Active Fire Measured
Systems that require an action or motion in order to work (Smoke alarms, Fire Extinguisher, Sprinklers)
Passive Fire Measures
A fire resistant/protective barrier system
Fire triangle
Oxygen, Fuel, Heat (+ chemical reaction)
Building Regulations relating to fire?
TGD Part B Fire
1 Dwelling Houses: 2017
2 Buildings other than dwellings 2020
Fire engineering principles (BS 9999)
Fire engineering principles (BS 7974)
What passively protects the building from fire growth (reaction to fire)
Compartmentation / Fire resistance
Structural fire protection
What affects fire growth?
The choice of materials for walls and ceilings can significantly affect the spread of flame and it’s rate of growth.
What are two properties of lining materials that influence fire spread
The rate of flame spread over the surface when it’s subject to intense radiant heating
The rate at which the lining material gives off heat when burning
What test methods do BG classify products based on BS476 reaction to fire performance test methods
BS476 Part 4 (Non-Combustibility)
BS476 Part 6 (Fire-propagation)
BS476 Part 7 (Spread of flame)
What is contained in BS 7974
Fire Engineering Principles
What is contained in BS9999?
Fire design managment - like a building design risk assessment
What is BCAR?
The building control amendment regulations: 2015 which brought in the need for an assigned certifier
Active Fire Measures?
Detection and Suppression measures triggered by action, fire or smoke
Passive Fire Measures?
Containment, Preventing or slowing the spread of fire, maintaining the building structure, providing a safe passage of escape / a refuge.
What are passive measures reliant on?
The appropriate selection of materials, construction and design (& workmanship)
What are the 5 stages of fire?
Ignition Growth Flashover Fully Developed Decay
Why do walls need control measures?
To prevent the spread of flame into adjoining space
Why do ceilings need control measures?
To prevent the spread of flame into above space.
To prevent the potential collapse of a floor.
To prevent the ceiling collapsing and blocking an escape route
What are fire dampers?
Fire dampers are fitted where ductwork passes through fire compartment walls and fire curtains as part of a fire control strategy. In normal circumstances, these dampers are held open by means of fusible links. When subjected to heat, these links fracture and allow the damper to close under the influence of the integral closing spring. The links are attached to the damper such that the dampers can be released manually for testing purposes. The damper is provided with an access door in the adjacent ductworks for the purpose of inspection and resetting in the event of closure.
Are the building regulations formed around health and safety?
Yes, they are usually there for health and safety. Fire measures are there to let people escape and preserve their life (Or hold out long enough in a space for fire crews to put out a fire in an adjoining space)
Where are the minimum standards for fire located?
The current building regulations are the minimum standards. It is possible to go beyond minimum standards.
Are there different standards based on building types?
There are different requirements based on building size, type and occupancy.
Where are the requirements for fire resistance found?
In the appendix at the back of the TGD
What does it mean when a product is CE marked?
CE means that a product was manufactured in accordance with a harmonised EN standard (HEN)
In relation to CE marking, are there any requirements for fire testing?
CE marked products must have a “Reaction to Fire” declared in accordance with EN testing standards
