5 Fire Safety Elements for Commercial Buildings

It is incredibly important to maintain fire safety in a commercial building. It’s important as it keeps your customers safe, as well as yourself and your employees. It’s crucial to maintain fire safety equipment and to make sure that your building covers fire laws.

Commercial fires can be caused by the same reasons that domestic fires can, such as ovens, faulty electrics, arson etc. However, the good news is that these fires can be prevented, and measures can be taken to ensure that the building is as safe as it can be.

Use of fire alarms

Fire alarms are an incredibly important part of fire safety as they are the warning signal to people to exit the building. Fire alarms are arguably, the most important feature in a fire safety system. Fire alarms are used as they usually detect a fire the earliest.

However, you are not actually required by law to have a fire alarm system on the premises, it is typically the easiest and most convenient system to have. Although the law states that you do not have to have a fire alarm system in the building, you must have an appropriate fire detection system in place.

Exit Signs

Exit signs are another crucial part of fire safety in a commercial setting. This is because people need to know where to go in the event of a fire. Having signs that clearly point to the exit, is crucial. If people do not know here to go, then a panic will ensue. These kinds of panics can sometimes be fatal as people tend to not think logically. It’s imperative that people remain calm when there is a fire, as it can mean the difference between life and death. Therefore, exit signs are so important.

Emergency lights

Emergency lights are also incredibly important to use alongside exit signs. During a fire, there is typically a lot of smoke. This can obscure vision and make the setting extremely difficult to navigate around, even in a familiar setting. Therefore, emergency lights are important, as they can guide people to the exit. They are easier to see through the thick smoke. Furthermore, light up exit signs switch to emergency power when it cannot connect to the main power.

Fire extinguishers

A lot of commercial buildings have fire extinguishers nearby. However, you must know how to use one in order to operate it. Usually, the operation of these is included within fire safety training.

Fire extinguishers should also not be any further than 75 feet away from each other, as people should not have to travel more than this in order to reach a fire extinguisher. They should also be stored near the exits, as people coming in should not have to travel far to reach one to put out a fire.

Fire sprinklers

A lot of the time in commercial buildings, a sprinkler system will be used. This can be an effective way to reduce a fire, or even stop a fire. These systems require regular maintenance and upkeep by licensed inspectors.

Eco friendly materials

Eco-friendly wood materials for fire protection

There is an increasing demand for eco-friendly materials to be used wherever they can due to the current climate crises. Is this actually what’s good for your construction though?

The requirements of fire protection materials

First of all, there are many requirements that need to be met when using eco-friendly materials. Safety is of the utmost importance when it comes to fire protection, so companies have a responsibility to make sure that the materials that they are using to build with are safe to use and will remain safe throughout the building’s life cycle.

In any building structure, compartmentalising can make the building much safer in the event of a fire and compartmentalising buildings should be the standard practice whenever building any structure. This method can be useful as it can restrict the spread of a fire.

In order to make a wood building fire resistant, internal cladding and linings should be used in the compartments. Also, cavity barriers should be positioned in the external cavity walls of a timber frame structure as this can also prevent a fire spreading through the concealed cavities of a building. You can read more on this here.

Using wood for fire-protection

Surprisingly, wood can actually be a good fire retardant material because its properties are well-known, and it is known how wood typically reacts in a fire. The charring properties of wood can prevent a structure from collapsing. It has been known that wood chars evenly at a rate of about 1 millimetre per minute. Being able to predict how a material will react in the event of a fire can be invaluable. This allows the emergency services to be able to formulate a plan to combat the fire as they know what’s going to happen and the speed at which the fire is likely to spread.

There is actually an 18-storey timber-frame building in Norway that is the tallest timber frame building in the world!

Eco-friendly material

Eco-friendly materials can have different descriptions based on personal opinion and personal passion. In general terms, eco-friendly refers to being good or bad for the environment, but it can have complex discussions surrounding the issue.

Wood, when being used to build with, requires treatments to make it fire-retardant. A lot of these treatments can be toxic, which is not good for the environment, or good for human health. However, there has been a lot of research conducted more recently on toxic and non-toxic treatments for wood.

Treatments for wood protection have been used ever since timber was first used by man. Some conventional timber treatments would include oil or wax, such as linseed, beeswax and tung oil. These are regarded as eco-friendly materials. In more modern times though, wood treatments have been more reliant on harsh substances and chemicals. Creosote (made from coal tar), for example, used to be a popular wood sealant. It was later found out that Creosote is carcinogenic, so as of 2003, it has been banned in Great Britain to the general public. A lot of these harsher methods for wood treatment have now been banned.

How can the eco-friendly wood materials help with fire protection?

The eco-friendly treated wood releases water vapour while burning, which decreases the combustion temperature, slowing the spread of fire, thus proving that eco-friendly materials are generally safer. Not only are eco-friendly materials safer for the environment, but they are safer for human health too.

Fire protection

Fire Protection for New Buildings

The principal method of fire stopping and damage limitation is achieved through compartmentalising a building. This involves the installation of fire-resistant walls, floors and ceilings.
In the last 10 years the UK has seen a 37% reduction in fires that require the assistance of the fire service. This has also resulted in a 27% drop in the number of casualties. The decrease can be partly be attributed to the advancement of fire protection methods that stall the spread of fires to enable the safe evacuation of occupants to the building, provide an early alert and prevent ignition. Despite these positive number, 68,871 serious fires were recorded in 2019 meaning that there are still improvements to be made in fire safety to protect and preserve life.
Construction companies have an obligation to incorporate fire safety into the design and construction of buildings. So, what requirements need to be met, how is the risk evaluated and which protection methods should be installed?

Fire Protection and the Law

The Regulatory Reform (Fire Safety) Order 2005 applies to every building used for the public and as workplace. The law states that a designated responsible person with a level of control over the building must take reasonable steps to reduce the risk of fire and to ensure safe evacuation of all people occupying the building should a fire break out. Part B of the Building Regulations covers residential dwellings through several requirements such as the use of adequate fire warnings and escapes, the installation of passive fire protections to stop the spread of external and internal fire and the presence of access for fire services. Compliance of these regulations is the very minimum to ensure fire safety in buildings and also applies to the health and safety requirements during the construction of the building.

Risk Assessing

Before applying fire protection strategies to any building, the risks must be identified. A full fire risk assessment must be carried out at the design phase. It should then be repeated during construction to ensure fire safety measures are being included and then again before the building is handed over to the client. The final assessment demonstrates compliance and aids the building owners in enforcing fire protection once they become responsible.
A fire safety risk assessment should include:
  • Fire risks including potential ignition points, flammable materials or areas that could fuel or help spread a fire.
  • What risk it poses to people. It must include any vulnerabilities people have that would inhibit their safe evacuation from a fire, lone workers or groups of people working with combustible materials.
  • The solutions put in place to minimise the risk.
  • A plan for emergencies such as escape routes and access for fire services.
  • A review and checking procedure to ensure that fire safety is a high consideration.

Active and Passive Fire Protection

Once the fire risk assessment is complete and hazards have been mitigated, plans should be made to minimise the impact of any remaining risks. To do this, active and passive fire protection systems need to be in place. Both of these measures provide the building with measures to fight a fire and prevent it from spreading. Architects and contractors must work together to implement these measures into the design of a building and maintain them to deliver continued protection.

Active Fire Protection

Active fire protection is the term given to fire safety measures taken to fight fires after they have started. They are a powerful and essential line of defence for all buildings. Active systems include sprinklers, fire extinguishers and automatic dousing systems. Designers should consider each system to the building using water, foam, powders or gases to stop a fire in the quickest and safest way.

Alarm systems are also a powerful fire protection tool that are imperative to the fire safety of a building. Fire alarms alert occupants immediately to a threat which means action can be taken quickly.

Passive Fire Protection

Passive fire protection is imperative to preventing the spread of a fire. Passive measures resist the fire, compartmentalise its impact, protect the structural integrity of the building and provide vital time for people to evacuate. They are referred to as passive measures because they require no action in order to work.

Passive measures are usually installed in the structure of the building. They are built into walls, ceilings and floors and provide the following benefits:
  • Structural support
  • Heat insulation
  • Reduction of the spread of gas and smoke
Passive fire protection plans require a range of measures to work together to provide the best defence.

Common passive fire protection installations include fire doors, partition glazing, cavity barriers and gap seals. Passive measures can also be found in the foundations of buildings in the form of concrete, bricks and gypsum plasterboard. This is also used to protect structural stability of the building and compartmentalises fires. Some measures can offer up to four hours of protection allowing time for firefighters to arrive and tackle the blaze.

Dampening is another important passive fire protection tool. Ducts, pipes and cables provide hidden passage for fire and smoke to spread which is usually gone unnoticed. It is essential to include fire and smoke dampeners when installing heating, ventilation and air conditioning units. Proper maintenance of these installations is needed for the measures to be effective.

Planning Evacuation

A key part of a fire protection plan is to design a safe evacuation route. All occupants of the building must be able to leave quickly and safely in the event of a fire. Alternatively, architects should design fire-proof areas for those that aren’t able to evacuate. These spaces are designed to protect people until the fire service arrive. When planning an escape route, maximum capacity of the building, consideration of the mobility needs of the building users and access for firefighters are essential.
