What is Passive Fire Protection?
Passive Fire Protection (PFP)
Passive Fire Protection (PFP) is a vital component of any fire strategy. It is built into the structure of a building to safeguard people’s lives and limit the financial impact of damage to buildings and their contents. PFP does this by:
- Limiting the spread of fire and smoke by containing it in...
What is the difference between Reaction to Fire and Resistance to Fire?
Whether you’re a contractor, engineer, architect, or simply someone looking to find out more information on the subject, the two terms can often be confusing. There is, however, an important distinction between the two.
Reaction to fire evaluates specific materials contributing to fire, whereas resistance to fire assesses a...
What Fire Regulations are in Place Within the UK?

Fire regulations within the UK, are continuously being updated and improved to ensure the maximum protection for building structures and people. The regulatory reform (Fire Safety) 2005 (RRFSO) became law in October 2006, and changed the way that the fire safety of buildings is managed and enforced.

How far from a compartment wall should my services be supported?
Services should be supported in line with the installer and/or service manufacturers recommendations. Any deviation from this may result in warranty and liability changes.
It is generally assumed that services should be supported as per fire test, typically between 200mm and 500mm away from the compartment. We do not support...
I have plastic pipes that are less than 40mm in diameter, can they be fire stopped without a closing device?
The general consensus within the industry appears to be that combustible pipes & conduits with an Internal diameter of less than 40mm only requires to be fire stopped “up to”, with no requirement for a closer device.
Firetherm/Nullifire view the statement within Approved Document B (ADB) quite differently. Pipes with an...
There is a fire damper in the same openings as other services, how can this be fire stopped?
As ducts and dampers are tested to a different standard to cables, pipes etc. they should therefore be separated from other services and installed into their own openings.
First port of call should be to contact the duct or damper manufacturers, as their tested solutions would supersede our advice.
In the absence of this, or...
What is the Role of Compartmentalisation Within a Building Facing a Fire, and How is it Done?
Compartmentalisation
One of the fundamentals of passive fire protection is the compartmentalisation of buildings. To limit the spread of fire and smoke within a building we must compartmentalise: divide the space into several smaller sections in order to confine the fire in the only space it was declared, during the time...
