RICS would generally only consider retrofitting to be necessary in higher-risk residential buildings in specific circumstances
How may a fire start in a building?
Faulty electrical wiring
Carelessness, e.g. discarding cigarettes, overloading electrical plugs
Arson
Cooking

You are designing a 4-story building and are looking at the fire safety as part of your design process. Which of these are measures you can consider to lower the fire risk to the premises?
Install lighting conductors
Limitation of the horizontal spread of smoke by the installation of smoke curtains
Install warning systems
Install sprinklers or other fire suppression systems
Ensuring that escape routes are easily accessible and are neither too long nor too complex
Use of fire containment to provide a place of safety within a building as a last resort
Install smoke vents
Ensure that there is adequate passive compartmentation
Resistance to the transfer of excessive heat, i.e. ability to provide insulation from high temperatures
Design out ignition sources
You are inspecting an office being built and want to pay particular attention to see if the fire doors have been installed correctly. What would you look for?
That the door is certified
The door frame has been be purchased from the fire door manufacturer or from a company licensed to manufacture them
The intumescent seals are in place, well attached inside the groove in the frame or door leaf, continuous around the frame and free from damage
That the door fully closes into the frame
The vision panels have been glazed
That the frame is correct
The correct glass has been fitted to any vision panel
That the gaps top and sides of the doors are less than 4mm from the frame
That the door is secured using three hinges, firmly fixed with all screws fitted. The screws should be the correct size and the hinges free from metal fragments and oil leakage
That a door closer has been fitted and that this is correctly attached and free from damage
The door closer is the correct model
If the doors are fitted with hold open devices, you would test them
That the door and frame are damage free
What are methods for the protection of structural steelwork from the effects of a fire?
Concrete
Spayed coatings
Intumescent paint
Cladding with fire resistant boards
What method has gained in popularity in the protection of structural steelwork?

Who, under the Regulatory Reform (Fire Safety) Order 2005, has the responsibility for undertaking the fire risk assessment?
The responsible person

Fire Safety Act 2021
Housing Act 2004
Name the factors which would be taken into account in conducting a fire risk assessment for a relatively new building
Fire detections systems and different categories of fire alarm
Fire suppression systems / devices and the different types of these
The number of and width of escape routes including the concept of discounting one stair for Means of Escape calculations
The length of escape routes
Compartmentalisation of escape routes
Smoke discharge systems
Sources of ignition
Sources of fuel
Compartmentalisation of the building
Emergency lighting of different types including where it is appropriate to use each type
Smoke extract ventilation
Escape route signage
Time it takes to get out of the building
