Escape route signage according to ASR A2.3: specifications, obligations and audit evidence

The Technical Rule for Workplaces ASR A2.3 in the updated version from August 2007 with changes until July 2022 specifies the requirements of the Workplace Ordinance for escape routes, emergency exits as well as their marking and lighting. It supplements Section 4 Paragraph 4 ArbStättV and, in conjunction with ASR A1.3 for safety markings and ASR A3.4/3 for emergency lighting, specifies the structural and organisational obligations in workplaces. According to Section 25 ArbStättV, violations are punishable as administrative offenses with fines of up to 5,000 euros per violation, in conjunction with Section 22 ArbSchG up to 25,000 euros. In the event of damage, the breach of duty regularly leads to personal liability of the management according to § 130 OWiG and, in serious cases, to criminal liability for negligent bodily harm or death.

This article explains what specific requirements ASR A2.3 makes for the signage of escape routes, how the requirements interlink with DIN EN ISO 7010, DIN ISO 23601 for escape route plans and the model building regulations and what evidence Supervisory authorities, professional associations and property insurers expect in the audit. As a compliance platform and officer-as-a-service, CIVAC supports fire protection officers in industry, commerce, healthcare, education and administration with audit templates, appointment certificates, maintenance registers and receipts. Licence the workspace for your internal representatives or have our representatives order it. Audit-proof, documented, ASR-A2.3-proof. You will learn the minimum dimensions, the mandatory symbols and the gap list with which the audit holds.

The legal basis for escape routes and their markings arise from several sources whose scope of application overlaps. Section 4 Paragraph 4 of the Workplace Ordinance obliges employers to create and mark escape routes in such a way that safe exit from the workplace is guaranteed in the event of danger. The technical rule ASR A2.3 specifies this obligation for dimensioning, arrangement and labelling. ASR A1.3 supplements the requirements for safety markings and safety signs in the workplace. ASR A3.4/3 regulates emergency lighting as a technical safety device with requirements for illuminance, switching times and maintenance. The Annex 1 list of the ArbStättV also defines the mandatory areas.

In parallel, the state building regulations apply with their regulations on structural escape routes, which differ slightly in minimum dimensions and fire protection requirements for each federal state. For special buildings such as meeting places, schools, hospitals and industrial buildings, special regulations such as the Meeting Places Ordinance, the School Construction Directive, the Hospital Ordinance and the Industrial Construction Directive supplement the requirements. In the area of ​​dangerous goods, the ADR regulations apply, and in the area of ​​hygiene, the TRBA and the KRINKO recommendations are added, provided that rescue routes lead through areas with special requirements. Insurance conditions also often require additional VdS loss prevention standards.

The interlinking of these sources is often a cause for complaints in the audit because construction management, fire protection officers and occupational safety officers only know their parts. A complete view only emerges when the sources are brought together in a structured catalogue of measures. CIVAC maintains the relevant ASR, DIN and building code references in the workspace with version status at civac.de/roles/brandschutzanwalt and alerts you in the event of changes. This means that an ASR change, as was the case most recently in July 2022, is incorporated into the ongoing obligation without the fire protection officer having to read it from the Federal Gazette. The appointment certificate, signed, filed, verifiable.

The ASR A2.3 grades the minimum width of the escape routes according to the maximum number of people relying on them. A minimum width of 0.875 metres is permitted for up to 5 people, 1.00 metres for up to 20 people, 1.20 metres for up to 200 people, 1.80 metres for up to 300 people and 2.40 metres for up to 400 people. If there are more people, additional escape routes are required, so the dimensioning per strand applies again. The width is measured in the clear dimension between the finished surfaces; reductions due to furniture, equipment or stored goods are not permitted and are often the cause of defects in the audit.

Doors in escape routes must open in the direction of escape and must be able to be opened without external aids. Rotary knobs, lockable latches and handles on one side are not permitted in escape routes if they hinder quick exit. Sliding doors and revolving doors are only permitted in escape routes with additional safety devices. In an emergency, emergency exits must be able to be opened without a key, if necessary using panic locks in accordance with DIN EN 1125. The door fittings are subject to annual maintenance and must be included in the maintenance register.

The maximum length of an escape route to a secured area or a second escape route is generally 35 metres according to ASR A2.3, in special buildings depending on the regulations 25 or 50 metres. When designing, tripping hazards, differences in level and lighting gaps must be taken into account. CIVAC stores the measurement table in the workspace and links it to the number of employees per area. If there is an increase in staff or a change in use of areas, the minimum width requirement is recalculated and reported to the fire protection officer so that any shortfalls are identified and eliminated before supervisory contact. Others run compliance like a filing cabinet. We run it like software.

The escape routes are marked according to DIN EN ISO 7010 with standardised escape signs. The most important signs are E001 emergency exit on the left, E002 emergency exit on the right, E003 first aid, E007 emergency exit door with arrow, E013 assembly point and E022 assembly point for escape routes. The signs are green-white and photoluminescent if they are required for safety in the event of a power failure. The minimum size is based on the detection distance and results from DIN ISO 3864 with the formula height equals distance divided by a factor depending on the illuminance, usually a factor of 100 for illuminated signs and a factor of 200 for luminous signs.

The ASR A1.3 supplements the requirements for attachment. Escape signs must be installed in such a way that they are visible from every position in the escape route. They must be repeated at junctions, corner points and doors with a change in direction of escape. In corridors longer than 25 metres, repeating within sight is required. The installation height is usually between 2.00 and 2.50 metres above the finished floor, on doors directly above the lintel. In rooms with ceilings over 4.00 metres, a second sign level at a height of 1.50 metres makes sense to ensure visibility in the event of smoke gases in the ceiling.

Arrow directions must be clear. An upward arrow on an emergency exit sign always means straight ahead, not up, which is often misinterpreted in practice. DIN EN ISO 7010 contains in Annex A the permissible arrow combinations that the fire protection officer must adhere to. CIVAC provides the DIN-compliant sign library in the workspace and links it to the site plan so that when an area is converted, the signs to be updated are created as a task. The auditor calls, the evidence is ready. A gap inspection with photo evidence closes the trail and is recognised in the audit.

The emergency lighting in the escape route must be carried out in accordance with ASR A3.4/3 in conjunction with DIN EN 1838. It includes safety lighting for escape routes, anti-panic lighting and safety lighting for workplaces with particular risks. The minimum illuminance for escape routes is 1 lux in the centre line and 0.5 lux at 50 percent of the escape route width. In meeting places and special buildings, higher values ​​apply, often 5 lux. The safety lighting must reach 50 percent of the required strength no later than 1 second after the general lighting fails and be fully effective after 5 seconds. The proportional uniformity over the length of the path must be taken into account.

The minimum operating time is 1 to 3 hours, depending on the special building regulations. Places of assembly generally require 3 hours, office buildings 1 hour, hospitals 24 hours for special areas. The power supply comes from central battery systems, group batteries or individual lights with their own battery. Maintenance includes monthly functional tests with a trace of evidence, annual endurance tests and, after three or four years, the deep discharge test of the batteries. The checks are documented in the maintenance book and must be presented in the audit. A missing entry is considered a test not carried out.

Security lights in the self-testing category according to DIN EN 62034 make it easier to trace documents because they carry out the functional tests themselves and report them to a control centre. However, responsibility for maintenance remains with the operator; documentation of self-checks is mandatory. CIVAC integrates the maintenance register in the workspace and links the luminaires with the site plan. Battery life expiration reminders are set 60 days before the deadline so that maintenance partners can be engaged in a timely manner. Audit-proof, documented, ASR-A3.4/3-proof. This structural guidance closes the most common gap in emergency lighting, the missing maintenance documents.

The escape route plan, also known as the escape and rescue plan, must be designed in accordance with DIN ISO 23601. It shows the floor plans with escape routes, emergency exits, first aid facilities, firefighting equipment and the current location of the viewer. The symbols correspond to DIN EN ISO 7010, the scale is between 1:100 and 1:350 depending on the size of the system. The plan must be carried out in colour with green emergency signs, red firefighting signs and blue mandatory signs. The minimum size is DIN A3, in larger systems DIN A2 or DIN A1. The labelling must be carried out in several languages ​​if employees or visitors do not understand German sufficiently.

Posting obligations result from § 4 ArbStättV and ASR A2.3. Plans must be posted in clearly visible locations such as entrances, stairwell landings, elevators and on every floor. In accommodation establishments, they must also be displayed in every accommodation room, and in hospitals in every patient area. The plans must be checked at least annually to ensure they are up to date and updated after any significant structural changes. Any omission of the update is immediately apparent in the audit because the plans are marked with a version date. Outdated plans are a standard defect in supervision.

Responsibility for posting lies with the employer, coordination with the fire protection officer. CIVAC maintains the escape route plan in the workspace with version status, posting locations and updates. During a renovation, the plan is renewed and all poster locations are recorded as a to-do list with a delivery date. The caretaker or facility management confirms the attachment with photo evidence, which is saved in the workspace. The appointment certificate, signed, filed, verifiable. This creates a continuous track from the structural change to the updated notice on site, without anyone maintaining Excel lists or PDF email attachments. Versioning ensures audit reliability over several years.

The appointment of a fire protection officer is not formally required in all industries, but in many cases it results from the fire protection concept, the building regulations of the federal states, the special building regulations and the insurance conditions. The function is mandatory in meeting places with 200 seats or more, in hospitals, in industrial buildings of defined sizes, in high-rise buildings and in buildings with particular fire risks. DGUV Information 205-003 describes the tasks and qualification requirements in detail. The professional association and the insurers check the appointment as a minimum requirement for insurance coverage and reduce benefits if the position is only formally filled.

The list of tasks of the fire protection officer covers twelve areas. Firstly, the creation and maintenance of the fire protection regulations parts A to C according to DIN 14096. Secondly, the participation in the fire protection concept. Thirdly, coordination with construction management and experts. Fourth, maintaining the escape route plan. Fifth, the annual fire safety instructions. Sixth, the maintenance of fire protection equipment with a receipt track. Seventh, the evacuation drills at least every two years. Eighth, the interface to the fire department and the supervisory authority. Ninth, participation in risk assessments. Tenth, the investigation of fires and near misses. Eleventh, the reporting line to management. Twelfth, participation in audits.

The position requires professional qualifications according to DGUV with at least 64 teaching units and regular training. CIVAC bundles the tasks at civac.de/roles/brandschutzanwalt in the workspace with appointment certificate, task catalogue, maintenance register and training register. Licence the workspace for your internal representatives or have our representatives order it. For vacancies or multi-location structures, CIVAC takes over the function as officer-as-a-service with the CIVAC SLA of 2 working days. Deadline begins as soon as we become aware of it. This structural connection protects management from personal liability in the event of sudden vacancies or illnesses.

Evacuation drills are required in most special building regulations at least every two years, and in places of assembly and schools they are often required annually. They must be agreed with the supervisory authority and the fire department and documented in writing. An evacuation exercise includes triggering the evacuation alarm, leaving the workplace via the escape routes, checking the assembly point and evaluating the evacuation time. Depending on the special construction, minimum target values ​​are between 3 and 8 minutes for complete evacuation. Exercises without evaluation are standard gaps in audits and lead to complaints because their effectiveness has not been proven. The evaluation belongs in the exercise protocol and is mandatory.

Fire protection instructions for employees must be carried out at least annually in accordance with Section 12 of the ArbSchG. They include the location of escape routes, the use of firefighting equipment, behaviour in the event of a fire and the meeting point convention. Participation is documented with date, content and signature. For new employees, the training must be provided before starting work. In multilingual workforces, translations and comprehension tests are mandatory if German is not sufficiently understood. Collective instruction without an individual receipt is vulnerable to an audit and does not suffice as evidence.

Fire protection assistants according to ASR A2.2 supplement the fire protection organisation. Depending on the industry, the number is 5 percent of employees in standard risks and higher in special risks. Fire protection assistants are trained in a two-day course and refreshed annually. CIVAC maintains the register of helpers in the workspace with orders, proof of training, refreshers and replacement plans. Audit-proof, documented, § 12 ArbSchG-proof. When there are changes in employees, gaps automatically become visible and the fire protection officer can make adjustments before the target number falls below the target number. This means that employee participation remains structurally stable, even in phases of high fluctuation.

In German workplaces, three gaps in escape routes are particularly common. Firstly, blocked or restricted escape routes. Furniture, stored goods, printers, stacks of paper and temporary structures reduce the minimum width required by ASR A2.3. In audits, minimum widths are often measured during ongoing operations, so that historically harmless situations become a breach of duty over time. A regular inspection with photo documentation reveals the gaps before the supervisor finds them. Particularly in storage areas, printer rooms and workshops, there is a great temptation to use escape routes as space for temporary storage.

Secondly, the lack of maintenance records. Emergency lighting, fire doors, fire alarm systems, smoke extractors and fire extinguishers require regular maintenance at defined intervals. The receipts are often distributed by facility management, by an external maintenance partner or in an individual person's mailbox. A summary maintenance calendar is then missing from the audit. Thirdly, outdated escape route plans. Plans are often not updated following renovations, furniture changes or new signage. The difference between plan and reality is immediately noticeable in the audit because supervisors compare the plan with the actual system and note deviations directly.

CIVAC closes these gaps in the workspace structurally. The inspections are carried out using templates and photo documentation is stored. Maintenance appointments are managed centrally, reminders are set 60 days before expiration, and maintenance partners are assigned standardised orders. Escape route plans are linked to structural changes and are renewed with each change. The auditor calls, the evidence is ready. This means that the escape route organisation does not remain in the memory of individual employees, but rather in a searchable compliance trace that can be checked in the audit without advance notice. This structuring significantly reduces the follow-up costs of audit follow-up because defects are processed without supervisory pressure and outside of escalation.

An escape route system that complies with ASR A2.3 is not the result of one-off signage, but of ongoing organisation. Structural changes, furniture changes, staff growth and product range adjustments continually change requirements. If you don't manage the movement in one platform, you lose the overview and audit security. Regulatory authorities, professional associations and property insurers examine the maturity of the organisation, not just the individual sign or emergency light. A platform alone, without an appointed fire protection officer and without a reporting line, provides no more protection than an order without tools.

CIVAC is a compliance platform and officer-as-a-service with workspace, audit templates, appointment certificate, reporting line and EU data residency. Licence the workspace for your internal representatives or have our representatives order it. The workspace lists escape route measurements, signage, emergency lighting, escape route plans, maintenance documents, exercises, instructions and fire protection assistants in a searchable structure. The auditor calls, the evidence is ready. The CIVAC SLA of 2 business days replaces the usual response window of 2 to 6 weeks when unannounced audits, modifications or incidents catch the organisation off guard. The interface to the fire department and supervision is structurally included in the workspace.

If you want to have your escape route organisation checked for ASR A2.3 conformity for the first time or want to fill the role of fire protection officer, we will clarify this in a structured initial meeting. Turn reading into an assignment. Write to info@civac.de or use the contact form to arrange an initial assessment of your current fire protection organisation. You will receive a concrete list of gaps with delivery dates and priorities so that the escape routes do not become a risk position in the next audit, but remain part of a resilient fire protection organisation that is responsible in the event of an emergency and protects the management from personal liability.
