Are ISO 7010 Fire Exit Signs Mandatory in the UK?

A fire risk assessment identifies an escape-route signage gap, but the building still has old-style running-man signs in place. Are ISO 7010 fire exit signs mandatory? In most UK workplaces and public premises, the legal duty is to provide suitable, clear fire safety signs where they are needed. ISO 7010 is the recognised current standard for the symbols used, so it is normally the right specification for new, replacement and upgraded fire exit signs.

The distinction matters. ISO 7010 itself is a standard rather than an Act of Parliament. However, a responsible person or employer must make sure people can find and use escape routes safely. Choosing recognised ISO 7010 fire exit signs is the practical, consistent way to meet that duty and reduce uncertainty during an evacuation.

What UK law requires for fire exit signs

For most non-domestic premises in England and Wales, the Regulatory Reform (Fire Safety) Order 2005 places duties on the responsible person. Scotland and Northern Ireland have their own fire safety legislation, but the same core expectation applies: escape routes must be safely managed and people must be able to evacuate.

The Health and Safety (Safety Signs and Signals) Regulations 1996 also require safety signs where a significant risk cannot be avoided or controlled adequately by other measures. Fire safety signs are part of this wider requirement. Whether signs are necessary, and where they should be positioned, should be determined through a suitable and sufficient fire risk assessment.

That does not mean every door needs a fire exit sign. In a small, familiar office with a plainly visible final exit, additional signage may add little value. In a warehouse, school, hotel, workshop, communal building or multi-room workplace, the route may be less obvious, may change direction, or may be used by visitors. Clear signs become essential.

Why ISO 7010 is the normal specification

BS EN ISO 7010 sets out registered graphical symbols for safety signs, including the familiar green emergency escape symbol. The symbol shows a person moving through a doorway, with an arrow used to indicate the direction of travel where required. The common emergency exit symbol is known as E001.

The purpose is immediate recognition. People may not read English fluently, may be unfamiliar with the building, or may be dealing with smoke, noise and alarm activation. A consistent pictogram gives occupants a better chance of interpreting the route quickly.

Older fire exit signs can use different running-man designs, text-only messages or symbols combined in inconsistent ways. They are not automatically illegal simply because they are older. The key test is whether your existing arrangements remain suitable, visible, understandable and appropriate to the risk. Yet when a sign is being replaced, a site is refurbished, or a new escape route is introduced, ISO 7010 is the sensible standard to use.

Are ISO 7010 fire exit signs mandatory for existing premises?

There is no blanket rule saying every existing fire exit sign in every building must be replaced overnight solely because it is not ISO 7010. A risk-based approach applies. If an existing sign is clear, well positioned, maintained and forms part of an effective means-of-escape strategy, immediate replacement may not be necessary.

That said, retaining a mixture of old and new styles can create avoidable confusion. A premises with some text-only signs, some older running-man symbols and some ISO 7010 signs does not present a consistent visual instruction. This is particularly relevant where staff change regularly, visitors are frequent, or the building has a complicated layout.

Replacement should be prioritised where signs are damaged, faded, obscured, poorly lit, incorrectly directed or no longer match the escape plan. It also makes good operational sense to standardise signs during planned maintenance rather than wait until an enforcement visit or incident exposes the weakness.

When fire exit signs are needed

A fire exit sign should lead occupants towards a safe escape route or identify a final exit. The signs need to be placed so that someone moving through the premises can follow the route without hesitation. This commonly includes corridor junctions, stairways, changes in direction, exits from larger rooms and doors leading to a place of ultimate safety.

The sign must show the correct direction. An arrow pointing left or right should reflect the route a person needs to take from their viewing position, not simply the side of the door on which the sign has been fitted. This sounds straightforward, but incorrectly specified arrow signs are a common site error.

Doors that are not part of the escape route can need separate control. For example, a door that leads to a cupboard, plant room, dead end or restricted area should not be mistaken for an exit. Depending on the risk assessment, additional signs or access control may be required to prevent people being directed into an unsafe area.

Escape route signs are not the same as fire equipment signs

Green emergency escape signs show where to go. Red fire equipment signs identify firefighting equipment such as extinguishers, hose reels and fire alarms. Blue mandatory signs may instruct occupants to keep a fire exit clear. Each sign type has a separate purpose, so a fire risk assessment should consider the complete signage arrangement rather than buying signs one at a time.

Selecting the right ISO 7010 fire exit sign

Start with the route plan, not the product format. Walk every escape route from the point of view of a visitor who has never used the building. Check what they would see at each decision point, including from within offices, production areas, stock rooms and shared corridors.

A practical signage check should cover:

• the final exits and every point where the route changes direction;
• the correct running-man symbol and arrow direction;
• sign size and viewing distance for the location;
• lighting conditions, including what happens if normal lighting fails; and
• fixings and materials suited to indoor, outdoor, temporary or demanding industrial use.

Photoluminescent fire exit signs are widely used because they remain visible for a period after the lights go out, provided they receive sufficient ambient light to charge. They can be a useful part of an emergency lighting strategy, but they do not replace the need for suitable emergency lighting where that is required by the risk assessment.

Material choice also affects the result. Self-adhesive vinyl may suit clean internal doors and smooth walls. Rigid plastic signs are a dependable option for most workplaces, while more durable materials may be appropriate for exposed locations, construction environments or areas subject to impact and frequent cleaning. The important point is that the sign remains legible and securely fixed for its intended service life.

Common mistakes that create compliance problems

The biggest issue is often not the symbol itself but poor placement. A compliant-looking sign above a door is of little use if it cannot be seen from the approach route, is hidden by an open door, or directs people towards an alternative route that is no longer available.

Another mistake is relying on wording alone, such as "Fire Exit" or "Exit", without a recognised pictogram. Text may assist where appropriate, but a standard ISO 7010 symbol provides clearer universal communication. Avoid adding unofficial graphics, branding or excessive wording that weakens the safety message.

Signs should also be reviewed whenever the building changes. New partitions, racking, machinery, furniture, security doors and altered room layouts can all block sightlines or change the most suitable escape route. A sign scheme that was correct last year may no longer be adequate.

A practical approach for responsible persons

Use the fire risk assessment as the starting point, then record the escape routes and inspect them routinely. Where new signs are needed, specify ISO 7010 emergency escape symbols in a consistent size, finish and layout across the site. This gives staff, visitors and contractors one clear visual language to follow.

For buyers managing several premises, standardising the sign range also makes future replacement simpler. The Sign Shed supplies a broad range of ISO 7010 fire exit signs, including directional arrows, final exit signs and photoluminescent options, helping sites source consistent signage without unnecessary delay.

If there is any doubt over whether a route requires a sign, treat it as a fire risk assessment question rather than a product question. The best fire exit sign is the one that gives a person clear direction at the exact moment they need it.
