Fire Safety in Office Blocks: Common Risks and How Businesses Can Stay Compliant

Office buildings are amongst the most common forms of commercial properties. They pose a significant fire risk due to the high concentration of people and equipment they contain. Many office buildings also have multiple floors or annexes, making evacuation more complex in the event of a fire. Some office buildings are also attached to industrial or manufacturing operations, which present additional fire hazards and increase the overall fire risk.

Here are the top legal responsibilities of a business managing fire safety in an office environment, the most common fire risks and how businesses can proactively manage them.

The legal responsibilities for managing fire safety in an office building

The Regulatory Reform (Fire Safety) Order 2005 is the main piece of legislation regulating fire safety in commercial buildings in the UK. To comply with the order, and regardless of the size or nature of the office-based operations, businesses must have the following measures in place:

A fire risk assessment
A nominated ‘responsible person’
A team of appointed fire wardens or marshals
Fire safety training for this appointed team
Appropriate fire safety signage throughout the site
Suitable fire extinguishers located throughout the site

In most cases, an office will also need a fire alarm system, emergency lighting and fire doors. The exception is very small, single-occupancy offices where all activities are non-hazardous, and the entire space is visible at all times.

Common fire safety failings in office buildings

According to the London Fire Brigade, the most common causes of fires in office environments are electrical distribution (32%), lighting faults (14%) and smoking-related incidents (11%).

Electrical distribution – Overloading sockets, damaged equipment, leads or wiring and poor overall electrical maintenance.
Lighting – Loose connections, outdated wiring and power surges can all contribute to fire issues with lights, alongside poor installation and poor-quality products.
Smoking – Careless disposal of smoking materials.
Housekeeping – Allowing combustible materials to accumulate near heaters, electrical panels or designated smoking areas.
Fire doors – Not keeping fire doors shut allows smoke and flames to spread, which can prevent safe evacuation of an office building.
Appliances – Faulty appliances or poor maintenance of appliances, such as IT equipment, toasters, ovens, microwaves or kettles.
Emergency plans – No plans in place, or plans are not practiced, thought-through or risk assessed.

The importance of maintaining fire alarms and emergency lighting

The employer in an office environment is legally responsible for providing and maintaining both a fire alarm system and emergency lighting. These measures are essential for legal compliance and, more importantly, help protect people, equipment and property. They also support safe evacuation by reducing panic and providing clear escape routes during a power failure or reduced visibility.

Maintenance of a fire alarm system is essential because these controls provide an important early warning system, which detects smoke and fire immediately and therefore provides the building occupants with sufficient time to escape the building before serious fire and smoke takes hold Businesses should ensure these systems remain reliable and fully operational in an emergency. This means systems are free of dust and dirt, are not damaged and have been tested as part of routine maintenance and evacuation procedures. Businesses have a legal duty to maintain fire safety equipment in good working condition, so it is essential maintenance of fire alarm and emergency lighting systems takes place.

Staff training and evacuation procedures

Although commercial office buildings are required to have a team of nominated fire marshals, who have a specialist duty to take action in the event of fire, all staff are required to have a basic knowledge of fire safety. This can be provided through induction procedures, permanent notices, weekly drills and regular safety communications. The core requirements of basic staff training on fire safety should include:

How to activate the fire alarm in the event of a fire
How and when to use fire extinguishers and other fire safety equipment
How to be aware of and prevent fire safety hazards in the office
Evacuation procedures – what to listen for, where to go, how to act, what your responsibilities are

How proactive fire safety measures can protect businesses and occupants

Carrying out fire risk assessments and the installation and maintenance of a fire alarm system are the primary fire safety controls an office building should be managing. These proactive measures help reduce fire risks and minimise the likelihood of a fire occurring. Proactive fire safety measures should therefore involve:

Fire risk assessments – To identify fire hazards in a building and create an action plan to address and control them.
Fire alarm systems – Smoke and heat detection systems that identify signs of fire and alert occupants to evacuate safely.
Fire alarm system maintenance – Testing and servicing the fire alarm system regularly to ensure it is always in good working order and effectively alerts all office building occupants. Service and maintenance practices should also be extended to emergency lighting and fire extinguishers.
Emergency plans – Effective escape routes and protocols which are clear and regularly practiced by all employees.
Company procedures – Strict rules in place for issues such as smoking, housekeeping, fire doors and electrical safety.
Staff training – Effective staff training on all basic fire safety responsibilities.
