Question 1

How long do fire doors protect you for?

Accepted Answer

There are different grades of fire door, and each one provides a different level of protection. The grades are separated by how long they can withstand fire. The main ones are FD30 (30 minutes), FD60 (60 minutes) FD90 (90 minutes) and FD120 (120 minutes).

Question 2

Where are fire doors required?

Accepted Answer

All regulations pertaining to the use of fire doors are contained in Fire Safety: Approved Document B and following incorporations. According to the legislation, fire doors are required in domestic buildings over 2 storeys high; each door leading to a stairwell (at every level) from a habitable room (not a bathroom, for instance) must be a fire door. For commercial or non-domestic buildings, fire door requirements vary according to whether escape routes are vertical or horizontal (down stairs or through corridors).

Question 3

Who enforces the Regulatory Fire and Safety Order?

Accepted Answer

The Regulatory Fire Safety Order is enforced primarily by the area’s local Fire and Rescue Authority (FRA). However, other organisations may enforce fire safety regulations in special circumstances, such as the Health and Safety Executive (HSE) or the Secretary of State for Defence’s fire service. If you are unsure as to where your FRA is based, you can either contact your nearest fire service or consult the National Fire Chief’s Council website.

Question 4

What is fire protection?

Accepted Answer

The aim of a fire protection system is to safeguard a building’s occupants and minimise the damage associated with fire. Overall, the goal is to provide the widest possible window for a safe evacuation, whilst also reducing potential repair costs.

Fire protection systems can be categorised as either active or passive. While active systems are designed to detect and fight fires (such as fire alarms and sprinklers), passive fire protection describes the structural measures which prevent the passage of flames and smoke.

Question 5

What is fire prevention?

Accepted Answer

Fire prevention systems are put in place so a building’s fire load is as low as it can possibly be. ‘Fire load’ is a term used by fire protection professionals to gage the potential severity of a fire in a building, based on the presence of certain hazards. Essentially, fire prevention reduces the likelihood of a serious fire. By safely storing combustible materials, and taking care of points of ignition (such as heating systems and plug sockets), we are reducing the risks associated with fire.

Question 6

What is fire suppression?

Accepted Answer

The sole objective of a fire suppression system is to extinguish a fire as quickly as possible. 
Once occupants are alerted to the presence of a fire, the system will begin to emit a concentrated substance to suppress the flames. The exact nature of this substance can vary, based on the environment the system is designed to protect. Common examples include carbon dioxide and inert gas, as well as a range of both liquid and dry chemical agents.

Question 7

What is active fire protection

Accepted Answer

Fire protection measures categorised as ‘active fire protection’ all react to action or motion. Fire alarms, for instance, must be activated to bring attention to a fire. Similarly, a fire extinguisher must be actively used in order to put out a fire. Fire sprinklers are also an example of active fire protection. This is because they are automatically activated in order to suppress a fire.

Question 8

What is passive fire protection?

Accepted Answer

The term ‘passive fire protection’ describes structural measures implemented to prevent a fire from spreading within a building. Specialist contractors will be brought on as part of the building process to advise on passive fire protection measures, which can include compartmentation, firestopping and fireproofing using intumescent paint. According to Global Market Insights, the passive fire protection market is estimated to be worth $31 billion by 2026.

Question 9

Why is Concrete Resistant to Fire?

Accepted Answer

There are three main reasons why concrete has been categorised as one of the most fire-resistant materials; concrete is non-combustible, it’s non-toxic and it has low thermal conductivity. This means that it does not easily transfer thermal energy, and does not react easily with other substances (meaning that in the event of a fire there are no noxious gases released). This makes concrete one of the safest and most effective materials for structural fire protection.

Question 10

What were the changes to building regulations after Grenfell?

Accepted Answer

The biggest change to building regulations post-Grenfell was a proposed ban on the use of combustible materials in the external walls of residential buildings over 18 metres in height.
