gas suppression

In server, archive and electrical rooms where water would cause damage, the room is flooded with gas. No one must remain inside.

Detection

Smoke, heat and CO detectors

Smoke detectors in bedrooms and hallways, heat detectors in kitchens; a carbon monoxide detector in homes with gas- or fuel-burning appliances. Mandatory in homes in some countries.

Alarm and guidance

Call points, emergency lighting, signs

Manual call points, sirens and strobes warn everyone; emergency lighting shows the way when the power goes out. Escape signs are white on green, firefighting equipment signs are white on red.

Rules by region

The figures differ from country to country

Fire rules are national; the same question gets a different number in each country. Below, we've summarised the main rules for four regions from the official texts, with article references. Depending on the building type, there may be further requirements; check the current text and your local fire service before applying them.

Main sources: the Regulation on Fire Protection of Buildings (2007; last amended 1 July 2025) and, for workplaces, the Regulation on Emergencies in Workplaces (2013).

Portable extinguishers
One 6 kg dry chemical powder (or equivalent gas) extinguisher for every 500 m² at low hazard and for every 250 m² at medium and high hazard. At most 25 m from any point to an extinguisher. 4–12 kg extinguishers are hung at a height not exceeding about 90 cm above the floor. Car parks, storerooms and plant rooms also get a wheeled extinguisher. art. 99
Maintenance
A general on-site inspection once a year; at the end of the fourth year, the extinguishing agent is renewed and a pressure test is carried out (TS ISO 11602-2) by an authorised company. art. 99/7
Travel distance
Without / with sprinklers, one way · two ways: apartment buildings 15 / 30 · 30 / 75 m; offices 15 / 30 · 45 / 75 m; shops, stores 15 / 25 · 45 / 60 m; hotels 15 / 20 · 30 / 45 m. Dead-end corridors 15 m (20 m with sprinklers). Within a flat, at most 20 m from any point to the flat entrance door (30 m with sprinklers); not required in residential buildings with no more than 4 storeys including the basement, or in detached houses. art. 32, 48, Annex 5/B
Doors, corridors, exits
Clear door width at least 80 cm, height 200 cm, no threshold. In spaces for more than 50 people, doors open in the direction of escape and are not kept locked; every space for more than 50 people has at least 2 exits. Corridors serving spaces at least 110 cm wide. art. 33, 39, 47
Fire escape stairs
In residential buildings up to a building height of 21.50 m, a normal stair is enough; between 21.50 and 30.50 m, at least two stairs, one of them protected; in taller buildings, two protected stairs and a fire safety lobby or pressurisation. Open external escape stairs cannot be used once the building height exceeds 21.50 m. No boiler, meter or air conditioner outdoor unit in the stair enclosure. art. 41, 42, 48
Sprinkler
Non-residential buildings over 30.50 m in height, residential buildings over 51.50 m, enclosed car parks larger than 600 m², multi-storey shops and shopping centres over 2000 m² and some accommodation buildings. art. 96
Detectors at home
In residential buildings, automatic detection is mandatory only where the building height exceeds 51.50 m. There is no national requirement for smoke and carbon monoxide detectors in homes; fitting them is still recommended. art. 75, Annex 7
Emergency lighting, signs
At least 60 minutes on all escape routes (120 minutes in buildings for more than 200 people), at least 1 lux along the centre line of the route. In buildings with more than one exit, a white "ÇIKIŞ" (EXIT) sign on a green background, 200–240 cm above the floor. art. 72, 73
Evacuation plan
All workplaces prepare an emergency plan; an evacuation plan showing escape routes and assembly points is posted at eye level at entrances and on each floor. Drills at least once a year. Workplace Emergencies Reg. art. 12, 13
Commercial kitchens
Kitchen hood suppression systems, gas detection and gas shut-off in kitchens in shopping centres and high-rise buildings, in catering factories and in kitchens serving more than 100 people at once. art. 57

Evacuation plan · Pro

Generate the plan for your wall from your floor plan

Shop, café, office, gym, clinic: in most countries, a workplace is expected to have an emergency plan and a visible evacuation plan; in Türkiye it's mandatory for all workplaces. You don't need to have this plan drawn separately: in Nodaform it's generated from the floor you've already drawn to scale.

  • Escape arrows, automatically. The route from each room to the nearest exit is found through the doors and drawn with green arrows.
  • "You are here" and assembly point. You mark where the plan will hang and the assembly point outside.
  • Equipment and legend. Extinguishers, hose reel cabinets, call points and emergency exits in international colours; legend, emergency number and short instructions on the sheet.
  • In 12 languages. The plan is printed in the language you use the editor in.
The Safety step in Nodaform

Place, check, get the sheet

There's a new step on the left of the editor: Safety. You place the fire equipment and choose your region and the building's use; the check scans the plan with the rules of the region you chose.

STEP 01

Place the equipment

Extinguishers (powder, CO₂, foam, class F, wheeled), fire hose reel cabinet, fire blanket, smoke, heat and carbon monoxide detectors, sprinklers, manual call point, emergency lighting and exit sign. Shown with standard symbols on the plan and at real mounting heights in 3D.

STEP 02

Run the check

Choose the region (Türkiye, Germany, England, USA) and the use (residential, office, shop and café, hotel, hospital, premises with flammable materials). Extinguisher reach is shaded by walking distance, and corners out of reach turn red. The shortest escape route and its distance are drawn from every room to an exit; rooms over the limit, extinguishers missing for the area and doors that don't open in the direction of escape are listed.

STEP 03

Get the evacuation plan

The "Evacuation plan" sheet brings together the escape arrows, equipment, You are here marker, assembly point, legend and emergency number on a single page. Download it as PDF or PNG, frame it, hang it.

For your home

Home fire safety checklist

Most home fires start in the kitchen, in the electrics or with heaters. Whether or not it's a legal requirement, going through the list below once greatly improves your family's safety.

To spot overloaded socket circuits, see Nodaform's voltage and load calculation.

  1. Smoke detector in the hallway leading to the bedrooms and on every floor; press the test button once a month.
  2. Carbon monoxide detector in the room with a combi boiler, water heater, stove or fireplace, if you have one, and near the bedrooms.
  3. Extinguisher and blanket. A small ABC powder extinguisher in the hallway and a fire blanket next to the hob; everyone in the family should know where they are.
  4. No water on a pan fire. Cover it with a lid or a blanket and turn off the hob.
  5. Sockets. Don't plug an extension lead into another extension lead; don't connect a heater, oven and washing machine to the same power strip.
  6. Escape plan. Think of two ways out of every room, pick a meeting point outside and practise once with the children.
  7. Keys and doors. Keep the key to a locked door next to the door; don't leave things in the stairwell.
  8. Check the extinguisher. Is the pressure gauge in the green? Has the last service date passed?
What it is not

It informs; it doesn't replace a fire safety design

This page and the Safety step help you ask the right questions at the start of the design and spot obvious gaps. A building's fire safety also depends on building materials, fire resistance, building services, use and operation. For building permits, occupancy permits and business licences, what counts is a fire safety design prepared by a licensed engineer and the fire department's opinion.

Nodaform doesn't hide this limit: the rule set, source and assumptions used by the check are shown in the results panel. A red warning must always be dealt with; a green result, on the other hand, doesn't mean "everything is fine".

FAQ

Frequently asked questions

Is it mandatory to keep a fire extinguisher at home?

In Türkiye, the regulation sets the number of extinguishers by area but has no separate "one extinguisher per flat" rule. In England, the fire safety order doesn't cover private homes; in the USA, extinguishers are not required in one- and two-family homes. Still, all sources recommend a small ABC powder extinguisher near the kitchen and a fire blanket next to the hob.

How often should a fire extinguisher be checked?

In Türkiye, a general on-site inspection once a year, and refilling and a pressure test at the end of the fourth year. Germany requires expert maintenance every two years in workplaces, England a yearly service and a monthly visual check, and the USA a monthly visual check and yearly maintenance in workplaces. Check the pressure gauge and expiry date of your extinguisher at home regularly.

At what height is an extinguisher mounted?

In Türkiye, 4–12 kg extinguishers are hung no higher than about 90 cm above the floor. In the USA, the top of an extinguisher up to 40 lb is at most 5 ft (≈ 1.5 m) above the floor. The guidance in England puts the handle at about 1 m for large extinguishers and 1.5 m for small ones. The common goal is for the extinguisher to be visible and within everyone's reach.

Are smoke detectors mandatory at home?

It depends on the country. They are mandatory in homes in all German states, in France and in the Netherlands; in England, they are required in rented homes and new buildings, and in Scotland in all homes; in the USA, the model code requires them in new buildings. In Türkiye, there is no national requirement for homes (except buildings over 51.50 m), but fitting them is recommended.

Why shouldn't you pour water on an oil fire?

Water that sinks below hot oil instantly turns to steam and throws the burning oil out; the flames reach the ceiling within seconds. A pan fire is covered with a lid or a fire blanket and the hob is turned off; in commercial kitchens, a class F (class K in the USA) wet chemical extinguisher is used.

Do I have to post an evacuation plan at my workplace?

In Türkiye, all workplaces prepare an emergency plan, and an evacuation plan is posted at eye level at entrances and on each floor. In Germany, an escape and rescue plan is posted if the layout, number of visitors or hazard requires it. In England, a risk assessment and an emergency procedure are required; in the USA, OSHA requires a written emergency action plan and doesn't require posting a diagram, but local codes may.

Do I have to build a fire escape stair for my apartment building?

In Türkiye, a normal stair is enough for residential buildings up to a building height of 21.50 m. Taller apartment buildings require at least two stairs, one of them protected; as the height increases, a fire safety lobby and pressurisation are added. The regulation also covers existing buildings; the deadline for fixing deficiencies that require construction work ended on 31 December 2025. The exact requirements for your building are determined by a licensed engineer and the fire department.

Which plan includes the Safety step?

Fire equipment symbols are on Plus and higher plans; extinguisher reach and travel distance checks, the findings list and the evacuation plan sheet are on Pro and Ultimate. The information on this page is open to everyone.
