Why do I need Passive Fire Protection?

Protect People and Assets and Achieve Compliance

Passive fire protection (PFP) plays a vital role in the fire safety of buildings. It is designed to withstand smoke and fire for a pre-determined time by providing fire resistance. It is important that the responsible person for the building understands their duty under UK statutory law regarding fire stopping regulations and fire door regulations.

Passive fire protection is achieved through compartmentation which is provided by fire resisting elements such as floors, fire doors and walls.  The fire resistance of the materials used protects the building from structural damage which can aid evacuation of personnel in an emergency.

When a penetration occurs through a fire resisting element such as a wall, fire stopping products and or repaired fire doors are used to reinstate the integrity of the fire resisting element. It is highly recommended that all passive fire protection work, inclusive of fire stopping, fire door installation fire door inspection and maintenance and fire dampers is carried out by certified passive fire protection specialists.

Passive Fire Protection Characteristics

Passive fire protection is designed to aid with fire compartmentation by isolating the spread of fire and smoke to other parts of the building, effectively keeping the fire in the location where it originated. It is important to note that the fire rating of the materials used will determine how long they can withstand fire and smoke. For example internal fire doors will have an FD rating such FD 60 which means they are designed to withstand smoke for 60 minutes. The fire protection is required to allow people and or firefighters to access and egress a building safely in a fire. Moreover, damage to equipment and assets can be reduced if fire compartmentation is not breached.

Passive fire protection represents an important function in fire safety, so much so that it is now part of the structural integrity of buildings. The Building Regulations 2019 edition, Fire Safety, Approved Document B – Requirement B3, Internal Fire Spread (structure) state “The building shall be designed and constructed so that, in the event of a fire, its stability will be maintained for a reasonable period.” Approved document B also states that all fire-rated elements must be reinstated once penetrated by services such as cables, pipes or ducting.

As opposed to active fire protection, passive fire protection is not electronically or manually initiated such as fire extinguisher or a fire blanket. See our blog for more details on the differences between active and passive fire protection.

Fire Stopping Case Studies

Examples of Passive Fire Protection:

The following gives a brief summary on the products and examples of passive fire protection, the hyperlinks will provide more information:

  • Firewalls are used to divide a building to prevent fire form spreading by providing compartmentation
  • Fire protecting steel work is used for structural passive fire protection in the construction of new buildings
  • Fire doors are a critical part of passive fire protection in buildings because they stop the spread of fire and smoke and allow people to exit buildings through escape routes safely.
  • Fire Door hardware inclusive of ironmongery is tested for fire resistance as a complete fire door set. They should be fire resistant for the specified FD period, such as FD (60) which provides 60 minutes of passive fire protection
  • Fire resistant glass is sometimes called fire rated glass or gazing, it is designed to provide protection from fire for a set time
  • Fire rated floors provide passive fire protection for separating floors
  • Firestops are physical fire rated barriers that prevent the spread of smoke and flames
  • Fire dampers are used to provide passive fire protection for heating, ventilation and cooling systems. They are initiated by a thermal element that melts in afire and closes the damper to prevent the fire and smoke travelling through the ductwork
  • fire proofing is used to make materials such as walls fire resistant, one example of this is spraying steel to provide increase the fire rating
  • Intumescent Sealant can be applied to fire doors, windows, pipes, joints and other small holes. They create a fire barrier to stop the spread of smoke and fire
  • Pipe wraps and collars Pipe wraps and collars are designed for use on plastic pipes that pass-through floors and walls. They have an intumescent material which expands inwards to squeeze the pipe, collapsing it until the opening is completely sealed.
  • Fire batts are often coated in ablative material and it is used to reinstate the fire integrity of a wall or floor
  • Fire protection compound is used for service penetrations and is usually used to fire stop around electrical services such as cables

Is Passive Fire Protection only required in Commercial buildings?

Fire Protection is an essential requirement for all buildings. Whether they are domestic or non-domestic buildings, Passive Fire Protection is crucial to compartmentalising the spread of fire.

All new builds, extension works, or modernisations must comply with The Building Regulations 2010, Fire Safety, Approved Document B.

Why is it essential to use certified fire protection products?

It is vital to use certified and tested products and have them installed by an accredited company. Each fire stopping product is crucial to your fire safety systems and creates a barrier that slows the spread of fire.

Using certified products means that they have been rigorously tested, which gives confidence that the product is fit for purpose and will perform following all relevant legislation and regulations.

Who is responsible for Passive Fire Protection?

Businesses and landlords must meet Building Regulations, ensuring people can evacuate a building safety in the events of a fire and the building will not collapse. The legislation gives responsibility to building owners, occupiers, managers, and designers to ensure regular fire risk assessments are carried out. ClearView provides fire risk assessments that meet the regulations set out in current legislation and British Standards, including an evaluation of the protection provided. It is advised that the specification from the original building should include a clear fire protection strategy and contains the components that have been installed. If significant changes are made to the fire protection strategy, then it must be revised by a competent third party.

What is the difference between passive and active fire protection?

For a fully comprehensive Fire Protection strategy, passive fire protection works in combination with active fire prevention. While passive fire protection is built within the building such as Fire doors and Fire-resisting walls, floors, ceilings, and ducts to prevent the spread of smoke and fire, active fire protection consists of manual or automatic products that require intervention to work.

This includes products such as fire detection and alarms, fire extinguishers, door releases and fire sprinklers. Therefore, active fire protection is the act of detecting and stopping the fire, and passive fire protection prevents the spread of fire.

Why must fire door maintenance be carried out?

It is essential to carry out regular fire door maintenance to ensure that the fire doors work in accordance with the manufacturers design. The consequences of not maintaining fire doors could be deadly. Fire doors are designed in accordance with the building fire protection strategy to protect against fire and smoke and to provide safe evacuation of a building.

To ensure compliance of your fire doors, periodic checks must be carried out at least every six months. High traffic areas may require to be checked more frequently. The Regulatory reform (Fire Safety) Order 2005, states the requirements under the law to ensure fire resisting doors are installed and maintained correctly.
