Emergency exit! – Get to know the BS EN 1125 is a great Locks Online guide, explaining how the British Standards for panic and emergency exit doors will affect any business.
Get to know the BS EN 1125 and what procedure you must take to ensure your emergency exit complies with the right standards.
Whether you have an emergency exit door in your shop for customers, or have one in the office for 100 employees, it is important to have the correct standards on your panic and emergency exit devices to ensure all health and safety is followed. It’s not as easy not to just fix up a door and place a green arrow above it. There are lots of rules and regulations you must follow for insurance purposes and of course, for safety of visitors and staff. In this guide I am going to break down and explain what you need to measure and look out for when designing and building a new fire exit.

There are 2 parts to the BS EN 1125. This one is mainly for Panic exit devices. These relate to all escape routes for buildings. From experience, general safety have made it a priority for any emergency exit door to have a horizontal panic bar which in the industry in known as ‘crash to exit’. They are designed so that if there is a situation that involves a need for a quick exit, it’s an easy escape route should there be a rush of people. This is to ensure any crowd will not be crushed if Panic arises. The pain purpose of this standard is to give an efficient and a safe escape through a door way with little or minimum effort, with no need of prior knowledge. This is aimed for locked doors on fire routes where panic situations are likely to happen.
The second part is the BS EN 179. This is for emergency exit devices. This standard is in place to ensure all devices in an emergency situation, are designed for easy use. This will therefore create less panic for people should they be put in this position, and ensuring people can get out fast and efficiently without any accidents. The main purpose of the performance requirements of this standard is to have an efficient yet safe means of escape through a doorway with one single operation. It covers the escape that needs prior knowledge of the operation of the device, which is considered great use for locked doors on escape routes, where a panic situation is less likely to happen.

Breaking down the Classifications.
BS EN 1125 and BS EN 179 use the usual coding system as with all the British Standards. This is to break down the classification for the everyday person to understand what is needed. This standard uses a 10 code system which is slightly larger than other standards. This code is presented in a line of boxes that cover a test rating for corrosion, category of use and much more. Each box represents 1 digit and each digit covers 1 feature. It will also have a small icon or image, the grade or type and the range or options that are in each digit. This probably sounds very confusing but once you get your head around how to use the classification codes, it’s VERY easy to read! So I’ll give you a helping hand as much as I can to explain these below!
What are the digits of the classification?
Digit 1 – Category of Use – 1 Grade Identified
Grade 3 – High frequency of use by public and others with little incentive to exercise care.
Digit 2 –Number of Test Cycles – 2 Grades Identified
Grade 6 – 100,000 Cycles
Grade 7 – 200,000 Cycles
Grade 5 – Up to 100kg
Grade 6 – Up to 200kg
Grade 7 – Over 200kg
Digit 4 – Fire Resistance – 3 Grades Identified
Grade 0 – Not approved for use in fire/smoke door assemblies
Grade A – Suitable for use on smoke door assemblies, subject to satisfactory assessment of the contribution of the panic/emergency device to the smoke resistance of specified smoke door assemblies.
Grade B – Suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the contribution of the panic/emergency device to the fire resistance of specified fire/smoke door assemblies.
These assessments are from the BS EN 1634-1.
Digit 5 – Safety
All panic and emergency devices have a critical safety function therefore only the top Grade 1 is identified.
Digit 6 – Corrosion Resistance – 2 Grades Identified
Grade 3 – High resistance (96 salt spray hours)
Grade 4 – Very high resistance (240 salt spray hours)
Digit 7 – Security – 4 Grades Identified
BS EN 179
Grade 2 – 1,000 N
Grade 3 – 2,000 N
Grade 4 – 3,000 N
Grade 5 – 5,000 N
BS EN 1125
Grade 2 – 1,000 N -panic devices are primarily for the operation of a door from the inside. Safety considerations will always be given priority over security.
Digit 8 – 2 Grades Identified.
Grade 1 – Projection up to 150mm (large)
Digit 9 – Type of device – 4 Categories Identified
BS EN 179
Type A – Emergency device with leaver handle operation
Type B – Emergency device with push or pull pad
BS EN 1125
Type A – Panic device with push bar operation
Type B 0 Panic device with touch bar operation
Digit 10 – Field of application
Here is an example of a classification.
As you can see this shows a panic device that has been tested up to 200,000 cycles, up to 200kg, suitable for fire door use with very high corrosion resistance with standard bar projection for use on single and double doors.
The marking from the manufactures name or trade mark must be visible on the product as well as an identification number of the certification body. A CE Mark symbol must also be present. Other marking that must be visible before fitting are
- Classification code for the product
- The number and year of the Standard
- The month and year of final assembly by the manufacturer, which can be in coded form
As you can see there are a few variations regarding what emergency and panic devices you can have and where you can place them. It is important to remember the safety of your visitors and staff. Make sure you use this guide when looking to replace or design a new emergency exit. Don’t get penalised by insurance companies for not following the right procedures.
